Cripes. I haven't even been able to defeat Master Core on Smash Bros.' harder difficulties at all yet, so watching this Ganondorf defeat a level 9 Master Core without taking any damage is baffling.
Seriously, スマブラチャンネル is a beast for pulling this off.
Level 9 intensity, for those that don't know, is the highest difficulty level in Smash Bros. single player mode. You have the option not to battle this particular boss at that difficulty, presumably because it's too challenging for most players. Not this one though!
Thanks for the tip, Alex.
