The Controllers are a fictional extraterrestrial race existing in the DC Universe. They first appear in Adventure Comics #357 (June 1967), and were created by Jim Shooter, Mort Weisinger, and Curt Swan.

Pre-Crisis
In their initial appearance, the Controllers came from "another space-time continuum." Their universe had almost been destroyed by war, and they were determined to prevent the Earth-One universe from going the same way. They used their mind-control abilities to prevent intergalactic war, but also had powerful weapons, including the Sun-Eater. This concluded with "The Death of Ferro Lad" story where Ferro Lad dies destroying the Sun Eater.

Maltusians
The Controllers' origins were changed following the Crisis on Infinite Earths events. They were now originally part of a race of immortals called the Maltusians. These beings left Maltus and colonized a new world called Oa. Now calling themselves Oans, they feel responsible for the catastrophic effects on the universe caused by one of their own, the renegade scientist Krona. The group argues over ways to handle the situation. One group of Oans desires to dedicate their immortal existences to contain evil. This group eventually became the Guardians of the Universe. Another group decides that evil should be destroyed. This group leaves planet Oa, eventually becoming the Controllers. It is also revealed that the Controllers left over the Guardians' decision to not destroy their former robot minions, the Manhunters, after the Manhunter rebellion on Oa.

Just as the Guardians slowly changed their physical appearances over billions of years of existence, so did the Controllers. Originally, all Oans were blue-skinned humanoids; currently, the Controllers are pink-skinned and hairless. The Controllers moved to another dimension and dedicated themselves to creating weapons that could be used to destroy evil beings if they became too dangerous. Among these are the Sun-Eaters, gaseous beings that can devour whole planets and stars, and the Miracle Machine, a device that can turn any thought into reality.

Controlling The Darkstars
The Controllers eventually recognized the benefits of having a law-enforcement agency at their disposal and formed the Network for the Establishment and Maintenance of Order (NEMO). Their agents were the Darkstars, armed with crimson exo-mantle that was powered by the Controllers' own energy. Many former members of the Green Lantern Corps joined the Darkstars after the Corps was destroyed. As time went on, the Controllers expressed concerns about the effectiveness of the Darkstars. More specifically, they were troubled that Darkstar agents were mostly looking after their own agendas rather than those of the Controllers. They withdrew their support from the Darkstars. This made many of the early Darkstar uniforms useless, as they relied on energy transmitted from the Controllers. The Darkstars are now defunct; most had been slain by the forces of Grayven.

Other Endeavors
In their continuing effort to create an alternative to the Green Lantern Corps, the Controllers experiment on Martyn Van Wyck, transforming him into the pyro-kinetic Effigy. Their plans to create an entire organization of such beings, all brainwashed to serve the Controllers, was underway before Kyle Rayner learned of the plan and convinced the immortals to abandon it. An unnamed Controller was featured in Power Company issues #12-14, where he is a prisoner of Doctor Polaris. The Power Company eventually succeeds in freeing him. He tells the group that his original reason for visiting the Earth was an attempt to re-secure a cosmic artifact called the "Mephistopheles Matrix."
In the series, Trinity, a group of Controllers discover a Krona freed of his Cosmic Egg and aid him; though, when their treachery is discovered by Krona they are promptly eliminated.
In the Final Crisis storyline, the Controllers were revealed to survive into the 29th century, at which time they develop the Miracle Machine, whose schematics Superman memorizes upon a visit to the 31st century.
In the Blackest Night storyline, a small group of Controllers appeared in search of the "orange light of avarice," hoping to create their own Corps. This group locates the orange light on the planet Okaara, but they are slaughtered by Larfleeze, and assimilated as constructs in his Orange Lantern Corps.

Powers and weapons
The Controllers are immortal, like all Oans. They can manipulate energy and create vast technology and weapons. Their most known weapons are The Sun-Eater, The Miracle Machine, and The Darkstar exo-mantle.

Other versions
In the future of the Legion of Super-Heroes, a renegade Controller became the villain known as the Time Trapper. Various DC Comics reboots have since altered this timeline, which is one of many origins given for the Time Trapper. The Controllers also ended up giving the Miracle Machine to the Legion for safekeeping.

