Complete Monster/Pokémon

Despite its kid-friendly appearance, the Pokémon franchise has been sliding ever further into Darker and Edgier territory with each iteration, both in the main series and in the spinoffs. While Game Freak and The Pokémon Company continue to test how intense a concentration of Nightmare Fuel they can successfully put into each title without compromising its precious E rating, there are times when it shows, as these abominations demonstrate. Note that we used the word "abomination" - calling these folks monsters would insult Pokémon everywhere.

Spinoff Games

 * Pokémon Colosseum features the despicable triumvirate of Evice, Nascour, and Ein, the masterminds behind the Cipher syndicate's conspiracy. Evice, the literally monstrous old man, engineered everything for Cipher (though in the sequel we find out that the syndicate was founded by Greevil, he took mostly a backseat role while Evice was his more involved proxy). Nascour, the demonic looking second in command, kept the other Cipher members in line and oversaw all of their most heinous and underhanded operations, and when faced by Wes at the game's climax, he put him through a succession of battles where Wes' Pokemon weren't even allowed to be healed after each round, all in front of a crowded stadium in order to break his spirit. And worst of all, Mad Scientist Ein developed the process to create Shadow Pokémon: Pokémon artificially powered by a dark force that does something horrific that makes them not only lose their minds but their souls as well, leaving nothing but dark instincts, turning them into heartless, savage fighting machines that can attack and even slaughter people and other Pokémon. This is Cipher's claim to fame, and Ein is continuously trying to improve on the process just to show that he can. He's basically the franchise's answer to Xehanort or Hojo. Cipher is the most abominable organization in the franchise's history, and these three sociopaths blend together into one monstrous leadership: Evice as the heart, Nascour as the muscle, and Ein as the brains.
 * Pokémon XD: Gale of Darkness, the sequel game to the above, gives us Ardos, one of the sons and Co-Dragons of Cipher's leader Greevil, who shows himself to be the most vicious and fanatical member within an already monstrous organization. Ardos is fully involved and supportive of Cipher's worst atrocities, involving the mass corruption of Pokémon into becoming unfeeling Shadow Pokémon—whereupon they'll be rendered unable to be purified and massed into an army through which Cipher will control the world. When Greevil is defeated, Ardos, in a last moment of desperation, attempts to cajole his father into killing the child protagonist by wiping out their base on Citadark Isle—-taking all his subordinates in the building with it, to which Ardos merely scoffs "such things can be replaced". Even in the post-game, Ardos is as dedicated to the Cipher agenda as ever even when his father has surrendered himself, coldly informing the protagonist they are now Ardos's top target in a thinly veiled death threat letter.
 * Classical Darkrai is a well-meaning being with a ghastly self-defense mechanism, but the Pokémon Mystery Dungeon equivalent is a much more sinister beast. He makes Freddy Krueger look smalltime in terms of what he can do to victims in their nightmares, manipulates gods to his whims, orchestrates a Time Crash, makes the future a very miserable time, drops children in eternal nightmares for kicks, and nearly drives the player characters to suicide by tricking them into thinking their existence is threatening the space-time continuum due to Time Travel shenanigans, which is easily one of the darkest moments in the game. He even stoops so low as to torture an innocent child with violent nightmares to lure out the the player characters and make several attempts to assassinate them so he can try his plans again. He has no regrets for his crimes and wishes nothing more than to bring about the complete and utter destruction of the world, just so he can rule the tattered remains in everlasting darkness. His motives were never explained, leaving us to assume that it was For the Evulz. The guy is a vastly darker villain in any Pokémon work even by E or E-10 standards, and the punishment for his misdeeds is much too lenient. Then again, his punishment is implied to be the loss of all his memories (a'la Regal), and this basically forces him to be good.
 * Pokémon Ranger: Guardian Signs gives us Purple Eyes. Before we even learn he exists, he's beaten Rand within an inch of his life and kidnapped both his wife and daughter. Later, he beats the daughter up, too! It gets worse, though; he eventually mugs the elderly Societea members (though, admittedly, they deserve it), hijacks the villain's plans, makes himself immortal, pumps up Mewtwo's power higher than it should ever be, and then commands Mewtwo to finish off Dr. Edward. And when Rand takes the shot for Edward, Purple Eyes is simply amused and continues to attack anyway, even taunting Rand's daughter about her father's endangerment. After the Player Character beats him, he points out that the Sky Fortress is now plummeting and will wipe out all of Oblivia. And then he laughs. He later one-ups himself in the last Extra Mission, in which an enraged Arceus is passing judgment on the human race, he arrives in person. His imprisonment and constant questioning has not redeemed him, but instead turned him into a Misanthrope Supreme who no longer wishes to rule over all humans, but instead Kill All Humans. He begins preaching to Arceus that it should go through with the destruction, but to allow himself to act as its Dragon due to their similar beliefs about humans, which only enrages Arceus more. After Arceus is calmed, it leaves back to its home world and drags Purple Eyes with it to pass judgment on him. Yes, even the god of the Pokémon world deems it unsafe for him to be in our plane. Hastings does say that Arceus will send him back eventually when (or if) he really has a change of heart. However, when you consider that Arceus acted on this but not when Cyrus was unmaking the universe right under it, it says something potent about Purple Eyes' capacity for evil.

