Stamp Stamp Fruit
[Ohin Ohin No Mi]
(オーインオーインの実)

The Ohin Ohin No Mi is a Paramecia-Type Devil Fruit that allows the User to Create Different Stamps known as ViStamps and Contracts, making the user a Stamp Human. This also allows the user to see and Interact with the Devils that Live inside of Devil Fruit Users, including their own. The Ohin Ohin No Mi was Eaten by Y/n ReVi.

During his childhood and time as a Slave, while being fed his daily meal Y/n witnessed the Horned Melon he was given by his Best Friend and Fellow Slave, Futan, Transform into the Ohin Ohin No Mi. In a mass of Confusion and Awe, Y/n hesitantly Ate the Fruit, gagging and Remarking that it tasted like least favorite thing in the world, which just so happens to be Ink.

Entomology | ^

● Ohin Means Stamping in Japanese

Appearance | ^

The Ohin Ohin No Mi is a Pink, Cone Stamp Shaped Spiky Fruit with the Stereotypical Devil Fruit Swirls going Up the Different Spikes. The Inside of the Fruit has Jelly that appears Pitch Black and Thick with the Consistency of Oobleck, as Y/n was able to pour the Liquid into his mouth, but found himself having to chew it afterwards.

Strengths and Weaknesses | ^

Strengths

The Biggest Strength of the Stamp Stamp Fruit is Vice. Vice is the Devil that was inside of the Ohin Ohin No Mi and now Resides inside of Y/n's Body. Unlike others, Y/n can see and hear Vice, allowing for the Devil to help him in a multitude of ways, like Possessing Objects or Telling Y/n when he notices something nobody else has.

Thanks to being able to see the Devils inside of Devil Fruit Users, Y/n is able to quickly Discern what Devil Fruit Powers a person just by looking at them.

Using his Contracts, Y/n's Body not only becomes more Durable, but is also able to deal a lot more Damage, easily destroying Stone and Concrete with a Single Kick, and even being able to easily shatter Steel with that same power after Timeskip.

Using ViStamps and Contracts together, Y/n is easily able to Copy the Technique of people he's Made deals with, and even their Devil Fruit Powers.

Weaknesses

One Major Weakness of Y/n's Fruit is also its Greatest Strength, Vice. Vice being very energetic, outgoing, along with the ability to Break the Fourth Wall, he can be very distracting towards Y/n causing him to get injured during a fight multiple times. However when times get tough, Vice gets serious and easily becomes a Powerhouse when fighting at Y/n's side. Y/n has also been able to minnigate Vice's meddling by using Contrats that allow him to fight alone, although he sacrifices the use of their Powerful Remix forms.

Vice and Y/n are permanently connected, meaning if Y/n Dies, Vice Dies and vice versa. Y/n like all Devil Fruit Users is weak to Water, like Fish-Man Karate and Seastone, however, Y/n knows this well and does his best to avoid water as best he can… Vice on the other hand tends to forget… often, causing him to come in contact with Seastone and Ocean Water often, but interestingly enough, when Vice is affected by Water, Y/n feels that Exact Same Weakness, finding it hard to breathe when Vice is Submerged in Water, or becoming Exhausted when he Touching Seastone, and vice versa.

Usage | ^

Deals

The Stamp Stamp Fruit allows Y/n to create ViStamps, by Stamping other People with a Blank ViStamp, once a Vistamp is Created using Someone Else as a Base, Y/n can gain access to some of their abilities and Skill Sets while also being Set to a Specific and seemingly random Animal.

This Power Works Best when Y/n makes a Deal with Other Devil Fruit Users, as he Copies a Small Extent of their Devil Fruit Powers inside of the Stamp allowing him to call on those powers when he uses one of his Contracts. The best Example of this when Y/n made a Deal with Luffy, creating the Brachio ViStamp, while using this Stamp to access his Brachio Genome, Y/n is to Stretch his Limbs to a very limited extent, be unaffected by most Blunt Damage, and even bypass Enel's Lightning Body and Damage him, although before Timeskip, Y/n has an extremely hard time calling upon others Powers, usually only being able to in Remix Forms or for Special Finish Attacks.

Contracts

What Y/n calls Contracts are oddly colorful Belt like Devices and Weapons that Y/n and Vice use to transform and attack using different ViStamps.

