Television series
One Piece
A rubber-limbed pirate captain assembles a crew of oddballs and sails toward a treasure that's really an excuse to explore an enormous, cheerfully absurd world. It swings wildly between slapstick comedy and gut-punch tragedy, often within the same episode, and asks a serious time investment — over a thousand episodes and counting — in exchange for one of anime's most rewarding long-form emotional arcs.

Naruto2002
If Luffy's dream of freedom got you, Naruto's dream of being seen and respected will too — same shonen engine, same patient decade-long commitment, same payoff when the underdog finally lands the punch that matters.
But The filler episodes are legendary, and the emotional beats can feel manipulative if you're allergic to earnest speeches about willpower.

My Hero Academia2016
A tighter, more modern shonen with the same big heart: a kid with no power inherits a legacy, builds a ragtag crew of classmates, and grows into someone worth rooting for.
But The power system gets complicated fast, and later arcs lean harder into grim stakes than the sunny start promises.

Fullmetal Alchemist: Brotherhood2009
Same scale of ambition — a sprawling world, a huge cast, a quest that turns out to be about something bigger than the prize — but told with tighter plotting and a genuinely devastating ending.
But It's darker and more melancholy throughout; the humor is there but doesn't dominate the way it does in One Piece.

The wildcard
Something you would not have found on your own.
Cowboy Bebop1998
Both follow a small crew of outsiders bound together by circumstance, moving from episodic adventure to episodic adventure while a bigger emotional story quietly accumulates underneath — Bebop just plays it as tragedy instead of comedy.
Same premise stripped to its bones — a crew of misfits drifting between episodic jobs while a larger story simmers underneath — but jazz-scored, adult, and aching with a melancholy One Piece only shows in flashes.
But It's twenty-six episodes of slow-burn mood over plot, and the ending refuses the triumphant payoff you're trained to expect.

Hunter x Hunter2011
The Chimera Ant arc alone proves this show can out-think and out-devastate almost anything in the genre; if you love One Piece's world-building, this rewards you with even stranger, smarter systems.
But It's been on hiatus for years due to the creator's health, and the pacing is even slower to start than One Piece's.

Dragon Ball Z1989no page yet
The grandfather of the genre — the training arcs, the escalating power, the sheer joy of a fight that takes three episodes — is all here, decades before One Piece refined it.
But It's dated in its animation and pacing, and the power-up-and-scream formula gets repetitive fast.
Bleach2004
Another Shonen Jump giant with the same crew-of-misfits structure, but swap the sea for the afterlife — sword fights, soul society politics, and a hero who starts as an ordinary teenager.
But The middle stretch drags badly, and the anime's pacing issues are notorious even among fans.

Demon Slayer2019
Gorgeous, modern animation and a tighter runtime make this the easiest on-ramp back into shonen if One Piece's length intimidates you — same warmth, same tragedy, half the commitment.
But It's much shorter and more linear — you lose the sprawling, decades-long world One Piece is famous for.

Attack on Titan2013
A completely different register — grim, political, relentless — but the same instinct for turning a simple premise into an enormous, meticulously built world worth getting lost in.
But There's none of One Piece's humor or warmth; this is bleak, violent, and emotionally exhausting by design.

Fairy Tail2009no page yet
The closest thing to One Piece's guild-as-family warmth outside One Piece itself — loud, funny, sentimental, with a crew you'll want to spend a hundred episodes with.
But It's widely seen as the weaker cousin — less inventive plotting, more repetitive power escalations.
Porco Rosso1992
Both are about outlaws who chose the sky or sea over society, building loyal crews and living by their own code — Porco Rosso just compresses that whole feeling into a single wistful film.
Miyazaki's tale of a bounty-hunting seaplane pilot has the same love of freedom, the same crew of oddballs, and the same bittersweet undercurrent beneath the adventure — in two hours instead of a thousand episodes.
But It's quiet and adult where One Piece is loud and young — there's no big fight, just a man, his plane, and his regrets.

Captain Blood1935
One Piece's DNA runs straight back to golden-age pirate adventure films like this one — the noble outlaw captain, the ragtag loyal crew, freedom on the high seas as the ultimate prize.
This swashbuckler basically invented the template — the charismatic captain, the loyal crew, the fight against tyranny at sea — decades before Oda ever picked up a pen.
But It's black-and-white, theatrical, and dated in its politics and pacing; this is pure classic Hollywood, not modern spectacle.
