* ''WesternAnimation/TheSmurfs'': Grouchy Smurf. About 90% of his dialog consisted of the phrase, "I HATE (insert thing here)!" (except in the movie, where's he's more vocal and sarcastic).
** He becomes less of this by the end of ''[[WesternAnimation/TheSmurfsAChristmasCarol The Smurfs: A Christmas Carol]]''.
* Gruffi of the ''GummiBears''. Partially subverted in that while his irascible nature is irritating, he is also respected for his practical nature which is invaluable in times of crisis.
* Zuko from ''WesternAnimation/AvatarTheLastAirbender''. "I'm [[EmoTeen never happy]]." And his [[BirdsOfAFeather girlfriend]] Mai.
* Some of the human ''WesternAnimation/LooneyTunes'' characters can be grouchy. For example: Yosemite Sam, Elmer Fudd, and some other minor characters like Casper Caveman.
* Ratchet from ''WesternAnimation/TransformersAnimated'' is justified in that he is a war hero who has seen enough to have lost his innocence about things and has become gruff to a fault. Even Captain Fanzone, the by-the-book police officer, has told Ratchet to work on his people skills.. HilarityEnsues when Ratchet's attempts to bring a pregnant woman to the hospital in his ambulance mode ''make her leave and take a cab''. His cynicism is often contrasted with Optimus Prime's idealism and patriotism.
** When you've been mutilated by a part-stealing bounty hunter, seen the soldier you were supposed to protect mindwiped in front of you [[spoiler:(hell, been the one to mindwipe her!)]], and [[spoiler:the lobotomized body of your old war buddy is turned into a transport for some washout Elite Guard cadet]], cranky makes sense.
* Pierre of [[ShowWithinAShow the Squishy Bears]] from ''WesternAnimation/EekTheCat''.
* Beast Boy's ex-teammates the ''Comicbook/DoomPatrol'' show up in the last season of ''WesternAnimation/TeenTitans'', and start reminding BB that sometimes you have to ShootTheDog to save the world. Then the kids after whom the show is actually named show them that all the {{Heroic Sacrifice}}s they only ''thought'' were necessary can just be undone off-screen anyway.
* Benson from ''WesternAnimation/RegularShow'', especially when threatening to fire Mordecai, Rigby, or both.
** To be fair, he has this behavior based on dealing with the two of them. He sometimes acts like this towards Muscle Man when he's being obnoxious, but he's actually fairly nice towards Pops, Skips and Thomas.
* ''The Happy Little Elves'', a ShowWithinAShow on ''WesternAnimation/TheSimpsons'', had "Chilly, the elf who cannot love".
* Mr. Grumpy on ''WesternAnimation/TheMrMenShow''.
* Twilight Sparkle from ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' started out as a rare case of the Grumpy Bear being the main character, as well as the [[OnlySaneMan Only Sane Pony]].
* Gusty from ''WesternAnimation/MyLittlePonyAndFriends'' is this, as well.
* In ''WesternAnimation/KaBlam'', [[DeadpanSnarker June]] sometimes falls under this.
* Mr. Mufflin in ''WesternAnimation/FanboyAndChumChum'' [[spoiler:when he's at his worst]].
* Bob (only annoyed) in ''WesternAnimation/BobsBurgers''.
* Dan from ''WesternAnimation/DanVs'' fills the trope when things wrong him in the opening.
* Huffer from ''TransformersGeneration1'' was ''built'' for this role almost literally; fellow [[IncrediblyLamePun crank-case]] Gears might count as either this or a SourSupporter, if A] he wasn't faking it for the sake of morale and B] he ever actually said anything in the cartoon.
* Ed Bighead from ''WesternAnimation/RockosModernLife''.
* Spinelli from ''WesternAnimation/{{Recess}}''.
* The Angry Cop from ''WesternAnimation/TheGoodeFamily'' episode "[[ParodyEpisode Gerold's Way or the Highway]]".
* Grumbly Green from ''WesternAnimation/TheBlobs'':
-->I don't like where I'm going,\\
I don't like where I've been.\\
I'm grumbly, groany, leave-me-aloney,\\
Mumbly, Grumbly Green.
* Stu Pickles from ''WesternAnimation/{{Rugrats}}'' can be like this sometimes. Like Homer Simpson and his dad above, Stu also has a father who can be grumpy, Lou Pickles. Not only that, but Drew Pickles seems to be grumpy, too, especially when Stu and Drew had an argument most of the time.
* WesternAnimation/DonaldDuck is a Grumpy Disney Duck. He can be ''very'' temperamental.
* [[KariWahlgren Morgan]] from ''WesternAnimation/RandyCunninghamNinthGradeNinja'' combines this with the AlphaBitch and SurroundedByIdiots tropes.
* Squidward from ''WesternAnimation/{{SpongeBob SquarePants}}'', mostly because of his annoying neighbors.
* ''Franchise/CareBears'': Grumpy Bear might say, "Of course you got all the way to the bottom of the Western Animation section before anyone thought of me, even though [[TropeNamer my name's on the page]]." He's the most practical of the bears, and the local Mr. Fix-it (which, according to Share Bear in the 1985 movie, is because he never complains). He tends to have the role of ButtMonkey. Being so grumpy perhaps makes the writers feel less guilty about giving him so much trouble. In fact, the whole reson he was created was to teach children that it's ok to be grumpy sometimes (but it's silly to let grumpiness go too far).
* Gordon the Big Engine from ''WesternAnimation/ThomasTheTankEngine.'' His arrogance seems to stem from his inability to tolerate everything around him. James even [[LampshadeHanging lampshades]] his grumpiness in the Season 5 episode ''A Better View For Gordon.''
* Buttercup from ''ThePowerpuffGirls''.
* Anton St. Germain & Penny from ''WesternAnimation/TheMightyB'' are also annoyed by Bessie Antics.
* Principal Pixiefrog from ''WesternAnimation/MyGymPartnersAMonkey'' combinds this with TheRival.
