The CW's hit DC Comics drama "The Flash" has already teased some interdimensional travel for its second season, but in a new promo clip, the series is hinting at some powerful changes for Barry Allen as well.

Australia's Fox 8 -- where the series premiers in that country as "DC's The Flash" -- just posted a new teaser for Season 2 of the show on its Facebook page. The clip highlights the hypersonic hero running with some blue electrical discharge following behind him -- a small tweak to the Flash's power set that may serve as a portent for things to come in the show.

The series has already promised a new costume for star Grant Gustin, and among the long list of new guest stars arriving in the second season will be Teddy Sears as Earth-w speedster Jay Garrick.

"The Flash" returns to The CW on October 6.