Using the Belts and a ViStaml, Y/n can Transform into new armored Forms called Genomes using the different ViStamp's Animals as a Base.

By using the ReVIce Contract Y/n and Vice transform into Kamen Rider Revi and Vice, better known together as Kamen Rider Revice. This Contract allows Y/n and Vice to fight together as a Duo, along with using Special Contract Weapons like The OhinBuster50 The OsutoderuHammer50 and the ReVIcelasher.

By using the Two SI-Contract Y/n is able to transform into Kamen Rider Evil and Kamen Rider Live using the Bat ViStamp. This Contract allows Y/n to fight on his own, while also being able to call upon the Devil Fruit Powers of Gecko Moria as Evil, and Nico Robin as Live, although after Thriller Bark, Y/n makes a New Deal with Brook using the Bat ViStamp, causing his Evil form to lose it's limited use of the Kage Kage No Mi in exchange for the Yomi Yomi No Mi's Second Life, allowing him to fight more recklessly as Evil and Live.

By using the Demons Contract along with the Spider ViStamp, Y/n is able to transform into Kamen Rider Demons. This Contract allows Y/n to call upon the Devil Fruit powers of Donquixote Doflamingo, although due to the overwhelming power, Y/n loses a bit of his Humanity while In this form in exchange for extreme power, so he tends to use this Contract the Least.

By Using the Libera Contract along with the Cobra ViStamp, Y/n is able to transform into the Feminine form of Kamen Rider Jeanne. This Contract allows Y/n to use the Skills of his Long Lost Friend and Former Slave turned Kuja, Futan. Being extremely close to Futan before their separation, and his drive to see her again has caused this Deal and Contract to become one of Y/n's Strongest, giving an Extremely Powerful Grasp of Haki while using this Combo of Stamp and Belt. After Timeskip this form would only becomes stronger along with Y/n's Extreme Grasp of Busoshoku Haki.

Pre-Timeskip Attacks/Forms | ^

●Eagle/Nami Deal/Stamp

●Kamakiri/Usopp Deal/Stamp
Using this Stamp, Y/n gains a bit of Usopp's Accuracy, along with a great boost when it comes to running, hiding and Lying to enemies… but in exchange for all that he becomes extremely weak in defense.

[Didn't know what to do here...]

●Bat/Robin & Brook Deal/Stamp
Using this Stamp, Y/n gain's Robin's Dark mind, traumatizing him the first time he did it, causing him to never use this stamp Untransformed again.

Kamen Rider Revice: 

While Transformed into Revice, Y/n and Vice gain a mass of Power from their different Genome forms based on the animal and ViStamp Deal. The two of them can also Access forms known as Remix, where the two of them combined their forms and powers to become even stronger.

●Rex Genome
The Form Y/n and Vice use most often. It's the most basic and balanced of their forms.

■Rex Stamping Finish
Filling their legs with a mass of power, Y/n and Vice slam an enemy with the full power of their kick, causing the Symbol of the Rex Stamp be imprinted into an Enemy as they explode after Vice's countdown.

>Rex Remix
With Vice turning his legs into T-Rex Legs, Y/n then climbs up, standing on Vice's legs and butting his butt into the Devil's face, he clasps his hands together as their Remix is formed.
This form allows the two of them to Unleash Powerful Stomping Shockwaves with Vice's Dino Legs and Slashing attacks from Y/n's Dino Jaw Arms.

●Megalodon Genome
Being Zoro's Deal, this form is Y/n's Blade/Slashing Form, as he wields Two Blades on his Arms, Y/n is able to perform Zoro's 2 Sword Style Attacks, along with his 3 Sword Style attacks when using his finishing attacks. Vice on the other hand is much faster and uses his legs as slashing attacks, oddly enough his Attacks resembles Sanji more than Zoro In this form.

■Megalodon Stamping Finish
Vice dashes at an enemy with extreme speed, kicking them over and over and leaving them open for an attack, before Y/n attacks, slamming an enemy with Zoro's 3 Sword Style Oni Giri Attack.

>Megalodon Remix
Doing a Handstand, Y/n then grabs Vice's Hips as their Remix is formed, turning Y/n's Legs into the top half of a Shark Mouth, while Vice's head and arms are the bottom half of the head while his Legs are the tail of the Remix.
In this flrm, Y/n easily flys through the air with extreme speed, easily slashing and attacking enemies. He can even pull off a Special attack with Zoro using his 108 Caliber Phoenix.

