For this AI video I show off an easy way to clear The Showdown with no stock loss, via some extensive AI exploitation.
The strat is simple, stay on one side of the stage, and spam Blaster while Mewtwo and Ganondorf bust their shields and Giga Bowser eats it all as he shambles over. As they get near, jump up and away, then Fire Fox through Giga Bowser, run over to the other side of the stage and repeat. In the meantime, look for opportunities to up smash/uair Giga Bowser. Once Giga Bowser is dead, you can just spam Blaster on Mewtwo and Ganondorf all day as long they're far away enough, as they'll just stand there and break their shields over and over. Once enough damage is racked, just go up to them after a shield break and up smash.
I'll go through this with Fox without using a blatant AI exploitation method, but I thought I would show this off.
