Demaro Black

Not to be confused with the real captain of the Straw Hat Pirates, Monkey D. Luffy

Monky D. Luffy is the Captain of the Imposter Straw Hat Pirates, appearing in chapter 598, 2 years after the War at Marineford.

Appearance
Monky D. Luffy appears to be a large and fat middle aged man, attempting to resemble Luffy with the trademark scar on his face, the Straw Hat and clothes. He also carries a Flintlock.

Personality
Monky D. Luffy is an extremely ruthless man, who disguises as Luffy and uses his name to spread fear around him, thus letting him to do as he pleases with seemingly no opposition. Due to this he is also very egotistical, and does not hesitate to shoot anyone in his way. He angers with ease, when things don't go as planned, as more than willing to gun down anybody who has made him feel any sort of unpleasant moment, so much that he shoots people who are just similar to the one he looks for, with apparently no qualm as he has been seen apologizing, albeit in a sarcastic manner. As he uses the name of Straw Hats to give himself great authority over pirates and normal people alike, one can assume he is also a coward and manipulator. He also has a unique laugh "Dohaha".

Powers and Abilities
So far he has been seen with a Flintlock, but so far he has shown no real proficency rather than just shooting those who are weaker than him. He seems to have some degree of great endurance, as he was capable of standing Nami's thunderbolts, and was still concious and walk without problems, albeit he was left in a very bad shape. His greatest ability is perhaps his manipulating skill, which he uses to trick everybody in that he's the real Luffy, so much that even pirates with bounties worth around 200 million Beli are willing to join him.
