I want Killer B wins but I can't support it so I'm going with Minato.

He can mid diff killer bee even in his base form

Base minato is a way more balanced match up

Stomp

Pretty sure B has no sealing anyway.

Minato Claps, Stomps, Crushes, Slaps.

Slaps, smash, claps, smacks

Stomppp

Base Jonin Minato was already shown fully capable of defeating Killer B + the Fourth Raikage ☠️
