135 Earth years ago, J'onn J'onzz was born on Mars and is a Green Martian. Many years later, J'onzz was accidentally teleported to Earth by a Zeta-Beam. There, he encountered Professor Erdel. With the power of shapeshifting, J'onzz blended in among the humans. J'onzz concluded that he wanted to be a force of good and took on the human identity of John Jones. He later became a superhero operating under the codename Martian Manhunter and co-founded the Justice League as the 7th member. He is also the oldest member at 135 Earth years old (biologically, a 45 year old male). Martian Manhunter is currently based in Chicago. As John Jones, he lives in room 307 of an apartment rented out by Mrs. Berkowitz.

According to Miss Martian, Martian Manhunter grew to become a true beacon of hope and stood for what Martian society could achieve. Eventually, Manhunter was known as the most famous Martian in history. Upon his return to Mars, it was declared a day of planetwide celebration. He had his own plans. Upon observing Batman, Aquaman, Green Arrow, and Flash take on partners, Manhunter decided it was time to introduce a younger Martian hero to Earth. He held a competition to find the next champion. M'gann M'orzz won and became Miss Martian. In reality, Manhunter first met M'orzz, his sister's daughter, when she stowed away on his ship.

On July 4th, Manhunter was present at the Hall of Justice to welcome Robin, Speedy, Aqualad, and Kid Flash. On August 3rd, he joined seven other League members to battle Amazo. He tagged along with Black Canary to the Cave afterwards to pay a visit to Miss Martian. On August 21st, he attended Kent Nelson's funeral. On September 7th, 06:41 Eastern Daylight Time (EDT), Manhunter made another appearance at the Cave. This time, he meant to wish both Miss Martian and Superboy well on their first day at Happy Harbor High School. When everyone present tried to help decide an alias for Superboy, Manhunter suggested a last name of "Kent." Superboy accepted under the belief it was to honor the late Kent Nelson, when Manhunter was actually borrowing from the last name of Superman's Earth name.

On September 14th, Manhunter joined Superman in a battle against the Terror Twins in New Orleans. This was part of a mission for the Team to sneak Superboy and Miss Martian into Belle Reve Penitentiary as the Twins. Soon after, the Martian Manhunter defeated Headmaster in Chicago. On September 22nd, Martian Manhunter and several other members of the Justice League arrived at the Cave to find it in ruins, the Team unconscious, and Red Tornado missing in action. Manhunter comforted his niece as she regained consciousness. He later helped synchronize key security protocols with the Watchtower mainframe. On October 2nd, 01:55 Central European Summer Time (CEST), Aquaman and Martian Manhunter fought Plant Creatures in Paris, France. They later arrived in Bayou Bartholomew with the rest of the Justice League.

On October 16th, Manhunter psychically linked the Team within an artificial reality for a training exercise. Miss Martian's subconscious took control of the simulation and members of the Team began to fall into a coma. Martian Manhunter discovered his niece possessed a telepathic mind far stronger than his, in terms of raw power. When he entered the reality, Manhunter was overcome by the Team's collective emotion and his thoughts were muddled. Once the other five members of the Team perished, Manhunter was able to remember his purpose and shocked Miss Martian out of the exercise. On November 11th, Martian Manhunter worked with Miss Martian, Artemis, Green Arrow, and Zatanna to destroy a Flying Ice Fortress. On November 22nd, Manhunter informed everyone that Miss Martian taking on Black Canary's form and kissing Superboy was based on a game on Mars. Black Canary was not pleased by the explanation.

On December 1st, Team Year Five, Martian Manhunter and Red Tornado were present on the Watchtower when Superboy, Superman, and Devastation were teleported away. Manhunter traced a powerful Zeta radiation signal to the Moon and concluded that's where they were beamed to. He then went to Metropolis. He was unable to density shift through the spherical field nor communicate with the alien ship above the city. Manhunter soon suggested it was time to confront the whoever was in the ship. As part of a ruse, he issued a telepathic and verbal messages to the ship while levitating the Flash. Martian Manhunter's telepathy and telekinesis failed against the ship's owner, Brainiac. Brainiac quickly detected his weakness and exposed him to heat. At 18:20 EST, Martian Manhunter regained consciousness and communicated with Nightwing.

In January the next year, Manhunter spent days trying to interrogate a Krolotean but achieving translation proved difficult. When it went suddenly catatonic, Mahunter turned towards the observation glass where Batman, Miss Martian, and Superboy stood. On January 26th, Manhunter left with several of the League to Rimbor where they would stand trial for the 16 hour rampage instigated by the Light. He asked Miss Martian to water the plants in his apartment. On June 20th, Manhunter and the rest were cleared of all charges. They returned to Earth at 23:16 EDT.
