Complete Monster/Dragon Ball

""I doubt I need an introduction, but just in case, I am the mighty Lord Frieza... and yes, all the horrible stories you've heard are true." - Frieza, Dragon Ball Z"

Dragon Ball is the Trope Codifier for modern shonen action series, including its villains. Most of them are Card-Carrying Villains who do things out of the heck of it, but not too evil. And there are some who were created evil and do some questionable things. Then there are the few who are so twisted that they are memorable for being so ungodly demented and cruel and lacking the morals/mercy of their fellow villains who are either horrified and can't do anything about it or actually admire them due to their overwhelming power.

Anime & Manga

 * Frieza has more than earned the moniker of being the franchise's most evil villain. Not only was he racist and prone to killing his own henchmen for either failing him or being of no further use to him, but he was also responsible for the genocide of the Saiyans and destruction of their home planet (a horrific act not because of the evil Saiyans dying, but because the Saiyans were nothing but loyal to Frieza), since he feared that he would be overthrown by the fabled "Super Saiyan of Legend". During his invasion of Namek, he killed many civilians and several warriors, even after he got their Dragon Balls. Not only that, he tortured Nail, Gohan, and Vegeta to near-death, and even had Vegeta crying and begging Goku to stop Frieza before dying from the fatal wound Frieza gave him. He also turned Dende into a smoldering corpse, blew a hole through Piccolo's torso, murdered Krillin and threatened to do the same to Gohan, which led to Goku becoming the very thing that he feared most. When Goku gives an almost-dead Frieza enough energy to escape the exploding planet, he uses that little bit of energy to attack Goku from behind in hopes of killing him. He only survives this due to getting rebuilt into a cyborg by his father King Cold, and then demands he, his father and his entire fleet head to Earth just so they can kill all of Goku's friends and then kill Goku himself after he's been made to suffer enough. Instead, he gets unceremoniously killed by Future Trunks. Genocidal, arrogant, and sadistic beneath his polite exterior, Frieza set a new standard for evil in the series.
 * And all of it was done willingly. He wasn't born to be a monster (like Cell or Majin Buu) or insane (like Broly and some of the other movie villains), at least, not at first glance. He simply delighted in making others suffer. He obviously had enough funds to live a life of permanent luxury, but instead founded a company whose business was finding populated worlds, depopulating them, and then selling them to the highest bidder. And then once he found no more use for his primary employees and felt they could grow to rival or even surpass him in power, he went and executed the most devastating Finger-Poke of Doom in history - wiping out thousands if not millions of loyal soldiers, including an entire race and planet of them, save for a few who weren't on home base at the time, with a giant sun bomb generated and released from one finger - while sitting in his hover-chair, laughing maniacally and telling his top lieutenants to watch the "pretty little fireworks".
 * There's also how he acts during fights. With the exception of King Vegeta and Bardock, who he simply killed on the spot due to time constraints, he tortures anyone brave (or stupid) enough to fight him. Nail (who got both of his arms RIPPED CLEAN OFF), Krillin (who was savagely impaled by Frieza in his second form), Gohan (yes, even a five-year-old child, by slowly crushing his skull and LAUGHING AT HIS SCREAMS), Piccolo (with whom Frieza played paintball with, just remove the "t"), Vegeta (who arguably got the worst of them all, ultimately leaving him crying in excruciating physical and mental agony after Frieza continuously beat on his spine and drove a rock through his chest), and Goku (the ONLY one able to fully return the favour) were all beaten up in extremely painful ways simply because Frieza was able to do so without fear of interference.
