Biography
J'onn J'onzz grew peacefully on Skrullos alongside his wife M'yri'ah J'onzz and daughter K'hym J'onzz. However, it all changed when the Outriders arrived on the unprotected planet, killing most of the population, including all of J'onn's family. He was the last survivor, but was spared when the invaders saw they could use his power to harness the energy of the Tesseract for their master, Thanos.

He was enslaved, and would be brought in Leviathans during any planetary invasion. J'onn always attempted to use his telepathic powers to communicate with the races, but always failed, until they invaded Earth, and he was able to communicate with the heroes assembled by S.H.I.E.L.D.. When all of them arrived - Superman, Iron Man, Batman, Wonder Woman, Thor, Flash, Green Lantern, and Captain Marvel, J'onn revealed the nature of the Outriders, revealing they had to finally put their differences aside to stop their threat.
