10 One Piece Devil Fruits Everyone Thinks Are Weak — The Hidden Powerhouses You’re Overlooking

One Piece is full of powers that look silly on the surface and terrifying once someone clever gets ahold of them. A lot of the most deceptively strong ones sit in the Paramecia bucket, where creativity matters as much as raw strength. Here are ten Devil Fruits that seem gimmicky at first glance but can absolutely tilt a fight if you know what you are doing.

1. Noro Noro no Mi (Slow-Slow Fruit) - Paramecia
   User: Foxy the Silver Fox
   The deal: It fires slow beams that temporarily put targets in literal slow motion. Sounds goofy until you realize freezing an opponent's movement for even a few seconds is a golden window to land guaranteed hits. Foxy demonstrated it during the Davy Back Fight, repeatedly stalling opponents and tagging shots they would normally dodge.

2. Hobi Hobi no Mi (Hobby-Hobby Fruit) - Paramecia
   User: Sugar (Donquixote Pirates, Trebol Army)
   The deal: Touch someone, turn them into a toy, and wipe every memory of them from everyone else. It is bizarre, but it is also horrifyingly effective crowd control. Sugar turned whole squads into toys in Dressrosa, effectively removing threats from the board without a single actual injury.

3. Horo Horo no Mi (Hollow-Hollow Fruit) - Paramecia
   User: Perona (former commander of Thriller Bark's Wild Zombies and Surprise Zombies)
   The deal: Ghosts. Not cute ones either. Perona's hollows induce crushing negativity and despair, mentally folding opponents before a punch is thrown. The Straw Hats found that out the hard way on Thriller Bark when most of them went emotionally down for the count.

4. Suke Suke no Mi (Clear-Clear Fruit) - Paramecia
   Users: formerly Absalom; currently Shiryu of the Rain
   The deal: Invisibility for the user and anything they touch. Observation Haki can usually track an invisible foe, but in practice, perfect awareness is rare. Case in point: Shiryu slipped through the chaos and stabbed Garp mid-fight, which is exactly the kind of ugly, fight-ending surprise this fruit exists for.

5. Baku Baku no Mi (Munch-Munch Fruit) - Paramecia
   User: Wapol (king of the Evil Black Drum Kingdom)
   The deal: Eat anything. Merge what you eat with your body or mash different things together into new tools and forms. It sounds like a gag until you remember it is basically on-the-fly weapon crafting and body modding. Wapol mostly squandered it, but the Drum Island arc showed flashes of how versatile and dangerous it can be.

6. Ton Ton no Mi (Ton-Ton Fruit) - Paramecia
   User: Machvise (Donquixote Pirates, Diamante Army)
   The deal: Crank your body weight up by literal metric tonnes and turn yourself into a wrecking ball. Simple? Sure. Effective? Oh yes. Machvise demonstrated in Dressrosa that a well-timed tonnage drop can break bones, even on giant-sized opponents like Hajrudin.

7. Bara Bara no Mi (Chop-Chop Fruit) - Paramecia
   User: Buggy the Clown (yes, that Buggy; also yes, Emperor Buggy)
   The deal: Split your body into pieces, control and levitate the parts, and become immune to slashing attacks. It reads defensive, but that immunity alone nullifies a massive chunk of One Piece's deadliest cuts, and Buggy has used the separation gimmick for plenty of tricky surprise hits. If this fruit ever awakens, the clown could get way scarier.

8. Yomi Yomi no Mi (Revive-Revive Fruit) - Paramecia
   User: Brook (Straw Hat Pirates musician)
   The deal: You die once, then your soul returns and you come back. That second life supercharges the soul, unlocking a toolbox of spirit tricks: leaving his body at will, wielding the chill of the underworld, and more. Brook has turned that into real combat strength and cemented himself as one of the crew's stronger fighters.

9. Kiro Kiro no Mi (Kilo-Kilo Fruit) - Paramecia
   User: Miss Valentine (former Baroque Works officer agent)
   The deal: Change your weight from 1 kilogram to 10,000 kilograms. Go feather-light to float or mountain-heavy to pancake someone. Back in the pre-timeskip era, Miss Valentine used it in Whiskey Peak to bounce between mobility and power in a way that still holds up as one of the smarter early-game fruits.

10. Mane Mane no Mi (Clone-Clone Fruit) - Paramecia
    User: Mr. 2 Bon Clay
    The deal: Touch someone once and you can copy their face and voice perfectly. On paper it is just cosplay; in practice it is chaos. Bon Clay weaponized impersonation to infiltrate, confuse, and generally break enemy lines, and he has used it more than once to pull off clutch saves for Luffy and the crew. Hugely underrated.

If you think any of these read like joke powers, that is the point: a lot of One Piece is about turning the weird into an advantage. In the right hands, these fruits are nasty.

One Piece is currently available to watch on Crunchyroll.