 * He's still a sadistic monster in Dragon Ball Z: Resurrection ‘F’ (both the film and the saga adapted from it in Dragon Ball Super), which takes place years after his death. Resurrected by his underlings Sorbet and Tagoma, he craves revenge on the Saiyans and will stop at nothing to achieve it. After Tagoma suggested that Frieza should just ignore the Saiyans and focus on saving his crumbling empire, Frieza killed him by blasting him out into space (or, going by the Super adaptation, kept him alive to routinely torture as the target of his special training, which ended up mentally breaking Tagoma and turned him into a merciless, cold-hearted psychopath just like Frieza). He started an invasion of Earth and destroyed an entire city with one blast just to make his presence known. In addition to beating Gohan to within an inch of his life (and, in the Super adaptation, finishing what he started on Planet Namek by killing Piccolo with a Full-Power Death Beam through his chest), he killed his entire army, except for Sorbet, after they lost to the Z-Fighters, regarding them all as disgraces unfit to wear his empire's uniforms. After Goku was blasted with a laser by Sorbet, Frieza tortured him by stomping on his chest and attempted to choke the life out of him. When he was then overpowered by Super Saiyan Blue Vegeta, he destroyed the Earth with a Suicide Attack, just so he could spite Goku one last time. Fortunately, Goku is sent back three minutes in time by Whis and vaporizes Frieza with a God Kamehameha. We also see what Frieza's own personal Hell is like at the beginning and end of the film - a beautiful field of flowers where cherubs, fairies, sentient stuffed animals and angels in bunny costumes are all living and playing happily while he's in a cocoon tied to a tree, endlessly screaming his head off at the fact that he's unable to hurt anyone there.
 * During the Universe Survival Saga, Goku visits Frieza's personal Hell and makes a deal with the tyrant that, in exchange for Frieza fighting for Universe 7 in the Tournament of Power (to prevent the universe from being erased) he'll revive Frieza with the Dragon Balls. Frieza agrees, only to attempt to make the same deal with Universe 9's God of Destruction, Sidra to erase his own universe simply to save his own skin. Frieza does end up fighting for Universe 7 in the tournament and even plays a part in helping them win, but the whole way through, he's thinking only of preserving his own existence so that he can wish upon the Super Dragon Balls and become powerful enough to reign over the gods themselves. Having learned the value of Pragmatic Villainy, instead of immediately seeking revenge on Goku and his friends, Frieza takes this opportunity to retreat back into space and rebuild his empire, announcing that "the Emperor of the Universe has returned!".
 * While Dragon Ball Super: Broly tones down his heinousness in favour of having him be more comedic and out of focus, he still has scenes and acts in the film that still show how much of a monster he is. When King Cold retired and handed Frieza the reins to the Planet Trade Organization, Frieza's first order of business is to give the Saiyans (who, at the time, could not use energy projection and relied on outdated weapons and tech) scouters and, to demonstrate their effectiveness, locates and gleefully kills a group of Saiyan snipers who were trying to assassinate him. In the present day, he recruits Paragus and his son Broly, testing the latter's power by making him fight Goku and Vegeta. He then murders Paragus and promptly lies to Broly, saying that he was killed by a stray ki blast (thus essentially implying that either Goku or Vegeta killed Paragus, or worse, akin to Scar in The Lion King, leading Broly to believe he accidentally killed his own father), causing the gentle yet mentally unstable Saiyan to transform into the Legendary Super Saiyan and go on a murderous rampage. After his underlings Cheelai and Lemo pull a Heel Face Turn and use the Dragon Balls to save Broly from being killed by, Frieza nonchalantly reveals that he's been planning to turn Broly into his right-hand man so that he can use him as his ultimate weapon to finally kill Goku and Vegeta.
