Fellswap 2020

Fellswap 2020 now has its own official Soundcloud page!
Fellswap 2020, also known as Canon Fellswap, is an AU of Underfell where the roles are swapped, but not the personalities or the appearances, although they are minorly changed to fit their roles. Therefore, for example, Sans is still lazy and less evil than the other monsters, but he is now weaker and wants to capture the human, due to being in the ambitious role, while Papyrus is still energetic and harsh, but he is now friendly towards Chara (who is swapped with Frisk). The personalities of their non-swapped versions are given more focus than their roles, so for example despite Underfell Flowey being friendly and damaged, Fellswap Temmie is evil and well-dressed, due to Underfell Temmie's traits having priority.
==Characters==
Please note that most characters are only designs, and many are fan-made or outdated, so if any new canon designs or info appear this will be changed!
===Chara===
Chara's personality is likely the same as theirs in canon Underfell, making them a very kind and hopeful child who always has a smile. In their current design, they resemble the Chara of Underfell, but with pants. 
===Temmie===
Temmie's personality is likely the same as theirs in canon Underfell, meaning they act like a vicious businessman or a banker, and speak in perfect English. They look like Undertale Temmie, but they wear a dark red pinstripe suit and a large glass monocle that is not a robot eye, and they have an evil expression. They act helpful and nice for the whole game, but are only in it for personal gain, and would not think twice about betrayal, meaning they likely have a Photoshop form. They are afraid of Asgore. Their themes: https://soundcloud.com/very-epic-fellswap-moment/bad-tem
=== Mettaton ===
Mettaton's personality is likely the same as his in canon Underfell, meaning he is glamorous and evil. He sets up traps. He is a red tattered sheet with the black hair of his EX form, four yellow eyes, four yellow floating hands, and a large smile with yellowing teeth. He is male. Themes: https://soundcloud.com/very-epic-fellswap-moment/deathly-debut
===Asgore===
Asgore's personality is likely the same as his in canon Underfell, with some changes to fit his role, meaning he is a once-powerful tyrannical king who wants the human to stay with him. He looks the same as Undertale Asgore, but with yellow eyes, black hair, longer horns, a Toriel-like robe, and Underfell Asgore's pants. He uses a trident. His themes: https://soundcloud.com/very-epic-fellswap-moment/erbarmlicher-welpe https://soundcloud.com/very-epic-fellswap-moment/conflict-of-a-blazing-soul
===Sans===
Sans' personality is likely the same as his in canon Underfell, with some changes to fit his role, meaning he is lazy and evil but wants to capture the human. He remembers resets, but honestly doesn't care anymore. He joined the royal guard because Alphys thought his fighting skills were amazing, and Papyrus pressured him a lot. He refuses to wear armor or use weapons because he "doesn't need it". He talks in lowercase. He resembles Undertale Sans, but he has fangs, a gold tooth, a constantly glowing red eye, a tattered black cape made out of jagged smoke like material, basketball shorts and shirt with gold detailing and a number "20" on the front, gold rings with red gems, and his hands in his pockets on his shorts. His shoes are now black.

===Papyrus===
Papyrus' personality is likely the same as his in canon Underfell, with some changes to fit his role, meaning he is energetic and evil but wants to help the human. He has the same powers as Underfell Papyrus, but very buffed, with them being much faster, more advanced, and more damaging. He cannot remember resets, and instead fights the human on genocide as a way to "punish" them after they have gotten his friends to kill eachother. He helps Undyne with her inventions, with varying levels of success. In earlier versions of AU, he forced Grillby to give him his jacket since it's fashionable, but in the current story it is simply a biker jacket he bought. He owns a motorcycle that he rides around which he named "Beauty", but Sans likes to call it funny names starting in "St-" like "Steve" and "Stuart", which drives Papyrus bananas. He speaks in Uppercase. He wears black pants with purple boots, red socks, a Wrestlemania belt, a leather jacket, and a hip rainbow-camouflage shirt, which is tight enough for some of his bones to be visible. He wears no gloves, but he has several gold chains, with one around his neck and another hanging off the bottom of one side of his jacket. He has evil eyes with the left one having a scratch (and possibly glowing), and a zigzag line for a mouth which goes across his whole face. His jacket has pockets, but his default pose shows him standing with his legs apart, and his hands holding on near the the top of both sides of his jacket, as if he is pulling it open, or with his hands at his sides. He sometimes wears a biker outfit with a skull and crossbones when riding, which Sans likes to compare to an Among Us Imposter, much to Papyrus' annoyance.

===Alphys===
Alphys looks like how she does in Undertale, but with swirly glasses, armor like Undertale Undyne's, and red high heels. She leads the guard, and let Sans join when she saw how he fought. She and Undyne are likely lesbian in post-pacifist. She wields an electrified axe, not an axe made of electricity.
=== Undyne ===
Undyne looks like how she does in Underfell, but with a torn black shirt with a red broken heart design, a long puffy dress with a pointy bottom and a red belt, a dirty labcoat which she keeps her hands in, golden bracelets and earings, and a yellow cyborg eye. She has much more hair. She and Alphys are likely lesbian in post-pacifist. 
=== Napstablook ===
He is a DJ, and his body is a creation of Undyne. In his battle, he will lose his legs first. His design is very complicated, so one should consult the gallery.
