One Piece's Devil Fruits grant the consumer special supernatural powers. The protagonist Luffy, for example, has a very rubbery body as a result of eating the Gomu Gomu no Mi Devil Fruit. Luffy encounters many fellow Devil Fruit users throughout the series, from antagonist Marshall D. Teach to allies like Tony Tony Chopper.
However, fans agree that there are some incredibly odd powers that the Devil Fruits bestow on others after consuming them. From the ability to turn people into toys to shapeshifting into extinct animals, many of these powers, though useful, would be strange and pretty terrifying to have in real life.
10 Eating Any Of The Ancient Zoan Fruits Grants The Ability To Turn Into An Extinct Animal
All Zoan Devil Fruits give their consumers animal characteristics or the ability to shapeshift into a different animal. However, eating the Ancient Zoan Devil Fruits specifically give the eater the ability to transform into an already-extinct animal — dinosaurs included.
For example, X Drake ate an Ancient Zoan Devil Fruit that gave him the ability to turn into a fearsome Allosaurus. Those who eat Ancient Zoan Devil Fruits also might gain bodily characteristics commonly found among present-day animals, giving the consumer an edge in combat.
9 Karasu's Devil Fruit Can Turn Him Into A Murder Of Crows
Karasu's Devil Fruit ability gives him the ability to turn into an entire murder of crows. It is never canonically stated what specific Devil Fruit Karasu ate to gain this ability, but many fans assume that it's a Zoan type, considering that he turns into an animal form.
This is a unique Devil Fruit since it made the user turn into a group of animals rather than a singular one, like most other Zoan types. However, fans agree that this would be a fairly awesome power that'd either confuse or terrify foes who weren't expecting a flock of animals to appear.
8 The Wielder Of The Kage Kage No Mi Can Steal Shadows — Literally
If one eats the Kage Kage no Mi Devil Fruit, they can steal other people's literal shadows. They can also transfer these shadows into other people's bodies, thus potentially creating zombies. This terrifying yet strange power is one that most fans wouldn't want to end up with if they ever ate a Devil Fruit, mainly because it could mean the start of a literal zombie apocalypse if things got out of control. However, the results of using it were awesome to watch throughout the series itself.
7 Eating The Ope Ope No Mi Bestows The Power Of Spatial Manipulation
Eating the Ope Ope no Mi Devil Fruit means that the user can create a spherical "room" where they have control over the placement and orientation of anything. A doctor used its abilities to help with completing surgeries, which many viewers thought was a cool way to deploy such powers.
However, it can also be used for more deadly purposes in a battle to destroy enemies, making this ability both useful and intimidating. Fans believe that if the power was in the right person's hands, it could do a lot of good for people, as demonstrated by the doctor who once wielded it.
6 The Consumer Of The Mane Mane No Mi Can Copy Others
When eating the Mane Mane no Mi Devil Fruit, the user can touch another person and transform into a doppelganger version of them. This odd ability can be great if the user is trying to perhaps protect another person by confusing foes with a double of their target.
This skill also proves useful if the user needs to run away and pretend to be someone else for a short while, especially if their own life was at stake.
5 The Gura Gura No Mi Could Potentially Destroy The World
Eating the Gura Gura no Mi Devil Fruit enables the consumer to create vibrations or quakes. The twist villain Marshall D. Teach consumed this particular Devil Fruit, reputed to be powerful enough to destroy the world. Fans have mixed feelings about this power; some think it'd be awesome to have the power to literally shake the earth, while others note its obviously destructive effects.
4 The Soru Soru No Mi Gives The Ability To Manipulate Human Souls
Fans were awed when they found out that eating the Soru Soru no Mi Devil Fruit meant that the user could interact with — and manipulate — other human souls. Some fans immediately decided this would be a creepy power to have, considering that it meant interacting with likely-dead people. However, others thought this would be the perfect way to become a shinigami if they wanted to, considering that this power specifically deals with human souls.
3 The Toki Toki No Mi Allows Its Consumer To Travel Through Time
The Toki Toki No Mi Devil Fruit allows its consumer to time travel forward into the future. Fans thought this was a pretty unusual power, but also very cool for seeing new eras or escaping trouble in a current one.
Fans agree that this would be a useful Devil Fruit to eat if they wanted to go forward in time and see what the future would be like. However, others think that going into an entirely new time period would end badly and adjusting to the change would be difficult. Even worse: the user can never go back to the past they came from.
2 Sugar Can Turn People Into Toys After Eating The Hobi Hobi No Mi
After eating the Hobi Hobo no Mi, Sugar gained the ability to turn people into toys and erase their existences from other people's memories. Additionally, this Devil Fruit's power has the secondary side effect of granting the consumer eternal youth.
Fans consider this power to be one of the silliest in the series. Other fans are terrified of being erased from their friends and families' existences after being transformed into a toy themselves. However, both sides agree that the side effect of eternal youth after eating this fruit would be awesome to have.
1 The Hana Hana No Mi Is The Perfect Way To Cause Some Body Horror
Eating the Hana Hana no Mi Devil Fruit enables its consumer to replicate and sprout pieces of their body from the surface of any object or living thing. Nico Robin consumed this particular Devil Fruit, and the many odd ways she uses its power in combat freaked out many fans, especially those who weren't fond of body horror in general. Though some fans agree it could be useful despite how terrifying it is, it's a very strange power and not something most people would enjoy wielding.
