Robotboy
From Finsters Place For Made Up People The Tbs Wiki
Robotboy is a battle robot with three modes of operation: Deactivated, Activated, and Superactivated. Deactivation mode is Robotboy's standby stage, where he becomes compact enough to fit into a backpack. Activation mode is the standard stage of Robotboy's active modes, where he is able to use most of his non-battle technology. Superactivation mode is when Robotboy transforms into his battle stage of operation, where he has access to an amazing arsenal of weaponry to deal with any and all enemies.
Robotboy is mainly a fun loving robot, with the ability to have human-like emotions and actions despite being mostly machinery. He acquires human skin in season 2 of Toxica's Bonus Stage
