I recently had an idea that may become a new work. The main cast being animals, but right now I think I may need some help.

I need some animals for the characters to be, the more you can think of the better:

Good: any heroic, loyal, peaceful, beautiful or cute, pretty much anything that works for a goo guy.

Bad: mean, vicious, frightening, or plain ugly.

This way I'll get a good idea of how both sides will look.
