* ''[[Series/KamenRiderKabuto Kabuto]]'': In the war between the ZECT paramilitary armed forces and the intergalactic invaders known as the Worms, these three show themselves to be the pinnacle of evil in the work:
** [[MilitaryMaverick Masato Mishima]], the second-in-command of ZECT, is, due to his selfish behavior, their TokenEvilTeammate. In the past, Mishima captured the young boy that would become Dark Kabuto and [[PlayingWithSyringes performed horrendous experiments on him]] to unlock the power of the Hyper Zecter, keeping him as a prisoner for years inside a ZECT facility in Area X. Assigned to oversee the development of the Gatack Zecter, Mishima wastes no time in sacrificing the lives of his own soldiers to see who is worthy of its power. Mishima allies himself with the Worms to stop the independent non-ZECT Riders, framing Daisuke for the murder of a rival makeup artist and later sending an agent whom he forced to eat nothing but dry boiled rice for the last seven years of her life to pose as a cadet to get closer to Tendou in a plot to assassinate him. Taking part in the AM Bomb operation, Mishima is disappointed in his superior for attempting to save the civilians that were made hostage by the Worms in Area C3, informing Arata that if he fails the negotiation, he'll just nuke the entire district. After the existence of Worms is announced to the world, Mishima turns himself into a Native and conspires to do the same with the rest of the world by usurping the position of general and, just so he doesn't get to lose his status after all the Worms have been exterminated, manipulating the population into wearing a pendant that detects Worms, but, unbeknownst to them, also converts those wearing it into Natives.
** [[DarkIsEvil Reiji Nogi]]/[[ResurrectiveImmortality Cassis Worm]] is a field leader of the Worms' army who, despite being introduced in the last episodes, proved himself to be the worst of his race. An open cannibal, Nogi follows the philosophy that he must [[TheSocialDarwinist devour the weak]] by absorbing his own subordinates. [[EstablishingCharacterMoment Making his appearance known]] by destroying the peaceful Natives that were being escorted by ZECT, Nogi leads the counterattack against ZECT during the AM Bomb operation and makes the entire Area C3 fall under control of the Worms, promising to execute civilians if ZECT doesn't give the anti-mimicry device to him. With the Worms attacking four different sections of the city at the same time, Nogi directly participates in weakening ZECT's defenses by killing a platoon that was stationed at one of the sites to stop the Worms from continuing their rampage. Going to Shibuya, Nogi brings the Worms to slaughter the soldiers at Area Z, massacring all of those that were guarding the place from him except for the last line of defense, who almost committed mass suicide by nuking the place with them inside to prevent Nogi from stealing the Masked Rider System. After failing to recruit Dark Kabuto to his side, Nogi was ultimately responsible for Tsurugi's SuicideByCop by making him remember that he is a Worm.
** "School's Ghost Story" & "The Dangerous Younger Sister": [[FillerVillain The unnamed principal]] of Jyuka Tendou's high school is a human who willingly collaborates with the Worms all for the sake of pride and fame. Discovering the existence of the Worms after they replaced his choir group, the principal decided to take advantage of their superior abilities by forming a pact with them to replace his own students and make the Worms win at competitions instead of risking to lose with his human students. Sealing the Worms inside an abandoned part of the school that is covered by a mirror, the principal allowed a rumor to spread about the "cursed mirror" that grants the wish of desperate students but also makes them disappear, resulting in an entire basketball team going missing. After Tendou and ZECT uncovered the truth behind the mirror, the principal refused to accept responsibility and [[NeverMyFault blamed the students]] for wanting their wishes granted, telling Tendou that his own sister was the last person to have approached the mirror with a wish, which led to the Worms going after a bus filled with innocent students.

* ''[[Series/KamenRiderKiva Kiva]]'': While the [[OurVampiresAreDifferent Fangire race]] are the major antagonists in the series, there are 4 specific members who crossed the ultimate lines:
** The ruthless [[VampireMonarch King/Bat Fangire]] is the [[BigBad lord of all Fangires]] and original Kamen Rider Dark Kiva, using his position to annihilate the Merman and Franken races and persecute Jiro, the last of the Wolfen. Discovering his wife has fallen in love with Otoya Kurenai, the King tries to force her to kill Otoya, and when she refuses to do so, the King offers the surviving members of the races he meant to exterminate a chance to live if they kill Otoya for him. Transforming them all into [[EmpathicWeapon conscious weapons]] for trying to escape from him, the King captures Otoya and torturously drains him of his life energy to feed his living castle. Threatening the life of [[OffingTheOffspring his own infant son]] to prevent his wife from seeing Otoya again after he escapes, the King's actions [[EvenEvilHasStandards disgust even his most loyal servant]] to the point that he aids Otoya, giving him the power to destroy the King.
** [[SinisterMinister Bishop/Swallowtail Fangire]] is King's calm, psychopathic [[TheDragon right-hand man]]. A [[FantasticRacism firm believer in the superiority of Fangires]], Bishop informed the King of his wife's love for a human, resulting in Maya having her powers taken away from her. Trying to force Mio into embracing her fate as the new Queen, Bishop burns a Fangire in front of her when she refuses to kill him for having loved a human, later telling her that she must kill her LoveInterest if she wants to be a true Queen. Under Taiga's orders, Bishop uses his powers to awaken Wataru's Fangire blood, almost making him murder his own friends. Seeing Mio as a failure, Bishop assassinates her and pins the blame on Wataru, fully intending on leaving him depressed. Proudly confessing his crimes to Taiga, Bishop is kicked out of the Checkmate Four and uses a magical crystal ball to drain the souls of multiple people. Planning on bringing the previous King back, Bishop revives the defeated Fangires and orders them to murder every human they come across, sacrificing his own soul to complete the ritual just so he could become one with the King and "[[OmnicidalManiac destroy everything]]".
** [[PsychopathicManchild Rook/Lion Fangire]] is an excitement-seeking sociopath who murdered Yuri Aso's mother twenty years before the work takes place, leading to Yuri's hatred of Fangires. A genocidal maniac, Rook drove the Wolfen race to near-extinction, leaving Jiro as the sole survivor. To sate his boredom, Rook invents a game in which he must eat a selected group of people within a given amount of time, eating ice cream if he succeeds and punishing himself with electric shocks if he fails. Inventing a new game, Rook decides to do good deeds before getting himself killed, not out of a genuine interest in kindness but merely to keep himself entertained.
** "Unfinished: Daddy Fight" & "Pomp and Circumstance: Thunderstrike Purple Eye": [[KickTheDog Tohru Miyake/Rhinoceros Fangire]] tricks young people into believing he'll help make their dreams come true to lure them in so he can steal their life force. After killing them, he takes an item from them that relates to their dream as a trophy to put in his "Dream Graveyard". His choice of prey is based solely on a love for [[HopeCrusher crushing the dreams]] of young people and nothing else. Even [[TheHero Wataru]], who had generally tried to find the good in everyone, even Fangires, found his actions unforgivable.

