Coribou

"Blood-Splatterer" Coribou is a pirate captain famous for killing marines who was at the Sabaody Archipelago around the time of the Straw Hat Pirates' reunion. He, along with his brother "Wet-Hair" Caribou, another infamous rookie, joined the Impostor Straw Hat Pirates. He has a bounty of 190,000,000, making him part of the new generation of rookies, following in the path of Luffy and the other Supernova over 100,000,000.

Appearance
Coribou is a very large, rotund, egg-shaped man, towering over his brother as well as the rest of their crew. His legs are rather skinny in comparison to the rest of his body. He has dark lips and circles around his eyes, and on his head is what appears to be an iguana that acts as his "hair", with the tail acting as a tuft, covering the right part of his face. He dons dark pants and shoes, and a lighter shirt with blood splattered on some parts near and on his neck (hence his nickname), with loose sleeves and ruffled edges, and what appears to be a Cross fleury, presumably the crew's jolly roger, on the chest.

Personality
Coribou appears to be rather dim to the location of things around him. Whether this is because he is foolish, or has bad eye sight is unknown He was facing the wrong way when answering his brother about smearing the plaza with a Marine's blood. He also seems pretty obedient to Caribou's requests, as he immediately started digging a grave to bury the Marine alive upon his brother's orders without question, showing no signs of compassion or mercy. He has a habit of calling Caribou "bro-bro." He is also always very nervous, and is constantly stuttering and sweating, which could suggest he is afraid of his brother.

Abilities and Powers
Coribou is a fearsome pirate captain who, along with his brother, managed to reach Sabaody Archipelago.

Weapons
He carries around a shovel, which he apparently uses to dig the graves of the people his brother considers "sinners" when asked to do so by Caribou, but it is unknown if he employs the tool as a weapon.

Past
Some time in the past, Coribou and Caribou became pirates and gained a fearsome reputation for killing Marines.

The Straw Hat Reunion
Eventually, the two brothers managed to reach Sabaody Archipelago, were they allied themselves with the Fake Straw Hat Pirates. They were first seen in GR 46, their allies' meeting point, together with some fellow pirate captains. After Caribou spotted and injured a Marine spying them, Coribou was ordered by his brother to bury the man alive, and he started digging with his shovel. The two were however interrupted by Fake Luffy, who ordered them to stop.