In other media
Television
A Pre-Crisis Controller appears in the two-part Legion of Super-Heroes episode "Sundown" voiced by David Lodge. This renegade Controller believes that the ultimate perfection comes from chaos, rather than order, and releases the last Sun-Eater to spread this chaos. Superman was sent to stop him on his own while the Legion stops the Sun-Eater. The Controller's plan was foiled, but at the cost of the Legion member Ferro Lad's life. As he makes his escape, Superman warns him to never appear again.
The Controllers briefly appear in the Batman: The Brave and the Bold episode "When OMAC Attacks." Batman alongside Hawk and Dove had to stop a war between the Controllers and the Warlords of Okaara.

Nekron is a comic book supervillain appearing in books published by DC Comics, specifically those related to Green Lantern. Created by Mike W. Barr, Len Wein and Joe Staton, the character, who exists as an embodiment of Death, first appeared in Tales of the Green Lantern Corps (vol. 1) #2 (June 1981). He is the primary antagonist in the "Blackest Night" storyline that was published in 2009 and 2010.

Origins
Nekron is a fictional embodiment of Death and ruler of a region adjoining Hell that also seems to border on Limbo and Purgatory within the DC Universe. It is where the souls of the dead await passage to their final residence in either the Silver City or Hell. Nekron draws his power from the souls and spirits of all those who have ever died.
After the Oan scientist Krona was sentenced to banishment as pure energy, that energy somehow reached Nekron's realm; a rift opens between the dimensions due to the paradox of an immortal now being in the Realm of the Dead. Desiring the living world he is now able to see, but being too large to pass through the rift, Nekron recreates Krona as an undead being of enormous power instead. Given an army of similarly-restored spirits, Nekron sends Krona to kill the Guardians of the Universe in order to increase the size of the rift. Krona cooperates because part of Nekron's plan involves collapsing the universe so as to recreate it according to his own desires (which would give Krona the chance to see a universe being born). Krona and his minions kill several Guardians and Green Lanterns while destroying the Central Power Battery to prevent the Lanterns from recharging their power rings. Although his attack is powerful enough to shatter the morale of the Green Lantern Corps, Hal Jordan manages to inspire and rally his fellow Lanterns into attacking Krona with the charge still left in their rings. Nekron is defeated when Jordan enters the realm of the dead and incites the spirits of the recently-killed Lanterns to rebel against him. This distraction undercuts Krona's power supplied by the being and thus gives the Guardians enough time to banish Krona into the dead realm and close the rift with Jordan still trapped inside. The spirit of Jordan's predecessor, Abin Sur, helps him escape the realm.

1990 - 2002
Captain Atom has a run-in with Nekron in which he is described as "Death as the Ultimate Opponent". Black Racer, also making an appearance, is coined "Death as an Inevitability", while Death (prominently known from her appearances in Vertigo titles) represents "Death as the Release, as Mercy, as Compassion." Drawing into the Quantum field, Captain Atom is able to get the better of Nekron and is able to visit his deceased wife.
Nekron later battles the demon Nebiros, following the destruction of Doctor Fate's Tower Of Fate. Also appearing in this issue is Jared Stevens (Fate).
Kyle Rayner later encounters Nekron when he nearly reenters the living universe when the level of supernatural activity mysteriously increases. This increase gave Nekron the opportunity to briefly control every deceased member of the Green Lantern Corps, which act as both his army and his anchor to the living universe. Kyle was able to push Nekron back into his dimension by freeing the undead Lanterns from Nekron's control. The rift is eventually sealed following Nekron's defeat.
Nekron also encounters Wonder Woman and Rebecca Carstairs (Witchfire).

