Last Breath of the Genocide

Phase 1

(Far long ago, two races ruled over Earth: HUMANS and MONSTERS. One day, war broke out between the two races. After a long battle, the humans were victorious. They sealed the monsters underground with a magic spell.

Many years later...

201X.

Legends say that those who climb the mountain never return. However, unbeknownst to those outside, there is something else that is at stake that caused the monsters problems. One fateful day, a human named Frisk, who is the 8th to fall, went down, and changed the fates of monsters forever, specially...one type of monster that is special compared to the others, named Sans.

Sans is a skeleton that lives in Snowdin. He works as a sentry for the Royal guard and has a younger brother named Papyrus. He lives in a place known as the underground where all monsters lived peacefully, until one day when a human known as Frisk fell down. They had a unique ability known as "Determination" that allows them to control time and come back from death, and they used this ability to repeatedly slaughter everyone in the underground and erase the world before bringing it back. But the runs became so terrible...it split the timeline into 2, back in the past when it involved a certain missing scientist. While Sans remained himself on the timeline that still remained the same...in the other, it was different. Sans, due to the constant genocides, has gone mad and decided to take the human down by gaining the power of LOVE himself. He destroyed and killed most of monster kind to be able to compete with them... but, that wasn't enough even after that. The human kept resetting making the skeleton forget about his mistakes and slaughter his friends again and again.

However, in both sides, there is a door in Waterfall, and while in the original timeline, Frisk opened it, in the other, the alternate Sans opened it. But the results remained the same. A mysterious figure that Sans had worked for in the past, named Gaster. Although both Gasters want the same thing, which is to kill the human, the way they do it and how they treat those that are doing it is different, with one being more ruthless and sadistic then the other. But in spite of this, their goals and care towards monster kind remains the same, even if the other is a little bit twisted in what he does. The 2 Gasters allowed born Sanses to remember what had happened, before they talk to them in aiding them, with the more ruthless Gaster talking of a forgotten experiment that will aid his Sans into defeating the human. Both Sanses agreed with their Gaster's, as they vow to stop the Genocide, and to free themselves from the nightmares they're in. But as that is happening, as the alternate Sans began killing more monsters then before instead of half like before, the alternate Gaster met with the main one when he became interested in the split. The main Gaster did not trust the alternate one, due to seeing how insane he has become, and while the alternate Gaster knows he cannot get him to trust him, he does reason with him in the fact that the both of them are the same human, just in different routes, but are still the exact same thing. Because of this, he requests an alliance, in that the both of them will merge the timelines into one single space, and after that, the timelines will RESET, and all will be normal again, but without the human interfering with their lives. The Main Gaster was skeptical, and knows better then to easily believe that he is in his side, but is still willing to oblige with this, if it meant stopping the human.

The 2 Gasters, using their powers within the void, merged the 2 Judgement Halls together in a point in time, and created a fused area within the 2, which will also fuse both vessels of the human into one single body. When the 2 Sanses met, they hated each other, especially when the main Sans saw the alternate's high LV of 20, as well as the unknown Stats he has, the both of them fought, getting even worse when the main Sans saw the state that the alternate Papyrus is in, but the 2 Gasters reigned in on them and revealed the purpose. Although the 2 Sanses clearly despise each other, more so for the main one, they agreed to align in order to stop the human, since they hate the human more then one another. Putting aside the grudge they have towards one another, both of the Sanses will make sure, that this is the Last Breath of the Genocide.)
