Monkey D. Luffy
Someone else (elaborate in post)
And it can't be inborn quality if the fruit itself is artificially made. It means anything could have been put in there, along with dragon transformation and special ability of flight.
And I don't see why Oda would make distorted Luffy's face have same shades and same blood veins Doflamingo has.
What you go to prove the contrary ? Nothing obviously, so you can fantasize as much as you want, but since you got nothing to prove your claims with, I'll just smile at posts like these, cheer yo
In this chapter (699) there are two panel in which Momo watces Dofla's picture. Tho, he doesn't say anything, he looks scared. But nothing for sure there. I wonder if Oda was not trolling us again with that hallucination. Like with the hamburger in Vergo's cheek.
Its definitely Dofla, though we Oda hasn't reveal the purpose of that panel yet. My guess is that Momo gained a unique ability from his Fruit but he hasn't realize or able to control it yet. Considering that both Kinemon & Momo are following the SH's to Dressrosa, I do believe that it will happen to Momo again and maybe then we might know what it really is/.
