These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Donald Duck
Archive Panic: We're talkin' about a character who has appeared in a considerable quantity of videogames, thousands of newspaper strips, a frickin' helluva lot in animation, and an absolutely monstrous amount in comic book stories...which have been released in a non-stop basis since 1934 and are unlikely to ever stop as long as The Walt Disney Company operates.
Moral Event Horizon: In "Donald's Happy Birthday" Donald sees their nephews buying a box of cigars and wrongfully thinks that they want to smoke, when they actually wanted to make a present for him. He becomes furious than ever and decides to punish their nephews forcing'em to smoke the entire box of cigars at once in their tiny treehouse and even increases the smoke with a bellows. Even when they pass out all sick and exhausted Donald triumphantly yells for the boys to "have another cigar!" While Donald were a jerk in some circustances, but still holding some sympathy, here can be considered downright cruel.
Nightmare Fuel: Donald going mad with godlike power in "Trombone Trouble". Along with him saying, "Power, power, POWER!" and then laughing evilly. The sharp teeth certainly didn't help when he was laughing evilly.
Donald roaring and taking a huge bite out of wood in "Donald's Double Trouble".
Donald literally turning into a devil at the end of "Soup's On".
Thanks to them editing the context, the prime time special "Down and Out With Donald Duck" treats Mickey's treatment of Donald in the short "Magician Mickey" as a moment that's left Donald severely messed up and revealed that it still gives him nightmares.
Donald believing that he's accidentally amputated his entire lower torso a which leads him to be nearly Driven to Suicide complete with an insane Slasher Smile on his face the whole time in "The Old Army Game."
"Donald Duck And The Gorilla". Donald having to deal with a monstruos Killer Gorilla who breaked into his house.
Older Than They Think: The name Donald Duck first appeared in a written poem, More Hoozoo in 1931. (However, the illustrated duck did not resemble the character as we know him.)
We're Still Relevant, Dammit: In computer.don, Donald is depicted as being pathetically behind the times (having a rotary phone and an old fashioned ice box that Goofy stops by to refill), and is repeatedly labeled a dweeb because of it.
