5 Strongest Non-Canon Villains in One Piece




“Black Arm” Zephyr, was the leader of the Neo Marines and the main antagonist of One Piece Film: Z. He was once a Marine admiral and instructor before his resignation.
Alongside Garp, Sengoku, and Tsuru, Z was one of the most powerful Marines of his generation. Despite his old age, Zephyr had tremendous physical prowess.
He mastered Busoshoku Haki at the age of 34, allowing him to coat himself with it and turn his arms black for much more devastating strikes and defenses, which earned him the nickname “Black Arm”.
He was able go toe to toe with Admiral Kizaru several times, and later showed extraordinary stamina by stalling Kizaru, several vice admirals and an entire battalion by himself — all without the Battle Smasher — before ultimately dying in the battle.


Byrnndi World is the captain of the World Pirates and the main antagonist of the 3D2Y anime special.
World is a very powerful pirate, as he was held in Level 6 of Impel Down and escaped, which was thought to be near impossible. He had a 500,000,000 Berries bounty, which testifies how large of a threat World was according to the World Government. Despite his age, he remains a world-class threat.
World ate the Moa Moa no Mi, a Paramecia-class Devil Fruit that allows him to increase the speed and size of objects. He typically uses this to increase the size and velocity of projectiles, increasing damage, as well as boosting his own already powerful speed to higher levels.
He is very skilled in using Busoshoku Haki.
