Umm, the GxV suggests Goku and Vegeta.
Hahaha, darn. I didn't see that. I knew it was Goku and Vegeta, but I was enjoying the fact that since the entire cast wore those boots at one point it could've been anyone.
In fact, for all I know, it could've been Yamcha hi-fiving Krillin.
EDIT: STUPID SEXY GANONDORF. Why is he hugging a plus-sized Lucca from CT in that one pic, though?
