Can Martian Manhunter defeat the Warlock? This is normal Warlock, against an ticked off Martian. Keep in mind, MM has taken out the whole Justice League before, so could MM defeat the Warlock?
The scenario: This battle will take place in space, since they both don't need air to breath, it'll be a perfect battleground.
Here are the stats of both warriors:
Adam Warlock:
VS.
Martian Manhunter: You can go here to look at his stats.
The only chance MM has to engage the Warlock in Physical battle. MM is probably physically stronger. Cause no telepathy assault is going to work on Warlock. Unless MM's telepathy is on par with Exodus, but most likely not. Telepathy will not work here probably for both opponents. Can MM take a few hits from power cosmic?
Martian Manhunter is considerably better than Xavier. He is said to be by far the most dangerous member of the JLA. The first statement was according to Superman, who said that there are around 5 people in the universe he would rather no fight, and that the Martian Manhunter was at the top of that list. Green Lantern also said the same thing, that MM was basically the most lethal individual on the entire planet. And the Guardians of Oa basically stated the same thing (note: we’re talking about the guardians of Oa here).
MM basically, in a bid to find out who was responsible for an act of atrocity, turned himself into a tree (he is a shape shifter) and touched the minds of every single person on earth. In seconds. Without the aid of any machine!
He can basically reach any person on earth AS WELL as the moon. His range may be further than that, but the maximum range written down in a comic is basically the entire earth plus the moon.
Jjon Jonz also reached out and forced world peace (Israelis became bossom buddies with Palestinians), lobotomized all criminals in the globe (including Lex Luthor), and once he had gotten totally carried away by his evil side mentally controlled the military to launch nuclear ICBMs.
Not only is he telepathic, he is also an empathy of a high magnitude of power. For example he has sensed things that the only other person who could was the Angel Zauriel. Is telepathic abilities are just not human (after all, he himself is NOT human).
The main thing about Jjon Jonz is that he is a pacifist. When (in JLA: Trial by Fire) he let go of his pacifist nature and became his TRUE self, he basically defeated the entire JLA, killed off all the White Martians by himself, nuked a city, and almost destroyed the world.
There is also a telepathic attack that all Martians have that is supposed to be unstoppable. However this would not be a factor since it can only be used once, and MM already used it back in his homeworld.
Conclusion: MM is far more powerful than Xavier. Even if Xavier has Cerebro/Cerebra it would make little difference.
And one more thing (and this is of particular importance here).
Xavier has problems touching the minds of shape shifters. For example Mystique is largely invisible to him due to the fact that her mind is in a state of flux.
Guess who is the JLA’s number one shapeshifter: Plastic man, ofcourse.
Well, guess who is number two! Martian Manhunter!
