In addition to portraying comics-accurate and fan-favorite takes on beloved DC heroes, the DCAU also featured a story that was equal parts familiar and fresh. This was partially because the DCAU created new characters and teams, like a future version of the Justice League known as the Justice League Beyond.
First appearing in Batman Beyond Season 3, Episode 8, "The Call," Justice League Beyond is led by an older Superman, who invites Terry McGinnis' Batman to join the team. Later, the Justice League Beyond appears in Justice League Unlimited and then the comics DC Universe.
Here's a breakdown of the team roster.
Superman
This elder Kal-El from the DCAU appeared in his own show, as well as Justice League and Justice League Unlimited. Though he has not aged at the rate of his fellow heroes thanks to his Kryptonian physiology, he does appear to be in his 40s or 50s.
In the future, he invites Batman Beyond to join the team. This Superman is as powerful as -- if not more than -- his younger counterpart. He later receives a solo comic.
Big Barda
In the New God joined the Justice League Beyond and became a fierce and loyal member along with her husband Mister Miracle. When Terry joins the league she is initially skeptical of his admittance and very hard on him before loosening up once she realizes he can be trusted after helping save Superman and the rest of the team from Starro's control.
Along with Superman and Batman, she essentially forms the futuristic version of the Justice League's big three. Being a New God Barda is incredibly strong and ages at a slower rate than humans. She also uses a variety of New God and Apokoliptan technology.
Batman Beyond
Terry McGinnis, star of Batman Beyond, is the successor to Bruce Wayne as the holder of the Batman Mantle. He is essentially a genetic son to Bruce Wayne, bred by Amanda Waller in secret to eventually take over the mantle of Batman. While initially refusing full-time membership to the League after helping them with their Starro problem, he eventually assumes a leading role.
While not as physically strong or combat-savvy as the initial Batman, Terry is athletic and sees his abilities enhanced by his Batsuit. The final Batsuit, initially built to support an aging Bruce Wayne, offers boosts in strength, agility and durability. Terry also uses a variety of Batman technology, such as Batarangs and various devices in his utility belt.
Aquagirl
Mareena, daughter of Aquaman, is the Justice League Beyond's resident Atlantean. While she's not very receptive to Batman's addition to the league, she is more friendly than the rest of the team.
Being an Atlantean, she has the power to breathe underwater and she is an adept and speedy swimmer. Like her father, she also can communicate with aquatic life while also maintaining is the power of Hydrokinesis.
Static
Virgil Ovid Hawkins, also known as Static, is a metahuman who made his debut in the DCAU series Static Shock. Presumably the future version of Virgil from the show, Static has electricity-based powers of electromagnetism, electrokinesis and magnetokinesis.
Static was not an original member of Justice League Beyond, but he eventually joins on a more consistent basis. He even helps the League team-up with a previous iteration to change the future in Justice League Unlimited.
Micron
A future counterpart to the Atom, Micron has the power to shrink and grow at will, as well as fly, with the help of his suit. Micron is the victim of Superman's initial attack while under the control of Starro, leaving him incapacitated and in stasis until he can gather strength to assist the League in its efforts to defeat a controlled Superman.
Micron also plays a large role in the Justice League Beyond comic series, acting as a spy in the beginning and continuing to use his size-changing powers to aid the League in various ways.
Warhawk
Rex Stewart, aka Warhawk, is the son of Green Lantern John Stewart and Hawkgirl Shayera Hol. His fierce demeanor and impulsive temperament initially lead him to but heads with Batman upon inclusion. However, after he's initially thought to have been killed, he returns and backs up Batman, eventually leading to mutual respect between the two heroes.
Being that he is half-human, Warhawk lacks the organic wings of a Thanagarian, but dons a pair of artificial wings with full-body armor. He also possesses his mother's super strength.
Green Lantern
Kai-Ro, a Tibetan Buddhist monk, is the Justice League Beyond's current Green Lantern. It is unknown how he received his ring or what happened to the Lanterns before him, but he is known to wield the ring very well despite his relatively young age.
He is much calmer than his co-members of the Justice League and often advocates for peaceful solutions to conflicts. He maintains his membership with the League into adulthood.
The Flash
Danica Williams is Wally West's predecessor as the Flash. While she does not appear in the animated series, she makes her debut in Adam Beechen and Dustin Nguyen's Batman Beyond Unlimited #13 and joins the team in Derek Fridolfs and Jorge Corona's Justice League Beyond #19.
She is a speed force conduit like other Flashes, granting her the ability of enhanced healing, enhanced senses, phasing, superhuman stamina and superhuman speed. She uses her connection to the speed force to communicate with previous Flashes, who aid her in journeys.
Mister Miracle
Scott Free, the adopted son of Darkseid, is the world's greatest escape artist known as Mister Miracle. Along with his wife Big Barda, he joins the team sometime in the future. He is not shown as a member of the League in the show but appears occasionally in the digital comic series Justice League Beyond.
He is a superb athlete with enhanced strength, agility, endurance, coordination and reflex. In addition to his athleticism, he was trained by Granny Goodness in the pits of Apokolips, thus making him an elite warrior and escape artist.
Captain Marvel
Billy Batson eventually joins Justice League Beyond in Derek Fridolfs and Ben Caldwell's Justice League Beyond #24, as he swoops in to save the day.
He still maintains his powers from the wizard Shazam and he still has not aged. He eventually goes on the begin a relationship with Aquagirl.
Ur-Zod
A result of cloning by Wonder Woman and Lord Superman in an attempt to initiate peace on Earth-50, Ur-Zod is a Kryptonian-God hybrid. His unique DNA grants him a cross between the abilities of a Kryptonian and Amazonian, along with his Mechanokinesis giving him the ability to manipulate technology.
He first appears in Christos N.Gage and Iban Coello's Justice League Beyond 2.0 #4, eventually joining the team as a junior member of the Justice League Beyond.
