This power allows mutants to immediately return any thought or mental attack directed at them, although it does not negate the effects of such attacks on themselves. A mutant with thought imitation is able, any time he wishes, to exactly copy the communication patterns of those creatures with whose thought patterns he is familiar, even if those creatures do not speak a language known by the mutant. Note: The power to return a mental attack is temporary. Once a mental blast has been returned, the mutant does not know how to repeat it. This mutant can, however, recall communications patterns at a later date.
