Purge Trooper

There are actually multiple types of Imperial soldiers with the designation "Purge Trooper"

• The first kind of "Purge Trooper" appeared in The Force Unleashed as a variant of the Dark Trooper droids designed specifically to hunt and kill surviving Jedi and other Force-Users, such as the player character Galen Marek. Their heavy bodies and magnetized boots makes telekinesis ineffective, though their being droids does mean that they are vulnerable to Force Lightning.
• The second kind of "Purge Trooper" appeared in Star Wars: Uprising as heavily armored soldiers outfitted with rotary cannons tasked with eliminating any sign of dissent with extreme prejudice. A few have defected and can be recruited by the player.
• The third kind of "Purge Trooper" appeared in Star Wars Jedi: Fallen Order. They are the last clones of Jango Fett made, and are tasked with assisting Inquisitors in hunting down and eliminating Jedi who survived Order 66.