●Eagle Genome
Being Nami's Deal, this form is Y/n's more intelligent travel form as it lacks combat power, but makes up for that weakness in his use of wind power and illusions… Although in this form Vice is at his weakest and tends to use it to make an impression/make fun of Nami, much to her extreme annoyance…

■Eagle Stamping Finish
Usually used while in Remix Form, Y/n and Vice create a tornado around themselves and slam into an enemy.

>Eagle Remix
By putting Y/n on his shoulders, Y/n and Vice create the Eagle Remix, which allows them to fly extremely fast, also allowing them to unleash a powerful tornado screw attack.

●Kong Genome
Being Franky's Deal, this form is Y/n's and Vice's more Tank-like form, in an almost literal sense. Much like Franky's own Arms, Y/n can shoot his Kong fists like rockets and can punch pretty hard, he can also build simple things extremely fast. Vice can shoot missiles from his shoulders and cannons from his arms much like Franky. But the two of them also need Cola to unleash this Form's True Overwhelming power, or they'll be forced out of it or just get lazy and start loafing around.

■Kong Stamping Finish
Slamming his fists onto the Ground, Vice caused a shockwave that sends his enemy flying into the air, before Launching Y/n after them. Y/n then reels back his right fist and slams it into the target, launching them into the ground with a mass of power.

>Kong Remix
Vice Does a Handstand and Y/n sits on top of him, hugging onto the Devil's tail. 
This is one of Y/n's most powerful attacking forms, allowing Y/n and Vice to smash enemies with a mass of speed and power, becoming a strong unrelenting beast. Oddly enough, this Remix can also be combined with the other Straw Hats, Usopp, Franky, and Chopper, to create Straw Hat Gattai, Mega Mecha Gorillazilla. Which had enough power to even send Oars Flying Back with a Single Punch. Vice and Franky remark that the form would have been even to defeat the Giant Zombie in one hit if Sanji, Zoro and Robin joined in with them.

●Mammoth Genome
[Still don't know...]

■Mammoth Stamping Finish

>Mammoth Remix
With Vice turning his backside towards the enemy, the Devil and Y/n put their heads together using Y/n's boomerangs as Tusk as they form this Remix. This form is a more One Hit Wonder kind of form as it fist builds up speed before ramming into an enemy full force, leaving them completely open for the Mammoth Stamping Finish. This Remix has able been able to combine with the other Straw Hats, Usopp, Franky, and Chopper, to form Straw Hat Gattai, StrawLiner MaxiMammoth, which was fast enough to distract and dodge Oars attacks while also slamming the zombie with some powerful hits of their own, creating shockwaves with each attack.

●Petra Genome
Being Enel's Deal, this form grants Y/n an extreme mass of speed, allowing him to dash around with an electrical aura sparking around his body, even being able to run up and on walls and cliff with ease. Y/n usually fights alone in this form, unless Nami's Waver is Near, allowing the Devil to possess the White Sea Vehicle and transform it into what he called the "Nice Vice Sky Bike" allowing him to fly through the air, create clouds under himself to surf on, summon wings made out of Lightning to attack, or even shoot special bullets made by Franky and Usopp at enemies.

■Petra Stamping Finish
Dashing/Flying forwards with extreme speed, Y/n and Vice are surrounded in lighting before they slam into an enemy from opposite sides.

>Petra Remix
This Isn't like the other Remix forms as Y/n simply rides on Vice or performs a combo attack with him, surrounding the two of them in Lightning.

●Lion Genome
Being Sanji's Deal, this form Gives Y/n in extreme increase in Kick Power, along with Pyrokinesis, allowing him to easily use Diable Jambe to dramatically increase his kicking power. Vice on the other hand, due to his love of cats, prefere to hack and slash with his Claws using them like blades… oddly enough his fighting stay is more like Zoro's than Sanji.

■Lion Stamping Finish
Surrounding his Feet/Claws in flame, Vice and Y/n charge forwards, with Vice Slashing the enemy before Y/n finishes them off with a powerful burning kick.

