One Piece was a very popular Japanese manga and anime. It depicted a world full of pirates and adventures, where each character had different Devil's Fruit abilities and special skills. The Demon Fruit was a mysterious fruit that could grant the consumer various abilities and attributes. For example, Luffy's rubber fruit could turn him into a huge tropical animal, and Sauron's sword fruit could turn him into a huge panda. The Devil's Fruit ability user can obtain a unique ability by eating the Devil's Fruit. Some ability users could use their own abilities to attack, such as Luffy's rubber fruit, which could rub their bodies and produce powerful attack power, while others could use their own abilities to defend or assist in attacks, such as Sauron's sword fruit, which could turn him into a huge panda, which could protect him from attacks and display powerful attack power. Other than the Devil Fruit ability users, there were many other characters in One Piece who also had various abilities and skills. For example, many characters in the navy had all kinds of high-tech equipment and combat skills, while the four emperors and other high-level pirates had great strength and combat skills.
