Disney movies, whether of the Disney Animated Canon variety or Pixar variety, often tend to have very noticeable snarkers. Here are some examples, in chronological order.
Bagheera from The Jungle Book, such as when talking to Baloo about whether or not to take Mowgli back to human society:
Baloo: Oh, stop worrying, Baggy! Stop worrying! I'll take care of him. Bagheera: Yes, like you did when the monkeys kidnapped him, huh?
Beast: You come out or I'll... I'll... I'll break down the door! Lumiere: Master, I could be wrong, but that may not be the best way to win the girl's affection.
The Beast himself has his moments.
Lumiere: Voila! You look so...so... Beast: ... Stupid.
Jafar: Patience, Iago, patience. Gazeem was obviously less than worthy. Iago: Oh there's a big surprise! I think I'm going to have a heart attack and die from that surprise!
Scar, Timon, and Nala from The Lion King, but especially Scar.
Simba: I'm going to be king of Pride Rock! Scar:Oh, goody. Simba: My dad just showed me the whole kingdom, and I'm going to rule it all! Scar: Yes, well forgive me for not leaping for joy. Bad back, you know.
Atta: You sure it's not up there? Hopper: ... are you saying I'm stupid? Do I look stupid to you? Let's just think about the logic, shall we? Let's just think about it for a second. If it was up there, would I be coming down here to your level, LOOKING FOR IT?
Pacha: Why did I risk my life for a selfish brat like you? I was always taught that there was some good in everyone, but, oh, you proved me wrong. Kuzco: Oh, boo-hoo. Now I feel really bad. Bad llama. Pacha: I could've let you die out there in that jungle, and then all my problems would be over. Kuzco:Well, that makes you ugly AND stupid.
Bolt: I will super-bark you out of that tree! Mittens: Go nuts. Let's see how that works out for ya. Bolt: You leave me no choice. *Bark!* Mittens:Oh, the super-bark. Scary, scary.
Charlie Barkin from All Dogs Go to Heaven fits this trope perfectly, not only in his words, but in his facial expressions and actions as well. To get the full effects of Charlie's Deadpan Snarkerness, you have to watch this scene, where Charlie "tucks" Anne Marie into bed in his cab:
Anne Marie: Charlie, your front seat *hurts* me!
Charlie: Oh yeah? All right...all right. All right. [beat] Dames...
Hiccup in How to Train Your Dragon intermittently comes out with some of the most hilariously matter-of-fact lines ever.
"And now the spinning. Thank you for nothing, you useless reptile." "You just gestured to all of me!" "Thank you for summing that up." "Dat-da-da, we're dead."
Kate the alpha wolf in Alpha and Omega shows this off during serious situations.
Francis from Felidae can show to be a deadpan snarker at times.
Bluebeard: Why did you run off? The brothers just wanted to talk. Francis: I bet they would with 300 volts loosening my tongue!