>Lion Remix (Cat)
By having Y/n get on his hands and knees, Vice then lifts up Y/n's legs towards his chest, causing the two of them to transform into the Lion Remix… which oddly enough looks like Japanese Golden Cat Figure.

This Form servers little to no purpose, and was only used because Vice really likes cats… although it did lower the enemies expectations for how strong the true Lion Remix holds.

>Lion Remix
By having Vice get on his hand and knees, Y/n holds up the devil's legs before the Lion Remixed is formed.

This Remix is one of the fastest and strongest, allowing Y/n and Vice to jump around hack and slash at enemies like crazy, leaving them little to no time to react and think of a way to stop this new power.

●Jackal Genome
Being Chopper's Deal, this form is… almost useless in combat… in this form, Y/n is a bit faster, but he can also trade out his speed for strength, or strength for defense, much like Chopper using his different Points. Vice in this form is turned into a Snow/Surf/Skateboard, which Y/n uses to get around faster.

■Jackel Stamping Finish
Gripping Vice, Y/n uses all of his power to slam the Devil into an enemy.

>Jackal Remix
Much like the Petra Remix, Y/n simply rides ontop of Vice… nothing else really changes…

●Kamakiri Genome
Being the Deal of Usopp, this is Y/n's Ranged/Sniper form, giving him a mass of accuracy, it also allows Y/n to run and hide extremely easily. Vice gets no weapon in this form, but his speed is greatly increased.

■Kamakiri Stamping Finish
Vice gets sucked into Y/n's Kamakiri Arrow as he draws the bow back, before unleashing a powerful Finishing attack that follows it's enemy and can easily pierce through walls.

>Kamakiri Remix
Doing a handstand, Vice places his feet on Y/n's shoulder, completing the Remix.

This form allows Y/n to transform his Arrow Weapon into twin blades allowing him and vice to speed around the BattleField hacking and slashing enemies with extreme speed and power.

●Brachio Genome
Being Luffy's Deal, this is easily Y/n's strongest form, allowing him to stretch his body, although he needs to grab onto something and force his body to stretch. While Y/n uses Luffy's Rubber to attack, Vice uses Luffy's rubber for defense, becoming a Wall.

■Brachio Stamping Finish
With Vice holding Y/n's Arms, the boy rushed forwards allowing his arms to stretch before Vice let's go, slamming an enemy with his version of a Gum Gum Bazooka, called a Brachio Brachio Brazoochio.

During his "Fight" against Bartholomew Kuma at the Sabaody Archipelago, Y/n and Vice in their rage were able to stretch their arms just like Luffy, the two of them slamming Kuma with two Gum Gum Rifles which they named the "Brachi Gum Revi Vice Rifle", although powerful enough to cause a shockwave and pop bubbles far above them, this did no damage to the warlord thanks to his Devil Fruit Power.

>Brachio Remix
Vice gets on his hands and knees before Y/n jumps up and stands on his back before holding his arms up so that his elbows are our and his arms are protecting his face, forming the Brachio Remix.

This Form is oddly powerful as Y/n and Vice can Stretch as freely as Lucy, with Y/n being used as a Mace swung around by Vice.

Kamen Rider Evil 

Using the Two SI-Contract's Sword Mode, Y/n is able to transform into Kamen Rider Evil. In this form he fights alone without Vice and loses the ability to use Remix Forms.

●Bat Genome 
(Before Thriller Bark)
Being Gecko Moria's Deal, Y/n is able to use a limited version of the Kage Kage No Mi's power, allowing his own shadow to come to life and attack with him, Vice has been shown to be able to possess Y/n's shadow, but says it feels weird and tends not to do it.
While in this form, Y/n becomes noticeable More Violent, usually speaking harshly and becoming more ruthless in a fight, nearly killing his enemies or getting so caught up in a fight that he accidently attacks his friends, not caring if they get hurt.

(After Thriller Bark)
Being Brook's Deal, Y/n gains an odd version of he Yomi Yomi No Mi's ability, being able to regenerate and quickly recover from attacks. He can also jump higher and run across water like Brook being lighter than normal. In combination with Robin's abilities Y/n can also make Bat Wings allowing him to Fly.

In this form, Y/n gains a bit of Brook's personality, laughing as he fights and also using his swords skills, even using his Bat Soundwave to create musical attacks. He's also more considerate of his enemies in this form, making Bat Puns.

