There are many conversions of that one succubus from that one Capcom fighting game; heck, even I made one a long time ago.  So rather than throw yet another one onto the pile (besides, there's already a versus-style Lilith anyway), I decided to try my hand at a different Lilith instead.  Namely the one from Vanguard Princess, whose claims to be the daughter of Satan may be disputable but her rasslin' skills are definitely undeniable.  You know what to expect by now: non-MvC character with UMvC3 gameplay, X-factor, and marvelous combos that with her you can even start from throws if you're skilled enough.
