Crazed ratbot. Originally created by a black market company, The Rat was one of many droids built for assassination. Unlike the previous versions, however, The Rat was designed as a Reploid and was outfitted with various weapons to outdo the rest. Since he was a Reploid The Rat's mind began to change and he quickly went Maverick, doing things his own way before finally destroying the very company that created him. Although most people thought The Rat was also destroyed, Yuber managed to find and reactivate the Reploid, allowing it to go on another destructive rampage.

The Rat first appeared in Series 4, Epilogue #39 "Rampage of The Rat".

A dead robot. Dead Man does his job well. He plays dead. Since he always plays dead no one ever bothers him which is why a robot from the 20XX era is still around in the 21XX era. Another reason is because despite being a robot, Dead Man can create a magic-based barrier that repels anything and everything that comes near him. He somehow became The Rat's only friend and together with R.O.B. form an unlikely team of powerhouses.

Robotic Operating Buddy. R.O.B. acts as The Rat's assistant by repairing him whenever he becomes heavily damaged.
