During the events of the clash on Nevarro circa 9 ABY, Moff Gideon was seen with a battalion of stormtroopers from his Imperial remnant; this included his personal death trooper guard, who acted as his protectors. This battalion engaged in combat with the Mandalorian bounty hunter Din Djarin and his comrades in front of a Nevarro cantina, ultimately compelling them to withdraw into the building. Gideon then commanded an incinerator trooper to flush them out with fire, but Din Grogu employed the Force to reverse the flames. Djarin and his group then fled into the sewers, and despite being hunted, they ultimately triumphed over Gideon and his entire contingent.
The initial appearance of Gideon's battalion was in "Chapter 7: The Reckoning". Its designation as a battalion was confirmed in the audio descriptions for "Chapter 8: Redemption."