"Blackest Night"
In the "Blackest Night" storyline, Nekron is revealed to be responsible for the creation of the black power rings, which reanimate the dead, and is collaborating with Scar and Black Hand. He's also responsible for the imprisonment of the Anti-Monitor during the aftermath of the Sinestro Corps War on the planet Ryut. When the Black Lanterns' power levels reach one hundred percent, he rises from the Earth, just outside of Coast City. Nekron is also revealed to be the true mastermind behind the miraculous resurrections of several superheroes in the past (a deed previously thought to be a consequence of Brother Blood tampering with the forces of life and death). By "allowing" the dead heroes to be reborn he grants himself a small cadre of "inside agents"; by briefly reanimating Batman's clone (created by Darkseid during Final Crisis and implied that the dark lord's awareness of the remains is not authentic) as an emotional tether to stimulate a powerful enough emotional response, Nekron is able to create black rings that latch on to Superman, Wonder Woman, Donna Troy, Kid Flash, Animal Man, Ice, Green Arrow and Superboy, transforming them all into Black Lanterns; Hal Jordan and Barry Allen are similarly targeted, but evade sharing their comrades' fates thanks to Barry taking himself and Hal two seconds into the future and causing their would-be rings to shut down.

According to Black Lantern Jean Loring, when the Guardians first harnessed the Emotional spectrum, Nekron was formed out of the nothingness in existence prior to the creation of the universe as a defense mechanism, the Guardian of Darkness. Given shape in the form of life's idea of death, Nekron marches with his undead army, claiming the hunger plaguing him has not abated. Nekron is not a living being but just exists as an avatar of darkness from the beginning of the universe. This makes Nekron immune to the Spectre's divine wrath, as he has no soul to judge.
Nekron begins to reveal the full extent of his plan. Nekron and his Black Lanterns bring the subdued Guardians to a clearing where the same symbol that was seen on Professor Zoom's chest is drawn in what appears to be blood. After questioning one of the Guardians and getting him to admit that he can no longer remember why the Guardians took a vow to protect the universe, Nekron slits his throat and Black Hand removes his organs and places them in the center of the symbol. After crushing the organs with his scythe, Nekron calls forth The Entity. The Entity is the white light given physical form. When Nekron strikes the Entity every living thing in the universe cries out in pain, this is because the Entity is what gave birth to life and all living things came from it. Nekron intends to kill the Entity and thereby kill every living thing in the universe. His plans, however, are thwarted when Sinestro bonds with the Entity becoming a White Lantern.

Another failure comes when the massed Corps above Earth reach Xanshi's core through its surface faults, and manage to destroy the thousands of rings holding it together. As Xanshi collapses, Nekron cries out in pain. While he also manages to nearly hack Sinestro in half with his scythe, he fails to kill him, and the White Lantern rises again, healing his wounds and promising retribution to Nekron.

In the battle that follows, the Life Entity eventually abandons Sinestro, refusing to be controlled by his ego, and bonds itself to Hal Jordan, who states that Nekron merely opened the doors between life and death while it was still the heroes' choices to return to life. Hal turns the power of The Entity on Black Hand (Deadman having discovered that Black Hand functions as Nekron's link to the living world), causing Black Hand to return to life and vomiting one white power ring that enters the Black Power Battery and resurrects the Anti-Monitor (destroying the Power Battery in the process), who immediately attacks Nekron. Nekron then returns the Anti-Monitor to the Anti-Matter universe. Twelve other white rings are then released by Black Hand and seek out several deceased heroes and villains who had been recruited into the Black Lantern Corps and turns them into White Lanterns instead. In the final confrontation that follows, Nekron is banished yet again, with Hal Jordan and Barry Allen speculating that death will now be more permanent with Nekron's plan having failed.

"Brightest Day"
At the conclusion of the miniseries Brightest Day, Swamp Thing appears, grown to towering size and emerging from the forest at the former heart of Star City, which has become corrupted. The White Lantern Entity explains that just as the memories of Alec Holland acted as a template for the Earth Elemental, the personality of Nekron has been imprinted over it. The corrupted Swamp Thing does battle with Alec Holland (having been resurrected and turned into the new Swamp Thing by the White Lantern Entity), who is aided by embodiments of the four elements (Hawkman, Hawkwoman, Firestorm, Aquaman and the Martian Manhunter) and is defeated, driving out the influence of Nekron once again.

