A Frankenstein's monster-esque robot, Kolossal/Scavenger is the brute of Dr. K's forces. Not too intelligent and continuously relies on his master for orders but almost equal to Cubix in fighting ability, Kolossal/Scavenger serves as Cubix's nemesis in the early part of the show. Kolossal/Scavenger's equipped with various weapons but most importantly a detachable floating platform on his left shoulder where Dr. K. takes seat. Kolossal/Scavenger is big and strong, although bulky he is capable of limited flight and agile high jumps, his left hand is a sort of claw that can be launched to grab things from afar. Most of the time he uses only brute force to win. Without his master's continuous coordination however he can only complete basic tasks.
In the Original Korean Version, His name is Scavenger and He is very Silent and Voiceless, But in 4 Kids Entertainment English Version, He speaks with a Bulky Voice and says "Kolossal, Destroy!"
