Of the 19 original (non DLC characters), 18 of them have instant kill finisher moves in Persona 4 Arena Ultimax. Only non-shadows, minus Shadow Labrys (not to be confused with Labrys in Shadow Form), can use the instant kill finishers. SHO Minazuki is the only non-shadow character to NOT have a instant kill finisher yet Sho MINAZUKI does have one (not confusing at all right).
Instant kill finishers can only be done when you have 100 SP and are winning the fight. They are performed by pressing down three time followed by Y+B or Triangle+Circle. Only Shadow Labrys’ is performed differently and it is down three times followed by X+A or Square+X twice right after one another.
Enjoy!
