Oh goodness this thread XD
Maybe I misunderstand the meaning of "not feeling real" but part of the reason why I love the KH series in general is because of these absolutely ridiculous scenario/scenes that always make me laugh at their sheer...absurdity? Maybe it's because I am fond of the uncanny juxtaposition, I dunno, I kind of low-key love moments like those. But, uh...here are some things I can remember standing out to me off the top of my head (not including some of which were mentioned earlier):
Across multiple titles:
-The stupidly wide gap that exists in all cage bars that means all the people "trapped" could very, very easily just slide sideways through and escape if they didn't purposefully stick one arm on each bar and woefully bemoan their predicament. (Ven in BBS and Kairi in KH2 in particular)
-The empty bleachers in Olympus Coliseum. WHERE IS THE CHEERING COMING FROM!? Worst offender was in BBS. "We do it for the fanz~!" -Zack, gesturing out to an empty arena.
And actually, while I think about it...
-nearly every scene there are supposed to be "npc" and there just ...aren't. Like Cinderella's "ball", the "festival of fools", etc. Like...as much as Frollo loved to ramble about the menace of "undesirables" on Paris...I only ever just saw him pacing around places ranting like a crazy person yelling about invisible people. I guess unless Esmerelda counted for the entirety of her troupe. I suppose we can give places in the dream world a pass, though because...dreams?
Other moments from BBS (for some reason it feels like this game has the most for me):
-The existence of "break time" ability. I wasn't expecting it the first time I used it and just randomly seeing Terra stop everything he was doing mid-battle to just start doing push-ups had me like 0_0...
-Terra gets "arrested" on the alien spaceship and just...walks out. Because the Keyblade. That will always just be hilarious to me that he's like "I'm being put in jail? Er, okay?.........bye."
-The way Braig jumps away after his confrontation with Terra in Radiant Garden and getting his eye shot off. He does like...five consecutive back hops up the stairs. "Gotta bounce" taken to the max.
ALSO Xehanort's pathetic "heeeeelp I'm tied uuuuup" in that scene (with chains that are barely even over my hands...)
-Terra going on a rant about his darkness and how he failed at controlling it while standing like...half a step away from a bunch of cheery Disney characters all excited about their carnival games and they all just kind of awkwardly stand there waiting for him to finish.
In KH1:
-During the final boss fight with Ansem, part of the very last "phase" when he is wielding that giant spear thing. There was something weirdly unintentionally comedic about the way he would still go "argh, ugh, ack" when you damage him, but his body didn't really react to the hits, keeps floating there, and he only just sort of moves his mouth. And then of course him just blasting himself in the face with light still kind of cracks me up. (Don't get me wrong, the "light" reveal is still pretty epic....but it IS funny.)
-Standing just to the side of any of the "traps" in the cave of wonders and watching your teammates all get smashed by a giant boulder and plummet into a bottomless pit with absolutely no reaction at all.
KHCoM (original gba):
-Vexen's voice/attack sound. I had to pause the game because it made me laugh too hard the first time I heard it.
-Axel saying "hell" and being astonished that they allowed a "swear" word into a Disney game.
KH2:
-This one is a little different, but when you return to Land of Dragons and confront the "organization" member at the top of the mountain (aka obviously Riku) and it is SO OBVIOUSLY Riku (if the weapon or moveset didn't give it away, his general behavior does). That fight isn't so much about fighting the guy as it is about the heartless, but HE CAN ACTUALLY KILL YOU. I tested it once out of curiosity and Riku is ACTUALLY willing to leave Sora cold and dead on that mountain to get picked off by a Heartless. Thanks, buddy.
-The fact that the org's stupidly tall chairs in that meeting room actually move up and down for reasons that are technically canon thanks to Days.
-Maleficent trying to "sacrifice" herself to buy Sora time to flee from the Nobodies in the canyon after the 1000 heartless battle but Sora just stands there and argues with her the whole time and then she just "dies" and he's still standing there like >:[
-That creepy guy obsessed with Struggle Battle in Twilight Town that wanted to see Seifer's "super cool moves" and of course this little gem of a quote...
-Santa claus "losing his way" after walking literally five steps forward into a forest with a total of maybe 9 trees where the exit is in a STRAIGHT LINE from where he came from.
KH3D:
-Sora sitting in an onsen/hot tub with a penguin while the whole hot tub itself flies around and decks enemies in the face.
KH3:
-Tangled world, Sora actually did a "your face" joke to Donald.
-Elizabeth's 'inspiring' speech about going to war to fight to the death with Goofy and Donald just sort of...cheerfully hanging out in the crowd, encouraging her on in the background. TO WAAAAAAR!!
...actually pretty much all of the PoTC world(s) as a whole.
