>>32237376No. Charizard was just that much stronger. It barely had an effect on him.
>>32237409That's just wrong, though. If you're going to use game logic, go all the way. By going by purely game rules, Charizard would only be hit by a Quick Attack, get 10% damage, and KO Pikachu that turn. It wouldn't get to move three times. Greninja's Cut and Aerial Ace would combined would get Charizard down to 30% HP max, and Charizard would KO Greninja with Flamethrower and Dragon Claw.
If you're going to go by game rules, go all the way. And this is assuming they were the same level, which wasn't the case, but even if we assume they were, Zard comes out on top.
