Sergio can change the Courier's hairstyle, hair color, and facial hair. He is recommended by the King himself once the Courier gains membership to his gang.
The Courier can only take advantage of Sergio's services by joining the Kings, which can be done by completing the Kings quest-line and gaining the King's one favor.
Sergio is one of the only two non-player characters able to change the Courier's appearance in-game after Doc Mitchell; the other being The Sink's Auto-Doc.
Attacking Sergio will not turn other Kings members hostile.
Playstation 3Xbox 360 Sometimes Sergio isn't there. He cannot be found anywhere in the building, and exiting and re-entering doesn't seem to help, nor does waiting. He appears only after the Courier has killed a significant number of Kings and the King himself. [verified]
