Ralph Dibny’s Elongated Man costume seen in the trailer for this week’s episode of “The Flash” is not the character’s final superhero suit.

Hartley Sawyer told ComicBook.com and other news outlets on the Vancouver set of the CW series that his character will get a new suit later in the season. “It does go through an evolution,” Sawyer said of Ralph’s costume. “He will get a better suit. A different suit. Maybe not better. It’s very, very different.”

While Sawyer revealed that putting the plain-looking costume on is a little bit hard, the 32-year-old actor said that it’s actually fun to wear it. “It does not leave much to the imagination,” he added. “But putting it on is fun and it lends itself to a lot of comedy, a lot of moments there with that.”

In this week’s Season 4, episode 6, Barry (Grant Gustin) starts training Ralph to become a superhero, but Sawyer said that Ralph’s journey to becoming a hero won’t be easy. “The learning curve from zero to hero is a pretty big one,” Sawyer said. “It’s tricky because Ralph was not, you know, a bad guy but has just gone on this path. And so coming back from that has been tricky.”

Executive producer Andrew Kreisberg previously said that telling Ralph’s journey to becoming a hero is exciting because it’s different from the other hero stories that the show has already told before.

“We have an episode coming up where Ralph gets hurt and he didn’t know he could die,” Kreisberg said (via Entertainment Weekly). “So Cisco’s (Carlos Valdes) like, ‘I’m sorry, were you only doing this because you thought you were invincible?’ And he’s like, ‘Yes! Why else would I be doing this?!’ So it’s interesting because it’s different. As opposed to a speedster like Jesse (Violett Beane) and Wally (Keiyan Lonsdale), where they were both going on very similar trajectories to Barry, Ralph’s problems and his hero’s journey have different facets to it, which make it feel fresh.”

“The Flash” Season 4, episode 6, titled “When Harry Met Harry…,” airs tonight at 8 p.m. EST on The CW.
