Sentomaru, the sumo wrestler-like character in One Piece, used to give us nightmares during the popular Sabaody Archipelago arc. He could control the pacifistas and was undoubtedly one of the most powerful characters at that time. But now, the minor antagonist has turned into an ally of the Straw Hats as he needs to protect his savior, Vegapunk, from the wrath of the World Government. Thus, the emotional battle between Sentomaru and his uncle Kizaru left him in a devastated state in the series. So, is Sentomaru dead or alive? Find out whether the Egghead arc marks the end of the road for him in this post.

This post contains spoilers about the events of the Egghead arc in the anime and manga. We recommend reading the manga (up to the Chapter 1100) to avoid ruining the intended experience.
Sentomaru vs Kizaru in One Piece

The One Piece anime resumed the Egghead arc after a six-month hiatus and is currently adapting some of the best fights in this arc, starting with Sentomaru vs his uncle Kizaru.
As the bodyguard of Dr. Vegapunk, Sentomaru betrays the Marines and sides with the Straw Hat Pirates to help the old man escape from the island safely. Due to this action, Saturn, one of the ex-Five Elders, ordered Kizaru to take down Sentomaru and restore order at the futuristic island. The mentors going against their protege is a common theme in the Egghead arc as we earlier saw Garp take on Aokiji.
So, as we saw on Egghead island, Rob Lucci unleashed a strong attack on Sentomaru to make him go unconscious and took control of the Seraphim. In similar fashion, Kizaru crossed the labophase’s protection using his Pika Pika no Mi powers.
We knew Sentomaru had no chance against his uncle and, as expected, it didn’t take long for him to accept defeat. Even though Sentomaru tried to defend himself against his uncle, he was no match for him, and Kizaru defeated him swiftly by unleashing a laser beam attack.
After that, the admiral took control of the latest versions of Pacifistas. Once again, he was knocked unconscious, but Sentomaru certainly didn’t die after his fight with Kizaru.
Does Sentomaru Die in the Egghead Arc?

After going up against Rob Lucci and Kizaru, Sentomaru is gravely wounded at this point. Still, when Jewelry Bonney was falling from the Fabriophase, Sentomaru came at the right time to save her as they had became close friends when Kuma came with her to Egghead Island. Then, the One Piece Marine officers arrest him later on in the story.
It could have been the end of Sentomaru’s story, but Iron Giant Emet luckily unleashed Joy Boy‘s tremendous Conqueror’s Haki (read about types of Haki) throughout the island. This resulted in most of the Marines getting overwhelmed and fainting to the ground. The teary-eyed Sentomaru uses this opportunity to free himself and escape the island in a small boat. Thus, yes, Sentomaru survives at the end of the Egghead arc.
We might not see him around for a while, but he will be on Luffy and the Straw Hats’ side when the final war commences in One Piece. Until then, what do you think about Sentomaru’s character? Do share your thoughts in the comments below.
