Super Smash REX 0½ Casual Gameplay - Mega Mewtwo Y

Just like Mega Charizard X, he's meant to be purposefully overpowered in some aspects. If you mash the A button 20 times while charging Shadow Ball, he'll do a huge Kamehameha-esque blast that does a ton of damage. I'll admit I kind of got carried away and tried to do this a lot more than I should've and ended up leaving myself open to being attacked. Download REX here: https://www.rexbuild.site/
