J.J. Carter

Seasoned officer whose entire family was executed by a Klingon raid on their colony. Later joined Starfleet but harbors and suppresses violent feelings due to his anger of losing his family. He has some how managed to keep this and a stimulant abuse problem hidden while steadily climbing the ranks. Very affable and charming, and a decent surgeon. Makes friends easily. He is having an affair with a young married crew member. Her husband does not serve on the same vessel. Secretly wants war with the Klingons to continue indefinitely so he can satisfy his thirst for revenge. Despite all this, deep down he is still a decent person who lost his family and wishes his life had turned out differently. Will do anything to patch up his crew, but Klingons....
