Abilities and Powers[]
Caribou is a pirate captain reputed as a fearsome killer of Marines, who has managed to reach Sabaody Archipelago, sailing through the first half of the Grand Line. In his first appearance, he was able to detect the presence of a Marine hiding nearby who was spying on the recruits and reporting their presence to his superiors. However, contrary to this, he later failed to notice Franky was right next to his hiding spot, looking at him.
While the impostor Straw Hats saw Caribou to be a valuable asset and a terrible force to get on the wrong side of due to his fearsome reputation and abilities, none of the real Straw Hat Pirates even see him as a threat, but instead as nothing more than an annoyance. Franky stated that the reason why Caribou is no threat is due to him being an idiot. Indeed, despite his Logia-class abilities, Luffy easily sent him flying out of Ryugu Palace and knocked him unconscious with one punch, showing that Caribou has low endurance, compared to Luffy's strength. He was also easily defeated with a single punch from Pekoms, who went on to claim that Caribou was overconfident just because he is a Logia-class user, which is what led to his defeat.
Speed[]
Caribou even though he is a Logia user he had shown to have above average speed, during his battle with Pekom. During the first parts of the battle, Caribou was able to dodge several of his blows and managed to get in a few quick blows himself. During his only fight with Smoker and some of the other Marines, Caribou moved very quickly and thus he was able to get them into his swamp trap, thus they had lost.
Strength[]
Caribou had shown to have greater strength than the average man, he had managed to carry a giant scythe to use against Pekom. He was easily able to move this scythe across the battle field and thus he was able to combat Pekom, until he had turned in a tortoise form and thus Caribou couldn't break through the shell.
Agility[]
Caribou has shown to have great agility as well, he was able to quickly dodge several of Pekom's blows before he was defeated by him. He is light on his feet, so Caribou has appeared to be more of a pirate of speed than strength whenever it comes to a combat situation.
Weapons[]
He used some sort of spear or polearm to stab the Marine who was spying at the Fake Straw Hats meeting point. He was also seen wielding a flintlock pistol. During his battle with Pekoms in Fishman Island, he used a Gatling gun and a scythe, hiding them within the infinite space of his swamp body.
Devil Fruit[]
Main Article-Numa Numa no Mi
Caribou ate the Numa Numa no Mi, a Logia-class Devil Fruit which allows him to become and control a swamp or bog like substance. He can create swamps of various size, either in his hand, such as the one he used to drown Drip, or a giant one as he did to capture a trio of mermaids. He can also use this ability to absorb any form of an attack using the swamp mass. It seems that people who step on his swamp mass can sink in it, even if its outer appearance looks shallow, similar to Blackbeard's Yami Yami no Mi. It also seems that people who sank into his swamp and were absorbed filled his stomach and satisfied his hunger; this acts as some form of storage space. Caribou claimed that the swamps he can produce are bottomless, thus giving him the power to store virtually everything inside his body.
The real Sanji was able to kick him despite his Logia intangibility, but it was shown later on that he was deliberately hiding his power so the crew will drop their guard, as he does not believe he can take them all alone; normally, Caribou can shift into his intangible swamp element to allow attacks to be harmlessly absorbed. A major weakness of this fruit is that, if he is in his Logia form, he is confined to his volume, as seen when Franky locked him up in a barrel and he was unable to escape. He also has the standard Devil Fruit weaknesses and he is vulnerable to Haki attacks.
