The quintessentialCape andFlying Brick of the DC Animated Universe.
An alien orphan named 'Kal-El' who was sent into space as an infant to avoid suffering a cataclysmic death on his home planet of Krypton. His craft landed in a Kansas field and he was discovered by Jonathan and Martha Kent, who raise the boy as their son under the name 'Clark'. As he matures under the Earth's yellow sun, he gains superhuman powers such as nigh-unlimited physical strength and the power of flight. As an adult, he moves to Metropolis to work as a newspaper reporter. It is here he becomes aware of the corruption and evil in the world, decidinghe must use his gifts to right these wrongs, taking the moniker 'Superman' after a story of his deeds is published in the Daily Planet by Lois Lane, who uses the term.
After having worked long and hard since the end of "Legacy" (fromSuperman: The Animated Series) to regain the world's trust in him, it is he who first suggests that he and the other superheroes form theJustice League, in order to deal with future threats as great as the Imperium. According to the series' promotional information, he was shown to be the face of the League, as well as the peacemaker for the other members.
Adaptational Jerkass: A veryDownplayed Trope. Superman here is still a great guy and an example of heroism to all the other heroes, but he is not a nice as comic Superman who is a paragon of compassion and humility. This Superman is more prone to hold grudges (his first instinct upon seeing Darkseid after Darkseid briefly brainwashed Superman into serving him is that Superman wanted to destroy Darkseid), sees being Superman as setting an example to others(comic Superman never recognizes himself as an example and his motivation is just to help people because he loves the earth and cares about everyone), and is more prone to be dismissive or distrustful of others as while Luthor was, at one point, doing public works simply to get good PR, TAS Superman thought they were part of an evil plan and ignored Captain Marvel's opinion that Luthor was acting benevolent to the point of fighting Marvel (comic Superman, while knowing better than to trust Luthor outright, would never condemn someone without doing his own investigations first and would always take the opinions of his friends and teammates into account. He would also remain vigilant and prepare for the worst but never throw the first literal or figurative punch).
Adaptational Wimp: While Superman here is no slouch being able to land falling planes and send Darkseid across the city with one punch when he isn't holding back, he seems to strain and show effort when he pulls off the biggest of his feats which are impressive but never come close to his mainstream counterpart (comic Superman can hold a black-hole in his hand). He also can't travel interstellar distances under his own power and needs breathing apparatus when staying in space for extended periods of time. Comic book Superman, meanwhile, is so strong he can move mountains without much trouble and only ever shows effort when he's pulling off feats like moving weight equal to the mass of planets. Comic Superman can also travel interstellar distances, able to fly faster than light, and can hold his breath for a time equal to weeks allowing him to travel those distances.
Badass: Regularly goes up against enemies at least as powerful as him and far more ruthless, and has demonstrated that even without his powers, he's still not to be taken lightly.
Berserk Button: Harming his friends is never a wise thing to do since he's, well, Superman. Aptly demonstrated in the second part of "Hereafter," where he flew into enough of a rage toalmost smash Vandal Savage's head with a rock when the other man started describing in detailhow he slaughtered the other League members (but of course, theReset Button was very handy at the end of the episode), and in "For the Man Who Has Everything," where Mongul wasrunning Wonder Woman ragged.
Darkseid's mere presence also qualifies. He's the only character in the entire DCAU that Superman has NO reservations about killing.
Well there was also Mongul but that was more of passion. Darkseid is the only character that Superman can think about for more than five minutes and still want to kill.
Broken Pedestal:For Captain Marvel. Note that it was Lex Luthor's plot to make people distrust Superman and it worked well for Captain Marvel, that even Superman thought what he was doing was wrong, but the other founding members immediately showed that it was all a ploy.
At the start ofJustice League, many people on the whole world saw him as this, after theSTAS finale when Darkseid brainwashed him into leading the charge against his adopted homeworld. He only got proof that his efforts to fix his image paid off after Green Arrow stood up to him in "Divided We Fall".
Brought Down to Badass: Superman gets depowered and handles himselfon anAfter the End Earth pretty well,including forging a sword out of rebar and turning a pack of wolves that had been hunting him into sled dogs.
Luminus filters all sunlight except red to depower Supes, then baits him into aHard Light death trap. Supes manages to survive until he destroys the sun blocker.
The Other Darrin: Tim Daly was replaced with George Newbern inJustice League. The older Superman inBatman Beyond was voiced by Christopher McDonald, but this was due to the idea of Superman sounding more like his father Jor-El ashe got older; McDonald was the actor who voiced Jor-El inSuperman: The Animated Series.
Physical God: Becomes part of the conflict with Cadmus, post-Justice Lords.
Robot Me: It's emphasized in "A Better World" that Superman has robot duplicates of himself to keep things in check when he's not around. His Justice Lord counterpart useshis robot duplicates to maintain order at Arkham Asylum (and presumably elsewhere as well).
Shooting Superman: "Question Authority" provides one of the more blatant examples of this.
The Worf Effect: Got hit with this pretty bad when starting out inJustice League. The writers actually apologized for it and did their best to make up for it later on.
Thou Shalt Not Kill: Becomes a problem during the Cadmus arc due to the fact that his Justice Lord counterpart broke this code.
Darkseid, as stated above, is an exception. After their last encounter in his previous series, Superman has no problem killing him.
