you should look up the SVC (SNK Vs. Capcom) characters since they're styled to match the KOF formula and art style. not to mention there's a section for characters that have been converted to the KOF/SNK style (usualy a 4 or 5 button format).
and yes, there IS a crap load of Kula Diamond and Athena Asamiya edits. Yes, some of them are worth your time.
hell, there's a crap load of edits for just about EVERY character!
just do yourself a favor and don't pass up the CVS (Capcom Vs. SNK) Characters. yes, they are different from the SVC characters, as they are two separate games made by the opposing dev teams.
