Happy

Happy, the magical cat with a unique ability to fly and carry just one passenger, is a cherished member of the Fairy Tail guild. Despite his powers remaining largely mysterious, he quickly befriends Natsu and Lucy, forming a tight-knit trio. Known for his upbeat personality and unflappable optimism even in dangerous situations, Happy serves as a mediator between his fellow guild members, particularly Natsu and Gray. His ability to fly at incredible speeds makes him an invaluable asset, the only transportation option that doesn't discomfit Natsu.
