''Series/TwentyFour'' does not lack [[CompleteMonster this trope]].

----
* Recurring villain Nina Myers (seasons 1-3). While terrorists have the excuse of being motivated by ideology, Nina is driven by her bottomless {{greed}}. Having infiltrated CTU, Nina fed information to the Drazen terrorists to assist in their schemes, and when [[TheHero Jack's]] wife Teri Bauer overhears Nina speaking German, Nina murders her to keep Teri from connecting her to Germany. Nina assists in numerous innocent deaths and terrorist activities, even conspiring to allow terrorists to get their hands on nerve gas. Jack Bauer once summed it up best: "You're worse than a traitor, Nina. You don't even have an ideology. You don't believe in anything."
* Ramon Salazar from season 3 was a brutal psychopath of a drug dealer. Since his release from prison, Ramon killed numerous innocent people. Ramon was attempting to get his hands on a lethal bioweapon called the Cordilla virus for his own profit and when his own brother Hector caused problems for the deal, Ramon cold-bloodedly gunned Hector down, simply for a better payout for the Cordilla.
* [[BaldOfEvil Abu Fayed]] from season 6 stands out as having one of the highest body counts on the show. He is responsible for orchestrating dozens of suicide bombings across America, as well as torturing Jack Bauer and selling out his former partner, Hamri Al-Assad, after Assad betrayed him and his cause. After Fayed convinces the government to release one hundred prisoners, Fayed uses one of the prisoners to arm a nuclear bomb, which is later detonated, killing at least 12,000 civilians in the Los Angeles area. He later captures and tortures Morris O'Brian [[ThisIsADrill with a drill]] until Morris breaks and creates a triggering device for the nukes, one of which Fayed activates. [[BigBadDuumvirate With the help of Dmitri Gredenko]], he conspires to set off the remaining nukes across America. After his plans fail and Fayed is captured, Fayed escapes and attempts to set off the final two nukes in downtown Los Angeles.
* [[TheChessmaster Phillip Bauer]], also from season 6, was Jack's [[ArchnemesisDad father]] and a CorruptCorporateExecutive who helped mastermind a conspiracy that reached all the way to the President and nearly started WorldWarIII. Phillip helped have a previous president assassinated as part of this conspiracy, and multiple innocents died thanks to his actions, which. To cover his tracks Phillip [[OffingTheOffspring murders his co-conspirator younger son]] Graem, and later sells out his country upon being discovered, annoyed at the lack of appreciation for his work. Phillip kidnapped his grandson, fully willing to [[WouldHurtAChild kill him]] if the boy didn't conform to Phillip's standards of his legacy.
* From the film ''Redemption'' and the seventh season, there's [[ScaryBlackMan General Benjamin Juma]] of the fictional African nation Sangala. Prior to the events of ''Redemption'', Juma engineered a coup that placed him in a position to kill thousands of Sangalans in a brutal genocide. When deposed, Juma was contacted by an [[NebulousCriminalConspiracy American conspiracy]] which offered to return Juma to power in return for being allowed to use Sangals to develop bio-weapons. Juma had the weapons tested on a civilian village, which he then had firebombed to conceal the evidence. When preparing to launch a vicious assault on Sangala's capital, Juma conscripted {{child soldier}}s and had them brainwashed. In season 7, Juma sends his right-hand man [[TheDragon Colonel Iké Dubaku]] to the US for a series of terrorist attacks and murders and then [[YouHaveOutlivedYourUsefulness has Dubaku killed]] when he is captured, to make sure [[HeKnowsTooMuch Dubaku won't reveal anything]]. Juma personally leads a paramilitary strike that captures the White House where he takes and kills hostages to show how serious he is. When he realizes his plans are foiled, Juma orders the hostages murdered and attempts to get to the President to murder her himself.
* Cheng Zhi has one of the best claims to be [[TheHero Jack Bauer's]] ArchEnemy. Originally the head of security of the Chinese consulate, Cheng subjected Jack to [[ColdBloodedTorture horrible torture]] after capturing him at the end of Day 5. Originally a loyal soldier for China, Cheng [[ItsAllAboutMe began to think only of himself and his own advancement]]. Cheng subjected Jack's former girlfriend Audrey Raines to a [[MindRape near-lobotomy]] which left her damaged for a long time after. After being thought dead, Cheng resurfaces in ''[[Series/TwentyFourLiveAnotherDay Live Another Day]]'', having been the one responsible for Margot Al-Harazi getting the override key for attack drones. Manipulating events (and eventually having a [[spoiler: sniper kill Audrey]]), Cheng tried to launch a nuclear missile to begin WorldWarIII between China and America where millions would die out of petty vengeance for China abandoning him for his criminal actions.
