Besides Haki, Devil Fruits are the main energy system in One piece. Fans have seen dozens of Devil Fruit powers over the years, and the vast majority of these powers are part of One piece'is the official canon. That said, there are a fair amount of non-canon Devil Fruits also. Most of these non-canon Devil Fruits are forgettable, but there are a few that would be welcomed into canon with open arms.

Most of the Non-canon Devil Fruit that should be canon can be seen in One piece movies or specials, but several only appear in anime filler arcs. There are three categories of Devil Fruit, but the best non-canon powers belong to the Paramecia class. As a result, users possess a variety of superhuman abilities.

10 Lucky fruit can steal other people's luck

Majority One piece Fans would agree that Luffy and the Straw Hats benefit from a lot of luck, and the Luck-Luck Fruit could change that drastically if it were canon. If the user successfully touches someone, they can steal that person's luck. By doing so, the user becomes extremely lucky – while their target is forced to be extremely unlucky.

In certain situations, the user becomes invincible due to the luck they have stolen. The target who has lost their luck will have to deal with unfortunate occurrences immediately. The user can only keep the stolen luck for a short period of time and cannot control what that luck is used for. If it were canon, the Lucky Fruit would be very useful, but more importantly, the concept of bad luck and wasting good luck by mistake on silly things would be fun.

9 The comeback fruit can reverse the aging process

The Neo Marines are a splinter faction that wants to annihilate all pirates in the New World, and they have some Devil Fruit powers – including the Return-Return Fruit. This Devil Fruit is similar to the Rewind Quirk in My Hero Academia, but lacks the healing aspect of the Quirk. The user can generate pink energy, and if they touch someone with it, it will force them to become twelve years younger.

If this happens, the target will lose all the strength gained during those twelve years. If the user continues to use this power on the same target, he can revert them back to a time when they were never born – which would be erase them from existence. If the Return-Return fruit were canon, it could be used to keep beloved characters alive for as long as possible. It could also be used to defeat someone like Imu, if he is truly immortal.

8 Through-Through gives the user the power to pass through objects

• Devil Fruit Type: Paramecia
• Known user: Tanaka

The Through-Through Fruit doesn't have much offensive potential, but it's still an interesting and useful Devil Fruit. The user gains the ability to pass through any type of solid object. In essence, the power of the Through Fruit is intangibility, and the user can extend this intangibility to other objects through physical contact. Unfortunately, the user cannot phase through living beings.

This Devil Fruit makes escaping much easier, so it would be a good option for cowardly characters like Nami or Usopp. It would also work well for perverted characters like Absalom. It could even be used to help protect important characters because the user can make them immune to sword attacks, bullets, and non-biological Devil Fruit powers.

7 The Gol-Gol fruit allows one to manipulate gold

First appeared in One Piece Movie: Gold

• Devil Fruit Type: Paramecia
• Known User: Gild Tesero

There are several Devil Fruits that align perfectly with their user, and the Gol-Gol Fruit would be well suited for a thief or any type of villain obsessed with wealth. It would give this character the power to telekinetically manipulate gold, but it will only work if they physically touch that piece of gold. Once they make contact, they can manipulate that gold whenever they want.

The user can make the gold change between solid and liquid states and can shape it however they want. They can encase others in golden tombs or give themselves golden armor.

6 The Pet-Pet Fruit is Perfect for a Villain

First appeared in One piece Episode 625, “Intense! Aokiji vs. Doflamingo”

• Devil Fruit Type: Paramecia
• Known User: Race

Tama's Devil Fruit can instantly tame any animal, but the effects only last about a month. The Pet-Pet Fruit is slightly stronger because can control any living being, and can do so almost indefinitely. The user can create a gel-like collar, and if the collar is successfully placed around the victim's neck, the user can command them to do anything. That being said, the collar will break if the victim's willpower is extremely strong. The collar will also disappear if the user is rendered unconscious.

If necessary, the user can place the collar on themselves. By doing so, the user can command their own body to utilize its full potential. This is the kind of Devil Fruit that a canon villain like Doflamingo or Kaido would love to have at their disposal. If a Celestial Dragon possessed the Pet-Pet Fruit, fans would dislike them even more because they would likely force the slaves to harm their families.

