* Is this name correct?
* CORETale has not been given an official name; as such, this name is purely conjectural. However, it will be used until an official name is released.
CORETale, or CORE!Frisk AU, is an AU created by Tumblr user DokuDoki exploring the titular character CORE!Frisk and their actions. This AU was the first to coin the term "multiverse" in the fandom, as well as popularize the multiverse theory, and has significantly contributed to the growth in popularity of the alternative universe creation among the fans.
The concept was heavily based on the very popular theory that W. D. Gaster has at some point fell into his creation (the CORE) and became scattered across time and space. In this AU it is assumed that a human falling into the CORE is affected in different ways than a monster would be.
The AU follows its central character Frisk who upon falling into the CORE has attempted to RESET on the brink of being scattered across time and space, which caused them to not only be scattered in their own timeline, but in every timeline. Frisk has gained the ability to be everywhere at once and appear anywhere they want, at cost of losing their RESET powers and humanity.
Frisk's adventure in the Underground is largely identical with the events in the game, specifically its Pacifist Run. Mesmerized, they began to continuously RESET the happy ending just to re-experience everything all over again, not realizing their actions are wrong and harmful to the others - especially Sans, who was aware of the loop they were all trapped in and the fact took a great toll on his mental health. One day as he witnessed Frisk outside of the broken barrier about to RESET the world he snapped, dragged them all the way to the CORE, and threw them inside in hopes that erasing the human from the existence will at last free him from the circle. As the terrified Frisk attempted to save themselves through resetting, their SOUL was directly exposed to the CORE and combined with this and the fact the RESET and the SOUL scattering aligned perfectly, the event has caused them to become omnipresent.
Currently, the story of the AU hasn't further explored what has happened in Frisk's original timeline after the incident. However, it is known that no one remembers the existence of the human and that the Barrier is often believed to have disappeared on its own.
By becoming scattered across time and space, Frisk has gained ability to be everywhere at once known as omnipresence. This means they are able to observe everything in the existence, even the typically unperceivable things (such as colors invisible to the human eye, the atoms, etc.) in all timelines at once, in all of the presents, the pasts, and the futures. They can physically appear anywhere at anytime they wish, however because of the nature of the timelines and the multiverse their chance of manifesting is always exactly 50%, making their involvement in events rather inconsistent and at times seemingly random. It's been hinted that their appearances are overcrowding the timelines with unnecessary splits where they shouldn't be - whether this has a negative effect on the multiverse as a whole is unknown.
CORE!Frisk's iconic grey appearance with two large black sockets is in fact not "them", as they technically don't have a single body. While it is tangible enough to be able pick up light objects, anything above the weight of "plate with a lot of spaghetti" will phase through the child's form. This makes Frisk practically immune to the physical attacks but some things can still affect the form. Their eye sockets are connected among each body currently manifested, allowing Frisk to use them as a sort of "portal" among the timelines for transporting objects small enough to fit through the socket.
While not possessing any flashy active powers, CORE!Frisk is without doubt one of the most powerful characters in all Undertale AUs through their sheer knowledge alone. Because of their omnipresence they are technically a part of every alternative universe ever created, whether they make an actual appearance or not. It is unknown whether Frisk can physically manifest in specialized locations such as The Maker's Punishment, Christmas Party or anti-void, however it's been confirmed Frisk can directly perceive even typically inaccessible places. An important thing to consider is their known involvement with The Omega Timeline, also a specialized location, which would imply CORE!Frisk either simply chooses not to go these places or can only appear if certain conditions are met.
CORE!Frisk is a fickle, enigmatic child who is unable to mentally grow despite their nigh infinite knowledge and wisdom. They appear to have strong personal philosophies about the good and the bad that on the surface don't always seem to make sense - as they are able to befriend the antagonistic Reaper!Chara, but despise the equally antagonistic Reverse Reaper!Frisk. According to the author CORE!Frisk is "the kind of person to break into your car just to turn off the lights you forgot on" which fits into the moral alignment of a Chaotic Good.
To Frisk, lives of the individuals is what matters above the grand schemes of the multiverse. In fact, CORE is of the opinion that the intangible concepts and rules - such as the universal balance - are entirely man-made and following them is harmful to the inhabitants of the timelines. Their belief is so strong they become incredibly condescending towards anyone who values such concepts over the lives of people.
Even though Frisk is incredibly open-minded, somewhere deep down they believe no one understands things better than they do and may subtly treat everyone as such. This behavior tends to amplify the more they dislike someone.
It appears that CORE!Frisk suffers from some form of PTSD, as they are greatly terrified of the sound of sirens, gunshots, planes, and explosive noises such as fireworks. They also get a panic attack and become unable to move properly if they're pointed at with a gun.
Sans is the person who threw Frisk into the CORE in a (successful) attempt to stop the timeline RESETs. While he doesn't directly remember the human, thanks to his special notes he's aware of what happened despite having no recollection of the incident. It appears he still carries resentment towards Frisk and their past actions.
Very little is revealed about CORE!Frisk's Chara so far. It is confirmed that Frisk was unable to see Chara despite the first human being bound to their soul as a ghost.
- "So, go ahead and watch everything from above like some gods, if that's what floats your boat. A person's life might mean nothing to you, but to that person it means a lot. Go ahead and sulk about how you couldn't save them because of fate while I go save them! lol"
- "Some timelines are truly miserable... And then there are timelines where everyone has Mettaton's legs except Mettaton, or a timeline where I'm an octopus. Seriously, what's the point?!"
- "Wiggity wack what's up, pumpkins? I have crafted this totally cool outfit just 4U in order to satisfy your curiosity. ... uh... swag."
- "Your impact is a lot less significant than you think, Sans. You're not special, nor a priority. Definitely not the worst out there."
- "Oh my? I see where this is going. You're trying to make me flustered, or embarrassed in general. Alternatively you want to see whether I'm capable of keeping a straight face during the explanation. I'm sorry to disappoint you, but I'm afraid that won't work. Not with something like this. I'm used to people trying to make me react through dirty questions. Well, I don't mind explaining to you what tentacle incest is, but what's the point? After all... you already know, don't you?"
- An early concept of CORE!Frisk was much darker and disturbing than their current version - their legs were cut off and bleeding profusely, and they had a large wound on their stomach. They were also able to levitate and manipulate electronic objects, much like the amalgamate Memoryhead.
- Their full name is Frisk Marusina, their birthday is February 29th, they're nine years old, and they are four feet tall.
- According to the author Frisk was born in the country of Slovakia set in a near alternative future where it enters a civil war.
- Frisk's personal philosophy was inspired by a single quote from a RTS video game titled Original War, in which one of the minor characters said "I know, [my life] might not mean much to you, but to me it means quite a lot."
- CORE!Frisk has their own in-universe Tumblr blog with username coreo that is described to be "one of the greatest mysteries of the 21st century. [It has] millions of subscribers among which are scientists and historians who keep an eye out for possibly breakthrough updates which will help to advance the humanity."
- They run a business called CORE!Frisk's Dumb Ask Disposal Service, or short DADS, dedicated to removing the unwanted asks from people's inboxes.
- They have dysgraphia.
- Frisk has burn scars on their back.
- In past the author has described CORE!Frisk to be able to absorb souls - a concept which was scrapped completely.
