6) New Speedsters
It wouldn’t be The Flash without an evil speedster around to cause trouble for Barry. Following on from Reverse-Flash and Zoom, season 3 will introduce Savitar as – in a fresh move – one of two big bads for the season. He will be played by Todd Lasance.
Barry will also find himself with another speedster on his side, for once – as his adoptive brother Wally will become Kid Flash. We definitely know this will happen in the Flashpoint reality but we are pretty sure this is something that will carry over into the main timeline as well.
We might also be seeing Teddy Sears back as an undead version of Zoom called Black Flash.