5 The hot fruit makes the user immune to extreme temperatures.

First appeared in One piece Episode 326, “Mysterious Pirate Party! The Sun and a Dangerous Trap”

• Devil Fruit Type: Paramecia
• Known user: Don Accino

The Straw Hats encountered the Accino Family and the Heat-Heat Fruit after emerging from Water 7. If one eats this Devil Fruit, they will gain the ability to produce and control large amounts of heat. This power is similar to the Heat-Heat Fruit used by Charlotte Oven of the Big Mom Pirates, but there are a few key differences. Unlike the Heat-Heat Fruit, the Heat-Heat Fruit makes the user immune to extreme heat and cold.

The power of the Hot-Hot Fruit is also directly linked to the user's emotions. If the user is calm, the heat will be quite safe, but the heat can reach dangerous levels if the user is angry. With enough heat, A Hot-Hot Fruit user can melt anything they touch. This would be the perfect Devil Fruit to use against Fleet Admiral Akainu or Kuzan because it would theoretically nullify their Logia powers.

4 The fruit that grows and grows would improve Usopp's plant-based weaponry.

• Devil Fruit Type: Paramecia
• Known user: Binz

The Neo Marines also possessed the Grow-Grow Fruit – which has decent offensive potential. With it, the user can super-accelerate the growth of plants, and the plants can grow quite large. The Grow-Grow Fruit also allows the user to control the plants that have been grown. They can use the plants for defense, but in most cases, the plants will likely be used to contain one or more enemies.

If the Grow-Grow Fruit were canon, it would be a great power for Usopp since he uses plant ammunition. Admiral Ryokugyu appeared at the end of the Wano arc and displayed his plant-based Logia. In addition to fire and Haki, The Grow-Grow fruit would theoretically be the best way to combat Ryokugyu's Devil Fruit – which turns him into a plant-human.

3 The more fruits can increase the strength and speed of an object

Luffy faced the More-More Fruit during the timeskip, and it proved to be a dangerous Devil Fruit. If the user physically touches something, they can amplify the speed and size of the object by up to 100 times. The user can turn a small pile of rocks into deadly projectiles and can use his power to turn a cannonball into a large, high-velocity bullet.

The More-More Fruit can also increase the user's speed. With this speed boost, the user can put more momentum behind their attacks. They can also increase the size of their sword or fist to make their attacks even stronger. Luffy had a hard time dealing with this Devil Fruit because it is strong in the right hands. If it were canon, the More-More Fruit would be great for melee fighters like Koby or Garp.

2 The Whisper-Whisper Fruit Allows One to Speak to Animals

First appeared in One piece Episode 54, “Premonition of a New Adventure! The Intriguing Girl, Apis”

• Devil Fruit Type: Paramecia
• Known user: Apis

The Warship Island arc takes place immediately after the Loguetown arc, and is One piecefirst filling arc. This arc introduced the Whisper-Whisper Fruit – which offers a power that many people wish they had in real life. It gives the user the ability to telepathically communicate with animals. Unlike Shirahoshi's Sea King ability and Tama's Millet-Millet Fruit, this power cannot control an animal or manipulate its will.

That said, the Whisper-Whisper Fruit is still a fun power to have. Animals can spy on targets or locations and warn ships if danger is approaching. This power works best if the user is able to develop a bond with the animal. The Straw Hats encountered several animal companions throughout their journey, and the Whisper-Whisper Fruit could have made communicating with them easier and more fun.

1 The Clank-Clank fruit can disassemble and reassemble objects.

• Devil Fruit Type: Paramecia
• Known User: Douglas Bullet

The Clank-Clank Fruit is similar to the Op-Op Fruit, but in some ways it is a bit better. It gives the user the power to telekinetically disassemble any object, and they can then reassemble it however they want. Like the Op-Op Fruit, it can manipulate matter to a certain extent, but the Clank-Clank Fruit is not restricted to a specific area. The user can use this power to build ships, submarines, metal suits, and various mechanical structures.

The Clank-Clank Fruit becomes even stronger with the awakening of the Devil Fruit. If this happens, the user will be able to reshape the landscape of an entire island. In the right environment, they can use the landscape to create a colossal weapon. If the Clank-Clank Fruit were canon, it would be the perfect Devil Fruit for a shipwright or engineer like Franky to have. They would be able to build whatever they wanted and fix things much faster.
