Telepathic immunity

Telepathic immunity is the ability to resist psionic communication and/or attack. This power is actually common amongst psionics themselves, for they may require it to fend off mental attacks from another psi. The ability to resist an attack is dependent upon the user's mental fortitude in contrast to the psionic strength of his or her opponent.

There are some alien races who possess this ability as part of their natural biology. In the Star Wars mythology, both the Hutts and the Toydarians seem to possess a small degree of psionic immunity, which is to say, there have been examples of such beings being able to resist the effects of a Jedi mind trick. The gangster Jabba the Hutt once told Luke Skywalker that Jedi mind tricks would not work on him. Whether this had to do with Jabba being a Hutt, or whether he was merely bragging about his own willfullness is unclear. The Toydarian Watto expressed a similar point when Qui-Gon Jinn attempted to haggle with him for parts to a starship.

Another race that can resist mental attacks are the Saurids. They are an amphibious reptile race featured in titles published by Marvel Comics and are represented through the character of Ch'od. Ch'od's Saurid brain enabled him to "barely feel" a telepathic assault from the Cancerverse Xavier construct that had the entire Imperial Guard bleeding from the eyes and nose.
