Yeah, I suppose I can just tell about both of my characters. I'll start with the good guy, and then the evil guy

Chopper: He eats anything with his Inhaling, and he lives in a Mushroom House on a planet called Clara (yeah, I know what you're thinking about the name). He is ten years old. He lives ALONE in the house, because his parents were killed by Maquano when he was four, and also Maquano blew up the planet he was born on. He hates Maquano more than any other character (they've been enemies for quite a long time). I first came up with him in uh... 2000? If you don't know what he looks like, this will show you (yes, I made the picture)

Maquano: He's obviously the main bad guy a lot of the time. He's 10,000 years old (or maybe older than that). He has killed many innocent people throughout his years. He never knew he was a demon, but he figured out he was once, and was in a human form in order to keep him from being chased by mobs of people (they try to get rid of all demons, but I'm sure Maquano would be able to KILL them all before they even try to attack him. They're just normal people). He has absolutely no heart at all, which is why he has been around for such a long time. He's destroyed many planets, including Chopper's birth planet, and nothing prevents him from blowing up planets. He has minions of course so they can do some of the evil work for him. He's got a sidekick named Camikon, who's the oldest Hellspawn around. He doesn't really care about him... I came up with this guy in 2008. Yep, that's when I thought of him. I have a picture of him if you want to see what he looks like (and it was also made by me)