Pokémon Anime

 * Diamond and Pearl series:
 * Pokémon Hunter J, as her title implies, hunts rare Pokémon to sell on the black market, and has no qualms with stealing them from other trainers. She is willing to go to any length in order to capture these Pokémon for her clients, including attempted murder on her fellow humans. In her first appearance, she drops a section of her airship containing several of her own men, and the Pokémon that she’d stolen, just in order to be rid of our 10-year-old protagonist, who was in the same section of the ship. She shows absolutely no hesitation or remorse for this action, and Ash had only been a slight inconvenience to her at that point. In her follow-up appearances, she continued to demonstrate her sociopathic, greedy, ruthless nature, as well as her total disregard for any form of life by continuing to steal rare Pokémon, setting fire to a large section of densely populated forest in order to kill Ash, ordering her Salamance to attack humans directly, commanding her Drapion to squeeze the life out of Ash, and abandoning one of her clients to the police the second after she got paid. In her last appearance, she's willing to do a job for Team Galactic, who is planning on wiping out the universe, all for the sake of lining her own pockets. As she’s one of few characters who has proven to be purely evil with no redeeming qualities, J winds up being one of the few anime characters
 * The same series also featured Cyrus, the Big Bad of the Team Galactic arc, as a candidate for this trope. Unlike his game and manga counterparts, who have a few sympathetic qualities present or at least a legitimate Freudian Excuse and possible Heel Face Turn, anime Cyrus is presented as a completely evil villain with no redeeming qualities or excuse for his actions. He wants to exploit the powers of time and space in order to destroy the entire universe and remake it in his own image, and contrary to what he initially claims, he has no intent of sharing it with his followers - he wants everyone and everything to die so that he alone can have his new world. Earlier on when Mars and the Galactic Grunts finished scanning Mt. Coronet in their search for the Spear Pillar, he had Mars utilize a machine which sends out sound waves that cause Steel Pokémon living there agonizing pain and cause them to fly out of control. He then ordered Mars to blow up the still inhabited Iron Island simply because he had no further use for it and to rid himself of Ash and his friends, sporting a Slasher Smile as he did. On top of his extreme Lack of Empathy, he also shows immense hypocrisy by condemning emotions such as rage even while expressing such emotions himself, and attempting to use the time-space powers of the Mind Controlled Dialga and Palkia to kill three kids (Ash, Dawn, and Brock) despite claiming to have a distaste for needless violence and strife.
 * Best Wishes series:
 * The trope actually gets averted with Ghetsis in Best Wishes Season 2: Episode N, who despite still have zero redeeming qualities and actively trying to kill even his own adopted children (while not caring if his own soldiers get caught in the crossfire), his worst actions are entirely implied rather than detailed. For all his screen time, he's pretty standard as far as Big Bad Evil Overlord villains go.

