I think Mewtwo would be pretty much immune to telepathic assault...and when it comes to 1v1 combat...well...I don't think Charles h2h skills would match up to Mewtwo's other attacks.
Thanks for reading,
what telepathic assault did he get through to make you think he is immune? Emma was supposed to be immune to telepathy period, but Xavier is/was one of the few telepaths powerful enough to disprove that theory.
In order for mewtwo to use his more powerful psychic attacks he must remain motionless to concentrate,,in that time X would be invading its mind and destroying him mentally...I'm going with the professor
Lol what? No he doesn't. I saw that movie when I was a kid man, he was using psychic power while moving, even while flying around.
That being said, while Mewtwo is stronger on paper, I don't think they've shown him using serious telepathy and doesn't have the feats to back it up. So Xavier wins.
