Alternate “Nicknames” Info: Sans: Blade Papyrus: Ash ( joke reference to Ash vs the Evil Dead)
Main Plot Synop: Sans timeline has yet to meet their “fallen human”. On the surface the monsters begin to do experimentation learning about the abilities that humans possess. These studies lead to even more advances for the humans and the monsters. They live and coexist perfectly but something goes wrong. The monsters were considered to be pure beings ones with pure white souls to match but humans were flawed. They did horrible things even to their own and eventually that began to create a new threat. One that was easily spread from monster to monster. A black infection that begin to eat away and hollow out ones soul called The Rot. Sans works in the lab spending more and more time trying to help his associates with their research into human soul traits. Gaster begins to make headway on the research of the soul extracting vials of concentrated soul essence. That includes the essence from a fallen human that died of causes unknown. Their name is Chara. In Chara’s soul The Rot lies in wait festering in a sea of pure red. Like an apple rotted from the inside the hate and hopelessness of this trait resided in that lone soul and ate it alive. All that they had been was no more. Those working in the lab are the first to be infected especially their Royal Scientist Dr. W.D Gaster. Sans pursuit to rid the others of this rot causes him to become obsessive and resort to using old vials of human soul essence in his own experiments. It begins to become successful keeping away the infection but at high doses it can have some nasty side effects. He begins to cure the monsters but his own rot can only be cured by one source, Determination. The strength of the essence is so powerful that it begins to have some interesting complications. Kindness- Obsession Integrity- Moral righteousness/ pride/ manipulation Bravery- Adrenaline high constantly sweating, rapid breathing and nausea Justice- OCD (ideologic pride) Perseverance- Extreme fatigue/sickness/ depression as physical symptoms Patience- Timid and intense fear/ anxiety
The Rot and the World it forms: The rot if left “untreated” can cause some rather unfortunate changes within monster biology and the cure to such an infection is not foolproof (in fact I would argue it causes them to start cannibalizing each other). Those that are suffering from the rot begin to make their way through different stages of the infection. Stage 1: Paranoia and weakness
Stage 2: A shift in biology- Due to the cure being human soul traits the side effect is a change in monster biological structure. They begin to lose some of their magical abilities taking on the traits that are curing them. It alters their make up at the soul level. This also causes them to take on a more physical form. That means that their bodies persist after death and even bleed.
Stage 3: Starvation/ Ravenous hunger- The infection causes a craving in the soul most likely in an effort to fill a hole of some kind. The same one that is eating away at their soul leaving a soulless husk behind. This is usually seen in the form of food but it can also be more worldly things. Money, power, all of those are fair game. They essentially become soulless.
Stage 4: Mindlessness- Almost like wild animals the monsters that make it to this stage become like wild beasts. All predators. They feast on other monsters but they usually turn their sights to monsters that have a high concentration of human soul in their bodies. That includes humans as well.
Stage 5: “Death” (amalgamates)- The typical mindless zombie. They are slow and aggressive only thinking of eating even though they are half dead already. They do not speak, they do not think. They exist. (What a horrible way to “live”). Monsters begin to eat and kill each other thinning the once thriving monster world. Just like in UT they used to have an overcrowding problem but now with this new situation that is quickly changing. Asgore locks himself away trying to keep the infection at bay and away from those he cares about. It is unclear if the King is dead or not. All they know is that the entire Underground is in ruin. It would appear that having quantities of these traits can hold off deeper stages of the infection. That is why they begin to formulate ways to lure humans into the mountain, songs, whispers, anything that can be used. The barrier is different in this version as it only requires the power of a human soul and a monster soul to cross it. This means that some monsters have the ability to slip past the barrier to drag humans back for “dinner time”. The human cities have not forgotten about the monster threat and they keep up defenses to keep them out. A zombie apocalypse if you will. That means that some monsters (again not all they have to be strong enough) can cross the barrier and bring back food. The barrier was also not created originally as a punishment for monsters losing the war but rather containment. It was cruel nonetheless and eventually the humans began to distance themselves from the monsters leaving them stuck in a barrier that provided no room to grow and little food or resources. Eventually as The Rot began to infest the Underground humans quarantined it off leaving them even more hopeless than ever before. Humans do not “seem” to be affected by The Rot but their world has been significantly altered by the disease. It makes it difficult to live when all your meals are outside of your cities security and large open spaces are easy targets such as farms. In the end the war and caused an even larger problem, the destruction of their world. It is nothing but an apocalyptic wasteland in most parts due to attacks. Food is scarce both in the Underground as well as on the surface. Just as monsters have become hunters of their own
