Masamune-Maki by Untruthful Dragon
My first approch at a null character, hes an edit of R-Masamune by YANMAR.
His 12p is the palette which has all the null codings, he can kill many characters
such as G-Guanyin-ICE, Guanyin-MAKI, Salvation Donald, Crazy Catastrophe and more from p2 side.
P1 side is a bit weaker, but can still kill many characters.
