Wolverine: (to Kurt, about Kitty) ... and keep an eye on the half-pint here.
Shadowcat: Hey!

Wolverine: [taking over training from Beast] The course has a new objective today.
New mutants: [collective groan]
Wolverine: It's called....Mutant Dodgeball.
New mutants: [collective cheer]
Iceman: Yes! I am so good at this game!
Wolverine: Oh, and extra credit for anyone who takes out the ice cube.
Iceman: What?!
Professor Xavier: Why the change of tactics, Logan?
Wolverine: Sometimes, you gotta let kids just be kids.

Wolverine: Alright, I'll try to sweet talk the kid into not smacking down creeps and thugs who deserve it. But you'll be lucky if I don't end up joining him myself.

Wolverine: Everything you've ever learned about yourselves - your strengths, and your limits...it all comes down to this very moment. We're the world's last, best hope to stop this madman.
(to all the X-Men and the volunteer mutants from the Brotherhood, the Morlocks, and the Acolytes.)

Wolverine: Hey, when I give a demo, I give a demo.
Cyclops: A demo, as in "demolish", or "demonstration"?

Wolverine: I came back 'cause I thought I smelled trouble brewing. [glances at Toad] Of course, it could've just been stink-boy there...
Professor Xavier: I wish it was. Welcome home, old friend. We've missed you.

Wolverine: Maybe it slipped your notice, Chuck, but I'm not exactly the model of restraint.

Wolverine: That's it half-pint, keep the ball away from the elf.

Wolverine: The vents were easily breached; gonna have to fix that. Maybe electrifiers, or poison gas sprayers.
Storm: Wolverine...
Wolverine: Alright, alright...knockout gas, then.
Shadowcat (shudders): Is it just me, or is anybody else, like, seriously freaked by all of this? (everyone stares at her) Oh. Right, it's just me? Great.
Nightcrawler: Relax, Kitty; you'll be fine. (he teleports next to her; she gasps) We're right beside you. (he teleports agains on the opposite side of her) Popcorn? (Shadowcat screams) Oops. Heh heh, sorry. Next time I'll honk before I 'port.
Shadowcat: Whatever. Look, guys, it's getting late. If it's no biggie, I'm gonna, like, drop out. (she phases through the floor)
Nightcrawler: Ah. She's fully not into the fuzzy dude. Not that I blame her.
Jean Grey (putting a hand on Nightcrawler's shoulder): Aw, she just needs some time, Kurt. She'll come around.

Wolverine: When did the porcupine start shooting flaming arrows? Did I miss an upgrade notice or something?

Wolverine: You caged the wrong animal, bub!
Scientist: Stop! This place is going to blow!
Wolverine: Let it! Kitty, leave!
Shadowcat: Not without you! (Nightcrawler teleports next to her and grabs her wrist)
Nightcrawler: No argument this time! (he and Shadowcat both teleport out of the labratory; Sabretooth appears behind Wolverine)
Wolverine: Project Weapon X has been terminated!
Season 2

(about Blob)
Quicksilver: If he slips, we're history! Death by blubberbomb!
Avalanche: Fastest way to the top's a straight line, Pietro.

(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.

(Cyclops and Jean Grey show outright affection for each other.)
Shadowcat: Oh, man. Are they for real?
Nightcrawler: [imitating] "Jean, darling, please accept this croissant as a symbol of my love."
Shadowcat: "Oh, Scott... you have such a way with pastry..."
