|"Sometimes I wanna burn the whole world!"|
|Voice Artist:||Chris McCulloch|
Ro-Boy is a robot and a former boy adventurer, who took part in the boy adventurers' group therapy session to deal with his many anger issues, which probably came about after being abandoned by his creator/father. He gets very angry when he sees giant robots and occasionally wants to see the whole world burn.
Ro-Boy's known features include shooting lasers from his eyes, the ability to fly, and an on/off button on his crotch.
- Ro-Boy is a parody of Astro-Boy, another robot made to look like a child who has an array of hidden weapons, jets in his feet and has a habit of fighting giant robots.
