SDCC: 'The Flash' Season 3 Trailer Previews Kid Flash, Reverse Flash, and Ramon Industries?

Fans were given a look at the upcoming season of the CW's 'The Flash' with the first trailer on Saturday at the San Diego Comic-Con. Season 3 presents the "Flashpoint" timeline where everything changes after Barry (Grant Gustin) goes back in time again to save his mother. 

Barry thinks he has it all figured out, finally enjoying his family intact but all his other relationships have changed dramatically. Joe (Jesse L. Martin), Iris (Candice Patton), Cisco (Carlos Valdes) and Caitlin (Danielle Panabaker) are nothing like they were in the previous timeline. Oh, and Wally West (Keiynan Lonsdale) is now Kid Flash. Luckily, Barry is still The Flash but he's created a whole new set of problems as explained to him by Reverse Flash himself, Eobard Thawne (Matt Letscher) in the trailer. Dr. Alchemy is one of the big bad guys along with a mysterious dark speedster for the upcoming season.

The Flash returns on Oct. 4 to the CW.
