One of Rigel Runeslayer's various heroic adversaries who want to overthrow his rule. Kosmo Skyshadow is your typical, stereotypical hero. You know the type; the plucky, young upstart who's kicked off into the universe. Rigel can't help but pity the blonde rabbit; it's almost unfair if you really think about it. He never stood a chance; every victory Kosmo gains in his quest to save the universe was truly just Rigel toying with him.
