Kiyoto Maki

is the main antagonist of Kamen Rider OOO. He was a scientist of the Kougami Biotech Laboratory who secretly collaborated with the Greeed and transformed into the after absorbing the purple Core Medals.
==History==
When Maki was a child, he and his older sister, Hitomi Maki lost their parents at an early age. Becoming reliant on Hitomi, Maki was told by her that one's true value is only known when it ends, which became his personal philosophy.
Before the day of her wedding, Hitomi gave Maki her doll Kiyo-chan as a replacement, telling him to use the doll as a means for his poor social skills. On the same night, Maki used candles to start a fire in Hitomi's bedroom which killed her and caused Kiyo-chan's hair to burn off. When she died, the trauma caused Maki to suppress all memories of the event and Hitomi's personality, giving the mental illusion that the fire was an accident and of Hitomi as saint-like figure. It also caused Maki's present desire to see things end.
﻿Maki first appeared in the series during the bomb attacks by Tadano using a water bomb on a car in order to test OOO that would give him a clue about the Same Yummy that appeared every time Tadano developed and used his bombs. After destroying one of the Yummies he introduces himself to Eiji and Ankh explaining his reasons for the water bomb and his affiliation then takes his leave to the Kougami Biotech Labratory. Later he gives Eiji the new Toracandroid while leaving in panic after Eiji caused the puppet on Kiyoto's shoulder to fall off while he was criticizing Maki for not doing anything to stop Tadano or the Same Yummies. Maki appeared again to explain how to control the ToRidevendor properly. Dr. Maki then continues his work and research on OOO after they were all destroyed. He later sets up a partnership with Kazari, ironically becoming the one studied by the Greeed.
When Akira Date became Kamen Rider Birth and moved in with Maki, there were numerous discrepancies between them often getting into comical situations. Around this time when Kougami threatened him to end his partnership with Kazari, Maki's strained relationship with the Greeed led to the creation of the Shachipanda Yummy from the man's unfulfilled desire for maternal affection. Maki himself claimed this was not indicative of his full motives, as affection was a mere desire, while his goal to end the world was instead a sacred mission, something a mere Greeed like Kazari, driven by desire, could not understand. Attempting to deal with his own Yummy using Candroids, Maki was wounded and ended up being taken care of by Chiyoko. Maki took Chiyoko back to his old house, where he revealed to her his story of what had happened - however, being faced with her genuinely kind demeanor caused his mental blocks of his sister's true nature and the origin of the fire to shatter. The result was an abrupt cessation in his desire for affection and a reaffirmation of his belief that the world should be ended, while it could still be remembered as something good and pure. Maki remotely called hundreds of Candroids to himself with the many of the flying ones carrying the painting in his office, and destroyed all of the research data in his office, leaving the Kougami Foundation and joining Kazari and the lost Ankh as a new man in his quest for the world's destruction.
Placing half of the purple Core Medals in his body, Maki gains the ability to create Yummy while keeping a distance away from battles as the purple Medals full power could be invoked if they were in proximity with the purple Medals OOO possessed. But after Ankh is absorbed by Ankh (Lost), Maki takes the opprotunity to take Eiji's purple Core Medals while showing him how much the doctor has gone through the Greeedification process. He later fully mutates into a form known as the Kyouryu Greeed, however to complete the Greeedification, he needs Eiji's Core Medals. After making a deal with Ankh to make him house all the Core Medals, willing to follow his plan if it means completing his own, Maki steals the Core Medals in Kazari's body after he is heavily injured in a fight with Kamen Rider OOO and leaves him to die. He then gives the pilfered Medals to Ankh, and is disappointed when the bird Greeed expresses more ambition than just the desire to be complete, refusing all but Kazari's Medals.
After this, Maki watches as Mezool and Gamel are both subsequently destroyed after being completed, due to Ankh allowing them to have their medals back. He takes their medals after their destruction and leaves. Maki then arrives on a cliff near where Eiji and Ankh are fighting, with Ankh desperately trying to bring Eiji to his senses. Maki adds two more purple Core Medals to Eiji, forcibly making him assume the form of the Eiji Greeed. Ankh fights the Eiji Greeed in his complete form, barely managing to defeat him. Maki advances on the barely conscious Eiji, intending to kill him and take his purple Cores. Ankh fends off Maki by lighting Kiyo-chan on fire, causing Maki to panic. Maki later finds Ankh and attacks him, saying he is no longer fit to be the Core Sarcophagus Uncontrollable that causes the end of the world. Maki not only manages to rip all but 3 of the Medals within Ankh from his body, but also cracks the Taka Medal housing his existence.
Maki then heads to the Kougami Foundation, in an attempt to take Eiji's purple Cores. Maki fights OOO, Birth, and Proto-Birth before Uva arrives. Maki gives Uva the last Batta Medal he needs to be complete, then watches him easily bests the two Births. Maki then witnesses Eiji nearly destroy Uva as the True Tatoba Combo, debating with Kougami over the true purpose of the Medals. 
Saving Uva from destruction, Maki forces him to become the Core Sarcophagus Uncontrollable, planning the death of all life on Earth. Preparing for the final battle, Maki leaves Kiyo-Chan to Chiyoko, then oversees the Core Sarcophagus Uncontrollable convert all matter into Cell Medals while dropping hordes of Kuzu Yummies into the city. 
