The world’s most powerful telepath, Charles Xavier, is the mental counterpart to Magneto, but is flawed in many ways. Obviously, he’s not going to overpower anyone physically. His mental powers all have perception or extended range, so he can forgo making an actual attack roll to affect his targets. However, Xavier’s dynamic array is not wide, so he must operate each power singly or else lose effective ranks while spreading himself thin. Xavier’s Telepathy has the Rapid power feat applied to its Communication aspect, allowing him to communicate 100 times faster than usual—effectively almost instantaneously.

I’m not certain that Professor X really inflicts damage with his Mental Blasts, so Stun might be more appropriate. Xavier can also use Mental Transform to alter memories or as a power stunt to inflict mindwipes (as he once did with Magneto). Illusion can be a flexible power, and in addition to planting images into his subjects’ minds, he can stunt Concealment off of it.

Of course, Professor X can Detect Mutants radially, a power that is enhanced by Cerebro/Cerebra. In addition, his mental sense is Accurate, allowing him to use it to target Perception ranged effects in combination with ESP. Xavier’s Comprehend power is kind of a stunt he performs by probing a person’s language centers and copying their language abilities.

Yes, I know he can apparently walk again and is depowered, but we’ll see if either condition lasts.
Update 4/20/07 
Removed the Wide Extra from his Telepathy array and also lifted Astral Form from the array. He’s a perfectly balanced PL15 in terms of points, which for a psi like him, means he’s extremely formidable.
