Out of all the characters in One Piece, Oda nerfed Kyros the most. Not only did he have him cut his own leg off, but then turned him into a toy for 10 years. So with 10 years out of practice with fighting, and on one leg, he was able to defeat a man whose devil fruit made him the worst possible opponent for a man with one leg, and the entire time Kyros was standing on fluttering ground, he was also protecting his daughter at the same time, and still won. Without being 10 years out of practice, and if he had two legs he'd be Top Tier easily as that would put him at 44 years old, which is typical Prime age range for a lot of characters.