Powers and abilities
The limitations of Nekron's powers are unknown. Geoff Johns has described him as the most powerful dark force in the DC Universe. He has displayed the ability to raise the dead, kill (even Guardians) with a touch, fire bolts of black lightning and grow without limit. He is also capable of fighting against universal forces like the Life Entity, who was bonded with Sinestro. Nekron also has incredible durability and reality warping powers, as he was able to withstand a blast from the Anti-Monitor and send him back to the anti-matter universe.

Other versions
In the alternate timeline of the Flashpoint storyline, it is revealed that Nekron was unleashed into the Universe when Atrocitus killed William Hand. Where Nekron and his Black Lanterns waged war is left unknown. All that is known is that the Guardians of the Universe tasked Abin Sur the mission to travel to Earth and recover the White Entity and bring it to Oa.

Boodikka is a fictional character featured in comic books published by DC Comics. Boodikka is a tall, well-muscled humanoid alien female with pink skin and reddish black hair. Her name is a play on the ancient British warrior-queen Boudica.

Fictional character biography
At three centuries of age, the warrior Boodikka of the planet Bellatrix was originally recruited by the sphere-like Chaselon of Barrio III to join the then-reconstituted Green Lantern Corps. Not long before, Boodikka had belonged to something called the "Bellatrix Bombers", a group of women mercenaries for hire by planets to clear the spaceways of hostile forces. The "Bellatrix Bombers" had broken up at some point, the majority of the team apparently having been killed along the way.
Initially Hal Jordan was dismayed and otherwise put off by Boodikka's inherently aggressive attitude. Nevertheless, despite this, Kilowog, a renowned trainer in the Corps – the first trainer of Jordan himself – (the original Green Lantern: Emerald Dawn), was only too eager to train someone so challenging and gave her his recommendation as a candidate. Jordan, it seemed, did indeed reject her. Things moved quickly at this point, and Boodikka soon found herself thrust into battle with Star Sapphire. She and the rest of the Corps joined in the fight against Hal's one-time love, the mercenary Flicker, and an entire Teban convoy.
Some time later, new recruits of the Green Lantern Corps were shown the Book of Oa, a book kept by the Guardians of the Universe which told tales of Green Lanterns past, present, and future. They learned stories which would help them be better Green Lanterns. Kilowog spent time with the recruits, telling them more stories of the Corps during their training. The new members had this training disrupted when they went to Earth to help free Hal Jordan from the influence of the villain Eclipso. They were no match for the eclipsed Jordan and Star Sapphire. Eclipso managed to escape the Corps and soon they returned to Oa. Guy Gardner was awarded a ring by the Guardians of the Universe to act as temporary Green Lantern of Space Sector 2814.
She would quickly prove to be a skilled power ring wielder, a worthwhile addition to the Green Lantern Corps. Nevertheless, her problem with authority and authority figures would still pose a continuing problem. She was often at odds with Kreon of Tebis, another new recruit to the Corps. As the former Chieftain of the Teban battle fleet, he was used to discipline and military precision. Their infighting had even jeopardized Oa and the Guardians during a Qwardian invasion. Guy Gardner had returned to Oa to take the yellow power ring of Sinestro. Without Kilowog to guide them, the Green Lanterns were in chaos. Their trainer had gone to Earth to help free Hal from Eclipso. Gardner fought the Qwardians where the Green Lanterns could not.