■Bat Darkness Finish
(Before Thriller Bark)
Using the Bat Stamp, Y/n surrounds his blade in his own shadow and using it to launched a ranged slashing attack.

(After Thriller Bark)
■Bat Mortis Finish

Using the Two SI-Contract's Gun Mode, Y/n is able to transform into Kamen Rider Live.

●Bat Genome
Being Robin's Deal, Y/n is able to use an odd version of the Flower Flower Fruit, placing the Bat Mark on enemies he shoots, causing bat wings or Legs appear out of the marks, disarming or flying the enemies into the air, leaving them open for further attacks.

After Thriller Bark, Y/n is able to use a bit of Brook's abilities, allowing him to move more sporadically and attack more unpredictably.

■Bat Justice Finish
Shooting at a Wall, Ground or Ceiling, Y/n places a Bat Mark before a mass of the Two SI-Contract's Barrels appear, blasting anyone infront of the guns with a mass of bullets.

After Thriller Bark Y/n combines this with his new found speed, allowing him to dash around his enemy and slam them with evenmore shots while they're already being slammed with his first barrage.

Kamen Rider Demons

Using the Demons Contract and the Spider ViStamp, Y/n can become one of his strongest forms, Kamen Rider Demons. In this form he fights in his own and loses Remix, but gains a New Power Add.

●Spider Genome
Using the Spider Genome Y/n transformed into Kamen Rider Demons… although in this form Y/n is described by Vice as becoming a True Demon King, as he becomes a Ruthless and Raging Being of Destruction, caring not for friend or foe and simply looking to get stronger and fight, laughing like a maniac as he fights.

Being the Deal of Donquixote Doflamingo, Y/n gains the use of the String String Fruit, being able to create Threads and use them in a mass of creative and deadly ways.

■Demons Finish

Creating Razor Sharp Strings from his fingers, Y/n laughs like Crazy as he slashes his enemy over and over, easily hacking and slashing the world around them. He then wraps his enemy in string before pulling them close and kicking them with a mass of power.

■Rex, Brachio, Megalodon, Kamakiri, Eagle, Jackal, Bat, Kong, Bat. Demons Requiem!

In a rage, Y/n calls upon the power of all the Straw Hats and Unleashed a Powerful Kick filled to the prim with power, although we never got to see the affects of this attack on a person due to Kuma launching him away to the Calm Belt's Island of Death AKA Grim Reaper Grave, but from the Large Crater seen in the middle of the Island, and the Kuja Warrior Veteran stating that the Crater Hadn't been there before and comparing it to a Meteor Crashing, it's safe to say that the power of the kick would have been devastating. Even after timeskip we've never seen Y/n try this attack again.

● ALL Genomix

By Using every single stamp Y/n has at his command, he becomes a Hulking Destructive Demon King of Pure Rage and Power, able to easily take down Monsters and fight off a group of some of the Strongest Kuja Warriors.

Kamen Rider Jeanne

[Haven't seen her in action yet]

Post Timeskip | ^

Timeskip Training

The Island of Death known as Grim Reaper's Grave, an island so large is acts as a Bridge across the Calm Belt into the Grand Line… although the island is filled to the brim with deadly and demonic creatures known as Reapers that kill all people that step foot on the island. The Strongest of the Kuja come to this Island annually and do their best to survive for an unspecified amount of time, proving themselves worthy of becoming Kuja Pirates.

After being Defeated at the Sabaody Archipelago by Kuma, Y/n is launched onto this island, creating a massive meteor like crater as he landed. Filled with Anger Rage and Sadness, Y/n uses all of his Stamps and the Demons Contract to Genomix into a massive hulking demonic beast. Using this power, Y/n was easily able to slaughter all the Reapers that tried to attack him, causing him to be the only creature in the world these monsters feared.

