Darth Bane is highly resistant to mental influence:
Darth Bane easily resisted Kaan's telepathic influence, which has manipulated thousands of highly mentally trained Sith Lords. Even Kopecz, a Sith Lord with enough willpower to continue to fight with a dozen arrows in the back of his neck and two spears skewered through his chest, wasn't entirely immune to Kaan's influence. Kaan could also telepathically call out to all 20,000 Sith Lords in his order, a feat only accomplished by himself, Luke Skywalker, Exar Kun, and Darth Krayt.
Bane stayed in the position of supplication until the Dark Lord was well out of sight, then stood up and brushed the dirt from his knees with a grim scowl. He had felt Kaan's efforts to dominate his mind, but they had had no more effect than a rusted knife scraping against the hide plates of a Halurian ice-boar. Yet he had seized on the opportunity and delivered a performance worthy of the greatest dramatist on Alderaan. - Darth Bane: Path of Destruction
