Fawkes is a super mutant and possible companion in Fallout 3 with the distinction of having retained his civility and
intellectual capacity through the rigors of mutation in 2277.
When the Lone Wanderer first encounters Fawkes, he is confined to Isolation Room 05, a cell in Vault 87 in which he has resided for as long as memory permits. Fawkes claims that he was able to attain literacy and a civilized
personality (things most super mutants sorely lack) by gleaning as much information as possible from the vault's immense online database (or at least until recently as
the terminal that he used was taken away from him). Fawkes credits his intimate knowledge of Vault 87 to being a resident there before being transformed into a super mutant, additionally he wears a Vault 87 Jumpsuit which is heavily torn, possibly due to his outgrowing it while mutating.
Lone Wanderer-"Fawkes, can u enter
the poison chamber for me?"
Fawkes-"It is not my
destiny"
Me-"WTF, u can survive this, and i still gotta die!!!"
