Vice

is one of the two main protagonists in Kamen Rider Revice. He is an inner demon who transforms into . With his host Ikki Igarashi, together they are .
==History==
===Background===
Vice was born as the inner demon of Ikki Igarashi after the latter witnessed his father Genta Igarashi, who was possessed by Vail at the time, burning down the Happy Spa bathhouse. To erase his memories of that tragic night, Vice formed a contract with the young boy while staying dormant until he had reached of age to ensure the contract's confidentiality. 
Through undisclosed methods, Vice was able to thwart Vail and save the Igarashi Family in the process. Despite being dormant, Vice was witness to most of Ikki's life events, including the accident with Koji Ikeda that caused the two of them to quit soccer.
===Becoming Kamen Rider Vice===
One day, Vice made his presence known to Ikki and caused trouble to him. During Daiji Igarashi's ceremony at Fenix, the event is sabotaged by the Deadmans. Vice was turned corporal when Ikki used the Rex Vistamp to protect his family. However, he quickly broke the agreement and prepared to eat Ikki's mother. However, he was stopped after Ikki equipped the Revice Driver. After Vice fought with Ikki against the attacking Deadmans, he was christened by George Karizaki, as 'Kamen Rider Vice', a name he called himself from that point on.
While Vice tries to go to Ikki to make him corporal again, Ikki was angered by Vice's mischief and hunger for humans. While Ikki opted to use the Revice Driver to fight occasional Deadmans, he refused to use the belt until Vice agreed to no longer harm innocent people. Vice honored his words and continued to help Ikki protect humanity from the Deadmans. Despite that he remained as mischievous, he slowly became a trusted companion to Ikki and their bond would additionally improve as the two Riders worked coherently against their opponents.
===Kamen Rider Revice: The Movie===
Kamen Rider Revi and Kamen Rider Vice would appear to fight off the Giff Juniors led by Orteca who were terrorizing a theme park. While the pair later retired the day off in the bathhouse, Daiji would inform them of a new Deadmans attack elsewhere in the city. Arriving to battle the Spider Deadman, Revice would assume the Megalodon Genome to vanquish the monster together. After their victory, Revi let Vice roam free to soak himself in the bath.
===Time of the Three Igarashi Siblings===
As the battle kept ongoing, Revice would come across the mysterious Kamen Rider Evil, who had taken over Daiji's body. Hiromi Kadota would assist the pair as Kamen Rider Demons until Ikki gets through to his brother as Daiji evolves as Kamen Rider Live. While the Igarashi brothers becoming active Kamen Riders, their sister Sakura Igarashi would find the means to become Kamen Rider Jeanne. He would also end up being in the wrong foot with George Karizaki after complaining about Jackal Genome's design, which came to bite him in the back occasionally.
Despite his retaining his mischievious ways, Vice had grown as a trusted ally to Ikki. Vice was temporarily turned corporeal to fight alongside his human host during the Deadmans' invasion at the Fenix Skybase. While Ikki was granted a new form with the Barid Rex Vistamp, Vice was disappointed that he didn't get a new form so he fashioned himself a shield using Barid Rex's egg shells.
===Kamen Rider: Beyond Generations===
While Vice and Ikki continued his battles with the Deadmans, he reunited with the Sword of Logos' members who came by to Happy Spa. However, their encounter came at a better time as the demon Diablo emerging to threaten the Earth's future, leading to Fenix's Kamen Riders and the Sword of Logos joining forces. They would also encounter time-displaced Shocker scientist Ryunosuke Momose, who sought to make amends with Hideo, his young son he left behind in 1971, who is now an adult man in 2021.
Vice joins Daiji, Sakura, Touma, Rintaro, and Yuri to venture to the future, while Ikki stayed behind in the present to help defeat Diablo. He would meet an elderly George Karizaki, who assisted the heroes by granting them to access to Clone Riders forms. Vice would assume the forms of Black RX, Fourze, and Woz. Upon returning to the present, Vice would join forces with Revi, Xross Saber, and the benevolent Century to battle the giant Diablo. Revice would also access the Neo Batta Genome to vanquish Diablo for good.
===Dismatling the Deadmans' Operations===
When Ikki was forced to battle Yasushi Kudo after he had escaped Fenix's custody, Vice noticed how saddened Ikki was after Kudo accused him for acting without considering the consequences. Vice encouraged him that these traits were okay and just be himself. This motivated Ikki to continue fighting to help others, while trying to change for the better. Vice would carry on to fight as Kamen Rider Vice to shut down the Deadmans' operations.
