You remebered me something, in the Marineford war, Luffy vs Mihawk, the moment Luffy could see the image of his own arms being cut by Mihawk if he did attack that time. Link to that page

The idea it portraits is good enough to explain why Doffy is alive eventough he is a Paramecia user if he really is, without taking into account any theory we said before in this blog.

Which means Doffy has to dodge next week before his head is being cut for real.

I'm not sure if it's a capacity derivated from kenbonshoku no haki.
