Personality: James Kirk is the sort of person nobody lacks an opinion of: he is loved, hated, or regarded with some masochistic mixture of the two. Nevertheless, his personality – strong, hard-headed, resourceful, loyal, and stubborn – begs to be opined. In a professional setting, he can be called upon as an intelligent mind, possessing higher than average IQ, but is best renowned for his leadership and tactical skills. He has a gift for computer hacking, xenolinguistics, and mathematics, among other things, but his passion is in proving others wrong when it comes to his abilities. To put it simply, he doesn’t believe in no-win scenarios or anything being "impossible." That word simply means he has to be a little more creative in going about solving the given problem. Perhaps the strongest evidence of how strong his faith when it comes to this is the Kobayashi Maru. It’s a computer simulation given to Starfleet cadets to A) practice their bridge skills and B) coerce them into showing level-headedness even in the face of certain failure. Jim, already haven taken the test twice, took it a third time and had an unwitting accomplice install a subroutine in the program. He’d won what no one else had, because he wasn’t afraid to change the circumstances to be in his and his crew’s favour, no matter what the cost. This is a trait he looks for in the people he surrounds himself with, namely, his crew. The Enterprise, throughout her first rescue mission and subsequent, impressed again and again by doing things she oughtn’t have been able to do. While individual crew members were obviously a factor in this, Jim is their unifying force, the thing that brings them together and tells them to forget about the laws of physics and just do what needs to be done. This is something Jim both loves doing – motivating – and is great at doing. He can be critically supportive or switch to more gently so on a whim, wanting simply what’s best for those around him and the universe at large.

This resoundingly strong personality tends to carry over into her personal life, translating into charm that few bother trying to resist. He’s a flirt, by every definition of the word and people tend to fall for him, if only for the evening. Socially, he enjoys drinking, sex, poker, and if the situation permits, a good bar brawl. But not necessarily in that order.

Other: Jim has an assortment of rather severe allergies, including to most types of nuts and numerous vaccines. As a result, it is strongly advised no one give him medicine without express permission from his CMO. And for "strongly", "on pain of death" could be humorously exchanged.