Pokémon Films

 * Dr. Yung, AKA the Mirage Master, from the TV special Pokémon: The Mastermind of Mirage Pokémon was a sociopathic Mad Scientist who specialized in creating Mirage Pokémon because he hated the imperfections of real Pokémon. His experiments were deemed too cruel by his peers (he would forcibly scan a Pokémon's memory to create a new Pokémon), and he was shut down. Vowing revenge, he dons the Mirage Master alter-ego after faking his own abduction, and he also kidnaps Profesor Oak. He tried to emotionally torture him into giving him his password to his PC database in the hopes of hacking into worldwide Pokémon centers. He also abuses, and eventually kills, his Mew Mirage for being a "flawed specimen", and he forcibly scans Pikachu's memory, thus injuring him gravely. After he had finally gotten Oak to crack, he tries to kill him with his newly made Mirages because he was no longer of use to him. Yung later planned on deploying missiles so that he could have a larger field for his Mirages to demonstrate their flawless strength, and he fully intended on releasing Mirage Mewtwo's power unto the world. After he's been defeated, he shows he'd rather die than face justice for his wicked deeds as he walks back into his burning castle before it collapses to a flaming rubble. They Never Found the Body afterwards. Like Vicious before him, Dr. Yung showcased zero humanizing qualities and zero regard for life, artificial or natural.
 * Grings Kodai, the Big Bad of Pokémon Zoroark Master of Illusions. Corrupt Corporate Executive of the Sinnoh Region who owns a network company in Crown City that controls the city's media, he kidnapped mother and child Pokémon from their homeland, imported them into another region, and blackmailed the mother into doing his bidding by threatening to kill the child. All of this is to cause the evacuation of a large city so he can find an energy cluster left behind by time-traveling Pokémon Celebi and absorb it, renewing his ability to see the future, which he acquired twenty years prior at the cost of annihilating the city's plant life. He's willing to destroy the city's ecosystem a second time, and why is he even willing to do this? He's already a wealthy and powerful businessman - he's doing it for more money. But he's got even worse traits than that. He forces Zoroark to allow him to obtain the Time Ripple by electrocuting her child right in front of her to the point that Zorua actually says he thinks he's going to die! Then, to make things worse, Kodai has his Pokémon try to kill Zoroark, since he's got Zorua in the palm of his hand and Zoroark is defenseless so long as he does, this means he does this for no reason except he CAN. He even goes so far as to say that he enjoyed doing it! Later, to gain information about the time ripple, he captures and strangles Celebi to an almost fatal extent before Zorua saves the forest legend. And he manages to one up himself by trying to murder Zorua and Zoroark in cold blood when they trick him, despite the fact that he could've just went on ahead and ignored them to absorb the Time Ripple or flee (the latter of which Vicious and Pokémon Hunter J attempted when they were stopped). And he actually succeeded in killing Zoroark - though Celebi saved her, it doesn't change the fact that Kodai committed, thus far, the only successful cold-blooded murder of a Pokémon (all other times were accidental or just a side effect of what the villain was doing, but Kodai killed Zoroark intentionally, directly in front of the child she was in the middle of being reunited with!). With all that said, his Humiliation Conga (or his Karmic Death in the film's manga adaptation) is immensely satisfying.
 * Chancellor Alva, the Big Bad of Volcanion and the Mechanical Marvel, follows in Kodai's footsteps when it comes to cold-hearted depravity. The prime Cabinet Minster of the Azoth Kingdom, Alva is a cruel, ambitious, scheming man who seeks to usurp control of the kingdom through force. Emotionally exploiting the young prince Rali to the point of brainwashing the boy into being loyal to and dependent on him, and plotting sinister machinations beyond the view of Azoth's rulers, Alva experimented with Neo Arcane Science, a fusion of science and the mystic arts, to devise a technique known as the Mega Wave, which forcefully locks a Pokémon into its Mega Evolution but puts it under mental torture and Mind Rape in the process until it's under Avla's control - pure enslavement of the Pokémon's body and mind. Seeking to exploit the power of the clockwork Pokémon known as Magearna, Alva launches an attack on the Nebel Plateau and tortures Ash and Magearna's friends to force Magearna's compliance in his scheme. Once he has Magearna, Alva tears out its heart, effectively killing it, with the distraught, protesting Prince Rali being Forced to Watch. Alva then has his Mega Gengar put Rali to sleep, planning to dispose of him once he's taken over Azoth. He discards Magearna's body and utilizes it's heart to transform the walls around Azoth into a flying fortress at his command, using it to begin his attack, directly attempting to wipe out all opposition to him and potentially killing some humans and Pokémon populating the Plateau below. When Magearna's lingering spirit keeps his arsenal from firing off, he attempts to break Magearna's spirit by forcing it to obliterate its own home, while it's still aware of it's actions but powerless to stop them. Then when Ash, Volcanion, and the others try to derail his plans, he has them tortured with electric volts again and this time intends on dispatching of them all. Once his plan is ruined, Alva remains defiant and instead locks the fortress so that it's set for a collision into the Plateau itself to obliterate everything and everyone in it's path as an act of spite, while he attempts to escape on a jet pack. By the end, Alva cements himself as an ambitious megalomaniac willing to crush anything and anyone so long as he benefits in the end.

