Sully Mathis

Sully Mathis is a character appearing in Fallout 4.

Background
Sully is a man, who came to thicket excavations for work. Happy he found a place to work, as well as a close trading line to buy supplies, Sully started checking the machinery. Since some of it stopped working, Sully bashed the machinery with a hammer, slightly startled, for strange noise was coming from it. The pipes started leaking, putting Sully out of business.

After the player character completes the Pull the Plug quest and leaves the quarry, upon returning after a while they will find that it has become occupied by a large band of raiders. Descending to the bottom will lead to a confrontation with a masked, well-armored Sully Mathis, who appears as a boss with a skull icon next to his name. Based on the fact that his player model sports a new facial tattoo, it is likely that he either fell in with the raiders when they attacked his excavations, or was already a raider and rose to be the gang's leader shortly after they re-occupied the quarry.

Quests
Pull the Plug: Sully asks the Sole Survivor to fix the pipes at the bottom of the irradiated lake. Once done, the Sole Survivor has to start the pump and fight off some mirelurks with Sully.

Appearances
Sully Mathis appears only in Fallout 4.
