The Stress Flame is the (probably unofficial) name for the flame that occurs when a character's Stress Meter reaches its peak. This blue flame (later purple) bursts forth from around the angered character, surrounding them and providing a moment of invincibility. A hapless opponent who happens to be too close or attacking at the time the stress flame comes out will take a small amount of damage and be sent flying back. Opponents can also be KO'd by this flame.
