Rooster Teeth's new series, gen:Lock, won't premiere until January 2019, but a new teaser was released at RTX Austin, providing us with a fresh look at the highly anticipated show.
The minute-and-a-half preview isn't too revealing, but it does briefly show Julian Chase (Michael B. Jordan) in action while piloting a mecha. Also, it introduces the character Yasamin Madrani, who will be joining Chase in the pilot program.
However, the character at the forefront of the new teaser is David Tennant's Doctor Rufus Weller. We never actually see the doctor, but we do hear him engage in some fun banter with Colonel Marin as he negotiates to have Madrani transferred into his custody.
