When and unstoppable force meats an immovable object.
Saitama from one punch basically one-hit KO’s EVERYONE. In contrast, Wobbuffet has one of the highest HP and Defense stats in Pokemon, and with the move “counter” can deal double the damage an opponent deals to it. You could argue that Saitama would still be able to one-hit KO a wobbuffet…BUT! If wobbuffet had an in game item called the “focus sash” it allows any pokemon to survive a potential KO with 1 hp left. Meaning probable complete destruction of earth, if “counter” is used against Saitama.
Shout out to my best buddy Alex for giving me this idea to work off of.
