Niseluffy

Niseluffy is a character from the game Set Sail Pirate Crew!. He's a Monkey D. Luffy impersonator and minor antagonist.

Appearance
Niseluffy bears an uncanny resemblance to Luffy, although with slightly different clothing (like a white shirt behind his vest). This allows him to successfully impersonate the Straw Hat Captain.

Personality
Unlike the real Monkey D. Luffy, Niseluffy is shifty and cowardly, preferring to let his subordinates fight for him and fleeing away when confronted by Yuta's crew alone.

Abilities and Powers
Niseluffy wields a whip resembling Luffy's stretched arm, which he uses for combat. He's no match to the real Luffy, however.

Trivia

 * The concept of a Monkey D. Luffy impersonator would be realized in the actual story through Demaro Black of the Fake Straw Hat Crew, introduced during the Return to Sabaody Arc, ten years after Set Sail Pirate Crew!.