===Kamen Rider Revice: The Mystery===
After fighting the Orangutan Deadman, Ikki and Hiromi follow its trail to Pension Nijitenka where they meet its staff, the proprietor Suzu Saionji and the caretaker Shinzo Hanawa. While trying to search for the Vistamp holder amoung its lodgers, Vice is stringed along for a murder mystery when one of the suspects ends up dead. This leads to Vice playing detective as he, Ikki, and Genpachiro Otta investigate the lodge and flush out the suspect behind the attacks.
When Hiromi ends up injured, Vice ends up finding out one of the suspects is actually an Orphnoch named Naoya Kaido. While Kaido is not the culprit, it turned out to be Suzu who orchestrated the monster attacks. It was revealed Suzu lured Ikki to Pension Nijitenka as part of her plan to kill him, as he was the pinacle of George Karizaki's research. Joining forces with Ryu Terui, Vice and Ikki prevail against Suzu after she transformed into Oblivian.
===The True Value of Buddies===
Wishing to liberate the Phase 3 Deadman from their demons, Ikki and Vice undergo a VR training simulation to harness the Volcano Vistamp. Orteca unleashes a new breed of demons known as Gifftarians, and Vice could finally be upgraded into Barid Rex. After Ikki was injured after failing to withstand the Volcano Genome, Vice encouraged him to keep fighting despite the burdens he face. With the pair strengthening their ties, Revice was able to use a wonderful combination of fire and ice.
With Giff's resurgence approaching, Vice begins to experience sharp headaches. Like Ikki, Vice would take notice of Hiromi's declining health, remarking how cruel Karizaki used Hiromi as a lab rat. After the operation to capture Orteca, Vice is informed about a demon inside the Demons Driver. Orteca deliberately had himself captured to acquire the belt and transformed into Kamen Rider Demons, becoming a powerful force who defeated the Kamen Riders and knocking Hiromi off the cliff.
As Vice's headaches worsen, Ikki attempts to access a new form, Kamen Rider Jack Revice, using the new Rolling Vistamp. However, this results in Vice swapping places with Ikki and becoming corporeal. Vice displayed his distrust towards Fenix and Karizaki, even deliberately pretended to "betray" everyone to avoid being examined by Fenix. Later, when Karizaki offered to help Ikki's recovery, he initally refused. It was after Ikki's persuasion did he decide to agree. Eventually Ikki returned to normal, but merged with Vice.
While Vice tried to adjust sharing a body with Ikki, a new threat arose with Kamen Rider Vail, who turned out to be the Igarashi patriarch, Genta Igarashi. This caused Ikki to remember his erased childhood memories of his first encounter with Vice. Vice also becomes rampant due to Giff's revival approaching, causing him to turn berserk while inhabiting Ikki's body. After Ikki had to fight Vice within the subconscious to save him, Vice and Ikki harness the Thunder Gale Vistamp to unite as Kamen Rider Revice. After defeating Orteca, Vice and Ikki were restored back to separate bodies.
===The Ultimate Unity===
Following Giff's complete awakening, Ikki and Vice would battle true Gifftarians created directly by Giff, just as Hideo Akaishi began to unveil his true colors. When Ikki struggled to remember his promise to Koji Ikeda, Vice revealed the condition of the contract. As long as Ikki continues to fight for his family, he would slowly lose memories of his life. As Vice joined the Igarashi siblings to battle Hideo Akaishi, Vail resurfaced and became a menace to the family.
While Vice devoted himself to protect the Igarashi, he engaged in a one-on-one encounter with Vail. He accused Vice of abandoning his dignity as a demon and that humanity would reject him. As Vice feared such prospect, this caused him to be distracted in battle. Ikki later encouraged Vice that it is fine to act like himself, giving him the confidence to fight Giff. However, Akaishi would prove to be many steps ahead against the Kamen Riders by turning Akemi into a Giffdemos and depleting most of Fenix's forces.
Together with Weekend, Vice joined the plan to capture Akemi and extract Giff's cells from her body. However, the plan failed after Akaishi killed her. To complete the Giffard Rex Vistamp, Genta elected to provide Giff's cells to his body. As the operation itself nearly killing him, Ikki was able to stop it just in time. Before the Giffard Rex Vistamp flew back to Giff, Ikki and Vice were able to work together and split the Vistamp, allowing them to become Ultimate Revi and Ultimate Vice respectively.
While persevering in the demon war as Ultimate Revice, Vice apologetically reminds Ikki about their fighting would continue erasing the latter's memories due to their contract. Once the heroes finally come face to face with Giff, Vice continues fight with Ikki for the sake of the latter's family and the world. After Giff was briefly sealed in his dimension, Vice was temporarily brainwashed by the demon as Giff sought to re-enter the material world and destroy humanity. However, Vice joins the Igarashi three siblings and their demons to destroy Giff for good.
