Blyue is seen wielding a horseman's axe, usually used when he is in his giant form. He also wields a shield that he uses for attacking rather than defending.
Round the Land
Blyue was in the pirate crew of Dorry and Brogy, but their ship sunk 100 years ago in a heavy storm. He believed that Brogy and Dorry had drowned, as they ironically thought the same fate of him. Blyue survived, however, and was washed ashore on the "Vacation Island for Pirates".
He felt insulted by his comrades and desired to be a pirate again. When he heard of the Legend of the Blue, being that one can fulfill one's wishes thereby, he had an idea. He would open a hotel and send pirates on a treasure search. He did not make any customers for 100 years, though, until Luffy and his crew showed up. Blyue then took Vivi prisoner and provoked them, forcing the Straw Hats to battle all their old foes and clear his resort's arc-themed challenges. He fought Luffy after Vivi escaped. Blyue lost, but fulfilled his desire nonetheless.
The Blue finally shattered. When Luffy told him that Brogy and Dorry were still alive, he was glad and realized that his friends were still alive, apologizing to Luffy afterward. He told Luffy that he would also become a pirate again someday. He wanted to look for a crew as great as Luffy's.
Blyue is the first giant known to have consumed a Devil Fruit in the franchise, but is not the first canon giant Devil Fruit-user.
As the Mini Mini no Mi had been consumed by Lily Enstomach, it can be inferred that Blyue has died, or that he could never have existed in the anime.