 * Cell, an android lifeform created by Dr. Gero, is introduced going around towns claiming victims like a Serial Killer, eating people with his tail and absorbing their life energy just to increase his own power. He later nearly kills Piccolo by blasting through him and attempting to stop his heart, then absorbs Androids 17 and 18, which results in him reaching his perfect form (with the last being disturbingly prolonged in order to give the latter absolute fear of being absorbed, well after he'd played horrible mind games with her as well). And, though programmed to kill, he has a sadistic pleasure in it that is all his own doing: he starts his own fighting tournament, the "Cell Games", just to hold off destroying Earth so that he can "see everyone's faces contort in terror" and states that he would've hunted every single person on Earth one by one before blowing up the planet if he won. During the Cell Games, he beats Gohan to near-death and creates a bunch of "Cell Juniors" to torture the other Z-Fighters so that he can transform to his Super-Powered Evil Side, which he succeeds at by cruelly destroying Android 16 in front of him. Unlike most of the series' villains, he succeeds in killing Goku (although that wasn't what he intended, as it came about as a Heroic Sacrifice to save Earth). And then when he comes back from the self-destruction, he blows Future Trunks in half and gravely injures both Vegeta and Gohan. As he readies to wipe out all his opponents, Cell declares that it must be his destiny to keep getting stronger so that he can spend an eternity using his power to toy with the weaker beings on all other worlds in the universe, and then destroying them all the same way he was planning to destroy Earth. Having inherited Frieza's knack for being a merciless sadist in the cells, along with Vegeta's Pride, Cell was one of the Z-Fighters' most malevolent adversaries.
 * Broly,He is one of the few surviving Saiyans after and evil tyrant named Frieza destroyed their home world. Broly and his father Paragus survived and traveled across the galaxy bringing nothing but destruction. They arive at Earth and meet Goku, Vegeta, and the other Z fighters. Broly remembers Goku and remembers how Goku crying irritated him which caused Broly to hate him. Broly ultimately decided to destroy Earth and the Z Fighters attempt to stop him. Broly proves to be a very powerful and capable fighter and the heroes have much trouble fighting him. Not even Goku, Vegeta, and Trunks's Saiyan Transformations prove helpful as Broly can become a Super Saiyan himself and he's eventually pushed into his own original Super Saiyan Transformation: Legendary Super Saiyan. After Broly kills his own father, he creates a giant energy blast that will destroy the planet. Gohan, Piccolo, Trunks, and eventually Vegeta share their energy with Goku and he uses the power and punches Broly in the chest sending him into his own energy bomb, the day being saved. Years later, Broly awakens from his defeat in an iceberg. He fights with an older Gohan, Gohan's brother Goten, present Trunks, and Videl. But Gohan and Goten combine their Kamehameha attacks, which is further powered up by Goku's spirit not unlike how Goku powered up Gohan's Kamehameha to defeat Cell, and Broly is defeated once again. Scientists revive Broly in a lab, now being known as Bio-Broly. Goten and Trunks investigate and submerge Bio-Broly in water, which turns him into stone. Goten and Trunks combine their Kamehameha and destroy Broly once and for all.


 * Babidi also qualifies. Not only does he orchestrate the revival of Majin Buu, ultimately making him the one responsible for all the death and destruction that occurs later, but in addition, he kills off Spopovich and Yamu, who actually succeeded in their task for him, just because he didn't need them anymore (and then comments on how enjoyable their deaths were). Then he throws Dabura, his loyal right-hand man who came up with the idea of reviving Buu, under the bus in the same fashion once the Majin is successfully revived. Not to mention the fact that he took great delight in having Buu systematically kill the people of Earth so he could lure out Piccolo, Goten and Trunks all for the purpose of getting his petty revenge against them. And when he's asked to stop this by Goku, he then announces that he'll have more people killed just to spite him. Finally, he blows up the head of someone who gave him the names of Piccolo, Goten and Trunks, just because he found the information to be useless. He also constantly threatens and abuses Majin Buu when the latter doesn't obey him, which later results in Buu punching Babidi's head off before vaporizing his body. He's up there with Frieza in terms of just being an evil asshole that doesn't have the excuse of being a creation born evil or insane.
