Kolosolok was a Killik hive of warriors. They were approximately fifty meters long by ten meters tall, and could take massive amounts of damage. During the Cold War, when the Colony was developing an alliance with the Sith Empire, the Kolosolok were of the opinion that the Empire should be destroyed. During the Swarm War, they were used as armored ground vehicles by the Killiks and were used to break through the Chiss' defensive fortifications during the last stages of the Battle of Tenupe.
