Dude, when I beat Emerald, he never hit me. And I wasn't even level 99. Link Knights of the Round to HP Restore. Then W-summon it, Mime, Mime, Mime ect... Yeah it takes forever to kill him, but you own him easily. By my calculations he has around 1,000,000 HP. Then again, I'm the only person I know who has ever had Air Tam Storm MISS. So....
