Sid (Fallout 3)

 is an insane human in Vault 87, also known as Subject C376. He is trapped in Isolation Room 03.

Sid is armed only with a lead pipe, but he has an abnormally high amount of health (seemingly more than a Super Mutant Brute). This may be due to some form of unique mutation caused by FEV experimentation on him (or he may simply be a "boss" enemy, like Commander Jabsco, the Vault 106 Survivor, Hubris Comics' Mad Johnny Wes, or Vance). He also wears a Merc Grunt Outfit.


 * (This is possibly a bug within the game) If the door is unlocked with a Bobby Pin, Sid is friendly but uncommunicative, screaming:
 * No! It's all over me! I can feel it... it's invading my mind!
 * Get out of my head! Get the FUCK OUT! Aaaaagh!
 * Can't you SEE?! They're all dead! It's all my fault!
 * If the door is unlocked by hacking the terminal, then Sid will attack you.
 * When the door bolts are blown, Sid turns hostile; even if the door was previously open.
 * If you free Fawkes by activating the lab's emergency fire systems, this will open all the other isolation rooms, freeing both Sid and a Centaur. Although both are hostile towards you, they will also attack each other if they spot each other before spotting you.
 * If Sid exits the room by glitching through the door (by walking against it until he is forced through) he will also be uncommunicative(see above).

In the construction set, there are dialogue options telling that he killed all of the people in his isolation room and that he may have been captured by super mutants.
