This is what we know of Jim Kirk from TOS.
Has a brother George whose death he wasn’t exactly broken up over.
One of the youngest to ever make Captain
Survived the Kodos incident and was there at a young age.
Was a “Book with legs” at the Academy. In his class you either think or sink.
Nearly married a blonde at the Academy (Probably Carol Marcus)
Won diplomatic awards.
Never mentions his parents. This all tells me he was a self-made man driven by himself to always win.
Yes, he will seduce women to get information (See Catspaw and Conscience of the King)…and not terribly convincing since in both of those incidents the women saw through his ploy. A horndog who will sleep with anything that moves? On the contrary he’s poor at relationships. His Indian wife dies. Joan Collins dies. That android he fell in love with (WTF writers…i’ll fanboy that away as the effects of the virus and Flints adeptness at making androids) died. His marriage seen in Generations wasn’t succesfull. Carol told him to stay away and so he did.
