This monster can only be Special Summoned by Fusion Summon (from the Extra Deck). Once per turn, you can remove 1 "Elemental Hero" monster in your Graveyard from play to have this card gain ATK equal to the level of the removed monster x100. If this card attacks, your opponent cannot activate any Spell or Trap Cards until the end of the Damage Step. When this card destroys a monster by battle and sends it to the Graveyard, inflict damage to your opponent equal to the ATK or DEF of the destroyed monster, whichever is higher.