Pokémon Manga

 * Pokémon Special:
 * Sird, the vampiric looking commander in Team Galactic, most likely qualifies. She's first seen working undercover as a member of Team Rocket's Beast Trio in the FireRed/LeafGreen Chapter, and unlike her comrades she is shown to commit atrocities For the Evulz, culminating in her attempting to petrify Deoxys with an attack from her Darkrai only for it to end up hitting the five young dexholders Red, Blue, Green, Yellow, and Silver, turning them to stone. Sird showed no remorse for this and even took satisfaction in it. We later find out that after the Ruby/Sapphire Chapter, she ended up saving Archie and Maxie from certain doom only to make the two men duel to the death for a special armor that grants eternal life to whoever wears it. Archie ended up murdering Maxie for the armor, an act of evil that Sird flat out commended. However, it turned out that if the armor was to be removed, it would drain the life from the one wearing it and kill them, which ended up happening to Archie at the end of the Emerald Chapter. In the Diamond/Pearl Chapter, Sird reveals her fixation on the Poke'Dex, which is so great that she hijacked Charon's Mind Control program to override one Galactic grunt's mind with her own, effectively brainwashing him into doing her bidding and trying to steal a Poke'Dex from Dia, Pearl, or Platinum - an end to which he'd attempt anything, even risking the three kids' lives in the process. If her latter appearances are any indication, Sird is a Hidden Agenda Villain with probable Chronic Backstabbing Disorder. According to Riley, her aura is one of pure malevolence and evil.
 * Ghetsis Harmonia Gropius, Big Bad of the Black/White and Black 2/White 2 Chapters, keeps his original monster credentials and takes them Up to Eleven, making him come off even worse than his gameverse counterpart. As in the games, he is the true leader of Team Plasma and is thus responsible for all the evil committed by Team Plasma. Posing as a kindly and benevolent individual who seeks Pokémon liberation from trainers, he is in truth a habitually sadistic, self serving, narcissistic sociopath who seeks to disarm all trainers and exploit the power Pokémon possess so that he can become ruler of the Unova region and from there Take Over the World. To accomplish this, he raised his son N in an isolated environment and groomed him to be The Hero of legend by giving him a false view of the reality of humans and Pokémon, making him believe his Pokémon friends needed to be freed from the captivity of trainers, but Ghetsis actually planned to enslave all Pokémon for himself, and had no love for N as his son, viewing him only as a usable and ultimately disposable "decoration ornament" for his Evil Plan. He also used Hypnosis to violate other humans' minds and make them release their beloved Pokémon companions, and it's heavily suggested that he's used this on N too in order to obscure conflicting ideas from his mind. Keeping up the demeanor of a well-meaning and courteous preacher even as he's manipulating masses of people into parting ways with their Pokémon companions, having his Eelektross electrocute Black into a near fatal paralysis, and ordering Colress and his loyal servants, the Shadow Triad, to pursue the four Swords Of Justice Pokémon and freeze three of them into a state of deathly petrification, and capturing three other Legendary Pokémon to be used as test subjects, Ghetsis fully reveals his true colors when he has his team attack Unova's League Tournament site and place many spectators in harm's way, capturing six of Unova's Gym Leaders to have them beaten down and tied to crucifixes as a show of his team's power, even getting the one resilient Gym Leader to surrender by threatening the life of an innocent hostage, trying to have his Hydreigon kill Black on the spot and then when some trainers stand against him, ordering to have them all killed to make further examples of them. When he faces Black in battle, Ghetsis attempts to kill the boy in order to keep him silent and conceal the truth of N's defeat from the public by sending out a team of Pokémon specifically trained to counter Black's team so that they cannot protect him and then having Black burned alive by flames created by Hydreigon and brought to life by Volcarona, even stating this would kill Black's Pokémon too! When Ghetsis loses the battle, he uses his associate's Beheeyem to send Black hurled towards Reshiram as it was reverting back to it's dormant state so that Black ends up sealed inside the Light Stone, while he uses Black and White's distress as an opportunity to escape, cruelly mocking them as he does so. Two years later, Ghetsis captures the legendary Kyurem, has it put into a power amplification and extraction device that tortures it and enslaves it's mind, and uses it's freezing power as a destructive Freeze Ray to decimate many cities (including Castelia City, Unova's largest city and home to millions), freezing populated areas solid and endangering countless lives, with many likely perishing in Team Plasma's terrorist attacks. Ghetsis planned to put the entire continent on ice in order to extort total control from it's leaders, and when N and some other young trainers try to stop him, he forcibly uses the DNA Splicers on Kyurem and Zekrom in order to boost Kyurem's power and orders Kyurem to attack his four young opponents directly in an effort to kill them. Prior to Kyurem's fusion, he also had N temporarily caught in the Dark Stone and sealed inside the Inter-Dream Zone