===Price of Transformation===
Several weeks have passed and the Igarashi family returns to a peaceful life. While Vice helps encourage Ikki to make new memories, their peace would come to a halt after Karizaki became Kamen Rider Juuga on a mission to destroy every Rider System harnessing the power of demons. Although Vice elected to fight in Ikki's place to not worsen his memory loss, the idea failed after he was unable to recognize his own parents. Vice later apologized to Genta and Yukimi for their contract.
With Karizaki being intent to threaten the family, Vice accepted Ikki's decision to confront him. He still expressed heavy guilt for causing Genta and Yukimi to despair. The very next day, Ultimate Revi and Ultimate Vice fought Juuga and were evenly matched. While still hesitant to continue fighting, Vice continues to fight alongside Ikki and save Karizaki's broken heart. Much to Vice's shock, Ikki loses memories of Daiji and Sakura in the aftermath, and he asks Vice who they were.
Vice accompanied Ikki when he leaves Happy Spa and moves into a new apartment together. However, he is unable to accept the fact that Ikki has forgotten his entire family and was desperately trying to end the contract, briefly confiding a solution to Karizaki. After a brief talk with Ikki, Vice learns his contract is still ongoing due to him being considered part of Ikki's family. With this knowledge in mind, Vice devised a plan to restore Ikki's memories with his family and their friends. The next day, Vice pretends to go on a rampage and fights Genta as Destream, goading Ikki into fighting him for the contract would end.
While the two fought, Ikki later deduced that Vice pretended to go on a rampage with the help of their friends and allies. Understanding Vice's intentions, they decided to instead battle each other on friendlier terms. The battle between Revi and Vice was intertwined with several Genome Changes and Remixes, reminiscing their past battles. This caused Ikki's memories of Vice to disappear one by one. When it came time for Vice to disappear, Ikki held him in his arms and Vice thanked Ikki for everything before he is finally erased for good, completing the contract and restoring Ikki's memories.
===Legacy===
A few months later, the Igarashi family sans Ikki would take a mini figure of a rubber duck and paint Vice's face onto it as a way to remember him, the demon who had protected them. Ikki discovers it one day while the family is cleaning their bathhouse, and attempts to throw it away but is immediately stopped by the rest of his family, who proclaims the demonic-looking duck to be their "guardian spirit".
Later that evening, while the family is having dinner, Ikki begins reacting in a strange yet familiar manner after finding the meat delicious, causing his family to look up in surprise for a brief moment, before they all begin laughing over Ikki's reaction.
=== Kamen Rider Geats × Revice: Movie Battle Royale ===
After Ikki had suffered a near-death experience following the assault of Balidelo and Izangi, he managed to call forth Vice back into existence after showing his resolve to live. Upon his return, Vice then fights alongside Ikki to take care of Balidelo and Izangi, as well as participating in Desire Royale.
However, due to being temporarily brought back into existence by Ikki's will, Vice can't stay for too long and is on the verge of disappearing. Girori would then provide him with a Desire Driver, which prolongs his existence a bit longer.
After emerging victorious and returning to a normal life, Vice says goodbye to Ikki again due to his time being up. However, this time, his memories stays intact within Ikki due to Ace's wish as the victor of Desire Royale.
==Other Events==
======
Kamen Rider Revi and Kamen Rider Vice arrived to challenge Asmodeus when he proved to be a formidable foe against the Kamen Riders and Super Sentai Rangers. While Vice made a dramatic entrance, Revi scolded him and pulled his tail. The surprise confused Kamen Rider Saber and Zenkaizer at first, but the heroes would soon watch as Revice working together to defeat Asmodeus with a Rex Stamping Finish before making their leave.
===Kamen Rider Saber===
Vice as Kamen Rider Vice intruded Kamen Rider Saber and Espada's battle against the Batta Deadman, only to be stopped by Ikki as Revi. In the final battle, both Revi and Vice assumed the Megalodon Genomes to briefly slash it, before the Deadman was vanquished by Saber and Espada. Although nobody could see him in his incorporeal state, Yuri was the only person who could see him and Vice was briefly driven away by Kougouken Saikou's light.Special Issue: A New Page, Opens
==Personality==
In contrast to the mellow and selfless Ikki, Vice is mischievous, flamboyant, and often blunt. He is incredibly self-serving, tricking Ikki into giving him a corporeal form, and claiming that he was "pretending" to attack Ikki's mother. With that being said, he is aware of his dependence on Ikki and protects him, if only to protect himself. Vice also expresses an interest in "eating" humans, but is constantly foiled by Ikki shoving his would-be victim aside, or using the Revice Driver to restrain him. Despite his reluctant vow to never attack other humans, he will often joke about breaking it, much to Ikki's chagrin. 
