A Mamoswine. He made it past that trainer's Kabutops and Volcarona before he went down, so I'd argue he still put up one heck of a fight.

Plus, that match dragged on forever. My Scizor against his Mamoswine, both healing, hail storms on and off... It really could've gone either way.

[He doesn't consider a loss as a sign of poor training. Even the elites have to lose sometimes.]
