In the TV show Star Wars: Tales of the Underworld (2025), one character's death is specifically referenced: Asajj Ventress. However, her death is not a final event but rather a part of her story. She was initially believed to be dead following events depicted in the novel Dark Disciple, which adapted an unfinished arc from Star Wars: The Clone Wars.

In Tales of the Underworld, it is revealed that after being laid to rest by Quinlan Vos and Obi-Wan Kenobi, Ventress' spirit is offered resurrection by the spirit of Mother Talzin, a powerful figure from Dathomir. Ventress accepts this offer, allowing her to return to life.

This show explores the theme of mortality in the Star Wars universe, where death is not always permanent, as seen with other characters like Darth Maul and Emperor Palpatine. However, specific details about new characters dying within the series are not provided in the search results.
