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 for "easy pickins," 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 may be difficult to defeat at lower levels. If the Sole Survivor found Sully's journal holotape, they can discern he was already a Raider.

His new model will also sport a facial tattoo, possibly in relation to the Taboo Tattoos magazine in the area.

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.

Behind the scenes
Sully Mathis is voiced by the same voice actor as Garrus Vakarian, from Bioware's Mass Effect Trilogy.
