The Flash, Earth-2

CW

On The Flash's Earth, Caitlin Snow (Danielle Panabaker) is a sweet, mild-mannered scientist mourning the death of her husband (again).

On The Flash's Earth-2, she's one half of a badass evil metahuman criminal team with said dead husband, who is alive in this alternate universe. Killer Frost and Deathstorm (guest star Robbie Amell, welcome back! We missed you, Ronnie) make their debut in Tuesday, Feb. 9's episode, Barry and co.'s epic odyssey to Earth-2 (called, appropriately, "Welcome to Earth-2"), but you can see the comic book villains' real-life costumes in these new photos from the episode.

The episode mark's Amell's first return since his character sacrificed himself to save Central City in the season two premiere. We'll see that Ronnie and Caitlin's love story is alive and well on Earth-2. Now that we've seen the couple in their villain costumes, let's see where they land in our ranking of TV's superhero costumes. Click through the gallery below to find out where they end up!

The Flash airs Tuesdays at 8 p.m. on The CW.
