Kabuto and Minato mid diff.
Kabuto would've absolutely spanked Itachi if he weren't edo and had Sasuke with him. And SM Minato is going to be all over the place in this battle. Itachi will have to keep Susano'o up constantly to even stay alive in this fight, which we all know he isn't capable of doing unless he's edo. and Nagato can hold his own, but for how long. Especially without CT.
