As posted in one of the other threads, I think Paul Atreides in Dune as INTP. He showed a lot of the typical traits, highly introspective thinking at all times, an innate intuition about the universe around him (to the extreme, in the end) and procrastination of important decisions. He spent the whole second book trying to delay the inevitable that he knew, for certain, would come to pass anyway. He also had a stubborn resistance to any form of external control placed upon him, though one might consider it ironic that he ultimately placed the control of prescience upon himself in so doing.
Grand Admiral Thrawn had some INTP traits (and some INTJ traits). On one hand, he was incredibly intelligent, with plans constructed and thought out to the most minute detail, tempered with an innate understanding of his enemies (through intuitive leaps prompted by the observation of art, of all things). Although one might be tempted to label him INTJ due to his ruthless strategies, they were constructed in a very different manner than most. I'd label him as an extremely well-developed, mature INTP. He also had a patience for slow-moving plans, something INTJs typically lack.
