Truthfully, for me battle mode Tsuna is not Tsuna but his twin brother or something because the way he acts is SO DAMN DIFFERENT! It's like if he is getting a split personality or something!
A no good Tsuna from beginning is still there with barely any changes. The battle mode is not him, it's a clone who is hiding in the tablet -_-
I dare you people to prove me wrong!
His future self is supposed to be all cool so I guess his clone finally took over
