Ever wanted to see Fox fight Falco Dragon Ball Z style? I know I have! These two videos are "Tool Assisted Speedruns", meaning they used emulators and special tricks to perform moves perfectly, there are no human players that can do these things, though in theory it would be possible. I'm pretty sure these are also the Project M versions of Fox and Falco, not original Brawl. Nevertheless, impressive! Don't blink, you'll miss the good part!
PS, there's one other video with Fox, Falco, and Wolf.
