SPOILERS!Below is information that may adversely affect the reader's enjoyment of the game.
The Watcher is an alien entity of Eridian origin.
Next to nothing is known about this being, even to the extent where "The Watcher" is only a title. It has demonstrated a telekinetic ability and knowledge of future events. The being has appeared to certain individuals often forewarning them of danger, although its motives for helping remain unknown.
The Watcher first appears on Helios when Jack and the Vault Hunters attempt to escape by ship. When Jack tries to shoot at Zarpedon, it blocks his shots telekinetically before mocking him. The entity is not seen again until the very end of Borderlands: The Pre-Sequel when it saves Athena from being executed by Lilith and the Crimson Raiders. Afterwards, it warns the vault hunters of an imminent war for which they will need to recruit as many vault hunters as they can.
- The character has its own title card, but its name is written in an alien language and is only accompanied by the text "...?"
