Usopp bears a remarkable resemblance to Usopp, with minor differences in clothing. However, because Niseusopp is a fish-man, he has blue-ish skin, gills, webbed hands, and sharp teeth. His nose is long and pointy, somewhat resembling Usopp's own nose. This allows him to successfully impersonate the Straw Hat Pirate's sniper.
Niseusopp is rather cocky and arrogant, but not through a false bravado that is expected of the real Usopp.
Abilities and PowersEdit
Niseusopp is a fish-man, so he was presumably born with ten times the strength of a regular human.
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. Niseusopp, alongside Niseluffy and Nisezoro were stationated at a local bar, keeping an innocent young woman as their hostage and servant. Niseusopp then confronts Luffy and his allies when the latter intrude in their turf.
Once Niseluffy gets beaten by the real Luffy, Nisezoro threatens the life of their hostage to keep the Straw Hat captain at bay, giving Niseusopp an opening to trap Luffy into a Seastone cage. The real Roronoa Zoro then shows up and battles Nisezoro, defeating the latter and then Niseusopp himself.
After Niseusopp and Nisezoro's defeats, Nezumi arrives at the scene and arrests the impostors.
- Usopp would eventually get his own canon impostor in the form of Mounblutain of the Fake Straw Hat Crew during the Return to Sabaody Arc, although in Mounblutain's case, he was attempting to impersonate Usopp's alter-ego Sogeking instead of Usopp directly.