Kreon
Kreon and Boodikka came to blows when the rival Green Lantern criticized her for being an undisciplined fighter. Kilowog then separated them, but their disagreement seemed to be spreading amongst the rest of the Corps with sides being drawn between male and female recruits. Running out of options, Kilowog brought the two squabbling Green Lanterns to John Stewart as a "guest lecturer" in cooperation and tolerance. Stewart could not teach the two Green Lanterns to like each other, but he could teach them to need each other. Taking the initiative he performed a mind scan on the two recruits and somehow exchanged their consciousnesses. The two Green Lanterns were taken one step out of reality.
Soon, each came face to face with their ultimate fears. The fear of Kreon was represented by "Mama Denata" and seemed to represent his fear of the uncontrollable. Boodikka's fear was "the Chain Men" which represented the suffocation she felt by authoritative restraints. The two – independently – seemed to be unable to directly fight their fears. Instead, the two had no choice but to learn to work together or be defeated. Boodikka had no problem handling Kreon's nemesis and called upon him to return the favor and defeat "Mama Denata" and assist her. Kreon also did not suspect he would have much trouble with "the Chain Men" and accepted Boodikka's offer. The two rivals exchanged nemeses and were triumphant... and a newfound respect was born.
Boodikka never lost her love of battle. She eagerly fought against the incarnation of Entropy, even though the encounter then-seemed to mean certain death. Boodikka proved to have come a long way as a Green Lantern, then working as a team with the other members of the Corps to defeat Entropy.
In a space sector far removed from our own galaxy, Boodikka was assigned to investigate the deaths of multiple alien races. These numerous races had suddenly destroyed themselves in an apparent mass-suicide, environmental destruction, or otherwise massive wars. Upon arriving on a world already in the midst of tearing itself apart, Boodikka encountered Guy Gardner. He and his colleagues, the "Gardners of the Universe," had been dispatched to solve the same problem as Boodikka.
Guy sought to prove to his leadership abilities to his team of super-powered aliens from across known space. It was not long until Gardner got into an altercation with the Green Lantern. It was during this fight that Guy realized his yellow ring was powered by the energy of the Green Lanterns' power rings. Fully charged then, Gardner's yellow power ring enabled him to recognize the true threat. Created in the anti-matter universe of Qward, his power ring negated the mental block of the real attackers. Gardner used his ring to free the others from their trance. He would learn the true story from a native.
Boodikka's respite would not last long. An alien race called the Ophidians had come to cleanse known space. On two occasions in their sordid past they had been nearly annihilated by alien invaders – then since confining themselves to eradicating all other life in the universe to insure their pseudo-religious quest would never again be in harm's way. The Ophidians would entrance their victims before causing them to fight amongst themselves all the way to extinction. As the Ophidian ship managed to elude them, Boodikka and Gardner had to join their minds together to achieve the speed needed to overtake them. When they reached the ship, it exploded. Whether this was a result of feedback from the two fighting off the mind control or self-destruction, is unknown. The pair now had no way to find the Ophidian's homeworld. After the battle, Boodikka called upon the Guardians of the Universe to consult in the matter of recovering Gardner's Qwardian power ring. The Guardians, however, had determined Gardner was working toward the same ends they were. Although they would be watching Gardner, they decided not to act on Gardner for the time being.

A fierce warrior, Boodikka was well-versed in many combative arts including the use of short-swords, handguns, and explosives. Often she would visit her own mother for combat. On Bellatrix, this was considered a good time. Boodikka's own grandmother had been killed by her own daughter. Arisia, a former Green Lantern of Graxos IV and onetime love of Hal Jordan, told this story to Justice Leaguers Power Girl, Doctor Light, and Maya when they inquired about women in the Green Lantern Corps.
At one point the Green Lantern Corps were called upon to help Hal Jordan on the planet Maltus. He had been fighting the Maltusian gods known as the Triarch and was also under attack by the Darkstars and the L.E.G.I.O.N. Boodikka was as smitten as any Bellatrix women would be regarding the fighting prowess of Lobo, bounty hunter and L.E.G.I.O.N. operative. The two stopped in mid-fight and went "somewhere" at Lobo's suggestion for a formidable love-making session that would last some time. Lobo did not take kindly to interruptions, and the two of them missed the entire fight.
Adding to her existing duties, Boodikka eventually became a kind of recruiter for the Corps. In her search she would encounter Barin, a young soldier of a kindred warrior species who she believed would prove to be an asset to her brethren. As events would turn out, Barin was not quite at a point where he was ready to fight solo. Upon his first outing alone he was quickly besieged by a kind of space mongrels. Overwhelmed, Barin went into shock. Kilowog found him in a comatose state. The would-be Lantern was brought to Oa where he was connected to life support systems. Since the destruction of Oa by both the Parallax-ridden Hal Jordan and its resurrection by Kyle Rayner, Barin's ultimate fate remains unknown.

