During damage calculation (in either player's turn), if your Defense Position monster battles an opponent's monster, and you have no Spell/Trap Cards in your Graveyard: You can discard this card, then target 1 "Superheavy Samurai" monster you control, except the battling monster; that battling monster you control gains DEF equal to the targeted monster's DEF, during that damage calculation only. When an opponent's monster declares a direct attack: You can banish this card from your Graveyard, then target 1 "Superheavy Samurai" monster in your Graveyard; Special Summon it.
