Wars lacked a cough until the concluding episode, in which Mace Windu Force-crushes the chestplate housing Grievous's internal organs; this was intended to create continuity with the film and was mentioned in its novelization. Conversely, the CGI The Clone Wars series (2008–2014, 2020) depicts Grievous as already being in this weakened state. Volume Two shares aspects of its storyline with the novel Labyrinth of Evil, which was created at the same time. Both the cartoon and book climax with the Jedi chasing Grievous on Coruscant to save Palpatine. The book features a different final duel between Windu and Grievous, but in both titles Shaak Ti acts as Palpatine's primary guardian. In the series, Anakin and Obi-Wan investigate a possible base for Grievous on Nelvaan before being called back to Coruscant. The novel depicts the Jedi duo pursuing Count Dooku on Tythe; while fleeing to Coruscant, Dooku stops at Nelvaan to leave a false trail. While the final season of The Clone Wars references Shaak Ti being sent to guard Palpatine, it depicts Anakin and Obi-Wan in yet a different location just prior to Revenge of the Sith.

Production Lucasfilm reportedly conceived of the series as a way to sell more action figures because the prequel trilogy figures were underselling. It was produced and directed by Genndy Tartakovsky, the creator of Dexter's Laboratory and Samurai Jack, and employs a similar animation style to the latter. According to Tartakovsky, the series was developed in two weeks and created by a small crew and "it was stressful because I had to translate this world I've loved since I was a kid into something completely different." Tartakovsky stated that he deliberately animated with moveable expressive eyes to pay homage to his animated appearances in the Star Wars Holiday Special and Droids. Additionally, the planet Nelvaan's name was a nod to Nelvana, the production company that produced all previous Star Wars animated series. In "Chapter