to be used along with Zekrom as a Living Battery for Black Kyurem, and then afterwards showed he was perfectly willing to try and kill his own son without shame. Even when Kyurem is freed of it's fusion with Zekrom and fuses with Reshiram instead to fight against Ghetsis, Ghetsis refuses to yield, hoping instead to escape with dozens of stolen Pokémon in their Poke' Balls that could serve as his army for conquering the frozen world. When cornered, Ghetsis opts to self-destruct the Plasma Frigate rather than face justice for his crimes, threatening the lives of every other person and Pokémon on board the Frigate as well, and when N saves his life and admits to the feelings of love and gratitude he still had for his father in spite of every horrible thing he'd done, Ghetsis violently rejects N's efforts to reach him, savagely beating N with his cane in a raving mad homicidal rage against him, unrepentant to the very end. Seeing all Pokémon and fellow humans as tools for his use and thinking so little of their lives that he'd do them harm in a most casual manner with a pleasant grin on his face, Ghetsis was a vile and power-hungry madman who sought to dominate everything in his path and relished all the ways he could make others suffer in the process.
 * In the manga Phantom Thief Pokémon 7, the Big Bad, Team Galactic member Io, is a repellent piece of work. Depicted as a cold, ruthless woman who won't hesitate to eliminate anyone standing between her and what she wants, even her own subordinates, Io showed no loyalty to her organization's cause and sought to Take Over the World by exploiting the powers of the Pokémon Darkrai, whose powers she'd use to ravage the planet and cover it in darkness and then use it's Hypnosis technique to enslave the minds of every living human so that they'd all do her bidding. She's also the one who kidnapped the protagonists' young sister Lily five years ago and brainwashed her into serving Team Galactic. When Lily turns against Team Galactic, Io takes her frustration out of her Number Two by attacking him and calling him worthless before attempting to kill both Lily and her brother. If her treatment of others wasn't bad enough, she's also shown to treat Pokémon as little more than weapons that she can hurt and use to hurt, even forcibly enhancing them to make them serve her purposes better. Thanks to Laser-Guided Karma, she ends up getting Hoist by Her Own Petard when Darkrai breaks free of her control and puts her into a sleep coma with it's Dark Void.
 * Charon of Team Galactic was a money-obsessed Jerkass in the Pokémon games. But his method of introducing himself in Pokémon Diamond and Pearl Adventure is to order his agents to suicide bomb a crowded stadium, which would potentially set fire to the whole town. Of course it fails, but his intent is clear. He holds no regard for the lives of others and plans to control the world with money made from selling legendary Pokémon, as well as extort more money from the masses by threatening them with the powers of Giratina. He also does nasty experiments on Pokémon that put them under a painful form of Mind Control and essentially turns them into Shadow Pokémon that he can use as living weapons even at the expense of the Pokemon's own lives and well-being, Koya's Growlithe being among his victims. This means that whereas the games version of Charon has Team Rocket's mindset, DPA!Charon is every bit as evil and depraved as Cipher. Two of his organization's top officers leave to find the previous leader- Charon tries to kill them, even physically abusing one of them. Which becomes even worse when you find out that said previous leader is being held captive in Charon's base. And as a capper, that previous leader, who goes on to rally the remaining agents against Charon, had previously tried to destroy the UNIVERSE. Thinking only of himself the whole way through, Charon ends the series the sole character to reject The Power of Friendship as a concept and thus ends up as a thoroughly irredeemable individual.
 * In the movie Pokémon: Arceus and the Jewel of Life, Marcus's motivation for killing Arceus is due to a misguided belief that if Arceus leaves with the Jewel of Life, his hometown would be doomed to rot. In the manga adaptation though, he's a completely self-absorbed asshole who wants to steal the jewel in order to become that era's god and wants Arceus dead so he won't interfere with his grand plans. And to that end, he uses his Bronzong to hypnotize Damos to lure Arceus into a trap then have all of his Electric-Type Pokemon electrocute it to death, all of whom he's got under his control via special armor. The initial plan failed and Acreus retaliates by obliterating everyone in the temple, Marcus included, but when the heroes of the present travels to this era to prevent the event from taking place, Marcus decides to manipulate them into helping him and improve on his trap. He would pour Silver Water onto Arceus while his Pokemon would carry out their usual commands. When the heroes learn of this, they tried to warn Marcus that his action will damage the space time continuum, only for him to say he doesn't care, glad even to see that happen as it made him feel like a god, and has his Pokemon and soldiers are set to kill them when they try to stop him. When they manage to foil his plan, he kills himself activating a mechanism when upon death the temple would collapse and kill everyone inside it, meaning his last act would cause the deaths of possibly hundreds (if not more), Pokemon and human alike.