Emerald Twilight and beyond
Her next mission was to stop Hal Jordan from reaching Oa during Emerald Twilight by the direct order of the Guardians of the Universe. Although she fought well, she was no match for Jordan's willpower. Because she was unwilling to give up her ring freely, Jordan severed Boodikka's hand to take her ring from it. Jordan left her floating in space, who continued on towards Oa where he would soon become Parallax entirely. Jordan later mentioned that he had left Boodikka, along with the other Green Lanterns he had confronted on the way to Oa, with "enough power to survive" even after taking their rings.
Later it was revealed that Boodikka had indeed survived, joining "The Brotherhood of the Cold Flame" on the planet Xudar with other former Green Lanterns to find the means to atone for the crimes of Hal Jordan during Emerald Twilight. "After the utter rape and destruction of our brothers and sisters in the Corps, we survivors found one another and pledged an oath – to bind together in honor of the fallen, doing all that we could to heal the scars of the past," she told Tom Kalmaku, the longtime confidant of Hal Jordan. The Brotherhood of the Cold flame, using the spirit of the deceased Kilowog, created the "Dark Lantern," an instrument of their vengeance against Boodikka's wishes.
Boodikka was later discovered by Hal Jordan and Guy Gardner on the Manhunter homeworld of Biot, in a state of suspended animation with other Green Lanterns – including Ke'Haan, Laira, Kreon, Graf Toren, Jack T. Chance, and Hannu the Lost Lanterns – Hal Jordan had left for dead during Emerald Twilight. At some point in time the Manhunters, in concert with Hank Henshaw, had gathered up these former Green Lanterns, put them into suspended animation, and used their energies as a battery to create more advanced Manhunters. Strangely, upon being freed from her slumber Boodikka seemed shocked that she no longer had her hand, and following commentary implied her last conscious memory was of fighting the Parallax-possessed Hal Jordan despite having lived some time after her maiming (and free of any kind of captivity) on Xudar as part of the "Brotherhood of the Cold Flame". How or why Boodikka was captured while on Xudar (assuming she still remained there) remains unknown. During the confrontation with the Manhunters, Kreon dies and his ring chooses Boodikka. She resumes her duties in the Green Lantern Corps, replacing her lost hand with an emerald one fueled by her Power Ring energies.
Boodikka and her fellow Lost Lanterns kept their distance from Hal Jordan, until Parallax (in the form of Kyle Rayner) brought him to Qward, and they followed, knowing that "The Corps doesn't abandon its own". When Parallax killed Chance, she attempted to vaporise him, which her ring recognised as an illegal action, consequently shutting down, leaving her helpless. Boodikka then went with Ke'Haan and Laira to find Ion, deep beneath Qward. Instead, they run into the Anti-Monitor. Ke'Haan was killed, but the others managed to rescue Ion, and return to Oa. At the same time, the Guardians had rewritten the Book of Oa, allowing Lanterns to use lethal force, returning control of the ring to Boodikka.

Post-Sinestro Corps War
Boodikka became a member of the Alpha Lanterns, an internal policing force within the Corps itself, soon after the Sinestro War and the enactment of the Second Law of the Book of Oa. The Alpha Lanterns make sure that no Corps member performs an illegal action using a power ring. Each Alpha Lantern receives a second power ring and receives direct connections to the Book of Oa's Laws and the Central Power Battery. However, the process involves surgical alteration into a hybrid of the individual recruit's biological form and updated Manhunter technology. In other words, Alpha Lanterns are cyborgs.
Boodikka and the Alpha Lanterns are seen in Final Crisis. Fellow Alpha Lantern Kraken is revealed to be taken over by Granny Goodness during Hal Jordan's trial after the Alphas had arrested Hal for the murder of Orion.

