Niseluffy bears an uncanny resemblance to Luffy, although with slightly different clothing (like a white shirt behind his Doskoi Panda brand vest). This allows him to successfully impersonate the Straw Hat Pirate's captain.
Abilities and PowersEdit
Niseluffy wields a whip resembling Luffy's stretched arm, which he uses for combat. He is no match for the real Luffy as he is left barely standing after taking one of Luffy's attacks.
After reuniting with the real Luffy later, Yuta and his crew sail to Orange Town, where they learn about the presence of the fake Straw Hats from Boodle. Niseluffy and his subordinates were stationed at a local bar, keeping an innocent young woman as their hostage and servant. Niseluffy and his subordinates then confront Luffy and the Gejitsu Pirates, with Luffy managing to beat his impostor.
Once Nisezoro and Niseusopp are defeated, Nezumi arrives at the scene and arrests the impostors. However, he ends up arresting the real Luffy (who was trapped in a Seastone cage) instead of Niseluffy. Yuta and his crew soon realize this, causing Niseluffy to jump into the ocean and quickly swim away in panic.
- 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!.
