Literally walking right next to him.
If Croc ever gets legit Haki, he will be such a fucking problem.
But my GOD is his Haki ass.
Really hoping Crocodile gets CoC based on this:
Crocodile is one of the smartest fighters in the series, IMO.
I think Luffy really lit a fire under his ass, Croc realized his Haki weakness, and he's been training it.
