It always strike me that some x-men could really be much more powerful if they fully used their powers, going beyond what is acceptable in comics and could really wipe the floor with most adversaries...
Some mutant like Cyclop are quite straight forward with the use of their power, aim and shot, you hit or you miss...same for Wolverine, beast or angel, you get close and hit the target...
But Mutant like Kitty Pryde, jean grey, Emma frost and other are quite different.
Kitty could virtually phase out brains, make the ground phase and solidify on adversary...
Jean could give a good TK squeeze on male private parts, and have all male adversaries on their knees without much efforts, she could close their eyes lid and block ears drum and make all opponents useless, all of this without much of a strain considering how much she can lift with her TK...and here we are not talking about killing your opponent but just easily neutralise them...in life and death situation why not use all your arsenal? Morrison was the only one to have Jean use her Tk in a more lethal way when she faced the U-MEN.
Emma as well could use her TP in a lot of way, once again Morrison was one of the writer showing a more perverse use of TP when she made all those reporters have an orgasm!
Which other x-men could potentially be very powerful if he was using his power fully?
