Darthenshmirtz

"Darth Vader can kiss my bantha!"

- Darthenshmirtz, ending "Sith-Inator" Song

Darthenshmirtz is the main antagonist in the Phineas & Ferb Star Wars special. He's the Sith counterpart of Heinz Doofenshmirtz, and just like his original counterpart, Darthenshmirtz is somewhat incompetent in doing evil and is enemies with Perry the Rebelpus, the Jedi counterpart of Perry the Platypus. He's also a low-level employee working under the Galactic Empire and the lowest of all Darths, having a low level of midiclorians but still able to somewhat using the Force.

In an official flash game before the actual episode, Darthenshmirtz served as the main antagonist, kidnapping the Rebel Animal Agents, imprisoning them in carbonite and scheming his evil plan. In the end of each level Darthenshmirtz appears as a boss in a giant stormtrooper-helmet-ship. Then, he was defeated and forced to retreat.

Phineas and Ferb: Star Wars
Darthenshmirtz first appears, going to the Death Star on a Doofenshmirtz-Evil-Incorporated-like-starship. According to the sith, he claims that he was the one who came up with the idea of creating the Death Star. He also claims that it was originally designed to be a nutcracker, but Darth Vader stole the idea and turned it into a space station. To prove that he's the better Sith than Darth Vader, Darthenshmirtz created the Sith-inator to increase his evilness, and turn his nemesis, Perry the Rebelpus, into a Sith. To do so, Darthenshmirtz and his robot assistant Norm-3PO go around picking up trash or any objects that were personally touched by Vader, since they can pick enough Force for the Sith-inator to power up. Perry is then sent by the Rebellion to stop Darthenshmirtz from completing the -inator, but he ends up being trapped in carbonite. However, as Darthenshmirtz attempt to hit the trapped Perry with the Sith-inator, he accidentally hits Ferb, which resulted in him turning into a Sith.

Darthenshmirtz and Norm-3PO then attempted to get more objects touched by Vader to power up his machine, but by the time he got back, Perry has escaped, disabled Norm-3PO, and engaged into a fight with Darthenshmirtz. While Darthenshmirtz was fighting Perry the Rebelpus, the Sith Ferb ends up engaging into a lightsaber battle with Phineas. During the fight, Darthenshmirtz accidentally ended up getting encased in carbonate. However, Phineas manages to destroy the Sith-inator, resulting Ferb to turn back to normal, allowing them and their friends to escape the Death Star. This also allowed Perry to get into a escape hovercraft, taking the trapping Darthenshmirtz with him so that he can take him into Rebel custody. However, after the Death Star has been destroyed, Darthenshmirtz manages to break out from his carbonite trap and taunts Perry as he escapes in one of the hovercraft's escape pods, much to Perry's anger. However, as he escapes, Darthenshmirtz soon learns that the pod is platypus-sized, making it difficult for him to move around. It is unknown what happened to him afterwards.
