4 Level 5 monsters
When this card destroys an opponent's monster by battle and sends it to the Graveyard: Inflict damage to your opponent equal to half the destroyed monster's original ATK. If this card has "Number 105: Battlin' Boxer Star Cestus" as an Xyz Material, it gains this effect.
Once per turn: You can detach 1 Xyz Material from this card, then target 1 monster your opponent controls; destroy it, and if you do, inflict damage to your opponent equal to the destroyed monster's ATK on the field.
