NBC has released the :30 teaser for its new DC Comics series Powerless, which debuts February 2.  The cast, led by Vanessa Hudgens, remains the same, but the concept has evolved.  Now Hudgens works for Wayne Security, which makes products that protect people from superhero-caused mayhem.  The show was originally written around an insurance company that insured against superhero damage (see "NBC Gets Its Own DC Series").
