1) Kinemon is the only who most took over the will of Oden, not Momo, not Luffy, not Zoro. He also has ryuou unlike Zoro and others, he also just honestly have a similar personality of chaotic moron.
2) Lol if you think rayleigh was on Roger, WB, and Garp's level. Noland is a legend too, when you get to the new world, even top commanders of yonkou are top like 15 characters in the world of one piece, which has billions of people in it, so yeah, a pirate king's first mate would absolutely be considered legendary, even if they get one hit by roger/whitebeard. I don't care if brainlets think rayleigh is frieza level, he's still nowhere near yonkou leveled even in his prime, let alone prime whitebeard/roger level when all were in their prime. Rayleigh was fighting Oden and Streusen in their primes, people like Whitebeard, SHiki, etc would no diff him easier than Roger no diff'd Oden.
3) Hawkins wont' become Law's second mate. Bepo is going to become Law's captain clearly, and Zoro is going to become Hawkins chore boy. (if we're just making shit up to shit on the characters we are talking about)
Hawkins will be one of the strongest pirates of luffy's generation, so will Law, Kid, Crocodile, etc.
