When this card is Normal Summoned: You can Special Summon 1 "Super Defense Robot" monster or "Orbital 7" from your hand. Once per turn: You can target 1 "Super Defense Robot" monster or "Orbital 7" you control; it becomes Level 8 until the end of this turn. This card cannot be used as an Xyz Material for an Xyz Summon, except for the Xyz Summon of a Machine-Type monster.
