J'onn J'onzz (Silver Age) was a Martian scientist transported to Earth in an experiment by Professor Mark Erdel, then stranded when the elderly man died from a heart attack over the shock of his success.

As "John Jones," the Martian served as a detective for a number of years on the Middletown police force in the United States, secretly aided by his alien abilities. Later, the Martian's presence was revealed to the world, and he soon after joined the new Justice League of America as the "Manhunter." The sorcerous Idol-Head of Diabolu artifact appeared to kill "John Jones," so the Manhunter abandoned that identity and began a lengthy search for the infernal device with his other-dimensional pet Zook. Once that task was completed, J'onzz was recruited to battle the international criminal organization Vulture under the cover identity of "Marco Xavier" while based in the Mediterranean. Finally, J'onzz unmasked their seemingly faceless leader Mister V, who then died in an explosion. This continuity was rendered moot as a false memory implant in a 1988 mini-series.

After Erdel perished in an explosion, J'Onzz used his shapeshifting and other abilities to explore his adoptive world. In the modern heroic age, J'Onzz assumed the form of a deceased police officer in Colorado, as well as countless other identities throughout the planet.

Zook was the otherdimensional pet/sidekick of the Manhunter from Mars in the hero's solo strip from 1963-1968, primarily in stories revolving around the pursuit of the Idol-Head of Diabolu. He was unusually helpful and intelligent for a creature whose sentience was questionable, including speaking in broken/unsophisticated English. Zook had the ability to generate extremes of heat and cold from his body, a modest degree of physical elasticity, and could remotely track any being to have come within a reasonable proximity of his antennae. Zook made a handful of appearances in recent years, including his seeming death in 2008's Ambush Bug: Year None #2.
Züm is a White Martian who pretended to be a humanoid with super-speed while attempting to conquer Earth with the Hyperclan.
