The concept of a ring-shaped space station that encircles an entire planet was first developed for Star Wars during the concept design phase of Star Wars: Episode III Revenge of the Sith.

Clone Commander Doom's colors closely resemble that of classic Marvel Comics villain Doctor Doom.

Tiplee and Tiplar are based on concept design for a female Sith Lord that Iain McCaig developed for Episode II that ultimately was not used.

Admiral Trench was last seen in "Cat and Mouse," an episode from the second season of Star Wars: The Clone Wars that, chronologically, is the first story to occur in the series.

Though it is described in dialog and in the script as a medical frigate, the vessel at the end designated 517 uses the standard Republic frigate animation model.

This episode debuts a new, updated design for the super battle droid rocket trooper. A more basic repaint of the standard droid was seen in the Season One episode, "Jedi Crash." This new design features custom rocket pods built into exaggerated shoulders, in a look that faintly echoes the female Zentraedi power armor from the Robotech animated series.
