Vegapunk's Betrayal He led every fan to believe that the traitor was one of the satellites when the real traitor was hiding in plain sight. Towards the end of the chapter, Shaka made it clear that the actual traitor was none other than Dr. Vegapunk himself.
This character has betrayed the straw hats unexpectedly. Vegapunk is one of the main characters in the Egghead Island arc of One Piece. He is a character full of intrigue that Oda built up carefully from before the timeskip.
While One Piece has many superb side characters, Big News Morgans just proved why he is the best of them by betraying Luffy and his crew. This may not seem like an action that would endear Morgans to One Piece's fans, but his reasons for doing this give him a delightful layer of complexity.
Though Kinemon was successful in defeating Kanjuro, the end of the chapter proves that the War for Wano is anything but predictable, as Kaido descends upon the grieving samurai.
He was punished for the sins of Orochi's grandfather and he paid a great price. Having lost all sense of being, Kanjuro began working for Orochi and infiltrated Oden's Samurai only to betray everyone at the last moment. Kanjuro is certainly an incredibly evil person.
Like Orochi, the persecution of his family had made Kanjuro a twisted man with a similarly demented disposition, however, he lacked the perverse sense of revenge against the people of Wano that Orochi enforced under his rule, and instead is apathetic.
He is among the nicest characters in the One Piece series. However, his "betrayal" wasn't for his sake, but rather his entire crew. Sanji felt that he had no choice in the matter, since they would be in grave danger otherwise.
The overarching antagonist groups of the saga are the Beasts Pirates and the Big Mom Pirates. Wano Country Arc: Kaidou and the Beasts Pirates, Kurozumi Orochi and his forces, Big Mom and the Big Mom Pirates. CP0 and briefly, Marine Admiral Ryokugyu as secondary antagonists.
Blackbeard is the greatest pirate rival of Luffy. He'll certainly be the final obstacle of Luffy.
Every Straw Hat Pirate is, without a doubt, loyal to their captain, and they will offer their lives for him in a heartbeat. Of course, fans can be certain that Luffy will definitely do the same. That said, there is one crew member who stands above the rest in terms of loyalty to Luffy: Roronoa Zoro.
When Luffy first faced Crocodile, he was unprepared and weak. Crocodile drained Luffy of moisture with his sand powers and left him for dead in quicksand. If not for Nico Robin returning to question why Luffy continued to fight, Luffy would have died underneath the dunes with no one to find him.
Nico Robin
She stayed with the crew until after the events of the Water Seven arc, when she was found out by the CP-9 and coerced to turn herself in to help the World Government read the Poneglyphs. She initially refused, but agreed to leave after the CP-9 threatened to launch a Buster Call against the Straw Hats.
She told Buggy that she had betrayed her captain. In exchange for her freedom, she handed over Luffy. Luffy was then imprisoned and even almost blasted by Buggy's strongest cannon. In addition to that, she explicitly told Luffy that their relationship was purely for business.
Robin also seems to be very devoted to Luffy, as he is the only person whom she wants to get stronger for. This shows how great her dedication to her captain has become after being rescued from Enies Lobby. Upon learning of Ace's death, Robin was very shocked and became greatly concerned about Luffy's wellbeing.
1 Nami Was Sanji's First Love
He became enthralled by her charms seconds after seeing her in the Baratie and has remained so ever since. The chef goes above and beyond for her sake, whether preparing special meals or obliging requests that he ordinarily wouldn't.
In the latest episode of the series, it's revealed that the favor Pudding asked Sanji for was actually a kiss. But she used her Devil Fruit ability to remove the kiss from his memory, leaving her the only one truly heartbroken from his returning to the Straw Hats.
No. However an explanation is in order. Zoro will never betray Luffy for four reasons. Without Luffy Zoro would have met an early death at the hands of the Marines.
1) Blackbeard
With the power of both the Dark-Dark and Tremor-Tremor Fruits, Blackbeard is most likely still above Luffy's level.
Nami was one of the first characters to join the Straw Hat Pirates, and remains an extremely important character to the story. When it comes to strength, she's the weakest member of the crew, which is why she often relies on clever tricks and strategies in battle.
Orochi did not show fear towards Kyoshiro and attempts to kill him with his allies, but the latter and his team sliced his Yamata no Orochi heads off leaving him to deal with Kaido. When Orochi attempts to kill Hiyori, Denjiro killed Orochi by slicing his head off and protected Hiyori.
8 Kanjuro's Devil Fruit
This Devil Fruit belongs to the Paramecia class and it allows him to produce ink and draw using it. What's special about this is that whatever Kanjuro draws can be controlled by him as if it had life. Kanjuro is very good at drawing and even cloned himself quite fast, as seen in Wano.
Kaido is the main antagonist of the Wano arc. He took over the Land of Wano several decades ago and ruled it with Orochi. Kaido values strength above anything and he's always looking for a good fight.
