User blog comment:South Kaioshin Daniel/Caribou and his brother Supernovas?/@comment-1781187-20110416211530

they arent as big a threat as the straw hats because the straw hats are powerful but caribou was known for ruthlessly killing marines. he's kinda the crazier, not as wanted, version of Kidd. Kidd killed as bunch of cilvilains which is why his bounty was 315 million. Caribou is the same becasue he basically did the same thing but with marines, not civilians