 * Super Buu. While Kid Buu and Fat Buu don't really count, the former being nothing more than a rampaging animal and the latter being too dumb to know any better, Super Buu has the evil of Kid Buu with the ability to understand (and not care) about his own evil. This is a being who, once made eloquently intelligent by absorbing Piccolo, actually lamented killing off all of humanity because destroying their cities wasn't as fun without hearing the terrified screams of his victims, and believe me, he's not exaggerating when he said this. When told by Piccolo to go off and kill some humans so that Goten and Trunks would have enough time to master the Fusion Dance, his response is to fire a barrage of ki blasts that locks onto and kills every single living being on Earth (except for Mr. Satan, Bee the Dog, Tien Shinhan, Chiaotzu, Android 17 and everyone on both Korin's Tower and Kami's Lookout). He also turns Chi-Chi into an egg and crushes her to death in front of Goten just for slapping him across the face. After losing his temper during a fight with Gotenks and Piccolo, he turns Krillin, Videl, Bulma and everyone else on Kami's Lookout into chocolate and eats them alive. After he absorbs Gotenks and Piccolo, he proceeds to beat Ultimate Gohan senseless while using Piccolo's teachings to mess with his head. Absorbing Gohan as well, Super Buu declares that he will use his god-like powers to enjoy systematically wiping out every single being in the universe, living or dead. Becoming enraged after he's unable to overpower and/or outsmart Vegetto, Super Buu decides to destroy the very fabric of reality itself, threatening the stability of the multiverse. A callous sadist, Super Buu would happily snuff out all sentient life just so he could spite Vegetto for beating him in a fight.
 * Zamasu in Dragon Ball Super is a former Kai from Universe 10 and apprentice to the Supreme Kai Gowasu who has a strong hatred towards mortals because they keep making the same mistakes. Once Goku shows a power capable of rivaling the gods, he decides that mortals are too dangerous to continue living. He failed to recognize his own similar faults, thinking himself to be a pure and divine deliverer of justice upon the realms of gods and mortals. Eventually falling into villainy, Zamasu plans to eradicate all mortals in the multiverse, with a scheme that he calls the "Zero Mortals Plan". To enact this plan, Zamasu murders his own mentor Gowasu, stealing the potara earrings to usurp his status as a Supreme Kai, and the time ring to travel through timelines. Then, he travels to another timeline to collect the Super Dragon Balls, switches his body with Goku's and kills him right in front of Chi-Chi and Goten… before decapitating them both with a ki blade just because they got in his way. Knowing that no one would be willing to help him for his plan, Zamasu (as Goku Black) then formed an alliance with his future self. Together, they proceed to travel to Future Trunks' timeline to destroy the Super Dragon Balls so that there is no way to reverse their plan, slaughter all the gods to keep them from interfering and slowly reduce humanity to near-extinction. Upon fusing with his future incarnation, Zamasu proceeds to cause mass destruction on Earth just to demonstrate his power as the "ultimate god". And when Trunks managed to destroy his physical body, Merged Zamasu's spirit survives through his sheer hatred of mortals and attempts to exterminate all life throughout the multiverse by merging with it, extending the effect on the other timelines, with the only way of stopping him being Lord Zeno eradicating the future timeline entirely, completely destroying Merged Zamasu for good. In all of his incarnations, Zamasu is a petty, hypocritical and sadistic narcissist who thinks that all of reality should be reshaped in his own vision and his distorted ideals of "justice", based entirely around the idea of purging the multiverse of everyone and everything that he hates.
 * The most horrifying part about Zamasu is that he is a Supreme Kai, one of the gods of the universe - the people normally expected to play the role of Big Good. Even Frieza was at least born into a family of galactic conquerors and raised to follow in his father's footsteps and then some, but Zamasu has no such troubles in his background. Gowasu looked after him like a father would, and there's no indication of Zamasu having suffered any mistreatment from any of the other gods. There was nothing there to make Zamasu go bad except for him being The Sociopath, yet not only did he choose to go bad, but he chose to become the worst of the worst - to do the most unspeakable acts of evil to both mortals and gods alike, all because they didn't match up to the standards of goodness and justice as defined by him. He wanted to exterminate all that could not be subjugated to the power of the divine laws he fanatically followed, worshipped and enforced, and when his hate for all living creatures who were not himself grew so great, he instead opted to just end everything so that only he would have the gift of existence. In short, Zamasu, through sheer hatefulness and Pride, became even more despicable and more heinous than Frieza, Cell, Super Buu and every other villain in the franchise (except for Demon God Demigra, who shares Zamasu's multiversal ruination tendencies).
