Fans of The Flash will get their first look at Ronnie Raymond (Robbie Amell) in tomorrow night's episode "Things You Can't Outrun". The character is one half of Firestorm, with Dr. Martin Stein (Victor Garber) portraying the other half. Before fans are introduced to Ronnie, Robbie Amell offers the first details about his character in an interview with The Hollywood Reporter.

Firestorm isn't as big a name in the DC comic book universe. Amell reveals that he wasn't too familiar with the character before he landed the role.

"I knew of him and I knew a little, but I hadn't been a huge Firestorm fan. But I'm actually kind of glad that it happened that way because I got to be introduced to a new superhero. I got a care package from DC with a couple comics and a couple action figures. My mom went out to a comic book store and bought out every Firestorm piece of merchandise they had, and I dove head-first into the universe. I think I'm going to do something that Firestorm fans will like."

The character was engaged to Danielle Panabaker's Caitlin Snow before he was believed to be killed during the particle accelerator explosion. Ronnie Raymond first appears in a flashback to the night of the accident, with Robbie Amell revealing that he hadn't seen the pilot yet when he shot his first episode.

"I hadn't seen the pilot [when I filmed that episode], but I'm glad I hadn't since the flashbacks happen at the same time as the pilot. I got to walk into it as completely blank slate. We shot the celebratory scene first, which was great; it's always exciting coming into a new project. It actually had a lot of the same crew, about 70 percent, with The Tomorrow People moved over [to The Flash]. Trying to establish a relationship with Danielle's character Caitlin in a short period of time ended up going well because we had mutual friends and we sat down and talked for a while before we shot anything. I've only seen a couple clips; I'm excited to watch the episode tomorrow night. I've become a big fan of the show."

While fans will get their first look at Ronnie tomorrow, the character will return in December, where we will see the fully-formed Firestorm for the first time.

"You meet Ronnie Raymond tomorrow and then in December, you meet Firestorm. It'll take a minute before Firestorm turns back into Ronnie because when they find him in December, my character is really going through some stuff. He's schizophrenic, doesn't know what's happening, he's confused and dangerous to the people around him. You may not see Ronnie Raymond for a little while, but you'll see Firestorm."

He added that viewers will not be able to recognize Ronnie from Firestorm when he debuts in December.

"It's a huge difference. People will barely recognize him in December, but they'll know it's him when the fire bursts in the hands and the fire bursts in the head. The particle accelerator almost killed Ronnie and the fallout from it will definitely be seen in December."

The actor also addressed how his relationship becomes strained between Ronnie and Caitlin once she realizes he isn't dead.

"The relationship between the two of them is definitely [a question]. It's tough because when Firestorm comes back, it should be this great reunion but Firestorm is so far removed from Ronnie Raymond that it's not quite the reunion people will be hoping for."

When asked about working with Victor Garber, Robbie Amell had this to say.

"It's the best! It's so awesome! I worked with Victor Garber on a TV movie a couple years ago and he was awesome. He's so freakin' talented and it doesn't hurt that my fiancee [actress Italia Ricci] is the biggest Titanic fan I've ever met. She's more excited about me working with Victor Garber than anything else. I gotta start watching Alias and start working on my Victor Garber impression. Sometimes Firestorm is Ronnie and sometimes he's Martin Stein, but physically it's going to be my body. I'm just excited to work opposite him because, I mean, he's Victor Garber. The fact that I get to share a character with this guy is going to be really fun."

When he starred in The CW's The Tomorrow People, Robbie Amell's character Stephen Jameson had telekinetic powers. When asked if his powers on The Flash will be similar, the actor had this to say.

"Yeah. The telekinesis [on Tomorrow People] is really similar to my shooting nuclear energy out of my hands and some other powers, which I can't give away. One of them is really badass and that'll be revealed in one of my episodes in December. They're not holding anything back. Firestorm is very powerful and it definitely helps to have been shooting a sci-fi show leading into this."

When asked if he will be one of The Flash's most dangerous enemies, the actor had this to say.

"From the amount of powers they've given him, he's going to be a difficult foe for anyone to go up against."
