@taichokage: That's not beating. That's tieing out. L-Sama is Omnipotent.
@5th said: That's a joke, either of the two wouldn't last a second against SSJ Goku but still a good fight
It wasn't meant to be canon, it was just a fun project they worked on together for the lols and it was pretty damn funny and entertaining, even keeping all the cast members in character. We know Goku would beat them all easy, but in a cross-universe that may bring their base down to about equal status, it would fit rather well. And fighting for Food is definitely something that Goku, Toriko and Luffy would go for. So it was a perfect fit.
