Last Son of Mars, Defender of Earth, and member of the Justice League.


The Martian Manhunter is simultaneously a global champion for moral justice and an alien invader whose deeds have little regard for tyrannical law. He is best known in third world regions who typically see little heroism applied to their plight giving him an almost 'Superman' level of notoriety. Most importantly, he works with the members of the Justice League to bring Peace, Harmony, and Prosperity to this World so it doesn't suffer the same fate as his own.


Tens of Thousands of years in the past an extremely dangerous race of beings called "the Burning" caused large fires to help themselves reproduce asexually. In order to prevent the Burning from destroying much of the universe, the Guardians of the Universe split the species into the Green Martians and the White Martians, changed their reproductive behavior, and instilled in them a fear of fire.

Roughly ten thousand years ago, Mars (called Ma'aleca'andra by the inhabitants) was a living world, populated by a race of humanoids divided by skin color. The Green Martians known as M'yrnn and Sha'sheen gave birth to twin sons. The bearing of twins was uncommon among the Martian culture, and as such, the first of the twins was named J'onn J'onzz, whose name means "Light to the Light." J'onn's brother, however, was born a mutant, bereft of a Martian's innate ability to communicate telepathically. He was named Ma'alefa'ak, whose name means "Darkness in the Heart.

Years passed, and J'onn's brother Ma'alefa'ak grew to despise everything about Martian culture. In an ambitious endeavor to commit full-scale genocide against his own people, as well as make it look like his brother caused it, he engineered a contagious virus known as H'ronmeer's Curse. The virus would react to telepathic energy and carried from one Martian to the next whenever they elected to use their psionic powers. However, before he could implement his plan, the populace received a psychic warning, which the government perceived as a threat and recruited several of its people, including a young newly trained Manhunter J'onn J'onzz to investigate.

While on their mission, his Ma'alefa'ak unveiled a double-cross, killing all of the Manhunters except J'onzz and then used their blood for a magic ritual that empowered J'onn - permanently, against his will. Ma'alefa'ak disappeared after the ceremony, disappointed that his ritual did not cause the havoc he had hoped for, but ultimately would lead to his own demise. J'onn would continue hunting for his brother Ma'alefa'ak, and discovered a monster - the cause of the psychic warning that had sent him on the mission in the first place. Taking the shape of J'onn J'onzz's, the monster explained that it was the embodiment of the dying Martian biosphere, trying to warn the populace to help it. However, the embodiment decreed that what he had seen of the populace, specifically his brother, showed they were unworthy, and Mars and the Martians were sentenced to death.

A plague responded to the Martian's innate fear of fire, causing them psychosomatic stress so intense, that their bodies and minds would literally burst into flame. J'onn was anguished as he watched his family burning to death before his very eyes. The trauma of the event shattered his psyche, and nearly drove him mad. The entity ended up throwing J'onn to Earth, where he lost himself in an infinity of identities before finally, almost nine thousand years later, he attempted to rebuild his shattered psyche to become a hero once again.

The last several decades on Earth J'onn has spent familiarizing himself with the new planet he was on. He had vague memories of his past, but given the psychic shock he experienced there were vast gaps in what he remembered. He learned about these people, watching them change, and watching them adjust to the changes through time. Roughly ten years ago, he met another alien on Earth known as Superman. He had watches from the sidelines as Kal El, and other heroes formed an organization to protect the planet Earth. As he watched, and learned more he decided that he would do what he could to protect this planet with them. He reached out to Superman, Wonder Woman, and Batman to offer his abilities and knowledge to their cause. He has since brought not only his powers, but his personal beliefs on the quest for the Life Equation from his Martian Culture to make Earth the planet it has the potential to become.

After his near-death and the loss of his heart helping the Justice League take down the Red Lanterns, J'onn has changed. He spent months away from the Justice League, despite his quick physical recovery. There are signs… suggestions… he no longer has all his memories, though his every-stoic expression serves to hide it as well as he can manage.

Character Details

J'onn appears to have a cold and alien personality on first interacting with most humans. It is a demeanor borne out of both his native ability to communicate his emotions telepathically rather than through body language, as well as an inherent wariness of the human species, which doesn't always react favorably to alien beings.

In truth, he is given to thoughtful reasoning and careful — some would say at times cold — statement of logic, and is typically not driven by emotions. He is mentally far more expressive, however — his emotions shine through with a lot more clarity and nuance in any telepathic conversation, though given humans typically are wary of such interactions, he tends to avoid unwanted mental communication.


Image Name Relation Information
Wonder Woman Confidant and Ally Diana has always been a dear friend and ally like the other Founders of the Justice League. She has been a source of consistent friendship, and someone that looks past his Alien Exterior. if Diana needed him, he'd be there without a second thought
Superman #AlienBros Kal and J'onn have always got along splendidly. Their similar story of loss and finding a new Home on Earth is something very few will truly appreciate, J’onn has been able to talk to Kal not only about his own concerns, but has been a sounding board for Kal when he most needs it. J’onn considers Kal as close to a brother as he has ever had.
Green Lantern #TeamGreen Since their first meeting, the Green Martian and the Green Lantern have been able to instinctively cover each others weaknesses. Hal’s ‘Charge In First’ mentality blends well with J’onn’s measured tactical methodology. As with many of the Justice League, J’onn offers Hal the wisdom of his years and the non-judgmental opinion of a true friend.
Batman Fellow Detective and Inventor Despite some of the other Leaguers view of Batman, J’onn has always understood the reason behind Bruce’s methodology. J’onn has always been there to help Bruce without any preconceived notions, and working together to protect the Leagues best interests. Sometimes you need to be able to make Hard Decisions, but never will you compromise Who You Are. For that, Bruce will always have J’onns respect and friendship.
Black Canary Big Sis Dinah has always looked out for J’onn, and in a way has brought him into her family. There are few Humans who are capable of seeing past the stoic demeanor, but Dinah saw it on Day One. Both have had a rough life, both will be there for one another, and may the gods help anyone that messes with his Big Sis.
Starfire Shared Tragic Soul Just recently met and battled together, J’onn has heard a frightening story that is too similar to his own. Her perseverance in the face of her own tragic tale is something that J’onn respects greatly. It reminds J’onn that his story is not the only dark tale, and that friendship can carry you through the roughest parts of your life.

New player as of May 2018. Happy to honor past relationships and RP as is, although J'onn's memories of recent years as a result of his recent trauma is spotty at best, allowing for changes where needed (and to help the new player in stepping in without messing things up!)
