>>18594081Mewtwo was wild, so no EVs, it was level 70 (which I didn't count, or else it would have KO'd), and Charizard might have been even higher leveled, also in the special Mewtwo didn't mega evolve. And even if it used Mega Punch it would have been a 3HKO, and considering the fact that it was weakened by his other attacks like Fire Blast and Swift, it would have been enough to put it at a low HP ammount to catch it.
