The Martian who was thought to be J'onn J'onzz was the last of his kind before coming to the evil world of Earth 3. Finding peace with the villainous Crime Syndicate, J'onzz became deadly injured sometime prior to the Syndicate choosing to abandon their world once the Anti-Monitor destroyed it. J'onzz was rendered blind, missing both his eyes, and his right arm was decayed to just bone and muscle.
When Pandora was temporarily transported to Earth 3, she met J'onzz, who begged her to know if the other Syndicate members made it to the other Earth after having chosen to leave him behind, making him the last of his people yet again. The two were not able to talk long before the Martian succumbed to his injuries. 
- Martian Physiology: The average Martian possesses the potential for the following power set:
- Shape-Shifting: Martians have psionic control of their physical for down to the molecular level. This allows them to a form of shape-shifting that allows them to mimic other forms, elongate aspects of their body, increase or decrease their physical size, and so on.
- Invisibility: Martians can cause the biopolymers in their bodies to lose their ability to reflect light, making the Martians invisible to normal light and human sight.
- Phasing: Martians can go through solid matter.
- Superhuman Durability
- Superhuman Strength
- Superhuman Stamina
- Extrasensory Input
- Super Hearing
- Martian Vision: Martian visual acuity greatly exceed human norms and allows for a wider range of information to be observed. This includes the following:
- Telepathy: Martians have the ability to read the minds of others and project their thoughts to varying degrees. They can also project their mental essences into a gestalt community known as the "Great Mind". Through this, the community can enhance the telepathic strength of other Martians. This power can also enable them to reverse the effects of amnesia or psychological brainwashing. 
- Astral Projection
- Mind Control: As an extension of this, Martians can also use the ability to alter a psychological profile of a target, enabling them to manipulate, and in some cases, outright control that individual. This practice is greatly discouraged however, and only rarely used. 
- Telepathic Relay
- Telepathic Assault
- Vulnerability to Fire: Martians are much more vulnerable to fire than the average Earth human. At times this has been portrayed as physical, psychological, or a combination of the two. The effect of this is to strip any Martian of their powers as they involuntarily lose control of their body.
- Blind: J'onzz's eyes have been lost since before the Crime Syndicate left for another Earth.
