Justice Star

In Star Wars Infinities: A New Hope, the Rebellion fails to destroy the Death Star, and is itself defeated, leading to the capture of key figureheads of the Rebellion, including Princess Leia.

Five years pass, and the Empire marks the anniversary of the defeat of the Rebellion with a large celebration that includes the recertification of the Senate, and the renaming of the Death Star as the Justice Star. As a symbol of newly found peace, unity and order for the galaxy, the Justice Star was used to eclipse the sun over the capital planet of Coruscant. This newly cristened Justice Star would serve as a mobile seat of the government of the New Empire, traveling from system to system to show that no one system was greater than another.

The celebration was short-lived, however, as Han Solo, Luke Skywalker and Yoda, along with Chewbacca, C-3PO and R2-D2 arrive in orbit over Coruscant and boldly land on the Justice Star.

Yoda and R2 then proceed to commandeer the Justice Star, and send it crashing into Coruscant, bringing an end to the Emperor's rule with his own superweapon.
