New Flash Trailer Teases Mark Hamill's Trickster, Captain Cold's Sis and More

Beware the villains of March, Flash fans.

A new sizzle reel for the freshman CW hit’s next three episodes reveals not one or two but three new baddies, starting with the legit Weather Wizard (played by Spartacus‘ Liam McIntyre) on Tuesday, March 17.

What’s more, the last five minutes of that episode, the promo promises, will “change the course of history” — seemingly due to some time travel.

The following Tuesday brings back Captain Cold (Wentworth Miller) and Heat Wave (Dominic Purcell), now accompanied by Snart’s sister Lisa (The Tomorrow People‘s Peyton List), who in DC Comics lore is a supervillainess dubbed Golden Glider.

Then on March 31, Star Wars icon Mark Hamill reprises his role as James Jesse aka The Trickster from a 1991 episode of TV’s original The Flash — giving Cisco more material (including of the Spandex variety) than he knows what to do with.

Watch the trailer above and name the guest star(s) you most anticipate.
