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 man, taller than his brother. He is also very fat with a large stomach. He has skinny legs in comparison to the rest of his body. He has what appears to be an iguana that acts as his "hair". In his first appearance he was seen carrying a shovel. On his shirt is what appears to be a Cross fleury

Personality
Coribou appears to be rather oblivious to the location of things around him. He was facing the wrong way when answering his brother about smearing the plaza with a Marine's blood. He also seems pretty obedient as he immediately started digging a grave to bury the Marine alive upon his brother's orders without question.

Abilities and Powers
His true abilities have yet to be shown. However, as a pirate captain, he has command over the other crew members. It can also be assumed that he is fairly strong since he was able to make it to Sabaody Archipelago.
