J'onn J'onnzz

Martian Manhunter (real name, J'onn J'onnzz) is the last son of mars, as well as a founding member of the Justice League.

Pre-Zero Hour
J'onn J'onnzz was a martian from the planet Mars, before it was destroyed by the White Martians.

Arrival on Earth
On February 1, 2002, J'onn made his way to Earth, where he attempted to blend in with humans.

Forming the Justice League
2 Days following, a fight broke out between Batman and Superman in Metropolis. After witnessing the arrivals of Wonder Woman, Flash, Green Lantern and Aquaman, J'onn joined the fight.

The fight was soon halted. Not long after, the dark lord Mordru attacked, but was defeated by the 7.

Following these events, the 7 formed the Justice League, creating a pact to protect Earth.

Death of the Justice League
On May 24, 2016, the founding members of the Justice League were killed tragically by Syphon, following a battle in Metropolis, joint by Green Arrow and Black Canary.

The only survivor of the founders was Martian Manhunter, who fled the scene.

Founding the New Justice League
On July 4, 2018, the Watchtower was re-launched into space, signifying the foundation of the second Justice League.

This League's founding members included Martian Manhunter, John Stewart, Hawkman, Hawkgirl, Zatanna, Incrediman, and Elastiwoman.

The second Leagues ranks expanded quickly by August 2019, nearly right before the Travelers were founded.

Post-Zero Hour
Following the temporal event known as Zero Hour, numerous changes occurred in the timeline.

One of the biggest changes being the fact that the original founding members never died, therefore the two leagues were always one in the new timeline.

The battle that killed the founding members in the original timeline did occur, however the battle resulted in Syphon being defeated by the founding members instead of them being killed.

Due to J'onn's telepathic abilities, he, over time, begins to remember the previous timeline and the events that erased it.
