"When I was eleven, my mom was murdered. It look like a ball of lightning. Inside the lightning...was a man."
Flash series seems to incorporate a little bit of the "New 52" mythos with us learning that Barry's mother was murdered (in the comics, seemingly done by his father) but here, it has the all too familiar shades of Eobard Thawne, aka Professor Zoom. Could Thawne and Barry be connected here? Is the ball of lightning the Speed Force itself or something more?
Beyond that, this trailer shows an origin for Barry’s powers that’s nearly identical to his classic, Silver Age origin, right down to some subtle, visual cues. Of course, the incorporation of S.T.A.R. Labs, and the possible cause of his ascent to metahuman are new, but it's a solid mix of old and new that still gives fans an air of mystery.
