Can X-Man use Telepathy and other mind powers. Or is he just limited to Telekinesis?

x-man when he was alive was the most powerful telepathic/telekenetic ever

"x-man when he was alive was the most powerful telepathic/telekenetic ever"

he was the most powerful psionic ever...no psychic on Earth could f*** with him

"he was the most powerful psionic ever...no psychic on Earth could f*** with him"

Plus X-man could combine his telepathic/telekinetic powers @Nisk5:
wait afew weeks & he'll be back .

The ending to Dark X-Men did piss me off. It did make sense  sort of how it ended up going down though. The whole Mimic/Omega power siphon thing, essentially would be a siphon powerful enough to drain even Nate, when you consider that it would really just multiply between the two of them to the Nth degree. Does bug me now though that after that, he's not made mention of in the marvel universe. But he is joining the X-Men in this new series so hopefully he makes a more permanent addition to the team.

And as for WHAT his powers are, his core powers are telepathy and telekinesis. On top of that he is a precog, which he has gained serious control of. Ultimately he is the ultimate telekinetic, it's what all Nate Greys on all worlds have been according to Evil Queen Jean. And he has overpowered the one of the most powerful of psychics on a whim so that would make him the ultimate telepath as well. Of course by ultilizing these powers in just the right way, there is very little Nate cannot do. He's telekinetically manipulated the Earth's magnetic field to create an EMP. Bent the very walls of reality to move between worlds and walk across the spiral of realities as no other has. He can use his powers to induce healing and shut off the pain receptors in his brain. He's taken hits that killed an alternate reality Thor and destroyed the planet Earth itself leaving Nate only unconcious. He has the innate ability to hide from detection even from Xavier with Cerebro. Broken through powerful telepathic blocks like they were tissue paper. Destroyed cities in his sleep. And before Dark X-Men he overloaded and overwhelmed anyone who tried to drain or feed off his power.

X-Man is the most powerful esper in the entire multiverse. Imagine Cable, Stryfe or the Dark Phoenix without the limitations or the evil intent.

Is X-Man more powerful than Onslaught?   More powerful than an Omega-Level Jean Grey?  More powerful than Omega-Level Jean Grey as The White Phoenix????

Odd that they depowered him. I've heard the notched down to even out with the other team members thing, but they handled Illyana fine, so I don't see it.
I hope there ends up being a good reason for such an out of left field move. I liked reading him with jacked-up abilities, I thought it was interesting.
 
@QuasarPrime: 
Nate wasn't that far behind in showing in the 2000's either, especially in Dark X-Men, the stronger point being he didn't need to rely on a cosmic entity as his power source, hence his title.
