First Order stormtrooper executioner

The role of First Order stormtrooper executioners, also known as First Order Judicial Stormtroopers or Executioner Troopers, were First Order stormtroopers randomly selected and assigned to dispense final justice on First Order soldiers found guilty of treason.

History
Owing to the First Order's merciless attitude towards treason, trumping even that of the Galactic Empire where even a derogatory remark was considered treasonous, the First Order stormtrooper executioners tended to do several public executions on anyone with even slight loyalty issues each day. In addition, the stormtrooper executioner underwent several rotations during each session, and was even considered at times a test to see whether they will make it within the Stormtrooper Corps. They are trained to deal with anyone disloyal to the First Order.

Prior to his defection from the First Order, Finn undertook executioner duty, hoping each day would end without having to carry out any executions.

After Finn's defection to the Resistance and subsequent capture aboard the Supremacy, two of these were brought out by Captain Phasma to execute Finn and his companion Rose Tico, deeming an execution by blaster to be "too good for them". The two selected prepared to dispense justice upon them and prepared to behead them on Phasma's command. Right as she gave the order, however, the Supremacy was suddenly devastated by Vice Admiral Amilyn Holdo's suicide maneuver when she rammed the heavy cruiser Raddus into the Supremacy at lightspeed. The two executioners, along with the majority of those gathered in the hangar, were killed instantly in the devastation.

The First Order stormtrooper executioner were created for the 2017 film Star Wars: Episode VIII The Last Jedi, directed by Rian Johnson. The executioner was first officially revealed in behind the scenes footage from The Last Jedi at the D23 Expo in July 2017.