Brightest Day
Alpha Lantern Boodikka is shown to have been controlled by Cyborg Superman. As she attacks Kyle Rayner, Soranik Natu, and John Stewart, Green Lantern member Hannu ambushes her and manages to damage her severely. This temporarily frees her from Cyborg Superman's control and she instructs the other Lanterns to recharge the battery with the energy she has absorbed. Her fellow Lanterns are able to repair her enough for her to fight, and she joins in the attack on the Cyborg Superman's base. During the battle, the Cyborg's body is destroyed, and his consciousness attempts to take control of Boodikka's body. Boodikka's consciousness fights back, defeating him. On her return to Oa, Boodikka is made a member of the Lantern Honor Guard, her emotions restored due to the way she was freed from the Cyborg's control. However, Ganthet noted immediately that there was something different about her. Boodikka asserts this is because Ganthet's newly discovered emotions allowed her to be who she is (Boodikka's true self, now in control of her body again), not what she is (an Alpha Lantern).

Reign of Doomsday
Boodikka later appears at the remains of the destroyed planet New Krypton, where she encounters Batman and Supergirl of the Justice League. Boodikka explains that the Guardians had sent her on a mission to survey the ruins as a follow-up to the initial Green Lantern Corps inspection of the planet that took place during the World of New Krypton storyline. Suddenly, the heroes are attacked by Doomsday, who strikes Boodikka across the back before she has a chance to react. Due to her injuries, Boodikka is unable to effectively wield her ring, and is nearly captured by the creature before being rescued by Supergirl. With Starman and Saint Walker of the Blue Lantern Corps serving as a distraction, Batman and Supergirl are able to get the injured Boodikka to the JLA Watchtower. Doomsday follows them aboard, and just as he is about to attack them, Cyborg Superman emerges from Boodikka's body and states that Doomsday attacked Boodikka and the JLA members in order to get to him.
After Doomsday captures Supergirl and Cyborg Superman and then flees the Watchtower, Starman mentions that Boodikka is healing herself in the JLA medical facility, and that she should soon have enough energy to return to Oa.
Following the War of the Green Lanterns storyline, Boodikka and the Alpha Lanterns were killed by Alpha Lantern Varix that who felt that the Alpha Lanterns were being corrupted into judgement against John Stewart during his trial, Varix then killed himself. Afterwards, the bodies of Alpha Lanterns were interned on Oa.

In other media
Television
Boodikka appears briefly in the Duck Dodgers episode "The Green Loontern" as one of the Lanterns defending Oa from Sinestro, voiced by Grey DeLisle. She is later rescued by Dodgers and the rest of the Corps.
Film
Boodikka appears in Green Lantern: First Flight voiced by Tricia Helfer. This version of Boodikka is radically different from her comic version, in that she is a co-conspirator with Sinestro. In a fight with Hal Jordan and Kilowog, she is killed when impaled after an explosion.
Boodikka has a cameo appearance in Green Lantern: Emerald Knights, reprised by Grey DeLisle who was uncredited for the role.
Boodikka also appears in the live-action Green Lantern film in a cameo in a few scenes in the film. Although she is very similar to humans in appearance in the comics, no actress was cast for the role and CGI was used instead, to portray her.

Jack T. Chance is a fictional character featured in comic books published by DC Comics. He is a Green Lantern from the world of Garnet—also known as Hellhole. Physically, he is a tall, blue-skinned humanoid. Other distinguishing features include a trademark trench coat, what appear to be brown leather pants, and a skull around his neck. He first appears in Green Lantern Corps Quarterly #1 in the summer of 1992. The story was entitled "Layin' Down the Law".
Created by John Ostrander, Chance is loosely based upon another Ostrander character named GrimJack.

Fictional character biography
Green Lantern of Garnet
Jack T. Chance is from the planet Garnet, also known as 'Hellhole' because it is one of the worst criminal worlds in existence. Repeatedly the Guardians of the Universe dispatched Green Lanterns to this planet in hope of redeeming the world, but each attempt ended in failure, usually fatally for the Green Lantern. The last Guardian-sent agent, Pathavim Seth-Ottarak, used his dying breath to instruct his ring to find a replacement among Hellhole's inhabitants uniquely suited to the challenges of the world (in other words, one not limited by the Green Lanterns' usual moral strictures). The ring chose Jack T. Chance. When the ring bonded with him it created a standard Green Lantern uniform and explained his duties to him. Chance rejected the idea of a uniform, refusing to wear anything other than his own trashy clothes with a single small added badge.
Chance hunted down the man who killed his predecessor, intending to kill him in turn, only to find the ring had a failsafe against lethal force. Further, the ring offered no protection against his opponent's yellow bullets. Thus Chance fell back on traditional methods and used a crude firearm to shoot the man dead. This became Jack's standard methodology as he went about pacifying Garnet, wearing down his targets with the powers of the ring then delivering a killing blow with a sidearm.

