oh boy im going to have a field day with you lol.
for starters anything by wlanxmania,zobbes, beanfan12, terrible cartoon chars who are coded like shit
google mugen naruto and most of them suck if they aren't by alexei,myself sort of or vector,
most Kingdom hearts chars suck horribly theres a few decent ones but most are crap
anything by IMT unless its wolvenom or cray/sabaki had a hand in its creation.
alot of the old cvg creations are pretty shitty they are now known as creator cast.
anything by axkingsrevenge is crap nice sprites but crap coding
most sonic chars are crap not all but definitely most
is that a good start? ill have more for you later lol.
