Super Smash Bros. is a fighting game as only Nintendo could make one, emphasizing cute characters bouncing off each other in front of colorful backgrounds. It’s all safe and fun, like anvils falling on cartoon characters’ heads.

So leave it to a fan like YouTuber Sterling to take the “realism” up a notch with some bone-crunching shots borrowed from Mortal Kombat, forcing you to picture—in great detail—the organ failure and worse harms that Mario, Link and the rest of Nintendo’s cast must be suffering as they wail on each other.

The only way it could be better (and even more disturbing) is if it somehow worked in the original Smash Bros. N64 commercial as well. You can have that one for free, Sterling.
