Well, I found one that is very easy to do. When your oponent is against the wall, it works best:
small jump in with HP
standing HP
forward LP
body punching combo (half circle forward HP)
while doing this (hit the punches more for more hits), call out Shingo
at the end, Shingo will trip up the oponent and hold them
While he's holding, repeat the first three steps, and end the forward LP with a Super Special (two punch buttons and the ultra combo where the screen goes weird).
This should kill the bastards!
