During the Damage Step, when your FIRE monster battles an opponent’s monster (Quick Effect): You can send this card from your hand to the GY; until the end of this turn, that opponent’s monster loses 500 ATK/DEF, also its effects are negated. If your FIRE Warrior monster destroys an opponent’s monster by battle, while this card is in your GY: You can Special Summon this card, and if you do, it gains ATK equal to that destroyed monster’s original ATK, until the end of this turn. You can only use 1 “Matoran Legend Lhii” effect per turn, and only once that turn.
