Martian Manhunter#0(1998)

J'onn is at the JLA Watchtower and speaks with Superman concerning his ever-growing feelings of alienation. He decides to embark upon a pilgrimage to visit the ruins of his home world, Mars. Before piloting a Jump Shuttle and arriving on Mars, J'onn recalls the last days of his people and explains how he and Superman are similar as the last survivors of their alien peoples but they will always be different as Superman was raised by humans and identifies with them. The telepathic plague of fire known as H'ronmeer's Curse, raged throughout the Martian civilization. The only way to live through the mental virus was to stop using the native Martian telepathy that connects all Martians in the "Great Voice". J'onn held out in spite of the overwhelming feelings of isolation but his wife and daughter were unable to keep from using their telepathy and thus became victims of the plague as well. Grief-stricken, J'onn attacks the architect of the plague: his brother Ma'alefa'ak, who was incited by jealousy at being the only Martian without telepathy. The two briefly fight in a temple at Olympus Mons before it explodes and J'onn wanders his home planet as the last of his race. For an indefinite time, he tries to recreate his family and loved ones—shape-shifting into versions of them to provide himself some company and ease his conscience at being unable to stop the spread of the Plague. Suddenly, a transmitter beam from Earth whisked J'onn away, transporting him across space and time where he met the scientist Dr. Saul Erdel (who introduces himself as James Erdel). Erdel has previously discovered a teleporter buried in the ground and his first time using it causes it to violently explode, destroying his home laboratory. J'onn is horrified and confused by fireball but comes to his senses to save Erdel from the wreckage. Erdel dies on his lawn explaining what has happened and J'onn turns invisible as the Denver Police Department show up on the scene, lead by Lieutenant John Jones. J'onn becomes curious about humanity and its diversity and so follows Jones in his personal and professional life. He is present when to of Jones' fellow officers arrive at the lieutenant's apartment ostensibly to accompany him as he gives his testimony in a trial against a major mob boss. In reality, the officers are there to kill him for the mob and J'onn intervenes too late to stop them. He knocks out Officer Kawicki but Officer Morgan and Lieutenant Jones kill one another in a shoot-out. J'onn decides to morph into Jones' place and to testify in the dead man's stead as he has previously read Jones' mind and knows all of the facts of the case. This tragedy convinces him to commit his life to bringing the guilty to justice and he continues to serve as Jones and later join the Justice League of America. In the present, J'onn ends his storytelling and convinces Superman that he doesn't need to be accompanied on his first trip back to his home planet. When he arrives, he forgives Mars for the death of his family and forgives himself as well. Unbeknownst to him, Ma'alefa'ak, sits in the ruins of his lair, observing the Martian Manhunter from afar.
