Electromorphosis

Electromorphosis causes the Pokemon to become Charged whenever it takes damage from any move. The Charged status doubles the power of the Pokemon's next Electric-type move, functioning identically to the move Charge's offensive component.

The Charge effect persists until the Pokemon uses an Electric-type move, at which point it is consumed. Taking additional hits while already Charged does not stack the effect. The ability triggers from any damaging move, regardless of type or whether it makes contact, giving it broad activation conditions.

Electromorphosis is the signature ability of Bellibolt, the Electric-type Pokemon introduced in Generation IX. Since Bellibolt has respectable bulk, it can often survive hits to take advantage of the Charge boost. Combined with powerful Electric STAB moves like Thunderbolt or Parabolic Charge, a boosted attack after taking damage can deal significant damage to opponents expecting Bellibolt to be purely defensive.
