Banshee

 Banshee is the leader of the savage and cannibalistic Jackals in 2253.

Background
Banshee is strong, perceptive, tough and looks more sinewy than bulky. He's going bald, but he doesn't know why; maybe he ate something bad. He's taken it out on his wife and kids. He killed his previous wife for accidentally burning his hair.

One month prior to the arrival of the Prisoner, guerilla warfare drove Larsen's men into the mountains, slowly starving one of his men snapped and had to be killed. Larsen offered the body to Banshee and an uneasy alliance formed between the Jackals and the Baggers. By the time the Prisoner arrived at the Boulder Dome, the unsteady alliance between Banshee and Larsen has left them in a Mexican standoff, as both want to get in to the Dome and neither wants the other to live after that. 

Quests

 * Destroy the Jackals: As the leader of the Jackals, Banshee must be dealt with. Driving them off is not necessarily going to work as they often retreat anyway, killing him and the rest of the Jackals is the only way to guarantee their demise.

Other interactions
If the Prisoner is female, they can have sex with Banshee.

Appearances
Banshee was going to appear in Van Buren, the canceled Fallout 3 by Black Isle Studios, and the canceled Fallout: Brotherhood of Steel 2.
