I am Mars' sole survivor. There is a reason for that.
~ Martin Manhunter

The Martian Manhunter (real name: J'onn J'onzz) is a superhero from DC Comics and a regular member of the Justice League - he is one of the last surviving Martians and has taken on the role as a hero on Earth due to his affinity for the planet, disguising himself as a human due to knowing that humans will fear his alien appearance. He is one of the most powerful heroes in the Justice League and has displayed a vast array of powers such as shapeshifting, superhuman strength, telepathy, and flight.

In the Justice League of America TV movie, he was played by the late David Ogden Stiers.

In Justice League: The New Frontier, he was voiced by the late Miguel Ferrer.

Silver Age Origin

Martian J'onn J'onzz was pulled from his homeworld, and time, to Earth in an experiment with alien technology. Scientist, Saul Erdel, had been experimenting with alien technology, possibly Martian, to try to perfect teleportation. His experiments eventually paid-off, though not in the way he intended and his first successful teleportation had randomly locked onto J'onn J'onzz and transported him from Mars to Earth.

Witnessing the sudden appearance of the large green humanoid caused Erdel to have a heart attack and stranded J'onn on the planet. J'onn, confused as to what had just occurred, decided to assume the form of the strange alien species native to the planet that he had been transported to.

After going undercover as a human, reading minds and finding out all he could about Dr. Erdel's research, J'onn eventually put together what had happened and realized he was on a different planet, Earth, one he had thought to be devoid of life. J'onn began working on a way to communicate and return to his home planet but also plied himself to helping the humans as dangers arose for them, as they were severely limited with an inability to do basic things like fly, read minds or alter their shape.

J'onn would eventually find that he was not just pulled through space but time and his people had died off years ago. With no other planet to call his home J'onn decided to dedicate himself full time to protect his new home and use his powers to help ensure the safety of the Earthlings. In his pursuits he would come to join the Justice League of America as one of their core members.

It's beautiful isn't it? Almost reminds me of home. I don't think the human race understands just precious this planet is. That's why I wanted you in the Justice League, Animal Man.
