What weapon does Moff Gideon use in the Season 2 finale? He uses the Darksaber.

In "Chapter 16: The Rescue," Moff Gideon attacks Din Djarin with the Darksaber while Grogu is held aboard Gideon's Imperial cruiser. Din defeats him in combat and takes the weapon, although he does not initially understand that possessing it gives him a potential claim to rule Mandalore.

The Darksaber is not an ordinary lightsaber. It is a black-bladed weapon created by Tarre Vizsla, the first Mandalorian inducted into the Jedi Order. Because it carries deep cultural and political meaning, Mandalorian tradition says it should be won in combat rather than simply handed over. This becomes a major source of tension between Din and Bo-Katan Kryze.

Viewers sometimes choose "lightsaber" because the Darksaber is technically a lightsaber, but the quiz's intended canonical name is the more specific Darksaber. Gideon had previously been shown using it to cut himself out of his crashed TIE fighter at the end of season one, setting up its importance in season two.