The Effects of DETERMINATION: Sans begins to see more and more the inner works and the fabric of the world he lives in. It begins to make him think he is going crazy. It has to be due to sleepless nights, heightened stress, and hopelessness that seems to continue to fester in his own soul. In addition to being able to manipulate and see the fabric of his world he also has “visions”. Almost a form of astral projection. His consciousness is able to see through the eyes of his respective timeline counterparts. He is able to see everything they do in multiple timelines. It is a form of timeline hopping or reset. They are all on the same frequency. He begins to see their happiness and their pains. The good and the evil. At first he thinks they are dreams but as it happens more frequently the more he realizes the nature of it. He sees how happy they are and there is one constant variable for their happiness (the bad timelines begin to heighten his apathy). That constant is Frisk. He continues to help the other monsters and almost all of them are “cured” though the other side of The Rot has yet to rear its ugly head. He however becomes a recluse burying himself in his supposed delusions and madness. He continues to take more and more DT slowly turning his eyes red. It is like the ring of an oak tree. The longer that he uses it the more rings he gets the larger his eye becomes (giving him that classic Horror look). At first they are like the rings of a tree effectively replacing his rot with a new DT addiction. It also begins to cause his face to slowly melt. Meanwhile the other main boss monsters that have been treated have a similar affliction where the soul traits they were taken have embedded into their souls. It begins to give them a new power. A power rivaling that of a human soul. The power of the 7. The variable that can be used to slip past the barrier. Sans though is becoming slowly obsessed with this Frisk. He sees her not as a variable anymore but rather someone that will make him happy. Sans madness continues to increase even his associate Dr. Alphys is trying to get him some semblance of help but by this time he is too far gone. He needs an intervention. An explosion happens in the lab. The vials and his research are now gone. All of it has gone up in flames and unfortunately the damage to his soul has already been done. He ends up in solitary confinement sinking further into his obsession. News reaches him that a human has fallen down from the opposite entrance of the Underground. He goes to meet them only to realize that they look nothing like the human he is obsessed with. He begins to harvest human soul essence hiding his face behind a mask at first since nearly the whole front portion of his face is gone. It is a mask of his own face which makes his gaze even creepier knowing what, or rather what does not lay beyond it. Eventually he learns to easily control his face with his magic rearranging the dust to shift his appearance. His level of insanity shifts to obsessive confusion. He is unhappy his first human encounter is not his precious Frisk but the human does have her eyes from his perspective. His concept of what Frisk actually looks like keeps changing. His form and control is directly tied to his emotional states. If he experiences any form of heightened emotion be it sadness or rage his composure will falter as will his appearance. If it becomes too drastic he will slowly begin to melt causing the appearance he originally had when this all began to appear. This is why he is called “The man with many faces.” He will sometimes end up completely faceless save for the bottom half where his grin would be.
Blades Madness: Sans (aka Blade) obsession causes him to steal the various parts of humans to create his perfect human. Each one he makes he sees as an improvement. They are all mindless dolls held together with low doses of soul essence and magic. A macabre shrine to his beloved human. They reside in his shed and sometimes he talks to them but he considers them as failures. He calls them his projects and this continues over and over until his Frisk falls. He is overjoyed that he has his precious with him now. Papyrus checks on his brother yet he knows he needs help. After all these years he has seen his brothers decline Ash tries to help him. Frisk’s entry into the Underground is by complete accident, though she is not the savior that the rest are known to be. She is a soul of kindness causing her eyes to be a bright jade. Even Sans though overjoyed that Frisk has “returned” to him; he feels as though she is not perfect yet. He takes her and makes her perfect by removing one of her eyes to be a beautiful blue. He even cuts the back section of her hair to satisfy him. She feels no pain when this happens. Her kind soul wants to help him and slowly she begins to pull the old Sans back every once and awhile. They are glimpses but it is progress.
