Top Ten Overpowered Broken Devil Fruits in One Piece

1. Hobi Hobi No Mi (English Name: Hobby-Hobby Fruit; User: Sugar; Type: Paramecia). On one touch, Sugar will turn you into a toy, enslave you, and have the world forget your existence. And it works on anything that has a mind, from insects to giants. It is an insanely stupidly powerful ability that should have no place in the series but somehow got through. Hopefully, we never see something of its likeness again.

2. Ope Ope No Mi (English Name: Op-Op Fruit; User: Trafalgar D Water Law; Type: Paramecia). The name even says it's OP. Law can do really ridiculous things inside the sphere he conjures: teleport, swap things around (even personalities!), cut people without killing them, cut anything (even seastone!). He can even bestow immortality to someone by giving his own life.

3. Horo Horo No Mi (English Name: Hollow-Hollow Fruit; User: Perona; Type: Paramecia). Perona can make all your hard training useless by making you succumb to nihilism by having you pass through by the invincible ghosts she produces. She can make countless of them and can make them explode. She also uses them for scouting. She can also do an "out of body experience" ghost, much like what Brook is doing now.

4. Mero Mero No Mi (English Name: Love-Love Fruit; User: Boa Hancock; Type: Paramecia). Allows user to turn to stone anyone captivated by her. And it turns out that literally everyone (even animals, girls, okamas, and den-den mushis) is attracted to Hancock in the One Piece universe. Well, except Monkey D. Luffy.

5. Nikyu Nikyu No Mi (English Name: Paw-Paw Fruit; User: Bartholomew Kuma; Type: Paramecia). Pretty harmless name for a devil fruit, as it turns out that it gives the user the ability to repel anything! Kuma uses it to blink across the battlefield and fire-off air pressure cannons. He even makes bomb of compressed air. It has one of the best utilities by giving anyone a free transportation to any destination. He can even repel non-physical stuff like fatigue out of the human body.

6. Kage Kage No Mi (English Name: Shadow-Shadow Fruit; User: Gecko Moriah; Type: Paramecia). Moriah can steal people's shadows, and those poor guys can never go outside on a sunny day again or they will disintegrate. He will put these shadows to dead bodies to give them life again, and he has complete control over them. He can even unleash his own shadow to fight. And this thing is indestructible, can separate to small pieces, can shape-shift to anything, and can float. He can also instantly swap places with his shadow. Finally, he can call all the shadows he stolen from their current hosts to integrate to him and boost his physical power.

7. Soru Soru No Mi (English Name: Soul-Soul Fruit; User: Charlotte "Big Mom" Linlin; Type: Paramecia). It is just introduced and we haven't seen all its capabilities yet, but it's already proving to be similar but more troublesome than the Kage Kage No Mi. As Big Mom can get the lifespan of any humanoid and put it on anything that isn't humanoid to give it life. She even weaponized a ball-of-fire and thunder cloud with this to give illusion of controlling the weather.

8. Goro Goro No Mi (English Name: Rumble-Rumble Fruit; User: Enel; Type: Logia). Enel could have been one of the most dangerous beings in the story if only he isn't introduced early and his power is completely nullified by the main character's. Besides his obvious destructive power and invincibility, he has abilities to listen to radio waves, travel long distances in a blink, restart his own heart, and reshape metals.

9. Yami Yami No Mi (English Name: Dark-Dark Fruit; User: Gecko Moriah; Type: Logia). Blackbeard can cause anything to be swallowed by his "darkness". Still a power not fully explored, but it has the ability to absorb devil fruit abilities, handicapping almost every top-tier fighters. He can swallow a whole town and regurgitate it as piles of rubbles. He can absorb anything that comes in his way, however, if he fails to defend, then he experiences more pain than normal.

10. Gasu Gasu No Mi (English Name: Gas-Gas Fruit; User: Caesar Clown; Type: Logia). Caesar can experiment with all kinds of gas and integrate it to his being, making all parts of him deadly. He's also invincible as a logia, Despite lacking instant destructive capability. He uses his gas powers creatively to do super-explosions and incinerating blasts. He can catch off-guard even the strongest of foes by suffocating them and they won't notice, as he has the ability to manipulate the air around him.
