>>9029327Ogremon.
While I do really like a lot of things about him, I have no real idea why he's my favorite over the gross guys, giant bug monsters, and super robots. Any time I even try to think "Maybe Ogremon isn't my favorite" whatever I come up with doesn't feel right. I guess I just really like the idea of an Greenskin dude being just another thing fighting in a world that has cool robots and the devil.
Mikemon is a close second solely because I have a pet calico cat.
