-- J'onn J'onzz src

The last Green Martian. J'onn J'onzz had never been a violent man, but found himself drawn into what came known as "The Martian Holocaust", a war between the Green Martians and the White Martians. The war resulted in the death of his wife and daughter, along with both Martian races being entirely wiped out. J'onn J'onzz seemed to be the sole survivor of Mars.[1]

Some time later, J'onn encountered and befriended Jor-El. Through Jor-El, J'onn found purpose again. Working for Jor-El, J'onn brought criminals (both Kryptonian and criminals from other worlds) to justice, who were then banished to the Phantom Zone.[1] When Krypton was facing destruction, Jor-El asked J'onn to watch over his son, whom he planned to send to Earth. However, Jor-El had arranged for the boy to be put before tests. Tests that Jor-El wanted him to pass on his own. So, J'onn was forbidden to interfere, unless it proved absolutely necessary. Because of this, J'onn kept an eye on Clark from a distance, rather than interacting with him directly.[2]

After Clark accidently released several prisoners from the Phantom Zone, J'onn quickly found that he had no choice and had to interfere.[2] The first time occured in Seattle, when Clark attempted to bring down Aldar, only to be nearly be killed by him. Just before Aldar was going to kill Clark, J'onn rushed in and killed Aldar. Before Clark could ask him any questions, J'onn flew away.[3] The second time, that J'onn had to step in, was when another escapee from the Phantom Zone infected Clark's mind and trapped him in a nightmarish reality, in an attempt to get control of Clark's body. J'onn entered Clark's mind and was able to convince him of the truth. When the phantom was expelled from Clark's body, J'onn used a crystal to return it to the Phantom Zone.[4]
