One Piecehas always been a story about found family, loyalty, and embracing inner weirdness, and that is why the Straw Hat crew is so beloved. Luffy’s ragtag gang is filled with oddballs, misfits, and people chasing impossible dreams. They do not just fight strong enemies; they live boldly, love deeply, and support each other no matter how wild the journey gets.
But what if other anime characters could hop aboard the Thousand Sunny?Some anime heroes, even from totally different worlds, would actually fit in surprisingly well with the Straw Hat vibe.Whether they are reckless, kind-hearted, dream-driven, or just a bit unhinged, these eight characters have what it takes to be honorary members of Luffy’s pirate crew.
Inosuke Hashibira might not know what a boat is, or be able to swim, but that would not stop him from hurling himself into the Grand Line with nothing but raw instinct and sheer bravado. The wild boar boy would thrive in a world where strength talks and every day is a new life-or-death adventure. His battle-hungry nature fits right in.
But more than just muscles and madness, Inosuke has that underestimated emotional core that defines so many Straw Hats. Beneath the brashness is someone desperate for belonging, something Luffy would immediately pick up on.Fans ofOne Piececan picture him bickering with Zoro, racing Sanji for food, and throwing tantrums until Nami punches him into the ocean.A perfect fit.
Yuji Itadori already lives by a code that mirrors Luffy’s, and that is to protect his friends, stay true to his beliefs, and die before betraying someone who trusts him. With his mix of kindness, fearlessness, and supernatural strength,Yuji would slide easily into the chaotic energy of the Straw Hats.He is earnest, adaptable, and never backs down from a righteous cause.
Plus,Yuji’s cursed energy abilities would be a wild new additionto the crew’s power set. Fans ofOne Piececan just imagine the havoc he and Luffy could cause in a tag-team fight. His deep sense of compassion would also mesh well with the likes of Chopper and Robin, while his love of food makes him an obvious Sanji favorite. He would feel like family in no time to the Straw Hat crew.
Himmel may be a more traditional hero, but that is exactly why he would make such an interesting Straw Hat. His charm lies in his quiet leadership and unwavering desire to make people’s lives better, not for glory, but out of pure kindness. That same spirit defines Luffy’s brand of leadership, and the Straw Hats would absolutely respect Himmel’s nobility and warmth.
Himmel’s swordsmanship and compassion would remind Zoro of his own path, and he would bring a gentle maturity that balances the crew’s louder personalities.
Despite being from a more grounded fantasy world,Himmel’s swordsmanship and compassion would remind Zoro of his own path, and he would bring a gentle maturity that balances the crew’s louder personalities. Himmel does not need to prove himself, and that calm presence would make him a rock-solid anchor among the emotional chaos that is life on the Sunny.
At first glance, Caiman feels too grimy and chaotic to fit in with the Straw Hats, but scratch beneath the surface, and he is exactly their type. He has got a cursed reptile head, no memory of who he is, and an unkillable drive to find the truth. That kind of wild backstory practically screamsOne Piecematerial.
Caiman’s loyalty to his friends, especially Nikaido, mirrors the crew’s unshakable bonds.His resilience, goofball humor, and brute-force approach to problem-solving would make him a hit in a world where absurdity reigns supreme. Fans ofOne Piececan almost hear Franky calling him “Super Lizard-Bro!” as they build weapons in the kitchen. He would fit right in with the insanity.
Pokemon
Ash Ketchum might not know how to fight a sea monster without Pikachu, but fans know this eternally 10-year-old explorer would be thrilled to cross the Grand Line. He has already a wanderer with a boundless appetite for discovery and friendship. That sense of wonder and optimism would blend seamlessly with the Straw Hats’ adventurous spirit.
His natural leadership skills and refusal to give up on anyone would resonate with Luffy, and his bond with Pikachu would be an adorable new element on the Sunny.Ash brings heart, enthusiasm, and a kind of innocent determination that would remind the crew why they started sailing in the first place.Plus, Usopp would 100% try to catch a Pikachu of his own.

From Avatar: The Last Airbender by Nickelodeon Animation Studio; Created by Michael Dante DiMartino and Bryan Konietzko
Technically not an anime by Japanese standards, but if any anime fan is being real, Aang would make an incredible Straw Hat. As the Avatar, he is powerful, spiritual, and goofy, which are all qualities the crew already embraces.Aang’s playful nature, deep compassion, and refusal to kill even in the face of war would set him apart as both comic relief and moral compass.
Aang has got the perfect blend of fun and philosophy to thrive in a world of talking reindeer and floating islands.
Imagine Aang and Luffy airbending and gum-gum-punching their way through the Marines, or Zoro training with him to better understand energy flow. Even Robin would respect Aang’s connection to history and the past. Aang has got the perfect blend of fun and philosophy to thrive in a world of talking reindeer and floating islands.
Naruto Uzumaki’s journey from outcast to herois basicallyOne Piecewith ninjas instead of pirates. His resilience, loud optimism, and deep need for acknowledgment mirror Luffy’s own growth. The only thing louder than Luffy’s laugh is Naruto’s entrance, and together, they would form the most chaotic, inspiring duo on the high seas.
Naruto’s jutsu, shadow clones, and battle strategy would be a massive boost to the crew’s strength.But more importantly, Naruto understands loneliness and loyalty in a way that would bond him instantly with the Straw Hats.He would be a brother to Luffy, a rival to Zoro, and an endless ramen-slayer alongside Sanji. Just do not let him steer the ship.
Edward and Alphonse Elric are a two-for-one deal the Straw Hats would never pass up.Edward’s firecracker personality and Alphonse’s gentle soul would slot neatly into the crew’s dynamic.Their quest to restore their bodies is the kind of all-or-nothing mission Luffy would risk everything to help with, and they would do the same for him.
Their alchemy would revolutionize the Thousand Sunny, with Ed likely collaborating with Franky to create absurd new gadgets. Meanwhile, Alphonse and Chopper would bond over being “non-human” with the biggest hearts on deck. These two already have the courage, trauma, and humor that define a Straw Hat, so all they need now is a Jolly Roger of their own.
