The new Rogue One: A Star Wars trailer revealed a glimpse of Darth Vader, but Lucasfilm and Disney haven't released it online yet.

The new trailer begins with Jyn as a little girl running. "There's not much time. Every day, we grow weaker, while they grow stronger. This is our chance to make a real difference." The trailer featues a lot of battle sequences, new aliens, new shuttle craft, an X-Wing flying over a forest-heavy planet, Deathtroopers, and the Death Star, then it ends with Darth Vader standing and breathing over a display. Then see a reflection of Vader appears on the panel.

This is the second leaked clip of the same trailer. Check it out:

Rogue One stars Felicity Jones, Diego Luna, Ben Mendelsohn, Donnie Yen, Jiang Wen, Forest Whitaker, Alan Tudyk, and Riz Ahmed, and it's directed by Gareth Edwards.

Rogue One: A Star Wars Story will hit theaters on December 16, 2016.