 * His pettiness is cranked Up to Eleven in the manga, where he doesn't even meet Goku at first. He just sees his fight with Hit on GodTube and becomes salty about his Super Saiyan Blue form, feeling it blasphemous that a mortal Saiyan should achieve god-like power, making the reasoning for his spiral into villainy even more ridiculous.
 * Moro, the "Eater of Worlds", is an evil sorcerer who eradicated all life on 320 planets ten million years ago, consuming the souls of his victims in order to empower himself. Escaping from the Galactic Patrol Prison with help from a former Freeza Force soldier, Moro attacks New Namek, murdering Grand Elder Moori and most of the Namekians so that he can steal the planet's Dragon Balls in order to restore himself to his prime. After freeing all of the Galactic Patrol's prisoners, Moro goes on a murderous rampage across Universe 7, destroying numerous planets and devouring their life energy to further empower himself. Staging a planet-wide invasion of Earth, Moro kills off most of his fellow prisoners for getting in his way before subjecting the Z-Fighters to a brutal Curb Stomp Battle that is only stopped by Agent Merus's Heroic Sacrifice. When Goku unlocks Perfected Ultra Instinct and pushes him to the brink of death, Moro fuses with the Earth itself and turns his own body into a ticking time-bomb, knowing that if Goku kills him, the resulting explosion will not only obliterate the planet, but the entire Northern Galaxy as well.

Video Games

 * Frieza is the Villain Protagonist of the first Budokai game's What If? story "Raging Frieza" & "The True Ruler". He becomes enraged when he's beaten to the Dragon Balls and thus can't become immortal, and fights the heroes. In succession, he defeats and kills Gohan, Piccolo and - after powering up - Vegeta and Goku. Sighting the dragon Porunga, he successfully wishes for eternal life then blows up Namek, after which he flies to Earth, planning to destroy it as well, cackling maniacally all the way.
 * Dragon Ball Z: Supersonic Warriors video game duology:
 * Cell commits many more crimes throughout various routes of these games. During his story in the first game, when Dr. Gero tells Cell that they'll revive the Red Ribbon Army, Cell refuses and remorselessly kills his creator when it results in a fight. After killing Gohan and the rest of the Z-Fighters, Cell creates countless Cell Juniors to hunt down and kill every last person on Earth while he goes to sleep. When Cell defeats Majin Buu, he decides he has no further use for Earth and destroys the solar system, going on to terrorize the rest of the universe in search of another fighter to give him a challenge. During one of his routes in the sequel, while waiting for the Cell Games to begin, Cell kills Future Trunks and takes his time machine for the sake of fighting and killing an alternate version of himself. In another route, enraged by Goku giving up during their fight in the Cell Games, Cell breaks his own rules and destroys the Earth anyway. During one of Piccolo's routes, Cell goes to Namek in an attempt to revive the destroyed Android 18 for the purpose of absorbing her. While there, he makes a deal with Cooler that he'll help Cooler terrorize Namek in search for the Dragon Balls, secretly planning on killing Cooler when they're all gathered.
 * Cooler himself also proves to be just as bad as his original counterpart, if not moreso. Upon hearing that his younger brother Frieza was killed by a Super Saiyan, Cooler, angered by this blow to his family's pride, ravages a city in hopes of drawing out Goku. In one of his routes, after successfully killing Goku, he terrorizes Earth for years on end, slowly hunting down and purging every city for his own amusement. When he discovers that Frieza has been feeding Gohan and Trunks information, Cooler kills his brother despite saying he'd spare him if he swears loyalty, before moving on to betray King Cold in an attempt to take over the Planet Trade Organization. In one of Piccolo's routes, Cooler and his men attack Namek in search of the Namekian Dragon Balls, threatening to wipe out all of the Namekians if they don't cooperate. In one of Frieza's routes, Cooler uses the Big Gete Star to consume several planets to add to his power behind the family's back. After consuming Namek, he reveals that he intends to kill both Frieza and King Cold, and use the Big Gete Star to consume all planets in the universe.
