My vision?
Justice League: Over the centuries the immortal Vandal Savage has tried to conquer the Amazon island of Themyscira as well as seize their gigantic doomsday weapon. He's failed countless of times under the guises of different personas over the years (like Ceasar, Alexander The Great, etc.). Present day, Lex Luthor has been elected President and his Secretary of Defense is none other than Vandal Savage (his past is unknown to everyone). Ambassador Princess Diane and Queen Hippolyta enter the U.S. to speak to the World Summit to join the UN, but are met with scorn for the other nations don't feel they can be trusted. Meanwhile, Clark Kent is meeting with friend Bruce Wayne (it's hinted that they know each others identities after having discovered this in a previous engagement). The meeting is interrupted when Superman's assistance is needed at a laboratory where a scientist (using unstable teleportation technology) transports a hostile alien lifeform onto Earth. The government arrive and take the alien after he is subdued.
Vandal Savage brings information to Lex about the Amazons concealing a WMD. While both secretly have their own intentions for the weapon, Lex moves forward with a plan to send troops over seas to Themyscira to confiscate the weapon, but knowing of the strength of the Amazons, he gets a reluctant Superman recruited into the "cause", as well as scientist Barry Allen, who has been working with the government to develop a super speed formula. After testing it on himself he's able to tap into the Speed Force. Military pilot Hal Jordan is recruited as well (unknown to the world, accept a good military friend, he has in his possession a power ring he aquired months ago from Abin Sur). Talk of war begins and Superman, Barry Allen (who takes the codename "The Flash" as well as a constume), Hal Jordan (still hiding his ring), and other American troops invade Themyscira and a fight ensues. Meanwhile Batman begins investigating Lex Luthor's true motives after growing suspicious (due to Superman, who is receiving mental thoughts from the martian previously, who has gain knowledge of Lex and Vandal's plans after reading their minds onc ehe was captured). Batman is eventually led to the Martian on a military base and busts him out.
Meanwhile on Themyscira, the Princess Diane, Artemis, and Hippolyta charge into the battle field. The fight rages, with Hal revealing his ring. In the end, Superman returns home with his men and meets with Batman and the Martian. The Martian explains the doomsday weapon and how his race years ago helped the Amazons create it. With the knowledge of what is going on, Batman, Superman, The Flash, and Hal Jordan confront the government and are then labeled communists. Meanwhile, the Amazons prepare to invade the U.S. As war is slowly looming on the horizon, Superman and the others (including the Martian) hide underground and prepare to fight, while Diane hears of this, now discovering that Vandal is behind this. Her people don't listen and they charge into battle with her refusing to fight, which leads to her to being banded a traitor to her homeland. Battle makes it to U.S. soil and the heroes fight both sides. Diane arrives and joins the ranks of the heroes (while saving a young child, she's dubbed "a Wonder Woman"). Hal uses his ring to design a costume to join the ranks, but is then captured by Vandal to use his ring to steal the weapon.
The fight in the U.S. ends, and Hal, Superman, and The Martian manage to defeat(?) Vandal and hurl the doomsday weapon off into space just as it's about to explode (thanks to a self-destruct procedure the Martian knew of). In the end, the heroes are given medals (sans Batman and the Martian) and seen as heroes to the World. Lex is impeached and his term is over.
For a sequel?
Justice League 2: The Justice League are handling a crisis at a harbor where a man who claims to be the king of Atlantis who is on a crusade is attacking a harbor for pollution. He is subdued by the Justice League and brought into custody where he is being interrogated. He reveals his name is Orin and he is left with the government. Meanwhile, Kator and Shayera Hol of Thanagar arrive to warn Earth of the impending doom of Darkseid of Apokolips and ask for help in searching for Orion, the only one who can defeat him. While Green Lantern, Superman, and The Martian Manhunter travel into space to help find Orion, Lex has secretly been recruiting himself a team of villains to form a sort of Anti-Justice League. Batman, The Flash, and Wonder Woman begin to search for them and do battle, when they discover Orion is on their roster. It's revealed that he's been on Earth for quite sometime and had arrived on a mission of peace, but had seen what the planet had to offer and determined that the violent savage humans didn't deserve to live, so he's accepting his father Darkseid's destruciton.
Meanwhile in space, Katar and Shayera betray the heroes, revealing that they were never searching for Orion and were working for Darkseid, who wanted any threats gone from the planet. After their planet had been ravaged, they had no cohice but to serve Darkseid. After failing to eliminate them (followed by an uneasy form of forgiveness) Superman orders them to take them to Apokolips to see Darkseid himself. Superman is the only one who can be brought to see the villains, and he finally meets him, learns of his objective and his quest for the Anti-Life equation and a small confrontation ensues, but Superman is rescued by the Thanagarians and they all return to Earth, where they meet the others doing battle with Lex and his Injustice Gang. After defeating them, Lex escapes with some of his recruits, but Orion is left behind. The heroes try to convince him that he needs to help, and he finally agrees and they prepare for Darkseid as he approaches Earth (Superman also decides to release Orin, who agrees to help after he's informed that his own kingdom will be destroyed along with the Earth).
Darkseid and his troops arrive on Earth and the battle begins. Lex makes his way to Darkseid's ranks and "sells his soul" to him, gaining a battle suit in the process and joins his side and is later defeated again. During the battle, Hal's hometown Coast City is destroyed. Eventually, Orion and Superman defeat Darkseid (with Katar being killed in battle). Though Apokolips' minions have been defeated, an enraged Green Lantern strikes the League for the casualties the fight cost. He then flies off into space on a self imposed exile.
Justice League 3: Nearly a year has past since Darkseid's attack, and Hal has yet to return. While the League is handling a situation with the terrorist organization Kobra at a nuclear plant, something goes wrong and the plant explodes while The Flash is inside trying to rescue more workers. A funeral is held to mourn the hero, and the League considers disbanding. A hurt Wally West, the nephew of Barry Allen, tries to unlock his equation into tapping into the speed force to pick up where he left off since he looked up to him. Meanwhile, artist Kyle Rayner is found by the last surviving member of the Guardians who presents him with the last power ring, giving birth to the Last Green Lantern. He warns Kyle of the coming of the villain Parallax, who in turn warns the Justice League (after getting used to the power ring). After struggling, Wally has cracked the code and presents himself as the new Flash to the League, who meet him with scoff as an amature and a child.
Soon, the League discover that Parallax is none other than Hal Jordan and that he must be stopped. But opinions are divided on how the problem should be handled, with Batman up for defeating Parallax and Superman up for saving him, which splits the team and causes confrontation. As the villains nears Earth and begins his rampage, new members are recruited and the heroes eventually are forced to work as a team again to stop their friend. In the end, it's revealed that Hal had become host to the spirit of Parallax, and after the spirit has been "exorcised" the now conscious Hal sacrifices himself to destroy Parallax once and for all.
In the end, the League continues to act as a team with new recruits all around the world.
