There’s little standing in the way of The Flash’s 2016 return with Tuesday’s “Potential Energy,” but the future has plenty more obstacles to throw at the team. Catch a better look at Killer Frost and Deathstorm in action, along with new looks at Wally West and the Reverse Flash’s return in a new universe-ending trailer!

The newest trailer for the back half of Season 2 gives us a better look at the group’s upcoming trip to Earth-2, including everyone’s respective counterparts. We also now know that the Reverse Flash we meet will be from an earlier timeline, before the figure took over the real Harrison Wells’ body, and ended up erased from existence.

In the meantime, so reads the synopsis for 2016 premiere “Potential Energy”

JOE AND IRIS GET TO KNOW WALLY — Now that they’ve grown closer, Barry (Grant Gustin) considers telling Patty (guest star Shantel VanSanten) that he is The Flash. Meanwhile, Joe (Jesse L. Martin) and Iris (Candice Patton) try to get to know Wally (Keiynan Lonsdale), and the team hunts down a meta-human who can slow time itself.

There’s plenty to see of The Flash and Earth-2 between now and then, but check out the latest photos and trailers below.
