- Batman: The Animated Series: The Joker is Batman's Arch-Enemy. Before becoming a Monster Clown, the Joker was a mobster and hitman who murdered Andrea Beaumont's father, Carl, over money owed to the latter's employers; a murder he committed even after the debt was repaid. This set in motion Andrea becoming the supervillain Phantasm and took away Batman's one chance of a normal, happy life. Following his transformation into the utterly psychotic Joker, he now commits crimes more often for fun than he does for any profit. Samples of his crimes include repeatedly abusing his girlfriend Harley Quinn; trying to bomb a child's birthday party; setting up Catwoman to go through a grinder; psychologically tormenting Charles "Charlie" Collins for two years, before using him in a scheme to blow up much if not all of the entire Gotham Police Department, which would kill Charlie as well; murdering countless people with Joker venom; attempting to drive 70 million people insane by having Ace Mind Rape them; attempting to nuke Gotham City; and going on a rampage with a Kill Sat. Perhaps his most infamous crime was when he brutally tortured Tim Drake into insanity and implanted a microchip in the child so that the Joker could take over Tim's body and perform a Post-Mortem Comeback.

Incapable of love or empathy, he abused his loyal son Kalibak, handed over his adopted son Scott Free to be tortured and brainwashed by Granny Goodness, and attempted to murder his other son, Orion, for opposing him. His servants are likewise subjected to torture or death should they fail or even question him. Setting his sights on conquering Earth, Darkseid launched a full-scale invasion, only relenting when the planet was declared off-limits by Apokolips's sister planet, New Genesis.

Even when beaten, the Anti-Monitor desperately tries to strike a deal with Aya to assist her in her plans to destroy reality itself to save his own hide. A megalomaniac who couldn't stand anything living except himself, the Anti-Monitor's narcissism was only matched by his petty sadism.
- Legion of Super-Heroes: Brainiac 1.0 was a menace from the past who quickly became one of the most dangerous foes the Legion has ever faced. Brainiac 1.0 was introduced in a flashback, where he shrinks and steals the city of Kandor from Krypton. Within Kandor was a power source that was stabilizing Krypton, but with this power source gone Krypton was soon destroyed. Brainiac 1.0 himself was destroyed long ago, but his programming resided within Brainiac 5, cut off from the other systems, waiting for a chance to be released. This chance came when Brainiac 5 accessed Brainiac 1.0's programming to gain knowledge to defeat Imperiex. Though Brainiac 1.0's knowledge was useful in defeating Imperiex, every time he used it Brainiac 1.0 was able to gain more control. Brainiac 1.0 slowly corrupted Brainiac 5, until eventually he took control of Brainiac 5's body. Then Brainiac quickly betrays Imperiex—who had helped Brainiac 1.0 take over Brainiac 5's body—killing him because he was no longer useful to him. Brainiac then proceeds with his plan to bring the entire universe under his control, by transforming all living beings in the universe into streams of data. After digitizing some planets, Brainiac returns to his home planet Colu and reprograms all the inhabitants there to serve as his army and aid in his quest to digitize the universe.

- Teen Titans: While Lighter and Softer than the comic, whenever these two show up, the tone darkens significantly.
- Slade—never called "Deathstroke" here—was a cold, manipulative criminal mastermind. Slade's main goal throughout the series was to find himself an apprentice whom he could mold into being just as cruel and ruthless as he was. First targeting Robin, Slade came up with various schemes to test the Boy Wonder's mettle before finally infecting Robin's friends with nanobots that would destroy them from the inside out should Robin not follow Slade's every command. When his plans for Robin were thwarted, Slade next turned his attention to Terra. Taking advantage of her status as an outsider who would never be accepted because of her destructive powers, Slade manipulated her into joining and befriending the Titans, betraying them and finally trying to kill them. After Terra finds herself in over her head while fighting the Titans and retreats, Slade physically abuses her for defying his orders. When Terra tries to quit her apprenticeship, Slade reveals that the suit he gave her to enhance her powers also gave him complete control over her body and vowed that he would never let her go. Though Slade dies when Terra rebels against him, he is eventually resurrected by the demonic Omnicidal Maniac, Trigon, to act as the demon's dragon. Slade took a vicious pleasure in his work towards ensuring the apocalypse, mind raping Raven with visions of her destiny as the Anti-Christ and selling out all of humanity to Trigon in exchange for Trigon giving him back his soul. Even when Slade rebels against Trigon, it isn't out of altruism, but because Trigon refused to honor their bargain.
- Trigon the Terrible himself, father of Raven, had conceived her solely to serve as a Human Sacrifice to become his portal into the realm of mortals so that he could destroy the Earth and all life on it, just as he did to Raven's homeworld of Azarath; Raven has been repressing her powers and emotions in order to avoid letting this come to pass. After Slade died in season 2, Trigon rescued him from Purgatory and offered him his life back were he to serve him in bringing Raven to her destiny. Trigon later comes to Raven in a vision, emotionally abusing her and cruelly attempts to break her will so that she submits to his demands of her. When Slade asks for his promised payment, Trigon calls the deal off because, thanks to Trigon's own manipulations, Raven had come to him willingly rather than Slade delivering her to him, and Trigon attempts to incinerate Slade on the spot. Trigon then destroys the world immediately as he arrives, turning all mortal life to stone and creating a Hell on Earth for him to reign over. He then plots to expand this destruction to all worlds in the dimension so that he could conquer the universe and all would worship him as a deity, and when the Titans fight back, he not only brings out their own dark sides to torment them for his amusement, but he tries to murder his daughter, whom he openly deems to be worthless.

In the present, Eshu arrives in Detroit under the guise of an ambassador and continues his quests to find the totems. To achieve his goals, Eshu bribes a thief into stealing the Fire Totem for him, then promptly kills the man once he's no longer of any use. With the Fire Totem in his possession, Eshu attempts to kill Mari to steal the Anansi Amulet. Failing in this, Eshu goes on a city-wide rampage in a fit of homicidal rage, burning down a massive portion of Detroit in an effort to draw Mari out. When Mari and her allies attempt to stop him, Eshu incinerates Mari's sister Kuasa right before her eyes before trying to kill Mari herself.

Bedlam masterminds the capture and trafficking of countless young metahuman children and teenagers, having them tortuously experimented on and drowning them in a thick tar of his own creation to awaken their metagene. Killing enough of them to warrant regular mass burials of failed experiments, those who do survive are mutated and auctioned off as living weapons to the highest bidder. In his own grab for power in Markovia, Bedlam has his own sister and the King assassinated before killing the Quraci assassin himself, throwing pressure onto the Quraci populace as a convenient excuse to screen for more metagenes. Bedlam even has his own niece and nephew, Tara and Brion Markov, subjected to the experiments, with no loyalty to his family, country, or anyone except himself and his own ruthless designs for power.