[[folder:Heisei Phase 2 Series]]

* ''[[Series/KamenRiderBuild Build]]'': In this tale of creation versus destruction that stands as possibly the [[DarkerAndEdgier/KamenRider darkest series]] of the Heisei era, this duo are the most vile:
** [[Characters/KamenRiderBuildBloodStalk Evolt/Kamen Rider Evol]], the true mastermind behind the problems faced by the heroes, is an entity seeking to create a "new world" by [[PlanetEater devouring everything in the universe]], leaving only himself. Destroying planets alongside his people, the [[PlanetLooters Blood Tribe]], Evolt wiped out many civilizations before being stopped on Mars by the surviving Martian Queen Vernage. Possessing an astronaut and rendering him [[AndIMustScream aware but unable to do anything]], Evolt goes to the Earth and causes the Skywall Disaster that killed countless innocents and split Japan into three states. Under the alias "Blood Stalk", Evolt corrupts Gentoku Himuro by preying on his mind and killing his best friend and founds [[Characters/KamenRiderBuildFaust Faust]] with him and scientist Takumi Katsuragi to carry out painful experiments on kidnapped people to turn them into [[MonsterOfTheWeek Smash]]. When Katsuragi discovers his alien origins and turns against him, Evolt mind wipes him, kills an innocent man to swap his face with him, and renames him "[[Characters/KamenRiderBuildSentoKiryu Sento Kiryu]]" so he can keep using him. Desiring Ryuga Banjo, whom he corrupted with his DNA when he was only an infant, as his new host, Evolt had Ryuga's fiancée fatally transformed into a Smash to raise Ryuga's Hazard Level by increasing his rage. Inciting a war between the three states of Japan, Evolt painfully experiments on Gentoku to turn him into a weapon and takes over Sento's body, keeping his personality around so he can [[ForcedToWatch make him watch]] as he slaughters his friends. He later challenges the Kamen Riders to a final battle where they will have to reach the top of the Pandora Tower, destroying a section of Japan for every ten minutes they don't make it. Achieving his ultimate form, Evolt summons a [[UnrealisticBlackHole Black Hole]] to consume the Earth but destroys it slowly [[ForTheEvulz so he can gaze at the despair on the heroes' faces for longer]].
** [[CorruptCorporateExecutive Juzaburo Namba]] is the greedy CEO of [[Characters/KamenRiderBuildNambaHeavyIndustries Namba Heavy Industries]] and [[Characters/KamenRiderBuildBloodStalk Evolt's]] collaborator. Profiting off the Skywall Incident, Namba was responsible for converting children into his brainwashed, suicidal ChildSoldiers and turning Seito into his PuppetState. Taking part in the creation of Faust, Namba sponsored the criminal organization with the intention of sparking a conflict between the nations to [[WarForFunAndProfit fill his pockets]]. Planning on making a weapon stronger than a nuke with the Pandora Box's energy to sell to the highest bidder, Namba tortures the mentally-broken Gentoku Himuro until he is ready to become his own Kamen Rider, implanting a chip in his body that would kill him if he disobeyed his orders. Deciding to reunify Japan into a world superpower under his law to give birth to an "immortal Namba empire", Namba engineers a massive and destructive MilitaryCoup to conquer the country and [[TakeOverTheWorld the world]], starting by taking Prime Minister Tajimi into custody, assassinating Prime Minister Mido and then sending his troops to invade Touto to be assimilated by force. Side material expands even more on his atrocities, as he had imprisoned Gentoku in an annexed [[POWCamp concentration camp]] for failed Faust experiments, a place where he was regularly beaten, and in one occasion, suffered an [[PrisonRape attempted rape at the hands of another prisoner]]. At some point, Namba had employed [[MadScientist Kaisei Mogami]] and allowed him to work on the Enigma, indirectly killing even more people and almost causing the destruction of two worlds.
