Undertale: What Alternate Universe (AU) Sans are you?

Undertale Sans. You're more than likely familiar with the character, so instead of getting under your skin enjoy the bonefide bad jokes. Also, don't forget tiba a good person and say bone-jour to all you meet.

The finer details of Fell!Sans differ depending on who you talk to. But some of his accepted traits are that he's crass, a little crude, anxious (due to Papyrus or otherwise), is expected to call Papyrus Boss, and can't take a compliment. He's also pretty darn sweaty most of the time, probably from constant anxiety. He also presents himself much more aggressively than UT!Sans, probably due to the nature of the Underfell AU.

Underswap's creator is Morty (http://popcornpr1nce.tumblr.com/). This AU has everyone's character roles and personality swapped with their foil characters (Sans and Papyrus, Alphyis and Undyne, Toriel and Asgore, etc).

Also known as "Blueberry," he's just as sweet, confident, and innocent--though not necessarily naive--as Papyrus is in Undertale. Though, since he's smaller and rounder, well, he's pretty dang cute. Comics tend to portray him as childish, prone to sugar rushes, and have him assume the role of caretaker that Papyrus normally fills.

Like the Underfell AU, there's no clear original author for Swapfell. Swapfell Sans' personality differs from author to author. Most portray him as aggressive, crass, crude, and just as full of showmanship as the Great Papyrus. He tends to be abusive towards Swapfell's Papyrus--who as a result is more subservient, albeit lazy and kind. He's essentially an adorable little edge-lord who could give Fell!Sans a run for his money.

Outertale's creator is Mimi (http://2mi127.tumblr.com/). This AU retains the same personalities and character roles as the original Undertale, however, monsters were banished into space rather than Mt. Ebott.

Outertale Sans is, well pretty much the same as classic Sans personality wise. However, due to the presence of monsters in space and his interest in stars and sci-fi--and having a larger living space--he's overall slightly happier than Sans classic. It's hard to get too depressed in a vast cosmos.

The instigator for this AU is Buttercupsticksandtricks (http://buttercupsticksntricks.tumblr.com/). It's a mix of the aesthetic of the Outertale AU and personalities of the Underfell AU. (Art is property of Mnstrcndy. (http://mnstrcndy.tumblr.com/)

Outerfell Sans has the same crass, crude, anxious, and aggressive personality of Fell!Sans. Though, he's a little happier and slightly less anxious than Fell!Sans since he has the entire cosmos to observe and comfort him. It's kind of hard to get to depressed as long as you have the stars and space.

Mobtale (Undertale Mob AU, Mafiatale) was created by Amber (http://in-sideunder.tumblr.com/). There are a few different cannons floating around for this AU, however general themes include: Sans is more ruthless and protective over his friends and "family" and a few cannons portray him as an enforcer. He's protective over Frisk and Papyrus especially and is much quicker to violence than classic Sans.

Inktale is created by Myebi (aka Comyet) (http://comyet.tumblr.com/). This AU centers around the creation of Inktale Sans and his ability to aid in the creation of AUs.

Some portray him as desperate to save and preserve AUs and a few comics pit him against Errortale's Sans. His personality varies between happy and enthusiastic to stark realism. In a more realistic light, he probably accepts the inevitability of some AUs to cease.
