Cyclops gets a lot of funny lines in the series. Film!Cyke is a real Deadpan Snarker. For example:
Xavier: ...There's more powerful mutants then him. What is Magneto after? Cyclops: Maybe it's his way with people (referring to Logan's uncalled-for insults directed at him). Xavier: You don't like him? Cyclops: (Smiling) How could you tell? Xavier: Well, I am psychic.
This little convo.
Wolverine: You gonna tell me to stay away from your girl? Cyclops: Well if I had to do that she wouldn't be my girl. Wolverine: Then I guess you got nothing to worry about, do you... Cyclops? Cyclops: Must burn you up that a boy like me saved your life. You better be careful, might not be there next time. Oh, and Logan... Stay away from my girl.
And, not just his lines, but also the first time Logan and Cyclops interact it completely demonstrates how they're going to get along. When first introduced, Cyclops offers a friendly handshake which Logan leaves hanging. When Logan shows no interest in Xavier's talk, he begins to leave, but realizes Cyclops is in his way. Instead of asking or walking past him, he grabs him by the colar and tries to threaten him. Without flinching, Cyclops just looks down at Logan's grip, before then looking towards Xavier as if asking for permission to hurt him. It cracks this troper up as its one of Cyclops' few scenes.
Wolverine's skeleton sets off the metal detector and Cyclops is clearly exasperated. Wolverine busts out only one claw to give him the middle finger. Cyclops can't help but laugh, while Jean rolls her eyes.
Cyclops raises his hand to his visor. Wolverine: Hey, it's me. Cyclops: Prove it. Wolverine: You're a dick. Cyclops: [beat] Okay.
Incidentally, one of the few lines that survived the draft written by Joss Whedon.
Magneto has all the X-Men restrained with metal in the head of the Statue of Liberty.
Cyclops: Storm? Fry him. Magneto: Ah, yes. A bolt of lighting into a huge copper conductor. I thought you lived at a school.
Wolverine insisting he doesn't need lessons in auto-safety from Rogue, right before he wrecks his camper and goes flying through the windscreen and lands twenty feet away with what looks like a broken neck.
Spider-Man: I am completely in the wrong movie! I am so sorry!
Wolverine stealing Cyclops' motorcycle. Whilst riding he notices a button near one of the handlebars and out of curiosity pushes it. Said button causes a Turbo Boost that speeds up the bike to near dangerous levels. Wolverine even smiles, clearly having a good time with this.
After Sabretooth's failed attempt to grab Rogue in the first act, he comes back to Magneto's lair empty-handed. This does not unnoticed by Toad, who doesn't even have to look up from his welding:
Toad: Weren't you supposed to come back with someone?
*Sabretooth angrily roars*
Sabretooth again gets the Butt Monkey treatment from his comrades when he fails to keep Senator Kelly from falling into the waterways and out of Magneto's custody. When all Sabretooth holds up is Kelly's tattered sleeve, Magneto snarls and leaves the cell, then without breaking stride or turning around, manipulates the cell bars shut so Sabretooth walks right into them and is imprisoned.
Shortly before that, Magneto snarkily greets Kelly with "How we today, Senator? Feeling advanced, I hope."
During his fight with Jean and Storm, Toad does a feint at Jean, which causes her to instinctively jump back defensively. He then does a silly feint dance to mock the situtation, then snaps right back into a serious offensive stance. Jean tries to freeze in him in mid-air with her powers, but he simply spits goo in her face. When he knocks Storm down an elevator shaft later on, he blows a raspberry in glee.