Later a Group of up and coming Kuja women wishing to prove themselves as Kuja Pirates arrived on the island led by Futan, former Slave and Y/n's Long Lost Childhood friend. After encountering the Demonic Y/n, the Futan and her group of Kuja were forced to fight against Y/n, easily falling to his overwhelming power and being forced to run from the beast. After a few days of running, Futan and her group for Amazons had been backed into a counered by the Berserk Y/n, suddenly the News had arrived to the Island, a mass of papers being dropped off by bird. After a Paper had landed on Y/n's head the Demon in curiosity looked at the paper, only to be begin crying tear of joy and roaring into the heavens as he saw the Message Luffy had left after his Escape from Impel down and Battle at Marinefort. After his tears dried up, Y/n had transformed back to normal, causing him to fall unconscious afterwards, quickly and easily shocking the Kuja and especially Futan as she had finally come face to face with her Old Friend after all these years. She went to help the boy, much to the confusion of the other women, only for Y/n to suddenly be grabbed and taken away by a group of Reapers. 

After Searching for Y/n with her Group of Amazons, Futan was shocked to see that Y/n had regained consciousness once again, and not only that, but that the boy was commanding the Reapers like he was their ruler… but even more shocking was that Y/n had lost all memories of his old friend due to his over usage of the Demons Contract.

After explaining herself and even the reason why the Kuja are on this island in the first place, after hearing this, Y/n then proclaims,

Y/n: "I honestly don't care if you were my friend in the past or not… Because there's only one thing that matters to me right now! And that's Getting Stronger! I can't lose my friends ever again! I MUST GET STRONGER! STRONG ENOUGH TO PROTECT MY CREW FROM EVERYTHING!"

Stamping himself and summoning Vice, Y/n then glared at the Kuja, before speaking up once again.

Y/n: "You wanna survive on this island and become pirates, right? To follow under your captain and make them King of the Pirates… Then it never mattered if we were friends, because No Matter what, I will make Monkey D. Luffy the King of the Pirates! And I won't let you stand in his way!"

Vice: "YAHOO! You gals wanna be Pirates so bad? Then you're initiations changed a tiny bit! YOU'VE GOTTA SURVIVE ALL OF US!"

After this, Y/n and Vice began the Kuja's new trial, forcing them to survive their seemingly onslaught of Combat as Y/n now commanded an Army of Reapers of all different Shapes and Sizes leaving no place on the Island Safe. After fighting against the Kuja for the next 2 Years, Y/n and Vice quickly learned about the Different Types of Haki Via Combat, even learning it with beyond impressive speed.

Haki

After his little war against the Kujas, Y/n and Vice quickly learned about Haki as they fought against them, quickly learning and incorporating it in their own fighting style.

Armament/Busoshoku Haki

During his Two Year Training, Y/n not only Mastered the Basics of Armament Haki, but also one of it's Advanced forms, Emission. His mastering has gone so far that his Hair is permanently imbued with Armament Haki, making it a Deep Jet Black Color, but it also cannot be cut or Damaged, not even by Luffy, Zoro and Sanji's Combined Power. Y/n can not only Imbue his entire body with Armament Haki, but he can also project it infront of himself, creating a 5 Inch Thick Force Field when he's standing still.

Vice on the other hand, can only use Armament Haki to Harden his Fists or Imbue a weapon with it.

Observation/Kenbunshoku Haki

Y/n has no grasp of this kind of Haki whatsoever, but he has substituted it with oddly powerful animal instincts and senses that he picked up from the Reapers. His sense of smell has grown greatly, but he has also been able to smell Malice from people showing a small if not unique grasp of this Haki.

Vice on the other hand has seemingly Mastaered Kenbunshoku Haki, as he can sense people, emotions, incoming attacks and can even see a tiny bit into the future. His ability to Break the Fourthwall is also a type of Unexplained Haki that only he seemingly has access too.

Emperor/Haoshoku Haki

Y/n has displayed a weak showing of Emperor's Haki but has yet to use it consciously, as while he was All Genomixed Demons, he was able to use Domination Haki to force all of the Reapers under his command, even riding on the back of a Reaper Seaking to get back to the Sabaody Archipelago. He also used Incapacitation to knock out the Kuja when he learned of Luffy's Message while in his demonic form.

Y/n has also "The Qualities of a King".
As a Child he was constantly feared by his enslavers even before he had gained his Devil Fruit powers, forcing them to place him in solitary and torture him in fear of his rebellion once he grew older. Y/n's odd and powerful forms, along with his Unbreakable Will to Serve and Protect his friends by defeating every enemy in his way has caused onlookers to confuse Y/n for a Demon, gaining the Title "Demon King".

Vice has shown no signs of Emperor's Haki.

And that's all I thought of.

Tell me what ya think!

Anyways!