 * Frieza and Cell both prove to be just as monstrous as they are in canon in Dragon Ball Fusions. When Frieza is freed from hell by Tekka and his team, Frieza orders the Ginyu Force to kill them for no reason. When Tekka's team comes across Cell, Cell immediately tries to kill the group to lure out Goku for the purpose of fighting him. Later, the heroes find out that Frieza and Cell have joined Pinich's team for the purpose of manipulating him into performing the Ultra Fusion. Frieza and Cell then take over the fusion before attempting to destroy the Timespace Rift and everybody in it as Ultra Pinich, only being stopped thanks to the timely intervention of Beerus and Whis. The two then flee, opening up a portal to Hell to create more chaos. They later escape to the real world in an attempt to destroy the entire galaxy.
 * Demon God Demigra of Dragonball Xenoverse was once a Supreme Kai who fell from grace and became a demonic Evil Sorcerer. After growing powerful enough to be considered a god and attempting to control all time and space in the multiverse so that he could have an eternal reign, he was imprisoned within a crack in time by Chronoa, the Supreme Kai of Time. To free himself, he sends out an image capable of acting on the physical plane to cause chaos and distort time, often working his dark magic through the actions of his Unwitting Pawns, Towa and Mira. One of the timelines has him brainwashing Piccolo into killing Goten and Trunks, causing an enraged Super Buu to blow up the Earth. Another has him trying to brainwash Beerus into killing Goku and destroying Earth. After his release, he brainwashes Xeno Trunks into trying to kill the Time Patroller and plans to destroy the Nest of Time, in essence destroying all of time itself, so that he can then destroy the entire multiverse and reshape it so that everything revolves around him.
 * Xeno Goku Black from Super Dragon Ball Heroes is an alternate version of Zamasu who learned of his eventual demise from the "Dark King of Fear", Fu. Enraged by this revelation, Xeno Black travelled across various timelines and killed the Goku in every one in order to fully master his stolen body. By the time he appears in Fu's artificial universe, Xeno Black has murdered ninety-nine alternate Gokus and gleefully boasts to the Goku from the main timeline that he would be his one-hundredth victim. When he's pushed to the brink of defeat by Goku using Ultra Instinct "Omen", Xeno Black destroys the artificial universe's Planet Vegeta in a last-ditch attempt to kill his enemies, murdering Turles when the evil Saiyan betrays Xeno Black and allows the heroes to escape. Xeno Black later reveals his goal of continuing his main timeline counterpart's "Zero Mortals Plan" by using the energy accumulated within Fu's artificial universe to create "artificial mortals", whose life energies would be linked with those of the mortals of Universe 7. By killing all of these "artificial mortals", Xeno Black would be able to exterminate every mortal in Universe 7 without fear of reprisal from Lord Zeno. Just as depraved as his other incarnations, Xeno Black was more than willing to wipe out all mortal life in Universe 7 so he could fulfil his own twisted vision of "justice".

Movies

 * Dragonball Evolution: The film's version of King Piccolo is an evil Namekian who attacked Earth alongside the fearsome monster known as Oozaru, bringing the human race to the brink of annihilation before he was sealed away by seven mystics. Returning 2,000 years later, Piccolo decides to seek out the seven Dragon Balls with the intention of wishing for eternal life, and then eliminating the human race in revenge for his imprisonment, beginning his search by destroying a village filled with innocent people. Piccolo would then attack Goku's grandfather, Gohan, in his home, before killing him by crushing him with the house's rubble. After Goku and his friends manage to retrieve the Dragon Balls, Piccolo has his servant Mai steal them, nearly killing Goku in the process. When Goku transforms into Oozaru during his final confrontation with Piccolo, the latter has Goku attack his own friends, while also having him strangle Master Roshi to death before he could re-seal Piccolo. When Goku regains his senses and fights back, Piccolo vows that he'll destroy the planet just to spite him.
