Robbon

Robbon may look like a cute bunny person, but he's actually a mass of black slime. In a metal endoskeleton. In a fursuit which is also his skin. In a suit. He often walks with a cane because of how heavy his endoskeleton is, but he is capable of walking and running without it. Other dream creatures commonly mistake him for a sweet dream or daydream, but he's a full on nightmare. Sometimes he tries to use this misconception to his advantage, but mostly it just annoys him, and he'll somewhat often pick fights with those who don't believe him. Capearthown has temporarily banned him from actually scaring dreamers after a certain incident which resulted in mass heart attacks in the waking world. Robbon spends a lot of time fighting in the arena and hanging out with Angzend. Sometimes he brings Angzend to team-up matches. Being a slime monster, nothing really hurts him. He can make the sky appear dark red within a certain area around him. He can be a bit sadistic at times, but has a soft spot for weaker dream creatures, and will more of just try to scare them instead of outright harming them.

He lives in some kind of airship. It started off as a balloon back when he was basically a plushy and slowly upgraded it and himself over time. A few stray dream and nightmare creatures have moved in, most without his permission, but he likes to keep them around for entertainment purposes. He's actually made friends with most of them.
