Same as Q, I had an idea for an Ultimate League, so not necessarily an All-Star League. I'll probably write an accompanying fanfic to this outline one day.
Kal-El of Krypton
Ambassador
The Planet Krypton did not explode, and as such, its inhabitants would live, including Jor-El and his family. Years later, he and his brother Zor-El attempt a flight to the planet Earth with an expiremental space-craft. Returning to Krypton a year later, they decide to take their families along (as well as some others) to the planet Earth and move in, to share their Kryptonian knowledge with the world.
Kal-El grows up in the city of New Kandor, a hidden city on Earth, fully aware of his Kryptonian heritage. Under the effects of the yellow sun he gains superpowers, and for a long time uses them to protect the city. Now, with the excistence of New Kandor revealed to the public at large, and an influx of Kryptonians who are re-locating, Kal-El has moved to a global perspective where he serves as the Ambassador of Krypton and New Kandor, and agreed to become the chairman of a UN-sanctioned Justice League.
Bruce Wayne of Earth
Surgeon
Bruce Wayne's parents did not die, but instead were saved by the then-newly relocated Jor-El who, with the use of the powers he gained under the Earth's yellow sun, took a trip on the world, only to save the lives of the Waynes in Gotham City's Crime Alley.
Young Bruce Wayne would grow up to go to med-school, and studying under Dr. Charles McNider (former war-time superhero Doctor Mid-Nite) would become one of the best surgeons in the world. Once approached by CIA to perform surgery on some of its most secret operatives, Bruce Wayne became the target of a conspiracy to overthrow the government. Resorting to martial arts skills that he had picked up as a kid, Bruce Wayne also used his keen intellect and uncovered the entire scheme. Inspired by this deed and his mentor, Bruce Wayne created the identity of the Batman.
With the formation of the Justice League, Batman has unofficially become one of its members, the UN keeping his involvement a secret. Officially the Batman does not exist.
Diana of Themyscira
Ambassador
Diana of Themyscira is an Amazon, and serves as the female race's greatest warrior. After a short conflict between Themyscira and the UN, Wonder Woman agreed to join the Justice League and become the Amazon Ambassador.
She is a warrior at heart, and has found herself to feel strangely comfortable around men with a similar warrior spirit.
Orin of Atlantis
Ambassador
Although bearing the curse of Kordax, the one known as Aquaman would return to his native Atlantis to rise as its rightful ruler. Seeing the decay and pollution of the waters, Aquaman has sometimes led missions of warfare to the surface land, but has mellowed after Atlantis joining the UN.
Orin serves to be the UN ambassador of Atlantis, and also keeps his part-time job as King of the waters, leaving most duties to his advisor Vulko. Of all the Justice Leaguers, he is the most absent, dividing his time between his kingship and his role as superhero.
Guy Gardner of Earth
Green Lantern of Space Sector 2814
When Abin Sur crashlanded to Earth, he sent his ring out to choose a worthy succesor. Social worker Guy Gardner was closest, and was picked to become the new Green Lantern. After training on Oa, Guy returned to Earth, and has since acted as the only 'legitimate' superhero on the planet, serving not only the UN but also the Guardians of Oa.
Forsaking his secret identity, Guy has become one of the most promising Green Lanterns, dividing his time between the Justice League and his Green Lantern duties, spending a lot of time off-world for both groups, either protecting other planets or doing monitor-duty.
Barry Allen of Earth
Police scientist
It was inevitable. One of Krypton's scientists found a human/kryptonian hybrid to be possible, and as an experiment injected various pregnant mothers with a strange mix of Kryptonian genes. Of all infected, it would be only Barry Allen's mother that would survive and produce offspring.
Inheriting the superspeed that came natural to Kryptonians under a yellow sun, Barry Allen broke all speed records but sought his refuge in police work, becoming a scientist. Eventually his powers matured, to even surpass those Kryptonians that had been around longer than him. He truly became the fastest man alive.
Seeing a potential to do good, and inspired by the war-time hero Jay Garrick (the first Flash), Barry Allen followed in those footsteps and became the second Flash.
J'onn J'onzz of Mars
If the existence of the Batman is classified, the Martian Manhunter's even moreso. Arriving on Earth after his planet's destruction, J'onn assimilated himself into Earth Culture, adopting the identity of John Jones. Ultimately, he would be captured by the government, and was used as a mass-telepathic tool, serving as a large information-broker.
