Undertale: REVENGE The Unseen Ending

Undertale: REVENGE The Unseen Ending is an alternate take on Undertale's Disbelief Papyrus. 
== Story Summary ==
The story takes place on another Genocide Route. All acts the same until the human encounters Sans at the end of Snowdin instead of his brother, Papyrus. Sans, who has grown tired of watching his friends die over and over again, attempts to take care of the human at low LV in order to spare his brother's life, but ultimately dies in the end. Papyrus eventually finds out about his death and, with the help of an unknown ally, prepares to strike the demon down once and for all.
== Charaters ==
=== Papyrus ===
Papyrus serves as the main Heroic Antagonist of REVENGE. Papyrus was once a skeleton who was kind and thought that everybody could be a good person. However, this changed after the death of his brother. After traveling through the depths of his mind, he obliterates his pity (which is in the form of a flower). He now sees no good in the human and is ready to avenge the fallen monsters. He wears his deceased brother's jacket around his neck.
=== W.D Gaster ===
Gaster acts as the secondary antagonist of the story and is the possible father of Sans and Papyrus. He is the whole reason that Papyrus now acts merciless, as he is the one who convinced him to destroy his own pity to defeat the human. In Act 3, he takes control of Papyrus and tries to kill the human himself.
=== Sans ===
Sans was the older brother of Papyrus and originally was the final monster the human had to fight in order to complete the Genocide Route. He failed to stop them multiple times and he grew so desperate to the point where he decided to confront them early on in Snowdin, only to be killed once again. His death was partly the reason as to why Papyrus stopped believing in the human.
=== Flowey ===
Flowey, formerly known as Asriel, is the main antagonist of the original Undertale. He refers to Sans as "Smiley Trashbag" due to their past, but he has a much more positive relationship with his brother. For reasons currently unknown, in KDTM's take on REVENGE, he believes he is at fault for Sans dying early on and for Papyrus now being the human's final encounter on the Genocide Route.
== Trivia ==
* The AU originally belonged to Samuel. J, who attempted to make it into a game. After a while he cancelled the project, but he handed the AU over to Pootstablook, who then decided to turn it into a sprite animation rather than a game. Eventually, he cancelled that alongside his other project, Undertale Rusted. Despite this, he still made a video of the progress he had made of the AU. While Poostablook retains ownership of the AU, many people still make projects of their own variations of the project. One of which is Team KDTM, who is doing their own take on the AU with further extensions.
* When Papyrus talks, the Wing Dings Text can be seen behind his font, thus showing him under Gaster's influence.
*In a scrapped intro cutscene to the original REVENGE, Gaster is heard talking to Sans and Alphys. Presumably after a time skip, he mentions his sons. This is highly believed to be Sans and Papyrus.
