This article is about the player character Sergeant Peters. For Peter Plum, see Professor Plum.

Sergeant Peters is the Player Character in Chess. Peters' gender, race, appearance, and even personality are all customizable by the player. The male version of the character (known by fans as Male!Petes) is voiced by Troy Baker, and the female version (nicknamed FemPete by fans) is voiced by Laura Bailey.

In most endings, Peters ends up dead; however, with a high enough Readiness Score, Peters is shown to take a breath in a post-credits cutscene.
