- Voiced by: Sumalee Montano
The personal guard of Queen Atlanna.
- Adapted Out: Her backstory of being from the kingdom of Xebel is absent for this version.
- Adaptational Modesty: Her cleavage is covered in this version, as opposed to her comic version who sports Absolute Cleavage and Cleavage Window.
- Amazonian Beauty: This version of Mera has a distinctly feminine-yet-muscular build, likely owing from her role as royal bodyguard in this continuity.
- Boobs of Steel: Like Wonder Woman, this applies to her.
- Composite Character: This version of Mera takes more visual cues from Artemis than comics Mera, with her long red ponytail, band across her forehead and more Amazonian traits.
- Does Not Like Shoes: Like most of the Atlanteans. Her heels and toes are exposed.
- Fiery Redhead: We see how fiery she can get.
- Kung-Fu Wizard: Be it spells or Melee she will mow down enemies by the dozen.
- Making a Splash: She can freely summon a vortex of water when it suits her.
- Ice Magic Is Water: In battle, she kills several soldiers using weapons made of ice, such as blades, whips, and arrows.

- Official Couple: Begins a relationship with Arthur/Aquaman.
- Appearances: Batman: Bad BloodVoiced by: Geoff Pierson
Kate Kane's father.
- Action Dad: He was still in the Army when he had children.
- Alcoholic Parent: Implied. He was seen with a flask when he and Kate were having dinner and apparently his doctor informed to give it up.
- Bald of Awesome: He's bald, a former colonel, and a pretty Cool Old Guy.
- Dark and Troubled Past: His family was captured and ended with his wife and one of his daughters being murdered by them.
- Good Parents: He always supports and encourages Kate in either her choice to be "Batwoman" or finding a nice girl.
- Nice Guy: He's a very sweet man.
- Open-Minded Parent: He thinks nothing of Kate being a lesbian, even encouraging her to find a girlfriend.
- Outliving One's Offspring: While Kate is still alive, his other daughter was murdered as a child.
- Papa Wolf: Colonel Kane shot the men who were about to kill Kate.
- So Proud of You: Constantly states how proud he is of his daughter and that her mother and sister would feel the same way.
A detective from Gotham.
- Appearances: Teen Titans: The Judas Contract
A young man who was the trial candidate for Brother Blood's power transfer machine.
A male stripper being tracked by Task Force X on Waller's orders to retrieve a card he possess.
- Canon Foreigner: There never was anyone named Steel Maxum in the comics. Especially anyone that used to be Dr. Fate.
- Chippendales Dancers: His main profession, though he uses an Egyptian motif in his performance.
- Dating Catwoman: He seem to have a thing for Silver Banshee while he was Dr. Fate, and she seemingly returned the sentiment.
- Legacy Character: He once served as Dr. Fate, being chosen by Nabu himself. He lost the position after Scandal and Knockout stole the Card from him.
- Mr. Fanservice: Due to being a male stripper, most of his scenes have him shirtless all the time.
- Naked People Are Funny: Task Force X kicks him out of their bus after they have no use for him, leaving him naked on the road. He is later stopped and arrested by cops who poke fun at his nudity.
- Uncertain Doom: He is last seen being approached by Professor Zoom and his minions. Though its unknown what ultimately happened to Steel, its unlikely he came out of it alive knowing Zoom.
- Small Role, Big Impact: Why does a character like him who didn't even originate from the comics have a folder all for himself? Besides the fact he was a former Dr. Fate before, he used to keep the MacGuffin in Hell to Pay which every bad guy was after.
- Walking Spoiler: He was Dr. Fate once.
- Appearances: Justice League: Throne of Atlantis, The Death of Superman, Reign of the Supermen, Batman: Hush
Clark Kent's co-worker at the Daily Planet.
- Action Survivor: In the climax of Reign of the Supermen, she manages to come out of Superman and Hank Henshaw's fight in the Watchtower with just a few minor heat vision wounds. Furthermore, she turns off the Watchtower's solar shield, allowing Superman to regain his full power and defeat Henshaw.
- The Missus and the Ex: Becomes good friends with Diana by the time of Reign of the Supermen.
- Promoted to Love Interest: When the universe started, it followed the New 52's example of Superman and Wonder Woman being a thing. However, with The Death of Superman, the universe established that Clark and Diana had an Offscreen Break Up and it switched to the more traditional pairing of Clark and Lois.
- Official Couple: With Clark as of The Death of Superman.
An inventor who comes up with a special suit of armor to keep up Superman's legacy following his death.
- Drop the Hammer: Steel's main weapon is a massive steel sledgehammer. It can be thrown and return to Steel's hand and has a thruster built inside to increase the power of his blows.
- Early-Bird Cameo: He appears in Throne of Atlantis, aiding a fellow construction worker from Atlantian robots. Similarly to his comic counterpart, Superman saves him from death and he becomes inspired.
- Legacy Character: One of four people to take up the S-Shield following Superman's death.
- Powered Armor: Wears a solid gray armor sporting the S-Shield in the same color and a red cape. It's also much sturdier than the original featured in the comic story.
- Voiced By: Cameron Monaghan
A clone of Superman and Lex Luthor created by the latter after Superman's death to be a LexCorp-brand hero.
- Casting Gag: His voice actor Cameron Monaghan is best known for portraying the incredibly villainous Jerome Valeska, a predecessor to The Joker of all people, while Superboy, while a little rough, is firmly a hero.
- Cloning Blues: Doesn't take learning the truth too keenly, but recovers after some kind words from Lois.
- Composite Character: While his design is very similar to Superboy's original appearance, he has a few mannerisms and appearance cues from Jonathan Samuel Kent, Superman and Lois' son in the main comics. He also briefly works for Luthor, similarly to the Matrix Supergirl.
- Conditioned to Accept Horror: He has next to no reaction beyond sarcasm to Lex's anger, even when it toes violence. He also has a rather muted response to hearing a scientist who helped create and raise him die horribly.
- Corporate-Sponsored Superhero: Superboy was created to be what Luthor always wanted: A Superman on a leash. There are even LexCorp logo patches on his jacket, rather than the S-shields from the comics. Superboy tears these off in the last third of Reign, to show Lex he's washed his hands of him.
- Do Not Call Me "Paul": He temporarily has his comic counterpart's attitude of not wanting to be called "Superboy".
- Family Eye Resemblance: The only physical trait Superboy inherited from Luthor is his grey eyes. Everything else is Superman.
- Jerk with a Heart of Gold: He's got an ego and, like a typical teen, rebels for the sake of it, but Superboy understands what makes a hero and genuinely wants to be one.
- Kidanova: Though he's biologically a teenager, he's very popular among girls and very aware of it. He's not even above trying to hit on older women like Lois.
- Half-Human Hybrid: His genetic makeup is half Kryptonian and half human because Lex Luthor, in his egotism, sought to "improve" Superman's DNA by mixing in his own. It seems to be what made him more stable than the other Superman clones.
- Happily Adopted: At the end of Reign, Superboy is living in Smallville with the Kents under the name "Conner."
- Like Parent, Like Child: He has Superman's strong moral compass and lighthearted sense of humour, but also Lex's love of the limelight and knack for one-liners that get under people's skin.
- Muscles Are Meaningless: Endowed with super strength, but built like a stick.
- Really Was Born Yesterday: He was "born" a teenager, and is a few months old at the time of Reign.
- Socially Awkward Hero: Most of Superboy's showboating is compensation for his limited knowledge of how to interact with real people, besides what he's learned from 90's sitcoms.
