I gotta say, Shanks wank is always a little hard to believe. There's too much telling and not enough showing. We're told he stopped Kaido, but it's hard to imagine. Him stopping Akainu at Marineford looked kinda bland, like how is that block anything special? There's always this aura of Shanks being so badass but we never actually see follow-through. Even the CoC knockout is just "intimidation". Where's the force to back it up? He looks like a normal dude minus an arm.
