These heroes are either an opposite of a normally friendly career, or even of race, or even appearance, or are true promisers in a sense, or are surprising despite whatever harmless or silly sounding name they process alone. The common themes for this type of hero are angels, fairies, light beings, Santas, elves, clowns, puppets, and toys. Things that are supposed to represent innocence and friendship donning a controversial theme then what is expected of them.
NOTE: Do not add Demons to this list as they no longer contradict what they are meant to be. Also, such characters must take on this form/guise for the majority of the work they are in, and not for a short time.
