    In the world of pirates, while others are still developing small skills of Devil Fruit, our protagonist has already played with the Thunder Fruit and directly developed it to the level of destruction! Other ability users will release a small thunderbolt, and when the protagonist takes action, it will be a "thunder", directly electrocuting the enemy to a crisp on the outside and tender on the inside. The hair can be styled into the most fashionable "Afro", as if it is holding a bird's nest. Every time the enemy sees the protagonist raising his hand, he will be scared to death and shout: "No, stop the electric shock, why don't I surrender? I don't want to become a grilled fish!" The protagonist looked proud: "It's too late, today is the end of your thunder!" In this way, the protagonist relies on the invincible ability to develop the thunder fruit, walking sideways in the pirate world.
