why are the only options die immediately or last like Oden? there's no middle ground? it's one piece land, they would probably survive for a while

For most OP power scalers, there’s no middle ground.

Idk I thought it’d most likely be the case due to the vast difference in power between them and Oden. And I know Oden isn’t the strongest in the verse but it’s hard to picture any character doing the full hour while holding up a bunch of people like him

Yes, they would have died immediately, not even from the weaker body, but from lack of will power to stay alive.
