Justice League International

The Justice League International is a crime-fighting and peace-keeping organisation. Their satellite headquarters The Watchtower hovers above Earth's atmosphere. The Justice League International (JLI) fight large scale threats; as opposed to patrolling cities, the JLI sends their members when they are called upon by the Government, or when a cataclysmic, cosmic, or destructive force is detected.

Formation:
The JLI was originally the Justice League of America. During Starro's siege, the Guardians of the Universe dispatched Hal Jordan to avert the crisis. After Hal rid Coast City of all Starros, he went to Metropolis to do the same, but he was tremendously outnumbered. Luckily, Superman came to his aid.

Soon, Batman would alert the two of Starro Prime's whereabouts. They rendezvoused at the location, with Batman arriving alongside additional metahumans and superpowered beings: The Flash, Martian Manhunter, Wonder Woman and Aquaman. The 7 fought valiantly against Starro Prime, and ultimately won the battle; Starro Prime's drones retreated upon his defeat. They became the JLA, before constructing their Satellite and in addition to their Javelin: harnessing Zeta Beam technology, instantly making international travel much easier. A new Justice League of America would form, leaving the JLI to focus on deadlier Threats

Prelude
During the Flashpoint: Onset prelude, the Justice League International is seen spearheading the coordinated attack on Darkseid. the ensuing battle resulting in the deaths of Arsenal, John Constantine, Martian Manhunter, Shining Knight, Hawk and Dove, Cyborg, Hawkgirl, Hawkman and Kilowog.

In a fit of rage, regret and denial Wally West used his connection to the Speedforce to undo the attack, thus undoing the deaths of his friends. His alterations to the timeline were accompanied by some unforeseen changes.

Flashpoint Timeline
In the Flashpoint timeline, the Justice League hadn't formed. The final battle featured a pseudo Justice League; Batman (Thomas Wayne), Wonder Woman, Captain Marvel Jr fought alongside the Atlanteans, the Green Lantern Corps and the Titans against the forces of General Zod.

Aftermath:
After Wally West restored the timeline, the Justice League returned to their normal selves. Everything was almost exactly as the pre-flashpoint timeline was, with the exception of Barry Allen's presence.

Watchtower:
The Justice League's second base of operations, funded by Wayne Enterprises and Queen Industries. Their first base of operations being The Hall of Justice. The Watchtower contains living quarters, a cafeteria, meeting hall, observation deck, reactor core, hangars and Zeta Beam decks. The Watchtower is also equipped with a space laser, which acts as an extreme last resort, if the occasion ever arises. The laser is able to tear through titanium and even Nth Metal, and can possibly harm Kryptonians.
