Kelly Funk is a skilled boxer from the Kingdom of Mogaro, with extremely violent behavior. However, his stamina is very low and can be defeated easily with one blow. Quite the opposite of his brother Bobby Funk, who is strong but extremely peaceful, to the extent that he will not use his colossal strength against an opponent. To compensate for each one's weaknesses, Kelly has eaten the "Jake Jake no Mi", which allows him to transform in a kind of jacket, with which he can control whoever wears it. Thus, Kelly becomes Bobby's jacket, combining the two in a devastating fighter.
