2 Level 10 monsters
All monsters your opponent controls lose ATK equal to their DEF. When this card is destroyed (by battle or by card effect) and sent to the Graveyard: You can target 1 "Number 55: Burning Charioteer" or "Number 55: Gogogo Goliath" in your Graveyard; Special Summon the target, and attach this card to the target as an Xyz Material. If this card is Xyz Summoned by the effect of "Rank-Cross-Magic ZEXAL Fusion", this card gains the following effects for each of the following monsters attached to it as an Xyz Material.
● "Number 55: Burning Charioteer": Once per turn, during either player's turn, if a monster effect on the field is activated: You can detach 1 Xyz Material from this card; negate that monster's effects, and if you do, inflict damage to your opponent equal to its Level, Rank, Quality, or Wavelength, x 400. (If that target has a negative Level, treat it as having a positive one for this effect.)
● "Number 55: Gogogo Goliath": You can detach 1 Xyz Material from this card, then target 1 Level 4 EARTH and/or Rock-Type monster in your Graveyard; Special Summon that target, in face-up Defense Position, then if you have a Level 6 FIRE monster in your Graveyard, its Level becomes 6.
