Just whipped these up. Original sprite made with Famitsu Character Generator (http://www.famitsu.com/freegame/tool/chibi/index1.html).

From left to right: Ulcerite; Csytling; Deadite. I'll probably update these and fill in the other five, but don't hold your breath.
Feel free to modify these at your will, credit would be nice but not necessary, please and give any and all constructive criticism,
Rex.
WOW! These are awesome! Thanks for sharing.. :)
