User blog comment:AYET/Canon death for Luffy/@comment-3986064-20140105170504

Luffy has chances of dying even in this arc, you saw how insanly powerful Law was, I must say that he is stronger than Luffy, overpowered is a fitting word for Law, but hell, Law himself was beat by Doflamingo... We even have an admiral that brought down an asteroid with his DF ability. You can say that Luffy has all those advantages, but he's still not such a monster.

I can easily imagine how Dofla could catch him in mid air and cut him in half while he can't dodge, unless he had actually learned geppou or a similar technique.
