Device created by Dr. Leiter Greenbox that possessed the ability to repair any broken piece of technology. Upon repairing the Metallikats the device gained an evil sentience and took on the name Zed and began its quest for world domination. The original device was kept in a “control unit” called the heart chamber in the center of Zed’s chest until it was taken by Greenbox into the robot body’s brain center. The device was destroyed when T-Bone knocked it off of Greenbox’s interface helmet, smashing it on the floor, seemingly destroying the threat of Zed forever.
