An exclusive First Look at his appearance on the March 31 episode reveals that one of DC Comics’ most notorious villains has been in prison for 20 years – and has had “20 years to come up with the perfect trick.”

The promo – which teases the next three episodes starting March 17 – also gives us a sneak peek at a few other Flash villains, both new and returning.

Weather Wizard (Liam McIntyre) begins terrorizing Central City in “Out of Time”; in “Rogue Time,” airing March 24, Captain Cold (Wentworth Miller) returns with little sister Lisa Snart (a.k.a. Golden Glider, played by Peyton List) in tow.

However, with all these meta-humans invading Central City, there’s just one that Barry (Gustin) has his sights set on – his mother’s killer.