As the series progresses, Vice has become an reliable ally towards Ikki, occasionally giving advice and attempting to comfort him when the latter was feeling down. Being the inner demon born from Ikki himself, Vice is also willing to call Ikki out on his deepest flaws and insecurities. Vice has also begun to become a bit more selfless, not wanting Fenix and George to use Ikki as a lab rat as they did with Hiromi, and came to doubt their intentions. 
Over time, Vice became very protective of Ikki, having temporarily assumed a anti-heroic personality as a facade to protect him from being captured by Fenix. When George, who was the only hope in getting Ikki and Vice back to normal, was kidnapped, Vice panicked and proclaimed that he truly cared for Ikki when Sakura calls him out for not being so. After Ikki lost all of his memories due their contract, a guilt-ridden Vice reassumed a villainous personality to goad Ikki into terminating their contract, which would result in Ikki's memories returning while completely erasing any trace that Vice ever existed in his life. However, he quickly dropped his facade once Ikki saw through his plan and intentions, and the two were able to finish the battle on friendlier terms and put an end to their contract. In his last moments, Vice expressed content towards his time with Ikki, and was glad to be able to help him one last time.

*Demon Physiology: As a demon, he possesses the following characteristics:
**Enhanced Strength: Vice possesses enough strength to send the Rex Deadman flying through the air with one punch whilst not transformed.
**Imperceptibility: Vice cannot be perceived by anyone other than his host or another inner demon such as Lovekov, with both Yuri and Brave Dragon being exceptions. A solution is to summon him through Ikki's usage of a Vistamp, either on himself or through the Revice Driver. This can also be bypassed by possessing objects like Ikki's Gundephone50 and George's Vistamp Bar, allowing Vice to be seen and heard by others.
**Intangibility: Vice is completely intangible and can pass through everything, including his host.
**Energy Attack: Vice can generate black and blue energy to his foot to execute an energy kick.
**Inanimate Possession: Vice can possess inanimate objects via Vistamp application on the said object. He can transform and/or enhance the physical capabilities of these. So far, he has possessed the following:
***Ikki's Bicycle in episode 2. He can also increase the bike's speed to overrun a motorcycle in seconds.
***A rubber duck in both Kamen Rider Revice: The Movie and Episode 49. While possessing the duck, Vice can increase its size and alter the face to resemble his'.
***A maneki-neko in episode 15. He is capable of making it through gold coins as a distraction.
***A power outlet in Kamen Rider Revice: The Mystery. He is capable of entering electronic devices that are plugged in, such as television screens and appear on it as if it was turned on.
***The Rolling Vistamp in Episode 23. By stamping it onto himself, Vice can possess the Vistamp and quickly escape. 
**Mind Accessibility: Vice is able to literally enter the mind of someone else and explore their hidden thoughts and emotions, as long as he is within close proximity of them.
***Memory Erasure: Vice is able to repress any of Ikki's memories that has a traumatic effect on him, such as the fire and Koji Ikeda's injury, though they can be reawakened later on in life either by Ikki himself or Vice manually unlocking them for him. A much more permanent version of this was in effect as a condition of the contract formed between Vice and Ikki: as Ikki continues to fight using the Revice Driver, his memories of his family will eventually fade away, as indicated by Ikki's image disappearing from his family photographs. The erasure was undone when Vice nullified the contract at the cost of his existence and all of Ikki's memories pertaining to him. However, some experience was retained, despite the contract being undone.
**Fire Breath: Vice can breathe fire for offensive purposes.
*Fourth Wall Interaction: Vice is able to interact with the audience, but Ikki cannot and often thinks Vice is talking to himself.
===Abilities===
*Combatant: Vice seems to be knowledgeable in certain martial arts techniques such as executing a corkscrew pile driver. On a more humorous note, Vice sometimes has a knack for executing parodies of techniques from other fictional franchises.
===Weaknesses===
*Ikki Igarashi: Vice is dependent on the body and mind of his host, Ikki, and cannot assume a physical form without Ikki transforming or using the Rex Vistamp. If Ikki dies, Vice will as well. When the two are swapped as a result of using the Rolling Vistamp, George mentioned that Ikki becoming incorporeal meant he could not consume any nutrients and therefore could starve to death, which would kill Vice as well.