When news of this reached the Guardians, Chance was quickly recalled to Oa for judgement. The Guardians decided Chance would be subjected to rigorous training and a probationary period before he was allowed to continue serving with the Green Lantern Corps. Chance in turn threatened to simply quit if forced to play by their rules and pointed out his brutal approach was the first thing that had ever worked on Hellhole. The Guardians conceded they lacked a suitable alternative candidate to serve as Garnet's Green Lantern, and had no choice but to appoint Chance as Green Lantern of his planet. Chance and the Guardians brokered a deal whereby he was restricted to his planet (other Lanterns covered whole sectors). His deeds were also subject to reviews to ensure he was not using 'questionable methods'.
Sometime later, while doing his duties on Garnet, he had the displeasure of encountering Lobo, and true to form the two got into a fight. Chance had the upper hand because of his ring and was enjoying the one-sided fight. The fight took a turn for the worse when Lobo realized that the ring had a weakness to yellow. Lobo covered himself in the yellow blood of a downed citizen, and defeated Chance. Knowing that he would be in a bad way when Lobo was finished with him, he ordered his ring not to forget anything important when the ring would put him back together. After winning the fight, Lobo had the idea of taking Chance's power ring before he left 'Hellhole', however, the ring could not be removed from its wielder's finger. Consequently, Lobo took the whole finger. As Lobo walked off, the ring informed him that, due to the specific deal the Guardians had made with Chance, it would not work beyond the parameters of Garnet's atmosphere. Disappointed, Lobo tossed the finger and ring, and left the planet. The ring and finger then made their way back to Chance and reattached themselves.

Emerald Twilight
When Hal Jordan went rogue and headed for Oa, the guardians were desperate and called Chance, as their most 'ruthless' agent, to stop the rampaging Jordan. To this end they granted his ring the same abilities as other members of the Corps, and its power was no longer limited to Garnet's atmosphere. While he did manage to surprise Jordan, his skill proved insufficient against his enemy's superior ability. Jordan took the rings from Chance and the other Green Lanterns, and left them for dead.

Return and death
However, Chance did not die, and instead was captured along with fellow Lost Lanterns, to be used by the Manhunters as energy for their newly upgraded software. He was freed by Hal Jordan and Guy Gardner and received a hero's welcome upon his return to Oa. Even though he and his fellow Lost Lanterns were aware that Hal Jordan's murderous actions were the result of the influence from the fear-inducing parasitic energy entity known as Parallax, they still bore grudges and remained unwilling to trust him again. Chance's return made the Guardians rethink his status as a probationary member, and he was finally accepted in the ranks of the Green Lantern Corps.

Chance and his fellow Lost Lanterns were all in the mess hall when the torchbearer Ion was whisked away by a yellow lantern ring during the Sinestro Corps attack on Oa. Jack and a select few Green Lanterns were sent to Qward to rescue Hal Jordan and the Green Lanterns of Earth. While on Qward they discovered the Torchbearer Kyle Rayner was now possessed by the fear entity Parallax, which had turned him as murderous as Hal was. Jack then confronted Parallax and was forced to experience his repressed fear of an abusive family/childhood. The Parallax-possessed Rayner then killed Chance and crushed his ring.

Blackest Night
As part of the Blackest Night event, all of the fallen Green Lanterns in the Oan crypt are reanimated by black power rings in Green Lantern Corps (vol. 2) #39 (October 2009). Chance is among the many Black Lanterns shown standing against the Green Lanterns on Oa.

Personal oath
You who are wicked, evil and mean
I'm the nastiest creep you've ever seen!
Come one, come all, put up a fight
I'll pound your butts with Green Lantern's light!
Yowza.
