Robert Joseph MacCready

Mayor MacCready is the mayor of Little Lamplight. He is a young, profane-mannered child with a no-nonsense attitude. He is armed with an assault rifle, and when the Player and MacCready first meet, he threatens to "blow your fuckin' head off." Despite his threat, he won't attack you when provoked. He'll simply run away shouting, "Every man for himself!"

MacCready came to power shortly after the five-minute rule of Princess. According to Sammy, when Princess demanded the title of Mayor to be changed to Princess, MacCready punched her in the nose and said that the children of Lamplight needed a leader, not a princess. He was then elected to Mayor.

Lucy directs you to talk to MacCready if you want to trade for some Cave Fungus, which is a radiation medicine and food. MacCready will make you a deal to trade it for Buffout or Strange Meat if you have the Child At Heart perk, or if your speech is high enough, he can be intimidated into giving you his private stash of 10 fungi. (You will lose karma for this option, and he states that you shouldn't expect any good will in town after that, and he no longer discusses trading for more and none of the other occupants will trade with you.)

MacCready cannot be pickpocketed.

Bugs
Mayor MacCready is prone to disappearing when you need him to continue a questline. Others have reported that he tends to wander into obscure and dark corners. It may take a great deal of time to find him again (if you can at all) without resorting to the command console on the PC. The relevant PC console command is player.moveto 0000313B

While this may or may not be a "bug", it is advised that you get him to open the back gate during your first conversation with him, so seeking him out a second time is not required.

Seen this happen to a few people on various related forums...sometimes MacCready will not give you the option to open the gate, even if you are at that point and have followed the advice outlined in this wiki.

Appearances
Mayor MacCready appears in Fallout 3.

Behind the scenes
MacCready is referred to as "RJ" by Eclair in Little Lamplight. "RJ MacCready" is also the name of the main character/hero in John Carpenter's "The Thing." His personality resembles another character called MacReady who is also a mayor in the horror movie "Slither".

MacCready's physical appearance is that of the kid at the end of Mad Max Beyond Thunderdome. The kid is the son of the helicopter pilot from Road Warrior. Father, son, and the kids from the airplane crash site all fly off in his odd looking airplane. The quote "I'll blow your fucking head off" is exactly what the kid tells Mad Max and friends when he is "robbing" them.