Soon afterwards, Ankh and Eiji fly up to confront Maki, taking their battle to the ground. In his attempt to absorb Eiji's Cores. Maki is frozen together with Eiji, recieving an empowered Grand of Rage attack from the Medagabryu. Though nearly defeated, Maki is restored by the Core Sarcophagus Uncontrollable, causing Eji's transformation to be canceled.
In desperation, Eiji begins to assume Greeed form, but Ankh intervenes. Combining their power, Eiji and Ankh transform into OOO Tajadol Combo, overwhelming Maki. Retreating inside the Core Sarcophagus Uncontrollable, Maki ambushes OOO with one final attack, only for Ankh to block it away. Eiji and Ankh then immediately activate their Lost Blaze attack. Unable to counter its power, Maki is mortally wounded from the combined might, causing the Purple Core Medals to form a black hole. The black hole absorbs Maki's remains, with Maki noting himself to have been completed. 
In Kamen Rider × Kamen Rider Fourze & OOO: Movie War Mega Max , the black hole created by Maki's death linked a portal into the distant future, causing the absorbed Medals to infect Michal Minato. Though the Purple Core Medals were all destroyed, Maki's lingering evil formed a new Greeed through Michal; the villainous Poseidon.
In Kamen Rider OOO 10th: Core Medal of Resurrection, Maki's Purple Core Medals were not destroyed, with it and all the other "lost" Core Medals obtained by the resurrected Ancient OOO. 
===Kamen Rider Ghost: Legendary! Riders' Souls!===
Maki is resurrected as the Kyouryu Greeed and summoned by Frey alongside Kamen Rider Wiseman after he is revealed to be working with Freya by Takeru Tenkuji and Makoto Fukami, with Frey telling them that he will explain after they have defeated the two adversaries as they transform into Kamen Riders Ghost and Specter. As Fueki takes on Ghost, Maki engages Specter, asking him if he has anyone he cares about. Though Specter refuses to answer, Maki advises that, if he does, he should "put them down" before they grow twisted and ugly, explaining that an ultimate void where nothing exists is the greatest achievement that man can aspire to as he proceeds to grant Specter his worthy ending. Specter defies Maki's philosophy, however, recounting that Takeru taught him to believe in others and how noble it is to protect what they cherish, asserting that he will not give up no matter what happens and that he will push on with his friends at his side who he will never abandon. This grants Specter a trio of Taka Core Medals, from which he unseals the OOO Parka Ghost, creating the OOO Ghost Eyecon which he uses to assume OOO Damashii, granting him the power of Kamen Rider OOO and allowing him to turn the tide against and quickly destroy the Kyouryu Greeed, who concedes that there may still be beauty in the world as he dies again. Shortly after, it was revealed that Maki and the other past enemies were brought back in order for the Kamen Riders to gather the Kamen Rider Ghost Eyecons so they could defeat the monster Xibalba, as Frey and Freya secretly planned together.

==Personality==
Dr. Kiyoto Maki is a mysterious man who holds cleanliness above everything else and has a strong desire for endings, especially for the world. He is intent on studying the O Medals, to the extent of searching for a container of the Core Medals and who should be the one to use the Birth System.
He carries a strange puppet called on his shoulder, using it as a means to communicate with others. Kiyoto is shown to cherish the doll immensely, outfitting it with different wardrobes and accessories. Whenever Kiyo-chan is mishandled, Kiyoto will panic and be unable to speak clearly, especially if the offender uses fire to damage Kiyo-chan.
Kiyoto appears emotionless and has the belief that the worth of one's life can only be verified after they have died, a direct contrast to his boss, Kosei Kougami's love of beginnings. Therefore, Kiyoto will gladly allow another person to die without hesitation, seeing their demise as a joyous thing.
He is also willing to set up partnerships with the Greeed, using them as guinea pigs for his experiments. Initially, Kiyoto desired solely for one of the Greeed to become a rampaging Mega Greeed Out of Control, planning to die alongside every being in existence. Upon gaining the Purple Core Medals though, Kiyoto has changed his mind, deciding to outlive every creature and execute his chosen Greeed once the world is destroyed.
As a child, Kiyoto was obsessively attached to Hitomi, something he subconsciously retained as an adult. From the events that led to his sister's death however, Kiyoto grew delusional, convinced that Hitomi died in an accident. After meeting Chiyoko Shiraishi though, who bears a striking resemblance to his late sister, Kiyoto questions his memories, wondering if his sister was truly a benevolent figure. Receiving visions of Hitomi being cruel to him in his childhood, Kiyoto became more even more unhinged, causing him to decide that everything must be destroyed before the passage of time disfigures it.
In spite of his vile actions though, Maki was not completely a villainous figure, being susceptible to moments of human emotion. As an example, Kiyoto had an odd but genuine friendship with Akira Date, stemming from their shared time together. While ultimately siding against Akira, Kiyoto himself admitted regret to this, to the point of favorably comparing Akira to Hitomi as a companion. Furthermore, possibly as a means for someone else to remember him if his plans failed, Kiyoto entrusted Kiyo-chan to Chiyoko, dressing the doll in the same outfit as himself.
