Streeen

Streeen and Luuuke created a time machine after the Lost Tribe of the Sith emergence. The pair used this to transport the Army they gathered together to the galaxy during the Clone Wars period, when they fought Anakin Skywalker, Obi-Wan Kenobi and the Grand Army of the Republic.

Behind the scenes
Streen was mentioned in An Apology, a short story by Timothy Zahn that was released on April 1, 2012 as an April Fool's Day joke. In the context of the story, any appearance of Luke Skywalker following the Fate of the Jedi series would be Luuuke. Further, the article in which An Apology was published announced facetiously that Luuuke would star in upcoming novels such as Star Wars: The Clone Wars 2: Luuuke. The novel serial, The Clone Wars 2 or Son of Clone Wars, was to continue releasing titles for perpetuity, and Luuuke's adventure with Streeen would have taken place in the seventeenth volume of the tale.
