Captain Zao

Captain Zao is a ghoul living in the Chinese submarine Yangtze in 2287.

Background
Captain Zao is a former captain of the Chinese Navy. He is the captain of a Yangtze class Submarine; the Yangtze-31. He has been observing Boston for centuries, ever since the Yangtze hit a mine and became stranded. The rest of his crew are feral, but he cannot bring himself to kill them. He mentions that he has to fend off raiders at times.

Zao recalls firing his ship's nuclear salvo as ordered, though it is clear that he is responsible for the nuclear detonations specifically in the Commonwealth. He reflects on his actions with guilt, regretting the destruction he caused. It is possible that one of the nuclear warheads fired from his submarine was the one that created the Glowing Sea. He claims that the city was already ruined, when he arrived at the port.

He seems to consider the liberation of Anchorage "a joke". He is clearly aware of the war being over, but he still holds traditional values of the old world. He refers to the Sole Survivor as "capitalist" and "American".

Quests
Here There Be Monsters: The Sole Survivor can help Zao repair the Yangtze submarine.

Effects of player's actions

 * Should the Sole Survivor call Zao "commie", they will demand that he dies for destroying your country, and Captain Zao will immediately turn hostile and try to kill the Sole Survivor.
 * Should one help him repair the Yangtze's reactor, he rewards with homing beacons for small tactical nukes fired from the Yangtze, saying "I do not want to bring the fire home." Zao will also give the player the unique weapon Zao's sword, if all three Charisma checks asking for money are passed.

Appearances
Zao appears only in Fallout 4.

Behind the scenes

 * Zao is the first human character from pre-War China it is possible to converse with in the Fallout series.
