They don’t have similar defenses, IIRC Gambit’s have been described in two ways before, one being that it’s hard to get a hold of thoughts(which was said in the scan on the previous page) and the other that his powers cause a kind of static which TP users have a hard time getting through. You have provided zero proof that Mr X can get through those types of defenses.
BTW, where is your proof that Wolverine’s TP defenses are superior to Gambit’s as they relate to Mr X’s brand of TP?
