Hero, Natasha Romanoff from Avengers (2012)

Clint Barton: [Natasha has freed him from his restraints] Tasha, how many agents did I-?
Natasha Romanoff: Don't. Don't do that to yourself, Clint. This is Loki. This is monsters and magic and nothing we were ever trained for.
Clint Barton: Loki, he got away?
Natasha Romanoff: Yeah. Don't suppose you know where?
Clint Barton: [Shakes head] Didn't need to know. Didn't ask. He's gonna make his play soon though. Today.
Natasha Romanoff: We gotta stop him.
Clint Barton: Yeah, who's "we"?
Natasha Romanoff: [Shrugs] I don't know. Whoever's left.
Clint Barton: Well, I... if I put an arrow through Loki's eye socket, I'd sleep better, I s'pose.
Natasha Romanoff: Now you sound like you.
Clint Barton: But you don't. You're a spy, not a soldier. Now you want to wade into a war. Why? What did Loki do to you?
Natasha Romanoff: He didn't, I just...
[pauses]
Clint Barton: Natasha.
Natasha Romanoff: I've been compromised. I got red in my ledger. I'd like to wipe it out.

Superhero, Halle Berry as Catwoman from Catwoman (2004)

[voiceover] The day I died was the day I started to live. In my old life, I longed for someone to see what was special in me. You did, and for that, you'll always be in my heart. But what I really needed was for me to see it. And now I do. You're a good man, Tom. But you live in a world that has no place for someone like me. You see, sometimes I'm good. Oh, I'm very good. But sometimes I'm bad. But only as bad as I wanna be. Freedom is power. To live a life untamed and unafraid is the gift that I've been given, and so my journey begins.

Hero, Halle Berry as Catwoman from Catwoman (2004)

[voiceover] It all started on the day that I died. If there had been an obituary, it would have described the unremarkable life of an unremarkable woman, survived by no one. But there was no obituary, because the day that I died was also the day I started to live. But that comes later. This was my life. Days blended together, consistently ordinary, thanks to a job that was the practical version of my passion. I was supposed to be an artist by now. Instead, I was designing ads for beauty cream.
