Caribou is an interesting character who has been used by Oda very carefully in the story leading up to the final saga. Introduced in the story after the two-year timeskip, Caribou has had quite a lot of interactions with the Straw Hat Pirates on very interesting occasions. Having been introduced on Sabaody, he has gone on quite a lot of adventures in the New World ever since, and now, he appears to be finally on the cusp of his goal, which is, to join the Blackbeard Pirates and become a lackey of none other than the Yonko, Marshall D. Teach, also known as Blackbeard.
