SALAAK
REAL NAME: Salaak
OCCUPATION: Green Lantern/Galactic Protector/Clarissi/Keeper of the Book of Oa
BASE OF OPERATIONS: Sector 1418 re-assigned to Sector 0
HOMEWORLD: Slyggia
HEIGHT: 7′6″
WEIGHT: 207 lbs.
EYES: White
HAIR: None
FIRST APPEARANCE: Green Lantern Vol. 2 #149 (February 1982)
AKA: Green Lantern
BACKGROUND from the comic books:
In an odd coincidence, Slyggia occupies the space Sector closest to Korugar, homeworld of Sinestro, especially when you consider both beings passion for order.
Currently, Salaak serves one prime Sector, Zero. At the heart of the Universe within the very Citadel of the Guardians, the stoic Slyggian acts as tactician for the GL Corps relaying the orders of their blue masters as well as passing on any revisions to the sacred Book of Oa that will affect a Green Lantern on duty. One of these was the amendment that allowed the use of Lethal Force during the Sinestro Corps War.
Salaak’s almost emotionless demeanor would suggest that this longtime veteran of the Corps does not care about his fellow GLs, but quite the opposite is true. With no connection to his homeworld or Sector, the Slyggian sought the companionship of other Green Lanterns and based himself on Earth for a time. He made many friends there, although he does not always understand or agree with Hal Jordan’s emotional outbursts. He has settled on staying in Sector 0 and serving the Guardians there.
Attributes:
Pessimistic, always sees the downside of a mission.
Meticulous to a fault, currently his charge requires him to be aware of what every Green Lantern is doing.
Loyal, the Guardians of the Universe could not have asked for a better servant.
Highly intelligent and makes calculated decisions rather than allowing sentimentality to get in the way.
Four-armed, he is quite the multi-tasker.
Ring creations are precise with nothing wasted on over-imagining them.
