Buggy holds a bitter grudge against Red-Haired Shanks over the matter of his Devil Fruit curse. In their youth, both men were pirates aboard the same ship, the Oro Jackson which belonged to Gold Roger and his crew the Jolly Roger Pirates. When they were not fighting, the pair constantly argued over everything imaginable (in the flashback in the manga and the anime alike, they argue over whether the North or South Pole is colder). Despite the difference between them, both pirates stayed together for some strange reason while they were on board the ship. This led Whitebeard to to notice and even remember seeing a "big nose" with Shanks during their battles with Gold Roger
