So apparently Martian Manhunter is a more powerful telepath than Xavier. How does he fare against Xavier's mummudrai - his evil twin - Cassandra Nova? No prep.
Cassandra Nova was a beast. But nothing MM can't handle. Nova was as strong as Xavier telepathy-wise so MM beats her in that department.
Or one blast of Martian Vision wipes her from existence. Besides Marvel telepaths for some odd reason cannot use their telepathy effectively against shapeshifters. And MM is a cream of the crop shapeshifter.
Cassandra Nova did a whole bunch of crap that Xavier cound never do and has a whole bunch of extra powers - psychokinesis, hyper-regenerative powers, intangibility, psi-plasmic armor, heat bursts, and the ability to analyze genetic codes then absorb them into "her" body - she can also technically call in a bunch of Sentinels if she wanted if I recall. She's never really did per se she regenerated from a dead pre-term fetus.
The only shapeshifter that I can recall can't be affected by Marvel telepathy is Mystique. Aliens, telepaths seem to affect just fine e.g. the Shi'ar by Cassandra Nova.

Yeah but the fact is MM is quite adept at blocking out his mind. And he can just phase through her body and scramble her mind. He's one of the top telepaths in any company.

Cassandra Nova. J'onn would have the initial edge due to speed, but given her hyper regenerative powers and the face that the battle takes place in character, there's not much of an argument that he'd speedblitz (or even speed-vision) for a win. Afterwards, if she's being taken physically, she can phase, heal, and dominate J'onn telepathically.
Cassandra nova isn't going to mind rape MM. MM is way more powerful TP than professor x.. the dude penetrated the mind of dr fate and freaking spectre. temporarily made the joker sane. he's one of the most powerful telepath in dc. if Mageddon couldn't mindrape MM, cassandra nova sure can't
And she's not copying his DNA either, Martian can alter their body structure and DNA.
there're so many ways for MM to kill her. like martian vision, or simply punch her in the face.
Manhunter will mindrape himself the minute he touches Cassandra Nova's mind. He's not navigating around those booby traps if Charles and Jean manifesting the Phoenix couldn't.
