Itachi by S.Nara: teh spammer
Barbatos Goetia by Kurogane: exibit b, the steriod user Itachi is powerful and spams wayyy too much (at least this version) and Goetia... he has a "penetrate"/super armor that lasts at the min 20 hits long you're probably going to need a cheap character to even hope to stand up to these two.
Both should be with in the database, I'm pretty sure I saw them. if not, they're links are the first to appear in google when typing in the name an creator. I'll see if I can put them on some file sharing site if anyone has any trouble
