Plot[]

Before the Beginning.[]

On a distant Planet called Pandora, there was a mountain called Ebott. A young child had fallen into the mountain, trying to escape from the world. There he was found by a young siren named Asriel and taken by the Dreemurr family, and raised as their adopted son. Despite the Dreemurrs pure intentions, this child was anything but, and as the months went by, this child planned to steal the power of monsters and claim the riches of the underground, in a plan to return to the surface and purge the planet, and so he attacked his parents, kidnapped his adopted brother and vanished into the night, not to be seen ever again.

A decade has passed since then, as another child fleeing from the bandits of Pandoria meets the same fate and falls into Ebott.

Beginning.[]

(To be written)

Neutral End[]

The unnamed Protagonist breaks into Central Command with the help of monsters where they Find Chara, who has strapped Asriel to a machine (Resembling Omega Flowey) in order to turn him into a mindless weapon of ultimate power. Chara engages the Protagonist in order to claim the last and final soul to complete their goal, but is denied by not only the Protagonist's capabilities, but by the main monster cast defending them. In their frustration, Chara forcefully merges himself with Asriel and the 6 souls, with his conciousness taking control of the resulting fusion. As the fight goes on, The Protagonist then convinces both the 6 souls and Asriel's soul to revolt against Chara and forcefully eject him back into his own body, at which the Protagonist then can choose to Kill or Spare Chara. After the choice is made, depending on the Protagonist actions thoughout the run, the ending will change.

Dark End[]

The Protagonist destroys the entrance into central command by force alone, to which they find Chara, and he offers them to join his side and obtain ultimate power, The Protagonist declines and attacks Chara, the ensuing battle knocks Chara into the machine, causing the machine to malfunction, and explode into a determination bomb, killing Asriel inside the machine, and turning any remaining monsters into horrific amalgamates, in the remains of the explosion, Chara and The Protagonist fight one final time, upon which the Protagonist kills Chara. The Protagonist limps towards a throne made of scrap metal and the collapsed central command and sits, as the moans of the amalgamates and the atomized remains of fallen monsters blows around them.

Locations []

Frostwaste (Ruins)[]

An area of unforgiving cold, littered with bodies of the unfortunate that don't survive the tempratures, or charred from the monsters who have no mercy for the wicked.

Sanddune (Snowdin)[]

A humble desert town, in the middle of a sandy desert, while the monsters of the dunes are violent, those who live in the town are significantly less so, protected by a pair of brothers who more or less try to keep some kind of order.

Sheercliff (Waterfall)[]

A series of cliffs, with the occasional waterfall. Inhabited by very few due to the difficulty to traverse, and those who do hide in fear of the inconherient screams of lunacy.

Toxinlake (Hotland)[]

Once a Beautiful lake, now turned into a place of toxic runoff coming from Firefactory due to their mass production. Here lies a junkyard of scrap metal and objects, where one rummages through for their next greatest creation.

Firefactory (Core)[]

A large towering building, inside, enslaved monsters and machine work together in unison for a sinister cause while the building burns with heat and fire, creating new machines to cause havoc for the rest of the underground.

Central Command (New Home)[]

Deep inside of Firefactory lies a mysterious stucture, entry forbidden by monsterkind, occassionally screams and cries for freedom can be heard, hidden inside are valuable items Chara has stolen from monsters through his EXPbots.

Trivia[]

  • Monsters in this AU have real tangable bodies and physical matter, while still not as sturdy as humans, means they do not turn to dust when someone dies. They can still become Amalgamates though determination, but unlike standard Undertale monsters, it takes much higher levels in order to do so. (Regular human levels of determination can cause monsters to still melt.)
  • There is a concept of level in this AU, marked as lvl, while LV and EXP terms still apply, lvl would be raised through experiences and knowledge, harming non-sentient EXPbots will not affect The Protagonist's LV, LV is only raised when harming monsters. Lvl, affects their health exclusively while LV affects the damage they can do.
