Super Strength: The Martian's superhuman strength comes from his plasmorphic structure formed from immensely long and complex molecular chains, augmented with his psionic and telekinetic abilities allowing him to lift incredible weights without these weights crumbling under the stress. The Martian has been seen lifting small tankers out of the ocean for short distances. By modifing the density of these bio-polymers, the Manhunter can make himself stronger by forcing the polymers into tighter bundles. At a rest state, the Manhunter can lift approximately 20 tons. Given a few minutes to reconfigure, he could match Superman pound for pound for about a minute. Then the bio-polymer would begin to suffer under the strain and begin to unravel. While the Manhunter's strength can be on par with Superman and he lacks the long term endurance and stamina of the Kryptonian. This probably has to do with the Kryptonian's storage and creation of MetaATP which the Martian biology would not have developed being so far from the Earth's sun.
Limited Invulnerability: The Manhunter's invulnerability is no where near what Superman's is, as proven by the battle against Doomsday. Doomsday, defeated the entire Justice League with a single blow for each member. Overall, the bio-morphic structure of the Manhunter's body allows him to absorb most kinetic energies such as bullets, shrapnel or flying debris. Attacks of a nature greater than that, he can harden his bio-polymers by rebinding them and become nearly 10 times as resistant to damage as steel. Hazardous environments effect the Manhunter less than normal humans and he seems to recover from them much more quickly. He has proven to be immune to most human diseases, but no experimentation has been done to see what more advance viruses such as ebola or anthrax might have.
Superman is above him in terms of strenght, endurance, stamina and resistance to injury, and speed.Martian Manhunter doesn't possess superspeed, that would be the fundamental power for Supes in this fight.
Plus he can stay toe to toe with Supes for about 1minute, not more.
Want to talk about his Martian Vision?Nothing that Supes hasn't take before without effort.
You wanna put against Supes a strong member of the JLA?
Pick up Orion.That would be a great fight
Super Strength: Orion's primary ability is his superhuman strength, invulnerability, durability and hardiness. Orion is the son of Darkseid and is the second most powerful person ever born on that world after Darkseid. His physical strength is difficult to gauge accurately, but he has fought Superman to a standstill several times in direct physical conflict and has successfuly beaten Darkseid at least once. He is possibly the most powerful humanoid on Earth today. No normal Earth-made barrier or substance can possibly stop Orion if he wishes to enter an area. Few barriers, even in the Fourth World are capable of stopping Orion. Battles that have had Orion at the scene are known to be catastrophically destructive and often have extreme loss of life.
Endurance/Stamina: Orion's stamina is legendary. Only on Apokolips or New Genesis, are there any beings with the ability to compete with Orion in a conflict of any nature. Bolstered by his rage and his mother box, Orion is a virtually inexhaustible engine of destruction. This does not mean that Orion does not tire. In battles against foes of near equal might, such as Kalibak or Darkseid, Orion has been seen to fatigue, only after hours of continuous combat. The scale at which these beings operate is well above what we have come to expect from terrestrial metahumans.
