Nathan (Fallout 3)

Nathan (00003b57) is an elderly citizen of Megaton. He believes all the Enclave propaganda he hears on the radio, and openly praises them. Nathan promises the Lone Wanderer that although he is considered by many to be a senile old man, that "things will be different when the Enclave gets here". However, Nathan's foretelling never actually transpires.

Nathan later appears as a Corpse near to the bomb, dead for no apparent reason and Manya laments his loss.

Once you are captured by the Enclave, Nathan's decapitated body is in the cell to the left of yours. He has a key for "Nathan and Manya's House" on him, so it is likely this is really Nathan and not an android made to look like Nathan.

NOTE: In my experince Nathan appears in the Enclave base alive and well in the cell, saying " Run now, their not who they say they are! " You can't make him follow you niether can you talk to him at all, you can interact with him and he will say the above phrase.

Appearances
Nathan appears only in Fallout 3.
