He Was in O'hara and Defected to the Navy at the Beginning!

Jellal traveled to the world of One Piece, ate the mysterious "animal type, phantom beast species, horse fruit, and unicorn form" Devil Fruit, and activated the strongest talent system, becoming the youngest major general in the history of the navy! However, power also breeds Jellal's ambition to subvert the entire world. So he rescued Olvia's mother and daughter on O'Hara Island, declared to defect to the navy, and fought against Akainu and Aokiji with high-end combat power at the level of an admiral... Sengoku: "Jelal's Red Devil Pirates are very powerful, far more terrifying than the Rocks Pirates back then! If our navy encounters Jellal, we can complete the mission and return home on our own." Whitebeard: "The strongest man in the world should be Jellal. This guy's fruit power is already so terrifying before he awakens. If he fully awakens, he will have the power to destroy the world with one blow!" Five Old Stars: "Jeral's thoughts are very dangerous. To our world government, he is the most vicious criminal in history who is a greater threat than the dragon!" Robin: "He is my lifelong nightmare. I love and hate that man..."