Played with actually, she starts out rather skeptical of Superman and while she constantly teases ClarkThe Late Mister Kent (and a few other episdoes) shows that this may be to cover up a crush on him.
A genius, multi-billionaire living in Metropolis who is the chief executive of his own company, LexCorp. In reality, he's a sociopath with a thirst for power and control, which he will gladly go to any length to have. He's an A-lister among Superman's rogues and constantly flexes hisVillain with Good Publicity as much as he possibly can. He later takes on various exploits to hamper theJustice League and out them as threats to global security so he may do as he pleases unopposed.
Badass Boast: "I'm already more powerful than all of you put together."
Badass Normal: Nowhere near Batman's level of training, but when you can forcibly assume leadership of a large group of superpowered beingsand keep them in line just through your intelligence and personal charisma, you qualify.
Crazy Prepared: Made damn sure he can turn the powers of any member of the Secret Society against them if they step out of line, as Doctor Polaris, Goldface, andGrodd found out to their sorrow. Also has an elaborate panic room hidden deep under a random Metropolis barber shop.
Diabolical Mastermind: After losing his company and resorting to more obvious villainy. Reaches its height in Season 2 JLU.
Dual-Wielding: Twin laser pistols in Season 2 of JLU.
A supercomputer AI from the planet Krypton who survived the planet's destruction. Now it seeks to gain as much knowledge from the galaxy as it can, by any means.
Fighting a Shadow/Actually a Doombot: The real Brainiac is an AI inhabiting a vessel in the depths of space; all those robot bodies that Superman destroys are just remote-controlled drones.
Kneel Before Zod: From "New Kids in Town," Brainiac makes a teenage Clark do this, even saying, "At last, the son of Jor-El kneels before me."Much like withSuperman II, Clark gave him a big surprise.
The absolute ruler of the wasteland planet Apokolips. Stuck in a truce with the neighboring planet New Genesis, Darkseid is always scheming about how to put the entire universe under his fist. Seeking the 'Anti-Life Equation', a powerful tool that could easily submit the entirety of existence under his thumb, he is a constant threat to planet Earth. He is Superman's most hated enemy for his many transgressions committed on Earth and Superman is willing to stop at nothing to see his end.
Badass: Possibly the most powerful villain in theDCAU and one of the few villains who regularly goes toe-to-toe with Superman on a physical basis, and comes out none the worse for the wear. He's an evil monster, but there's no denying that he'sBadass.
The Chessmaster: "I told you once Superman, if you would not be my knight, you would be my pawn."
Electric Torture: "It's called the Agony Matrix. Direct neuro-stimulation of pain receptors. All of them. Imagine the worst pain you have ever felt in your life times a thousand.Now imagine that pain continuing forever. Oh, that's right. You don't have to imagine."
Godzilla Threshold: He's the one villain that Superman does not hold back on. And, as has been noted, he's the one villain that Superman is perfectly willing to kill.
Playing Both Sides: Does this in the conflict between Superman and Brainiac inJustice League. Even though neither of them trust him, he puts them both in situations where they feel they need to work with him. He almost wins.
"I hope you appreciate, Kal-El, everything that happens from this point is on your head. The skies will rain fire, the oceans will boil, the streets run red with the blood of billions. Only then, when your last pitiful hope has been vanquished, will I end your life. Let's go."
The Other Darrin: When he turned up in "Hereafter" onJustice League, Corey Burton voiced. McDowell was back, though, in "Chaos at the Earth's Core" inJLU.
Sense Loss Sadness: The inability to taste, smell or feel anything drives him to the edge in less than a day.
Never My Fault: Her transformation was due to her stupidity of hosting a concertin the middle of a storm, Superman tried to get her to cancel it as she was both putting herself and the audience in danger. Typically she wouldn't listen and got hit by lighting. She blamed Superman for the mess, mostly from seeing on TV a reporter interviewing Superman accusing that he deliberately didn't push Leslie out of the way when the lightning struck.
Edward was an engineer at LexCorp who specialized in light and laser manipulation. He was a mole for Lois and was fired. So he decided to kill her in revenge.Then Superman got involved. Lytener took up the persona of Luminus and decided to get his revenge on Superman by bringing him down to normal. That failed too. Luminus is last seen fighting theJustice League after a jail break.
Stalker with a Crush: He becameThe Mole against LexCorp because he liked Lois, not because it was the right thing to do.
Villainous Breakdown: Is so calm and calculating when he has a powerless Superman on the ropes. When the satellites key to powering the big guy down get blown up, however, he (understandably) becomes quite panicky and desperate.
Rudy Jones was a janitor at STAR Labs and anExtreme Doormat, who was exposed to an experimental drug during a robbery attempt. He gained the ability to absorb the memories and abilities of anyone he touched, and he quickly put it to use by absorbing Superman's powers. Though his absorption wears off after a few days, Parasite made several more attempts to gain power and get revenge on everyone he feels wronged him.
Affably Evil: He’s amiable to everyone, even when absorbing their abilities. He can even be reasonable and easy to negotiate on a good day.
Evil Is Petty: Parasite would rather use his powers to get back at the world for pushing him around rather than use his power to it’s full potential. Of course, this makes him easy to negotiate with, and on a good day he can be satisfied with a plasma screen tv and a load of books.
