A famous pessimist and loner, Salaak is a creature of protocol and laws. A veteran Green Lantern, he has served in many Corps campaigns over the years. During the Crisis on Infinite Earths he protects multiple sectors, but found the experience depressing. After this, he went to Earth looking for company amongst his fellow Green Lanterns. He served with the contingent of Green Lanterns assigned to Earth and became good friends with Ch'p of H'lven. For a time Salaak lived in the future, filling the identity of Pol Manning as Hal Jordan had before him. While in the future, Salaak was married to a human woman.
Salaak returns to the present day to warn about the destruction of the Corps. He was too late to stop the execution of Sinestro. The Central Power Battery on Oa ends up destroyed, and with it, Salaak's ring is made inoperable. He finds transport to H'lven where he reunites with Ch'p, one of the few Lanterns whose ring still functioned. Salaak remains on H'lven and acts as Ch'p's advisor until they discover that the Guardians have returned and have rebuilt the Corps. The two later petition for reinstatement, but Ch'p is killed in a traffic accident. The Corps is destroyed again when Hal Jordan, crazed with grief at the loss of friends, became the entity known as Parallax. Hal's activities caused the shutdown of the Oan battery again and Salaak, along with all other Green Lanterns, were left powerless.
Salaak attends Hal's memorial service on Earth. The Corps, reformed again, has Salaak as the senior administrator and the Keeper of the Book of Oa. The Book tells of the adventures of multiple Green Lanterns throughout the history of the universe.
Salaak reinforces the squadron of Lanterns sent to save Mogo from Ranx the Sentient City and other Sinestro Corps members (Sinestro having returned from the dead). He has expressed displeasure at the fact that the Guardians have rewritten the Book of Oa to allow lethal force against members of the Sinestro Corps, but is still committed to serve.
He survived the Sinestro Corps War without major injuries, and he continues to hold onto his position as keeper of the Book of Oa. He is kept out of the loop in some instances by the Guardians who neglected to tell him their plans to create the Alpha Lanterns. More recently however he is seen getting into an argument with Guy Gardner over a bar he wishes to open. Salaak quickly disapproves, which leads Guy to use his ring to make a miniaturized version of Salaak mocking him for "hanging out with midgets".
Salaak is seen in Final Crisis #5 as part of the trial of Hal Jordan.
During the Blackest Night, Oa comes under siege from the Black Lantern Corps. With the Guardians missing, Salaak takes command of the Green Lantern Corps as Clarissi and thus the next in succession after the Guardians, preventing the Alpha Lanterns' attempt to take control. As his first command decision, Salaak decrees that all fallen Lantern rings be sent to Mogo, so as not to endanger any new recruits.
After the War of the Green Lanterns, Salaak went along with the Guardians' orders to prepare a space for Krona in the Green Lantern memorial hall despite the other Corps members' anger at such a decision, despite Salaak claiming that the Guardians want to remember the good that Krona did in helping to found the Corps rather than the evil he committed later, with the other Corps members denouncing him for his blind loyalty.

He also appears in Green Lantern: The Animated Series. He grew angry, along with Hal Jordan and Kilowog, when they found out that the Guardians had kept the other frontier Lantern deaths from the Corps. He later defends the Guardians when Atrocitus and Zilius Zox infiltrate Oa. He is able to deflect Zox's attack but is defeated when Atrocitus attacks him from behind. With what strength he had left, he opened the Guardians' chamber dome to allow Hal in to defeat Atrocitus. In the season finale, Salaak is seen coordinating the Corps against the Aya Monitor. He is voiced by Tom Kenny.
