Bosun

The bosun is a Mister Handy aboard the USS Constitution in 2287.

Background
The bosun is a nearly broken Mister Handy that only has its head and thruster left. It has been reprogrammed by Ironsides to serve on the USS Constitution, having previously refused to adopt the mannerisms of the ship's crew and even regarded Ironsides as "balmy." When asked about its condition, the robot will tell the Sole Survivor that its limbs were lost during combat with the scavengers, a group of looters that are constantly at odds with the robot crew of the Constitution. This is problematic, as the bosun serves as the ship's mechanic. This causes the Sole Survivor's interaction with him.

Quests
Last Voyage of the U.S.S. Constitution: The bosun is one of two crew members the Sole Survivor is sent to assist in repairing the ship. The bosun is tasked with repairing the ship's aging electrical cables but is unable to do so because of its lost limbs. Because of this, it must be helped with replacing the fraying cables with new ones at three points around the ship.

Appearances
The bosun appears only in Fallout 4.

Behind the scenes
