M'yrnn J'onzz

"But, like my father said then, there is great power in being the calm at the center of the storm, a beacon to show the way."

- M'yrnn's son, J'onn

M'yrnn J'onzz was the former high religious leader of the Green Martians, and the father of J'onn J'onzz.

Biography
M'yrnn J'onzz acted as the high religious leader of the Green Martians. One day, he left worship early in order to surprise his son, J'onn, on his birthday. He entered his home to find his granddaughters, K'hym and T'ania, who were aware of the plan. J'onn walked in, happy and thankful to see his father.

Attack and imprisonment
Sometime following, the White Martians launched an attack on the Green Martians, killing nearly all of them. M'yrnn was taken as a prisoner, kept alive by the Whites due to their religious zealotry that prevents even the most heretical of them to strike down someone of M'yrnn's bestowed title and former standings. Instead, he was tortured for information and tricked by his captors for hundreds of years, as they wanted to gain his intimate knowledge of their planet's history and relics, namely a powerful and legendary weapon that was long thought to be a mere myth. However, in captivity, M'yrnn held strong.

Rescue and reuniting with J'onn
He eventually found himself in a base that was stormed by rogue White Martians, taking him to safety. By then, in some other way, the more malevolent Whites have found the weapon's location and prepared to excavate it; and having left with no other use for M'yrnn, they left him detained and alone which led to his rescue from bicentennial imprisonment. Though M'yrnn believed his rescuers' well-intended cause, he adamantly refused to reveal the weapon's whereabouts.

At their underground hideout, M'yrnn was visited by his son, whom he had believed to have died. Due to this, he believed it to be a trick by the White Martians in an attempt to find the location of the Staff of Kolar. J'onn tried visiting again, this time in his human form, causing M'yrnn to take a human form out of custom. He explained the lore behind the Staff of Kolar, and in turn why he zealously refuses to allow either faction of the White Martians its use, as gaining the Staff would mean the Whites warring upon each other to the point of extinction, the way they did with nearly all of the Greens. However, this was interrupted by Kara Danvers after the White Martians decided to take the information by force. They escaped, taking M'yrnn back to the two Martians' former home. Finally, M'yrnn admitted, he had been broken, a feat no White Martian had ever accomplished. As M'yrnn went to pray, expecting death as an inevitability, Kara interrupted, asking him to acknowledge her as a Kryptonian, thus trustworthy, and to give J'onn a second chance. M'yrnn allowed J'onn into his mind, the latter showing M'yrnn his favorite memory, in which M'yrnn had surprised J'onn by leaving worship early. Finally convinced that J'onn was truly who he said he was, they were interrupted by the rogue White Martians. M'yrnn gave them the location of the staff. After the Staff of Kolar was procured, Till'all decided it best to entrust it to their Earth allies. J'onn and Kara headed back to Earth, taking M'yrnn with them. Arriving back on Earth, M'yrnn admitted to quite liking the planet, being amazed by a weed growing out of the ground. Kara soon left them, before the two Martians walked to J'onn's earthly home.
