MySpace TV has another exclusive video for the NBC superhero drama Heroes.

The clip features the first look at Nichelle Nichols — best known for her role as Uhura in the original Star Trek series — in her new role as Nana, Monica’s grandmother from New Orleans (Monica is the new hero being played by Dana Davis).

No word on if Nana, who makes her debut in episode 3 tomorrow night, will have a super power. Nichols told TV Guide that “Nana is tough and undaunted and — like the blues — she just keeps rising to the occasion.”

Nichols in the second Trek alum to join the NBC hit show, now in its second season. In the first season, George Takei played the father of fan favorite Hiro (Masi Oka).

Also from TV Guide:

The character [Nana], who is in dire financial straits, has moved back into her once-flooded home, where she cares for her two grandchildren. One of them, new hero Monica (The Nine’s Dana Davis), is an avenging angel intent on bringing justice to the corruption-plagued Big Easy. Nana is also a great-aunt to Micah, the junior hero played by series regular Noah Gray-Cabey. “Micah is sent to New Orleans to live with the family,” Nichols says.
