A variation on unstable energy- you accumulate energy in your body due to damage. The more energy that builds up, the bigger the resultant explosion! The buildup of energy is represented visually by sparks around the character, so you can tell when they're in danger of exploding.
Buildup Effect:An effect that gets played on the character as they build up energy.
Explosion Power:The actual power used to release energy.
