Tarnished Trowel's body is made of an absurdly durable material, which can withstand and outlast any punishment that Tarnished Battler throws at him. Moreover, Tarnished Trowel is completely immune to any status effects, and has jagged spikes gruesomely jutting from his body that can gruesomely pierce anyone who dares try to strike him. Tarnished Trowel has a unique win condition to remain standing, no matter what. On the other hand, Tarnished Battler has monstrous strength and durability but is still relatively swift. Although Tarnished Battler's cells are highly unstable, granting him limited regeneration and his body parts can transform into weaker but plentiful versions of him known as Tumored Battlers, Tarnished Trowel's durability and immunity make him a tough opponent to defeat. So, the winner of the battle is You.
