Coribou

“Blood-Splatter Coribou” · alive · co-captain of the Caribou Pirates · first shown @0600

Etymology

Confidence: high · コリブー Koribū is the rhyming counterpart to his brother Caribou (Karibū / Koribū, both ending -bū) — a stock One Piece sibling-pair naming convention — sharing the caribou/reindeer theme that also gives their ship its reindeer figurehead. His self-applied nicknames stack the male-name suffix -助 -suke (‘help / assist’) onto unusual roots: 兄助 anisuke (ani ‘elder brother’ + -suke) and 神助 kamisuke (kami ‘god’ + -suke). Epithet “Blood-Splatter Coribou.” Source: One Piece Wiki — Coribou.

Arc-by-arc updates

Fish-Man Island — referenced (Ch. 650) — not shown

• Left aboard the Caribou ship when his brother boards the Sunny; cries “Big brother!!” and orders the crew to “give ‘em a nice greeting with the Gatling gun! Kill all the Straw Hats!” (pp.7-8) — only to realize Captain Caribou is already a hostage on the enemy ship.
