The X23 character was created for this series alone, however, like the character Harley Quinn, who was created for Batman the Animated Series, X23 will become a comic book character.

Craig Kyle was the staff member that created X23.

Berzerker: Man! I hate these training sessions!

Berzerker: This is so lame! I don't get why Wolverine can't just do this in the danger room!
Iceman: (doing an impression of Wolverine) "There's no off switch in the real world, bub!"

Cannonball: Hey! Hey! Give me a hand here, would you?
Iceman: Sam! You’re never going to learn anything if I have to keep rescuing you guys!

Iceman: Uh... Did I win?
Wolverine: You can yourself that as your going through the coarse again... all of you!

Wolverine: Take over for me, would 'ya Hank? (they begin to cheer) But I'LL be WATCHING.

Professor X: Rouge, Rouge, take as much time as you need!
Rouge: I just think that I'm not ready to be around allot of people just yet.
Professor X: I understand. And I hope that this doesn't have anything to do with Logan's training session today...
Rouge: What? No... Was that today?

Professor X: Why does Furry think you have anything to do with the S. H. I. E. L. D break in?
Logan: I don't know. But if he thinks I really did anything, this sure ain't the way he'd be picking me up.

Nick Furry: The intruder had metal claws, and had YOUR DNA.
Logan: What?

Wolverine: Someone's playing games with you Furry.
Nick Furry: That's why your here. To help me find out what going on.
Wolverine: How do you have a sample of my DNA anyway?

Doctor Deborah Risman: Weapon X.
Logan: What did you just call me?

Doctor Deborah Risman: I was a scientist for Hydra, an organization that deals with information...
Nick Furry: Don't sugar coat it! They're spies. And dropping operatives in S. H. I. E. L. D walls is they're favorite pastime.

Doctor Deborah Risman: An operarative, X23, was sent to infiltrate this facility, then went rouge on us.
Logan: So?
Doctor Deborah Risman: Trust me, this is cause for concern.

Logan: Why work for the bad guys?
Doctor Deborah Risman: No boundaries. They gave me the chance to push genetics beyond and conventional science had ever seen.

Doctor Deborah Roman: My job was to create a weapon. The perfect weapon, using information from the project called Weapon X. But I failed, time and time again. 22 times to be precise.

Doctor Deborah Risman: It was you Weapon--- Wolverine. Your healing factor was the key, so we... Acquired your DNA.
Logan: You... Cloned me?
Doctor Deborah Risman: Not entirely... I had to make a few genetic variations.

Beast: Aha! Can't out swing the Beast my friend, I am all over this.

Iceman: Oh yeah! Does Beast know how to spice up a training session or what?

Logan: She's a child! Not a weapon! How do you sleep at night?
Doctor Deborah Risman: I don't.

Berzerker: (to Logan) This is impossible. The Professor, Storm, Bobby, not even you could take us ALL out.

Scott: You have to tell us what's going on!
Logan: It's... complicated!

Logan: Extra credit for anyone who takes out the ice cube.

Professor X: Why the change in tactics Logan?
Logan: Sometimes you just gotta let kids just be kids.

The opening teaser includes clips from "Operation: Rebirth," "Self Possessed," and "Grim Reminder."
