• 2 Saibamen VS 2 othe fighters
• Charge your self-explosion power with Saibaman
• Explode near your opponent

Result:

• The opponent is dead
• The next fighter in the opponent team gets 9 bars of SP.

I think that's because I use changeHP(fighter1, -1000);  to make sure the suicidal fighter gets obliterated, and it adds 1000/4 to the opponent SP gauge.
