What makes a good LF2 Character?

[Rhino.Freak]

the only thing I say is that the character should have combo's, if he's comboable, he's fun.
make basic moves that are combo's like deep's D>j etc.
sprite effects should be there, like wind moving wherever it suits etc.
also sounds are more important that you think, having awesome effect sounds will boost the fun by 10 times!!
