Mounblutain

Far bigger and broader than the genuine Sogeking, Mounblutain is an enormous man. His mask copies the original but is enlarged and overdone, leaving part of his face exposed where the true one would cover it, with a long fake nose and horns that come off straighter and rounder than the wavy, flat originals. He sports striped trousers, a dark red cape echoing Sogeking's, a plain shirt, brown boots, and a yellow sash knotted as a belt. Large curly hair and a heavy beard complete the disguise, and once unmasked his true face shows wide features, thick lips, a flattened nose, and rounded teeth.

A near-constant grin or laugh marks Mounblutain's demeanor. Like his fellow frauds, he leaned on the Straw Hats' fame to cow others, but the exposure of the ruse revealed him as a coward who pleaded with Caribou for mercy. He showed an unexpected streak of honor, becoming the only impostor to strike at Caribou in a bid to rescue Drip, the false Sanji, even knowing his foe was a Super Rookie carrying a 210,000,000 berry bounty.

Mounblutain possesses a measure of toughness, staying on his feet after being hit by carnivorous plants and a huge lightning strike, though battered in the process. He has some muscle too, hoisting Chocolat after a faint and lifting a heavy bazooka with little effort. His will, however, is feeble; Luffy's Supreme King Haki dropped him instantly. As a weapon he wielded a flintlock pistol and later a bazooka, but his aim fell well short of a true sniper's, missing targets even at close range.

Masquerading as the Straw Hats, his crew tried to recruit followers in a Sabaody bar until the real Usopp and Nami struck them with carnivorous plants and lightning. The fakes pressed on hunting the pair until they collided with the actual Luffy, whose Supreme King Haki knocked them out. Regrouping, they gathered recruits at Grove 46, only for the Marines to surround them and for Sentomaru to expose their leader Demalo Black as a fraud. Mounblutain and the others fled but froze when the genuine Luffy appeared, then fell into the hands of Caribou and Coribou. As Caribou throttled Drip with his Devil Fruit, Mounblutain fired a bazooka that passed through the Logia user harmlessly, and Caribou's men beat him down. His fate afterward is left unknown.
