What makes a good LF2 Character?

[LutiChris]

I don't know if this has been discussed before but i was hoping it would serve as a good reference for people who are looking how to perfect their character's and make them 10/10 so everyone will absolutely love to play them over and over. Just comment bellow and list a bunch of things that you would personally like to see in a character. No specific moves or attacks. Just generalized things that would make character performance/artwork/data/sound/whatever most enjoyable for your entertainment.
