Here is John Adder, my Fallout 2 character. Part time Enclave Recruit, Part Time Mob Enforcer, Part Time Porn Star, Part Time Brotherhood of Steel snitch, Part Time Shi killer and Thief.
He dreams of joining the Enclave, but will have to settle with stealing their armor and killing them.

(He's also outrageously rich.)
I would play the same character through all the games like I do with Elder Scrolls, but I just stuck with remaking characters like James Bond and Max Rockatansky in FO4.
