I <3 Ikaris, but no. Martian Manhunter is stronger, the greater telepath, and overall more powerful. Ikaris makes him work for the win but MM will take it.
Do you think J'onn is stronger than Namor? I'd place him very near that range of strength imo. I can't see anything cut and dried about MM beating Ikaris and see this as an extremely tough fight for either of them
Even if Ikaris could win the physical confrontation on stamina and have a similar strenght level MM's shapeshifting still gives him an edge over all imo.
The telepathy really throws the rest of the battle off the loop.
Yes, IMHO, MM is stronger than Namor. Just recently AM and Mera couldn't handle MM physically and had to result to weakness exploit to bring him to his senses. Like I said, Ikaris would give MM one hell of a fight, but in the end MM would win.
Namor would be able to hold off Mera and Arthur as well if we're talking about a pure physical confrontation. Namor is one step away from being one of comics super heavyweights... kind of like J'onn.
Don't ever sleep on Namor, because he doesn't really have a horrible record against any particular character, and if he has been beaten with ease, it's come at the hands of a Thanos type powerhouse, or through weakness exploitation.
Either would take this on any given day, because J'onn isn't taking this without being severely injured.
Namor is not holding off Mera and Arthur at the same time. Each of them individually have given Wonder Woman a hard time in a brawl.
Namor does have respectable super strength and fighting ability but his stamina and durability (especially out of the water) is suspect as phuck. That's what holds him back. MM would maul him physically (and that's not even taking into account MM's more exotic powers).
Ikaris would do much better than Namor vs MM because he can at least counter some of MM's powers.
Namor probably has superior relative physical strength showings in both number and quality compared to Martian Manhunter.
I say relative, because the only thing he can't match, would be Martian Manhunter/Superman/Diana moving the Earth briefly, but he also duked it out with Hyperion, in the same story they referenced him stopping two planets so I don't think that's a deal breaker.
Martian Manhunter's heat vision(?) might seal the deal I guess..
Namor has a long history of resisting fiery attacks well and absorbing energy ones... not that it matters, because J'onn is too f*cking dumb most of the time to even remember he can emulate HV with his filthy alien eyes.
Telepathy seals the deal on this one. And MM is strong enough to compete. He aided superman in stopping Brainiac's ship, which was a lot bigger than earth.
