4 Level 5 LIGHT monsters
If this face-up card would be destroyed, you can detach 2 Xyz Materials from this card instead. When the last Xyz Material(s) is detached from this card: Inflict 1500 damage to your opponent. If this card has "Number 102: Star Seraph Sentry" as an Xyz Material, it gains this effect.
Once per turn: You can detach 1 Xyz Material from this card, then target 1 face-up monster your opponent controls; change that target's ATK to 0, and if you do, negate its effects.
