My Q and a really simple one at that is: How would Gai get past Raikages raiton armor? If that thing is infused with lighting and Raikage is by default fast How does Gai think we is going to land a punch without being electrocuted?
I also think that Raikage have similar weights than what lee used in the Chunnin exam, As far as I can remember He still had those weights on while fighting Sasuke. Although I merely speculate about the weights. I do think they serve a purpose, now just Imagen how fast he must be if he already moves faster than what Sasukes vision allowed him to see while casting Ameterasu with the weights on!!!! So I first need to find a way on how Guy would even get past Raikages defense needless to say he still need to penetrate Raikages brute force aswell. And one thing you all forgot, he is the Raikage, that means something.
