Mex

Mex is a Pitt raider guarding the gate to the Pitt around 2277.

Daily schedule
Mex and three of his men keep their guns trained on the road into town all day, ready to blow away any pests or vermin trying to get in.

Quests

 * Into The Pitt - Mex is The Pitt's gate guard and needs to be passed to enter the city.

Effects of player's actions

 * If the Lone Wanderer tells him they are a returning escaped slave, he will strip the Lone Wanderer of their inventory (except the "hidden weapon" possibly received from Wernher), give a slave outfit that is automatically equipped (whether the Lone Wanderer is wearing one already or not), and then tell them to enter Downtown.
 * If the Lone Wanderer tells him they came looking for work, he will sarcastically invite them to enter through the door to Downtown and fill out a "fucking application", whereupon the same happens as noted above; an ambush with items stripped (except the "hidden weapon"), and the slave outfit.
 * Killing him on the way in once again sets off the ambush, except there is different dialogue from the ambushers.

Appearances
Mex appears only in The Pitt add-on for Fallout 3.

Behind the scenes
Mex is a reference to the chain of Mad Mex restaurants, which are relatively popular in Pittsburgh, and the surrounding area like in Monroeville and Squirrel Hill.
