I'm more confused on what his actual hype is. His intro makes it clear it's the fact he's UNKILLABLE that grants him his status, nothing about nobody being able to harm him, he already had the big visible scar from Oden and the fact he's been captured several times before which directly implies he's been hurt on several occasions.
But from the Luffy fight, you truly got the impression he can not be hurt period unless you have an extremely high skill set, and that his raw durability is his best asset. Which is now false as he's getting dog walked by characters weaker than Luffy, so go figure. What does he even have left to offer ?
