Kolosolok were a warrior hive belonging to the Killik species. These creatures, measuring around fifty meters in length and ten meters in height, possessed the ability to withstand substantial damage. In the era of the Cold War, as the Colony forged an alliance with the Sith Empire, the Kolosolok held the strong belief that the Empire warranted annihilation. In the Swarm War, the Killiks employed them as heavily armored land vehicles, utilizing them to breach the defensive structures of the Chiss during the concluding phases of the Battle of Tenupe.
