Jensen stands at 6'2" and is fairly well muscled from his time working as a mechanic. He has curly, light brown hair and dark green eyes. He tends to dress in clothes that he can easily work with and not have to worry about getting dirty or damaged.

Jensen is in his late twenties and grew up in the township of Quincy. As he got older he moved to Diamond City to be a mechanic and narrowly avoided the Raider attack that destroyed the settlement. Over the last few months he's been hearing about the resurgence of the settlement at Bunker Hill and moved there in late November.
