Cyclops

Cyclops, or CC by Sarge, is a large Mantis-class military assault droid that was located inside the UNSC Crashed Ship.

Role in Plot
In Finders Keepers, Sarge, Grif, and Doc venture inside the crashed ship in search for something that can destroy Freckles, the Blue Team's Mantis. During their search they discover a large Mantis, dismantle it, and take it back to Red base. However, Grif loses various parts of the robot on their way back, forcing Sarge to use the parts he has to reconstruct the robot. When activated, Cyclops states her name and threatens the Reds, before deactivating.