===Former Weaknesses===
*Giff: Since Vice is a demon, Giff's revival has also affects Vice, giving him immense headaches that becomes increasingly more painful as Giff grows stronger. Even the Rolling Vistamp, originally intended to alleviate these headaches, couldn't seem to completely negate these effects. Later, Giff's revival caused Vice to go berserk, attacking both friend and foe alike, until the usage of the Thunder Gale Vistamp brought Ikki and Vice in tune together, freeing Vice from Giff's influence. However, Giff can still temporary control Vice, though this was later negated upon Giff's demise.

==Legend Rider Devices==
==Relationships==
===Friends===
*Ikki Igarashi/Kamen Rider Revi: Vice's host, as well as the only human who can sense Vice without using the Revice Driver. Vice has a habit of creating trouble for Ikki no matter what form he takes. In his untransformed state, his unwanted commentary will lead to Ikki angrily retorting, much to the confusion of observers who cannot perceive Vice. Though the two have become close allies throughout their battles against the Deadmans, Vice was visibly hurt when he realized that Ikki still did not fully trust him by keeping him stuck in an incorporeal state outside of transformation. However, after much reflection on Vice's own growth, Ikki decided to place his utmost faith in Vice and fully summon him in his corporeal state, much to Vice's delight. Throughout all battles and life, they became the best "buddies/partners". He loves Ikki for being the best friend he needs.
*Daiji Igarashi/Kamen Rider Live: Vice suspected that Daiji had an inner demon too. When he went inside Daiji's mind, while Kagero took over, he knew Daiji was still in there, as he tells Ikki that there's hope of saving him. 
*Sakura Igarashi/Kamen RIder Jeanne: Vice sensed Sakura had an inner demon too as Lovekov slowly came to life. He even went inside her head to talk to Lovekov.
===Allies===
*George Karizaki/Kamen Rider Demons (III)/Kamen Rider Juuga: As with Ikki, Vice likes toying with and annoying George in various ways, mainly by calling him "Kari-Chan". The latter shows that the feelings are mutual, as he was visibly disgusted when interacting directly with Vice. Additionally, George has gone out of his way to spite Vice through Vistamps, either changing the form Vice takes or outright exclude him from taking one.
*Hiromi Kadota/Kamen Rider Demons (I): Unlike other humans he encountered, Vice respects Hiromi. To a degree doubting Karizaki to use Ikki and Vice like a lab rat just as like what happen to Hiromi.
*Lovekov: Lovekov is Sakura's inner demon, and Vice is the only other one able to interact with her aside from Sakura herself. As a fellow inner demon, Vice takes it upon himself to be Lovekov's "senpai" while he is unable to handle her extreme cuteness.
*Genta Igarashi/Kamen Rider Vail/Kamen Rider Destream: Ikki's father trusts Vice as both he and Ikki make a good team. Vice soon witnesses Genta as a Kamen Rider as both he and Ikki learn of his past life as Junpei and Vail.
*Yukimi Igarashi: After Ikki released Vice when making their contract, he tried to eat her once. This made her scarce of Vice and refuses to accept him around the family. But after proving himself, time and time again, she slowly accepts him as she welcomes him to their dinner table.
*Go Tamaki/Julio/Kamen Rider Over Demons (II): Once enemies, now friends. Both he and Tamaki run the bathhouse together during his fiasco with Ikki fused with him. Unfortunately, the two ended up scaring away the customers. 
*Hana Natsuki/(Kamen Rider) Aguilera: Once enemies, now friends. Vice witnesses Hana become a Kamen Rider, atoning for her sins back as Aguilera.
*Hikaru Ushijima/Kamen Rider Over Demons (I): to be added
*Kagero/Kamen Rider Evil: Daiji's inner demon that controlled his body just to kill Ikki. After being brought back to life by Daiji, Kagero becomes an ally to Vice & the others against Giff.
===Enemies===
*Orteca/Kamen Rider Demons (II): Vice looked inside of Demons realizing Orteca has possession of the belt now. He even senses how his demonic power grew with Demons' power.
*Vail: Genta's inner demon who intends to kill the entire Igarashi family. Vail looks down on Vice for "enslaving" himself under the command of his host, and continuously tempts him to act like a real demon would, thus planting seeds of doubt within Vice regarding his contract and partnership with Ikki. But thanks to a pep talk from Ikki, Vice ignores Vail's words and lets himself be who he is.
*Giff: Giff's slow resurrection caused Vice to get headaches, and even influenced him to rampage as Jack Revice.
*Hideo Akaishi: to be added
*Azuma/Kamen Rider Daimon: to be added
