During your quests, you might come upon a talking tree named Harold who regularly references a character by the name of Bob. Harold is a regularly occurring ghoul character in the Fallout universe who has appeared in all three Fallout games. In Fallout 2, a small tree begins growing out of his head, which he calls Bob. In Fallout 3 the tree has grown a bit larger than Harold can handle.

Cerberus

Ceberus is the robotic guard at the ghoul town of Underworld. His name references the guard dog from Greek mythology that guards the gates of Hades (i.e. the Greek "Underworld"). If you talk to Cerberus, he even mentions that he is the local "guard dog".

Raven Rock

Location Info (Wikia)

Raven Rock is the home of the Enclave in Fallout 3. However, it's named after a real government facility in Pennsylvania (see Wikipedia entry). Incidentally, Raven Rock was also the name of a location in the Bloodmoon expansion for Elder Scrolls III.

Guy Fawkes

Fawkes is another possible companion character in Fallout 3. He takes his name off the legendary Guy Fawkes, a man behind the Gunpower Plot, a failed assasination attempt on King James of England.
