Here is a guide on how to make an Undertale OC that's not a cliche! With your cliche-made host, Castellar!
Castellar: Alright, alright. Now, us at the AGC have a big thing about cliches! We HATE them. So, with your cliche-made host, me! We'll get onto business.
SKELETONS ARE ALWAYS HUMANOID. WHY?
Now now, my group fall into this one because we're always humanoid. But, there's a reason, multiverses is our reason, we our busy people, humantale says all this! But * holds up a copy of Minecraft * Nether the less, if you don't have any AU equivalents, why not try something like, a duck, or a cow or a fish or like a... platypus? Yeah, one of those things. It would make sense! ey? 'n' hey, ya guys look at Forte? He ain't a skeleton!
SKELETONS DO NOT HAVE TO BE NAMED AFTER FONTS!
Well, if my creator wasn't so font-obsessed as he is, maybe, we'd not be named after fonts. The only one that isn't named after a font is Gus... but... y'know... he's referred to as a font so... there's there I guess. STILL! His name is Gus, that's what we stick with! Anyway, they don't HAVE to be named after fonts, they can be other names like... um... programs? Yeah, go with that, programs! Like... I d'know um... MEMZ? O-One could be called Memz? There. Not only that, just don't make your character related to them in any way, it's just a no no. I guess this isn't really the biggest call because, I mean, fonts are infinite, its like, everyone wants a font-named OC.
DON'T MAKE YOUR OCS APPEARANCE SHORT, PLUMP AND HAVE A CONSTANT GRIN
Woah, hey, not even I fall into this one and ya don't see Gus and Showcard with a constant grin, it's just ther image, they want to look nice, not only that, they aren't even plump! They're perfectly normal. So, if you go 'round makin' ya OCs look like a Sans even from the outside, ya in for a bad time! I mean, skulls? D-Do we really need to discuss skulls? Sans skulls are fine, it's not like ya need a Sans skull to make it a rip-off. Also, I mean, not every single one of me friends has Sans skulls, Calibri, Calisto and even meself all have different skulls!
ONE GLOWING EYE! THAT ONE GLOWING EYE!
How interesting, a glowing eye? Come on, ya can't be that lazy! Not even I'M that lazy and I'm more lazy than that SwapSwap chump. Anyway, even I don't have one glowing eye! I have zero. Gus has zero, Showcard is constant, Calisto has both in his pupils, Forte has zero, Calibri has zero and... that's it. Ya know, it's just, make up ya own stuff, no need for an eye to glow in the dark!
SKELETONS HAVE THEIR OWN LITTLE GASTER BLASTERS. HOW CUTE?
Oh, come on, do I even have to start? Most of the gaster blasters are just crappy recolors or a slightly different designs with horns stuck on in any random place. It's too lazy for words, man, too lazy for words.
SKELETONS CAN MAKE MAGIC TOUNGES AND HAIR ( And genitals... apparently... )
I mean, excuse me? Who does this! It's not like somebody went to Star Wars, got a lightsaber and shoved it down their pants, I mean, this is something SHOWCARD would do just to turn people on! But, like, really? Do I even need to explain? Does your little skeleton creature have to turn every fangirl on? It's just a no no! I'll pass on with a skeleton wearing a wig, cause that's cute, but, since when in Undertale does Sans's stuff glow? It's just, wierd, dude. Unfortunately, I'm too lazy to continue, so, I'll probably be editing this soon. But, y'know, anyways, see ya later, platypuses!
