NOTE: This is still a W.I.P., I will update it soon with the other characters.

All of you are probably talking about the change in the character's personality for the sake of views or attention but at the end of the day, it's just playing disrespectful to what made the original characters so popular and charming in the first place. And what better way to explain the effects of fan-made flanderisation than Toby Fox's "Undertale"?

What IS flanderisation

Flanderisation (as you probably already know where it came from) is a term based off the Simpson’s character Ned Flanders. The definition of flanderisation is that a small part of a character's personality is shown so much that it slowly becomes their ONLY personality!  It was based off him because in the first season of the Simpsons, he was shown as a Christian but still a loving caring neighbour who never really judges anybody else for their other religions and beliefs (and makes really impressive Halloween costumes) ... but now Flanders has turned into this toxic Christian-obsessed hypocrite forcing his opinion on others and even played God in one episode.

Compare the two and you'll notice the old Ned is a better human being. Designing characters not only has to be unique and interesting but they also have interests and opinions outside of the main personality trait to make them feel more human in a way. Even with silent characters at times like Tom and Jerry, they never mention a word yet they still show their personality through body language and facial expressions.

Yes, that even includes stereotypes! Stereotypes can have personalities too, they can even have interests and opinions outside of their stereotypical trait. If they were stereotypes that always focus on the stereotype part, they wouldn't be interesting, they'd just be hollow.

Now with all that out of the way with, let's talk about why people want to read this, starting with Mr. Undertale himself...

sans.

Most people in the community think that Sans is an edge lord with gaster blasters, a ketchup fixation and tells bad puns ALL the time... he's not. Sans is a lazy sloth-like skeleton who's in his late 20s or early 30s, he has a brother named Papyrus (who we'll talk about later), he likes to pull pranks and tell bad puns at times which everybody enjoys (even his brother, actually). It's not exactly shown if he has depression or not but he is shown to be the prankster of the underground, even for is age. If you think he's the only comedian, you're wrong, there are actually a lot of other comedians like Snow drake senior for example who was shown to be at the MTT hotel. He only drinks ketchup out of the bottle to wind up the player for laughs but he mostly eats junk food in general "like a goblin" (as said by Toriel in the official Q&A), like burgers, fries, mini pizzas, etc.

The only reason he said "you'd be dead where you stand" is either because he either he slightly mistrusts humans but he never actually knows if they're good or not... or he might be pulling on your leg, you know?

There is shown to be a relationship between Sans and Dr. Alphys but it's not exactly clear. The only evidence of that is the bag of dog food which used to be in Sans' room and his love for sci-fi things (that's right, he's a sci-fi nerd, why else do you think there's a telescope?). He doesn't specifically know what happens after a reset but he can tell by Deja vu and Frisk's facial expressions that a reset has happened, though still not sure what happened exactly so he just guesses.

He does have powers... and why? Everybody else has them, even Papyrus so, mystery solved. He does have them but he chooses not to due to his backbencher laziness (Credit goes to @JG_useyoureyes  for that last sentence). And all of you are wondering about the seckrit lab behind the house... I'm not exactly sure why there is one or what the machine behind the cloth does... I guess that's a mystery that people will just have to live with unsolved.

How the fandom treats him is this Ness/Steven universe rip-off with a cal-arts smile and a hypocritical ego. No matter what you do, it's megalovania, no matter who it is he's fighting, it's megalovania, what happens when you litter? MEGALOVANIA! I mean, c'mon! Sans is better than this! Fanon Sans is this overly sensitive cry baby who'll happily fight no matter what! They make it as though he's the ruler of the underground with the powers of a god and infinite health although that's not true, he has only 1 HP, he's a slob whose in-between average jobs and his brother is WAY more energetic and ready for a brawl. Not only that but he's also shown to be a paedophile who'd have sex with Frisk, Chara, Toriel, his own brother, god! WHAT IS WRONG WITH PEOPLE?!

(And the Tumblr sexy man award is just a joke, deal with it).

This is why I'm a lore purist at times, I don't want the sick parts of the fandom taking the wheel because they have no idea how to make a good character.

-Coming up next: Papyrus, stayed tuned for more rants-
