The animated short "Mech My Day", a non-canonical LEGO production, was launched on October 10, 2023. It is a part of the LEGO STAR WARS: Celebrate the Season collection.
Inside Fortress Vader, a stormtrooper is shown applying oil to Darth Vader's helmet. While polishing it, he mistakenly drops it from Vader's head. This infuriates the Sith Lord, who uses a Force choke and telekinesis on the stormtrooper. The stormtrooper then places Vader's helmet on backwards, leading Vader to again Force choke the stormtrooper and throw his fellow soldiers to the ground.
Incensed by Vader's aggressive behavior, the stormtrooper proceeds to a garage and assembles a mech walker. He then confronts Lord Vader in the throne room, which excites the other stormtrooper guards. Vader's response is to use the Force to construct his own mech walker. The rebellious stormtrooper and Vader then begin to fight using their mech walkers. Despite Vader's mech being smaller, the two combatants are evenly matched. Vader eventually gains the upper hand and starts punching the stormtrooper's mech repeatedly. During their battle, Boba Fett is seen flying past the window in his starship, the Slave I.
As Vader and the rebellious stormtrooper begin a second round of fighting, Fett enters the throne room in his mech and knocks both of them to the ground. He declares himself the victor, but Vader and the stormtrooper get up and try to attack him. Fett's Mech escapes by using a jetpack to fly through the ceiling. Vader and the stormtrooper then emerge from the wreckage. Vader then Force chokes the rebellious stormtrooper for the third time.
