2. Quinlan Vos
Quinlan Vos is one of the most prominent untapped characters from The Clone Wars, with so many unanswered questions about him that he is simply begging for some screentime. The novel Dark Disciple by Christie Golden covers the final months of the Clone Wars for Quinlan when he was both the love interest of Asajj Ventress and a Sith apprentice to Count Dooku. This book was crafted from scrapped scripts from The Clone Wars after Cartoon Network canceled it. During this time, Quinlan was tasked with assassinating Count Dooku. He sought out Ventress to aid him, and the two fell in love. But Quinlan slipped into the Dark Side and became Admiral Enigma, fighting against the Republic and Jedi he swore to protect. Eventually, Quinlan came back to the light side and rejoined the Jedi.
Dark Disciple also brought an end to Ventress’ story. While Quinlan would be the focus of Tales of the Jedi, it would also give a chance for the return of Ventress to help offer some on-screen closure to a fan-favorite character. Besides, Tales is no stranger to running over other novels. Why not Dark Disciple?
We also know that Quinlan survived Order 66 thanks to Charles Soule's run of Darth Vader comics as well as the Obi-Wan Kenobi series. The latter revealed that Quinlan was working with the Path helping to smuggle Force-sensitive children to safety, something that gave Kenobi the hope he was looking for to fight back. It could be a great chance to bring back Indira Varma, O’Shea Jackson Jr., and Kumail Nanjiani as Tala, Roken, and Haja too.
Quinlan is such a huge question mark in the Imperial period, with stories primed and ready to be on screen. This man could hold an entire season all on his own.
