Mister Lopez

 is a 65-year old suicidal resident of Rivet City in the year 2277.

Background
According to the Fallout 3 Official Game Guide, his wife and child were killed by raiders, and he has fallen into a depression ever since. This is probably the cause for his suicidal behavior.

Interactions with the player character
Lopez considers committing suicide due to the fact that no one remembers him or even cares about him (also learned by talking to him on the Flight Deck that he couldn't save his family.), but he doesn't have the courage to do it himself. You can find him on the flight deck at the top of bridge tower every day from 8:00 - 12:00 and 15:00 - 17:00. You can:
 * Help him to commit suicide by pushing him off the deck (negative karma).
 * Talk him into committing suicide by saying he's pathetic (negative karma).
 * Use speech to convince him that Ted Strayer needs someone to give him guidance and that Lopez is the one to provide it (positive karma).

Appearances
only appears in Fallout 3.
