Who is Wally West? Comic book fans will know Wally as the nephew of Iris West (Candice Patton). In the comics, Wally is a Flash super-fan and comes to visit his aunt in Central City. Then, a lightning strike results in him gaining the same powers as Barry and becoming Kid Flash!

Wally will not be the only new face next season. It was previously reported that “The Flash” was seeking an actress to play the role of Patty Spivot. Comic book readers know Patty as the forensic scientist, specializing in blood, who ends up falling for Barry while working with him at the Central City Police Department. However, in the CW series the character will join the team as Joe’s new partner, replacing Eddie. Patty will become the first major female cop character on the show. Shantel VanSanten (“One Tree Hill”) will play Patty.

S.T.A.R. Labs is getting crowded. How will Barry, Iris and co. handle all of the new characters? Fans will have to wait to find out. Season 2 of "The Flash" will premiere on Oct. 6 on the CW.
