The main character from the MBU.

Bouncy was the first bouncer to ever try the Wall Bouncer Simulation and is the best one at it. He aspires to be the best bouncer ever from his generation, following his childhood's hero's footsteps.

He is friendly with everyone  and loves spending time at the Simulation.

Bouncy's antagonist and the main villain.

Some people say Wouncy hates Bouncy just for not being able to get better than him at the Wall Bouncer Simulation. If that's the case, then he definitely takes things way too far. He once trapped Bouncy inside a cave filled with traps and stole the elemental spirits to fight him.

He is really lonely, with his only companions being robots.

The main bouncer scientist.

This bouncer is a pure genius. He is the one who invented the Wall Bouncer Simulation and the one who chose Bouncy to be the first one to try it out. Nobody knows why he chose him, but it was definitely a good choice.

He loves spending time at the lab, experimenting and creating new things.

A triangle, that's for sure.

Not much is known about him, and he doesn't know much. He remembers entering a weird capsule during a war of some sort and ending inside a square room with some lights.
