X-Tale is an AU created by user Yossipossi on the 7th day of July, 2016.


Long ago, two races ruled the Earth: HUMANS and MONSTERS.

One day, war broke out between the two races

After a long battle, the humans were victorious.

The sealed the monsters underground with a magic spell.


The barrier required one SOUL, human or monster, to be given to it yearly.

Every year, the monsters would have a lottery on who died.

One year, it landed on Undyne, head of the royal guard.

She started a rebellion, plunging the Underground into war.

If a single human SOUL was found, it was to be brought to the barrier.

A human SOUL would make the barrier not require SOULs for another decade, bringing peace.

No human has ever showed up, so no one knew what to expect.

Until now.

X-Tale is an AU in which the barrier requires one SOUL, from either a human or monster, to continue functioning every year. If they fail to provide a SOUL, the underground will collapse. Human SOULs stabilize the barrier for a decade. Chara never enters mount Ebott. However, Asriel later dies from other means.

Due to the barrier's issue, Asgore decides a lottery is a good idea to determine who dies. This happens for 5 years, each being usually minor monsters. In the sixth year, Undyne is picked, and is so fed up with the system she makes a rebellion. She, and a few fellow members storm New Home, and accidentally kills Asriel in the process. Undyne and fellow members retreat to Waterfall, as Asgore declares war on them. Quickly, Toriel leaves to the only place not effected by the war: The RUINs. Needleteeth quickly established himself as monarch and cut the RUINs off from the rest of the Underground, as to avoid getting involved.

Muffet, seeing the opportunity to make some easy cash, sets up a border system between Waterfall and Hotland, separating the two new "countries". Undyne makes Sans the official scientist, and makes Papyrus a watchman. Then, Undyne makes Snowdin head of opperations. Meanwhile, Asgore tells Alphys to inhance Mettaton to be a ruthless killing robot with all the latest weapons. Alphys complies. Later, Alphys runs the DT experiments, and surprise surprise, they fail, and create the amalgamates. However, Asgore finds out and uses the amalgamates as weapons against the Waterfallians. Asgore makes CORE the official weapons development and storage area, and makes Hotland the capital. Waterfall enforcers are called Waterfallians, and Hotland enforcers are called Hotlandians.

Oh, and Flowey can't absorb 6 SOULs if no humans fell ;)

RUINs Nothing has changed about the RUINs from the original game. It is the only place untouched from the war. Instead, Needleteeth is king of the area, and builds defences from the outside. No one has attacked. Yet.
Snowdin Labs Snowdin Town has been completely dimolished, and replaced with a facility that includes weapon storage, labratories, and living quarters for military and civilians. Sans is the head scientist.
Waterfall Waterfall is the capital of the rebellion, and has been completely redone. Most Royal Guard members are sent to Waterfall to patrol the perimitter. Most parts of the waterfalls have been replaced with pipes that lead to water filtration systems. The garbage from the garbage dump is sent to a recycling plant.
Border Muffet and her group of spiders control the Border. They have taken control of the spikey mountain, the pathway to Hotland, and where Sans' sentry station once was. They require 99999G to pass as a civilian, but it's free for the military.
Hotland Hotland is the capital of the original kingdom. Asgore had moved it from New Home, mainly because New Home had been infiltrated and could be done again. Most of Asgore's strongest warriors, including the Amalgamates and Mettaton, are stationed around Hotland.
CORE The CORE is the Hotlandian's weapons production and weapons storage facility. It is heavily guarded with force feilds.
New Home New Home is exactly the same as in Undertale, except there is a grave for Asriel in the flower garden.

  • Mettaton has determination in his robot body, for an extreme berserker mode. His DT level is shown by the bar on his chest in box form, and the heart on his torso for his NEO form.
    • He does not have an EX form.
  • In the original concept, Toriel was supposed to be clueless about the war.
  • X-Tale's banner has a shadow.
  • The TP route ends with Flowey absorbing everyone's SOULs, but instead of the 6 human SOULs (which aren't in the Underground), Flowey absorbs enough DETERMINATION from the amalgamates to become ASRIEL and destroy the barrier, ETC.
    • Yes, I know DETERMINATION does not work like that in Undertale, but this is an AU, OKAY!?
  • The most fun making a texture I had was for Mettaton NEO. The hardest was Undyne. The easiest was Asgore.
  • There is a hidden number 1 in Mettaton's screen.
