My choice all of them what might happen if you have that retarded banana is this
Sonic is just going to take all the damn credit because he is so fast
Picachu will screw everything up he might shock the Mario to death
Mario: get in the damn poke-ball Pikachu
Pikachu: No i dont want to
Master Chief is gonna run off and start killing everyone and if he kills Peach I don't think Mario has enough coins for all that funeral crap.
And the last one is pretty damn obvious.
