Can You Guess?

My ten favorite characters (it was pretty hard to narrow it down...)

A genius billionaire playboy philanthropist, a goth ghost hunter, a Z-movie loving robot, an alien supervillainhero, an angel who did not so much fall as saunter vaguely downwards, an American ninja, the meat and sarcasm guy, the most dangerous dragon in Berk, a lonely and romantic trash compactor, and a different athlete.

Do you know who they are?
