This project started with a short animation created by Jael Peñaloza (Underverse and Cross!Sans creator, also known as JakeiNimation). The main storyline is about a Sans that came from a mysterious and corrupted AU, having inside Chara’s half determination, they will travel for many AU’s to infect them with the X-Event, a power that will corrupt those worlds and will restore their own.
The inhabitants from the AU’s will be involved in this story, trying to stop Cross!Sans and Cross!Chara in order to discover the meaning of his existence and the true meaning of the X-Event.
List of AUs (Including Undertale post-pacifist timeline) that will appear on this animated series (It will be on constantly change, also there are Characters who don’t have an official AU.)
Ink and Error have been fighting against themselves for the Multiverse existence. Error has found the Doodle Sphere, an access to all AU’s. Ink will try to stop hem and make fun of his eternal friend/rival. However, both skeletons will be taken by a strange force to a empty, huge ocean with a little piece of island. Both are not able to use their powers and come back to the multiverse…It’s time to find their own worlds and end with that pointless war.
The Multiverse Balance is about to start by itself thanks to their truce: Don’t destroy and don’t create AUs anymore.
Error and Ink are now almost friends, but the artist skeleton doesn’t feel so happy. He can’t motivate people anymore…
Ink will find a new friend and both will make a promise.
ABOUT X-TALE
X-Tale is an Undertale Alternate Universe (AU). This world started just two Humans and one Monster:
Xtale!Frisk, Xtale!Chara and XGaster.
XGaster was the responsable of creating the huge XTale thanks to his power: The [OVERWRITE] button. He knew already the existence of the other monsters. But he thought they were their own creation.
XGaster wrote the full story of this AU. All monsters and humans lived together in the Surface. Asriel was alive, Frisk and Chara were adopted by Toriel and Asgore. There was the perfect story, the perfect world for everyone.
But XGaster got bored.
With his power of Overwrite, he could make something better than a Reset and create timelines, He corrupted the same AU’s code, modifying people’s behavior, powers, the appearance of places, monsters and humans, even writing their own way to die.
Frisk and Chara grew up. Each time they reached their adolescence, their loved ones died by the pass of time, by diseases, by suicides, accidents…RESET by RESET…each people’s story was the same because of XGaster. With both DETERMINATION souls, Frisk and Chara decided to fight against him, trying to stop that terrible nightmare.
They failed.
XGaster Overwritten their souls, mixing them into one being. He wanted to create an experiment.
Cross!Chara became in a part of Cross!Frisk’s soul and body, and they would never grow up anymore, then, he gave them a new chance, a new power better than RESET, so he took Half of his OVERWRITE power and introduce it into their new core code.
That experiment would be the Prototype of the X-EVENT.
Frisk and Chara, now called as the “Experiment” was able to modify and reset anytime, only by XGaster’s approval.
–
XTale was modified Ten times, where people and story were a Pacifist, Neutral or Genocidal route. If the Experiment tried to Reset. the timeline wouldn’t be affected and would have the same route assigned.
The Experiment began to feel Sorrow and Frustration.
The last timeline written by XGaster. His masterpiece.
The experiment tried to modify this timeline, but it was hard since he was being chased by other humans and always under their friends and family protection. He was incapable to show his power, because he loved them. They loved them so much.
One day, the Experiment could restore part of the main core code of Sans, bringing them back his Genocidal memories.
– To be continued…
WHO IS CROSS!SANS?
Better known as “Cross” or “C”, is an Alternate Sans from the X-Tale Universe. In the Timeline Number Ten, he was trained along with his brother Papyrus to become a Royal Guard in order to protect Frisk after they broke the Barrier and brought peace between humans and monsters. His Genocide core code was restored by Frisk, obligating him to destroy him forever, releasing the true X-Event that was inside him, taking the form of Chara. Cross destroyed half of Chara’s soul and sealed it in his own body to prevent a new Overwrite and hurting somebody else again.
Cross feels ashamed about his Royal Guard costume.
His real name is Sans, but Frisk gave him the nickname “Cross” because of his clothes design and his desire to create a new AU and a new Timeline with the OVERWRITE power.
X-Gaster is his father. He always tried to get away from him.
Cross was a energetic and happy person, He never was a lazy bones.
They had knowledge about the main Timeline thanks to his Frisk (Undertale)
His blood color is purple, as well as his tears and when he blushes.
His favorite food is Chocolate
He also likes Tacos when Ink show them after seeing a drawing about it.
Cross is afraid of cows because of their sound. The fear is bigger when he sees a black and white cow.
When Cross is sleeping, Cross!Chara can take the control over his body, even if he doesn’t have a physical soul. (Chara is only Determination inside Cross’ body)
His soul can be extracted out of his body when he is distracted and receives an attack or even a simple hit.
CROSS HABILITIES:
HACK Knife
It’s a hack programmed for Cross!Chara. With this weapon, it allows Cross!Sans to break Au’s main code and get access to it. Also, they can corrupt people or objects’ codes.
The normal appearance of the knife is gray, as a normal iron knife, but when they are going to corrupt the codes, it turns into a flashing red.
Cross!Sans can use his own powers (Gaster Blasters and Bone attacks, despite they’re have been corrupted too). When Cross is decided to use them, the color of his magic in his left eye is represented as purple-white (top-below)
Cross!Sans can’t travel to other AU’s for his own if he doesn’t get first an access to their main code or “routes”.
> Ink!Sans, Error!Sans, Nightmare!Sans, Dream!Sans or another Sans that can travel on the multiverse is the only way for him to discover those routes. > When Cross obtain knowledge from an AU, he can go there every time he wants, altering it temporarily or even “stealing” part of the main code to move to his own universe.
CROSS’ XBLASTER CONCEPT
WHO IS CROSS!CHARA?
Cross!Chara or Chara is a part of the X-Event prototype that survived when Frisk was destroyed by Cross. His soul still having the trait of Determination, but also he has the power of Overwrite. A forced modification of Reset.
He is now a half of Determination in Cross’ monster soul, represented as a human’s half of soul. Chara is the responsible to giving Cross the X-Event ability. But Cross only uses it for rebuild his world. Chara wants to use his full power to Overwrite all the AUs and creating just one timeline in the entire Multiverse when he can obtain another human soul.
Before the Timeline number Ten, Chara and Frisk had their own bodies. Both could reach the age of 18.
His current appearance is his 18 years old into a 10 years old version, because is the representation of his mind and soul, not his body.
His true child body is shown when he takes a human soul.
The Overwrite power prevents Chara and Frisk to growing up.
Nobody can see Chara, except for other humans and Gasters (Only Ink, Error, Underswap!Sans/Papyrus/Chara, Nightmare and Classic Sans know about his existence).
His right eye is covered by his hair because of a scar made by XGaster as a result of the X-Event prototype creation.
When Error!Sans took their soul, both Cross!Sans and Chara lost control over their body, corrupting themselves and turning into an unstable being, having only few hours to live thanks to Chara’s determination.
They’re fighting for the body’s possession, changing their appearance every time (Chara’s body or Cross’ body). Thanks to Chara, Cross was able to take half of Classic!Sans’ soul and recover their physical body.
With a new Sans’ soul inside, Cross recovered his body and He has full control. Chara only gives him advice and The X-Event Power to accomplish their purposes.
