To play Bart Allen, a.k.a.
Impulse, Fisher studied Grant Gustin and Candice Patton’s performances.
[Laughs] That is what makes Bart, Bart.

That is what makes Impulse, Impulse.
You’ve got to have one person that’s unhinged, and that’s Bart."
ENTERTAINMENT WEEKLY: How familiar were you with both the show and the character Bart Allen?

I needed to know what was going on.
I needed to know about this timeline [on the show].
What I found, honestly, is that Impulse is 1,000 percent one of my all-time favorite superheroes.

I think that there’s so much real-life, actual humanity in Bart that we can all relate to.
I think his impulsivity is something people either have in spades or wish they had more of.
Heknowsthat he is so cool!
[Laughs] He knows what he can do is awesome, and he has fun with it.
When you watch Impulse fight, he’s laughing and smiling and cracking jokes.
He’s like, “Watch this real quick!”
and then jumps off the wall and flips in the air and does parkour.
What was the most enlightening thing you watched on the show or read while preparing?
The thing that was most exciting for me, honestly, was seeing the dynamic between Barry and Iris.
What can I take from Candice’s interpretation of Iris?
What mannerisms did you end up borrowing from them and making part of your portrayal?
That it’s a big family.
I think my version of Bart going into this was, “What would Bart do?”
That’s Bart, and I think that is so relatable.
I think that Barry is a little more calculated, whereas Bart specifically is not a calculative person.
He does everything based off of instinct.
That was something my version of Bart specifically set out to do so that he wasn’t like Barry.
Being able to play with that duality as an actor?
I got to have so much fun on set every day.
How did you feel when you put on the Impulse suit for the first time?
I’m anactualsuperhero."
This has got to be one of the coolest thing to do as an actor.
How much preparation did you do?
There’s not a lot of preparation that can go into it.
You kind of just have to learn as you go.
It has to have a different kind of zest to it because that’s what makes Impulse, Impulse.
Other than that, there’s no particular style.
How would you describe Bart and Jessica’s dynamic, especially as superheroes?
Probably likeThe Incredibles, it’s siblings first.
It’s not partners-in-crime first.
It’s unconditional support for sure at the end of the day.
If either of us in trouble, we’re going to throw our bodies in front of them.
Bart is the annoying little brother.
“Why do you exist?”
We get to see a little of that as well, which I’m excited about.
The Flashairs Tuesdays at 8 p.m. ET/PT on the CW.
