Maybe Kaido's son is actually stupid. He might be dumb, but strong.
I think he's just calling him an idiot because he's not there.
What makes me curious is why you need the Flying Six to take up this challenge.

- Is he super fast/agile?
- Is he just a big dumb brute who's practically immovable?
- Is he secretly the next strawhat?
HMMMMMMMMMMM
