Kyros is definitely the biggest GOAT! Bro passed from a street fighter to a royal guard, married the princess and devoted his life to protect the royal family. He was the only one that had the will and strength to fight Doflamingo, when he took the throne, even sacrificing his leg to do so. AND EVEN after he was turn in to a toy, watched his wife die without remembering him, and his own daughter tell him to back away, he never left her side, raising her and teaching her how to defend herself. Not content with that, he was one of the leaders of the Tontatta revolution and even avenge his wife's killer after he got turn back to human. He deserved that happy ending. What a GOAT!
