The Star Wars universe is constantly expanding, with brand-new spinoffs, prequels and sequels appearing every few months on Disney+. The new series Andor is just the latest of the Star Wars projects on the horizon that will keep viewers busy for years to come.
While the Star Wars spinoffs have certainly been plentiful, they have also been primarily focused on the heroes of the franchise. However, there are many malevolent characters therein, Sith, Imperial, or otherwise, who could very easily carry their own spinoff in a compelling fashion.
Grand Admiral Thrawn
Grand Admiral Thrawn is one of the most chilling villains in the Star Wars universe, whose strategic mind and ruthless nature would have made him a terrific Sith if he'd had Force powers. The Imperial commander appears in the animated series Star Wars: Rebels and is expected to return in the forthcoming Disney+ series Ahsoka.
Thrawn is by far one of the most complex villains in the franchise, with plenty of backstory that expands beyond even the boundaries of the known Star Wars galaxy. As such a dynamic character, the Chiss strategist certainly deserves his own spinoff, perhaps one explaining his rise to power amidst the Imperial navy.
Kylo Ren
Adam Driver portrays Ben Solo, a.k.a. Kylo Ren, in the Star Wars sequel trilogy. When the audience first meets him, he has already succumbed to the dark side, but he soon undergoes a redemption arc that culminates in The Rise of Skywalker, when he ends up with a heroic death after all.
There are still plenty of gaps in Kylo Ren's fall and betrayal of Luke Skywalker. A miniseries exploring this dark turn could go a long way in filling in the holes left by the sequel trilogy's story, while also painting Ben Solo as a more sympathetic character, much in the same way that Anakin Skywalker was portrayed as sympathetic in the prequel films.
Grand Moff Tarkin
Grand Moff Tarkin is one of the more memorable non-Sith villains in the Star Wars franchise, who serves as the main commander over the first Death Star in A New Hope. He meets his end when the space station is destroyed by Luke Skywalker during the Battle of Yavin, limiting Tarkin's contributions to the series.
Very little is known about Tarkin from the films and series alone, making him the perfect character to expand in a solo project. His days in the Republic army would be quite interesting to watch as he begins to associate himself more and more with the man who would become the Emperor, becoming one of his most trusted soldiers.
Supreme Leader Snoke
Andy Serkis portrays the mastermind behind the First Order, Supreme Leader Snoke, in the sequel trilogy. Snoke is the one who turned Kylo Ren to the Dark Side and plans to do the same to Rey, though he is unceremoniously killed by his apprentice during the events of The Last Jedi, ending his evil plans.
Snoke was a disappointment to many fans, mostly due to his early death and minimal impact to the sequel trilogy's plot. However, the character could prove to be quite interesting if given more screen time, especially given Andy Serkis' winning performance using motion capture technology.
Darth Plagueis
Darth Plagueis is perhaps the most famous Star Wars villain never seen onscreen. Memorably mentioned by Sheev Palpatine in Revenge of the Sith, Plageuis was a powerful Sith Lord who had the power to manipulate the Force into keeping certain people from dying. He is killed in his sleep by his apprentice, who is revealed to be Palpatine himself.
The tragedy of Darth Plageuis the Wise would prove very interesting to see play out on screen, filling in the gaps left by Palpatine's one-sided telling of the story. Many fans have been fascinated with the Sith Lord for years, longing to see his live-action debut and the culmination of his legendary story.
General Grievous
General Grievous is the commander of the Separatist droid army during the Clone Wars. An avid collector of the lightsabers from the Jedi he'd murdered, Grievous acts as a pain in the Republic's side throughout the war until he is eventually killed by Obi-Wan Kenobi during the events of Revenge of the Sith.
Very little character work has ever been done with General Grievous since his introduction, but his backstory as a warrior longing to perfect his skill could prove to be riveting if put to screen. The once-organic cyborg truly has plenty of stories to be told, delving into his past to uncover the truth about his character.
Count Dooku
Count Dooku is a fallen Jedi Master and the one-time master of Qui-Gon Jinn. The character will soon appear in the animated spinoff Tales of the Jedi, where more of his backstory will be explained, expanding on what little is seen of the character prior to his gruesome death at the hands of Anakin Skywalker in Revenge of the Sith.
Count Dooku is one of the most complex villains in the Star Wars franchise, though he is often ignored by various films and series. The former Jedi has countless connections to the films' main characters, and certainly has an interesting story to be told regarding his fall from the Light Side and subsequent tutelage under the supervision of Darth Sidious.
Darth Vader
Darth Vader is one of the most famous villains in the history of cinema, whose story as Anakin Skywalker comprises much of what is referred to as the Skywalker Saga. A fallen Jedi whose powers were stunted by a grave injury, Vader eventually dies after returning to the Light Side during the events of Return of the Jedi.
While much of Anakin Skywalker's story has been told, viewers have still seen precious little of Vader's days post-Order 66. The character's exploits during this time are legendary and what little fans have seen thereof, in projects like Obi-Wan Kenobi and Rogue One, has become iconic. Putting such endeavors to screen would no doubt excite fans to no end.
Emperor Palpatine
Emperor Sheev Palpatine is undoubtedly the ultimate villain of the Star Wars franchise, serving as the "Big Bad" of all three trilogies in the Skywalker Saga. Cheating death on numerous occasions, Palpatine meets his final end in The Rise of Skywalker when he is defeated by his granddaughter, Rey, who channels the power of the Jedi to kill him.
Palpatine's schemes and conniving strategy have made him one of the most impressive villains in the franchise, though very little has ever been seen of the character prior to his days in the Republic. Fans need to see his early training in the Dark Side in order to properly understand his reign of terror as the galaxy's emperor.
Darth Maul
Darth Maul makes his first appearance in The Phantom Menace, where he appears to be killed by Obi-Wan Kenobi. The Sith apprentice would appear for many years thereafter, however, most notably in the animated series The Clone Wars, where his character was expanded, becoming a favorite among fans of the series.
Though he was originally little more than a placeholder villain, Darth Maul has become incredibly complex over the years, making him a fan-favorite character. Fans simply can't get enough of the Sith apprentice, making a spinoff project following the character near the top of every fan's list of desired spinoffs. While much of his story between The Phantom Menace and his death during Star Wars: Rebels has been filled, there are still several years in which his exploits remain a mystery, making prime material for a spinoff series, perhaps even resolving the loose ends from the finale of Solo.