With the formation of the Justice League, J'onn has served as the team's co-ordinator, and has helped them out on some adventures, unbeknownst to them. Even to the Justice League, the full extent of his existence remains a secret.
Volume 1 outline
New Kandor is growing and growing. More and more Kryptonians are travelling to Earth, and the population keeps increasing by the day. While Jor-El, acting as the ruler of New Kandor, must contemplate what to do with this influx, his son, is fighting alongside the League against the Appellaxan invasion.
Seven aliens have come from the heavens in order to use the Earth as battleground for their power struggle. With the Justice League already formed, the Appellaxans are quickly taken care of and an alien invasion is averted. The League is heralded all over the world, except in the Metropolis offices of Lex Luthor.
Seeing that, although an Appelaxan crisis has been averted, the steadying influx of Kryptonians can not be a good sign, Lex Luthor starts to openly discredit the League, and creates his own counter-organisation. K.R.Y.P.T.O.N.I.T.E. is formed, as a public group that oppose the coming of the Kryptonians. The group is funded mostly by the elite of society, amongst them Lex Luthor, Oliver Queen and Bruce Wayne, who all openly wear a black bandana with a red K on it.
After another succesful mission with the League, Superman is bombarded with questions by the press, as well as a group of protestors who do not stick to only throwing questions at him. Although he is openly defended by the other public members of the League, it is to no avail, as the anti-Krypton movements gain in members by the day, as fear for other superpowered Kryptonians grows.
Meanwhile, Bruce Wayne struggles with his place amongst the League. Openly funding K.R.Y.P.T.O.N.I.T.E. while working alongside Superman is leaving him in unrest, and he eventually decides to travel to New Kandor. There, he stumbles upon three Kryptonians, obvious criminals, who have figured out means of getting powers on the planet, and are using solar technology to do so.
Returning to the League, Batman rallies them to prepare for the three Kryptonians, and his already fragile alliance with Superman has crumbled. Eventually, after a League meeting, Superman stays behind, using his X-Ray vision, finding out Bruce's true identity.
"Bruce, how can you support that group?"
"Considering you just proved my point, how can I not?"
Finally, sufficiently powered, the three Kryptonians start to wreak havoc on the planet, and the League is called in to take care of them. Meanwhile, Jor-El has decided that his actions have brought this upon Earth, and that ultimately, it's his responsibility. He starts to prepare for the evacuation of New Kandor, and for its citizens to return to Krypton.
The battle with the three Kryptonians is fought across the world, as Superman, Wonder Woman, Aquaman, Flash and Green Lantern are narrowly able to defend themselves against their combined powers. The recent tensions with the Anti-Kryptonian movement has had its effect on the group, and they work less as a team.
While the League fights the Kryptonians, Bruce has once more travelled to New Kandor, in search of a way to take out the criminals. There, he finds Jor-El's own diary, and in it, it is revealed how Jor-El saved the lives of Martha and Thomas Wayne, and his sadness at seeing Bruce funding K.R.Y.P.T.O.N.I.T.E.
Seeing the error of his ways, the Batman arrives on the battle, and is able to use a drainer of solar energy to sap the powers of the Kryptonians. In the moment however, a young reporter called Jimmy Olsen is able to photograph the Batman. While the battle was fought however, New Kandor has been evacuated. Waiting for his son on a hill top nearby New Kandor, is Jor-El.
The departure of the Kryptonians has gone past Kal-El, who has been in continious hiding from the public, and later, fighting the criminals. Batman points him to where Jor-El is. Kal-El intends to travel back with his family too Krypton, but Jor-El urges him to stay, and prove that not all Kryptonians are criminals.
One month later, the League has all but been disbanded:
- Superman remains sitting on that hill-top, looking at the stars.
- The existence of the Batman is now public, but has been declared dead by the government. Bruce Wayne has been spending a lot of time with his parents.
- Guy Gardner has decided to leave Earth and patrol his sector.
- Aquaman returns to Atlantis, seeing how the surface people can quickly turn against its heroes, and outsiders.
- Wonder Woman and Flash (as well as the Martian Manhunter) remain in the service of the UN.
