This card cannot be targeted by your opponent's Spell/Trap effects. Once per turn, when an opponent's card or effect is activated: This card becomes unaffected by effects of that card type (Monster, Spell, Trap, etc.) until the End Phase. Once per turn, during either player's turn: You can detach 1 Xyz Material from this card, then target 1 "Number" monster in either Graveyard; equip it to this card, but banish it when it leaves the field. While equipped with a monster(s) this way, this card's ATK becomes the sum of the numbers in the names of all "Number" monsters equipped to it this way x 100. If this card is destroyed by battle or a monster effect: You can Special Summon this card from your Graveyard and attach all other cards (min. 1) you control to this card as Xyz Materials, then destroy the monster that destroyed it, and if you do, inflict damage to your opponent equal to its ATK on the field. You can only use this effect of "Number 100: Boundless Dragon Apeiros" once per turn. When an attack is declared involving this card and a face-up "Number 1: Terminal Sorcerer Miden" your opponent controls: All player's LP become 0.
