The Mandalorian Character Guide
Moff Gideon is the leader of the Imperial remnant and the primary antagonist of The Mandalorian. Few details of his backstory have yet been revealed. He was previously an operative in the Imperial Security Bureau, a covert intelligence arm and secret police for the Empire, and played a role in past efforts to eliminate the Mandalorians.
In The Mandalorian, Moff Gideon is attempting to abduct the Child to extract its blood for experimentation. In the first season, Gideon briefly traps the Mandalorian and his allies on Nevarro in an unsuccessful attempt to obtain the Child. Gideon reveals he knows secret details about the Mandalorian and his allies, and is the first character in the series to reveal the Mandalorian's real name, Din Djarin. In the final scene of the first season finale "Chapter 8: Redemption", it is revealed that Gideon possesses the Darksaber, a Mandalorian lightsaber.
Gideon returns in the second season as he continues to track down Grogu. "Chapter 12: The Siege" reveals that Gideon requires access to Grogu's blood, which contains a high 'M-count', for it to be transfused into a test subject. However, the experiments have thus far resulted in catastrophic failure.
Later in the season, Gideon apprehends Grogu and seeks to continue the experimentation, but the Mandalorian captures Dr. Pershing and infiltrates Gideon's ship. Gideon battles the Mandalorian with the Darksaber, but is ultimately defeated. As a platoon of Dark Troopers attempt to rescue him, Luke Skywalker arrives and destroys the droids. Gideon attempts suicide, but is incapacitated by Cara Dune. Grogu is taken by Skywalker to be trained as a Jedi.
