This thread is bound to start a flame war, it is highly unlikely that Sasuke would fight the four Hokage, such an act is against the principle/purpose of them being revived.
The Kage's reaction if Sasuke tried to fight them: :rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl:
lol your sig says "jman rapes little boys" yet your avi is the guy that can be quoted as saying "i want your body sasuke" "all i need is that little body of yours sasuke"
If kishi gives him a power up like he gave Naruto with BM, then they could use the kages to showcase how strong Sasuke is. Sasuke could beat them and that could build him up as a huge threat against Naruto.
