Mystique: Gentlemen, meet your new secret weapon.
Quicksilver: Wanda?!
Scarlet Witch: Pietro?!
[Scarlet Witch goes into a rage and starts using her powers against the Brotherhood.]
Toad: Ex-girlfriend?
Quicksilver: Worse! She's my sister!

Nightcrawler: Aha! You forgot to strap me in! Ten points off!
(to Boom-Boom, after he pretends to fall off the stretcher.)

Nightcrawler: Hey. Welcome back, sailor.
Cyclops (grinning): Uh, thanks... ma'am.
Nightcrawler: Ma'am? What's that suppose to mean? [he looks in the mirror to see a feminine version of him; he gasps] Professor!
Professor Xavier: I'm sorry. I couldn't resist. [he, Jean, and Cyclops laugh and so does Nightcrawler]

Nightcrawler: Well, better do as he says. [Nightcrawler teleports, dropping Kitty's muffin, which cracks the floor tiles]
Shadowcat: [to Cyclops] Muffin?
Season 3

Professor X: That's all right, Kurt. Consider your probation over. (As Kurt celebrates, Xaiver turns toward the new arrivals) Yours, however, is just begining. And you can start by cleaning the X-Jet

Rogue: I'm about to feel really big and stupid, if you know what I mean.
(toward Blob, as she prepares to absorb his power.)

Shadowcat (noticing Kurt holding a mistletoe above her head): Kurt! In your dreams!
Nightcrawler: All in the holiday spirit! (he closes his eyes and puckers his lips)
Shadowcat (standing up and running away): Kurt! Knock it off! (Nightcrawler chases her)
Nightcrawler: Come on, Kitty! Just one little kiss? Pleeaase? [Nightcrawler and Shadowcat run past Professor Xavier and Wolverine]
Professor Xavier: Ah, to be young again.
Wolverine: Yeah... glad that's over.

Shadowcat: ... So? What does it need?
Nightcrawler: Something to wash out the taste.
[about the rubbery muffins Shadowcat made for Home Economics class.]

Shadowcat: Hello? Oh, Lance. Hey, I got it, Bobby! Get off the phone! Sorry. So what's going on? Oh. Yeah right, I can totally see us walking around the mall together. What makes you think I wanna- [Nightcrawler clears his throat; Shadowcats looks, gasps, and sees at a muscular Nightcrawler]
Nightcrawler: Hey, Kitty. How's it going?
Shadowcat: Uh, hey let me think about it. I'll call you back. (she hangs up and laughs) What have you done to yourself? [Nightcrawler walks over to her]
Nightcrawler: I've been working out. Can you tell? [his muscular form disappears back to his regular form] Oh bummer. [he walks out of Shadowcat's room; Shadowcat laughs]
Shadowcat: You shouldn't be messing with your image inducer, Kurt.

Shadowcat: How much do you know about the Redwoods?
Iceman: Only that they make great hot tubs.

Shadowcat: Ok, how do these taste after my last six batches?

Toad: Man, this bums, yo. Even the flies here think they're better than us.
Blob: Yeah. I don't even know what we're doing at school anyway.
Quicksilver: But we do know why Lance is here. He'd like to get a certain Kitty stuck in a tree. K-I-S-S-I....
[Quicksilver speeds away as Lance tries to hit him, causing him to hit Toad instead]

(About the New Mutants)
Wolverine: So those are the new recruits? Looks like we got our hands full.
Professor: Yes, a spirited bunch, but good kids. However, it's going to be difficult to keep things quiet, and to maintain our anonymity.
Wolverine: Not to mention our buildings. We're definately going to need more instructors. And maybe a couple of tanks.
[The Brotherhood are standing off to the side at a school assembly]

(Boom-Boom carelessly sweeps Nightcrawler into the stretcher with her foot.)
Nightcrawler: Ow! I'm an injured victim, not a log!
Boom-Boom: "Nightcrawler", huh? That name's just not working for you, I'm sorry. Whoa! How about, "Wild Blue Yonder Boy"?
Nightcrawler: You are insane.

[About letting Avalanche join the X-Men.]
Cyclops: Professor, I think this is a mistake. I know Lance; he wouldn't do this unless he wanted something.
Professor X: Yes, I agree. What he wants, is to be near Kitty.
Cyclops: But-
Professor X: I believe he's genuine about his feelings for her. And maybe, that's a good beginning. Now, let's give him a chance.
Professor X: Well, fortunaly,there's no official mention of the incident. The military must believe it was a UFO sighting, so they are, no doubt, covering it up.
Nightcrawler: Now all I've got to do is wax the X-Jet and my probation is history (eyes the X-Jet). Ohhh man!
This is gonna take alot of wax!
