== The Parasite ==
The Parasite is a black creature with 8 tentacles an Eye on the top and a Mouth on the bottom of the creature, the creature will go on a journey to find a host and when it does it will jump on a host so The Parasite can corrupt their soul that will give the host some mutations that are waiting to occur.
==Characters==
Gaster is the main protagonist in this story line with his assistant being Docter Alphys, Undyne play's the part of the commander of the Security Department while Asgore and Toriel being an infected, Asriel will be apart of Gaster's Elite unit and finally Sans and Papyrus are known as Experiment 1 and Experiment 2 since Gaster used the Alpha Parasite to infect Sans and Papyrus and blasted them with more determination to have a chance of creating super soldiers but the experiment failed and they just became anomalies of Gaster's Sector.
== Documented Experiments ==
=== Ex 1 and 2 designated Sans and Papyrus ===
Day 1 Sans and Papyrus are still well normal, they seem to not feel any different yet they have been feeling quite nervous so I guess the effects take a while to kick in.
Day 2. things are still the same as yesterday, this would take longer then I expected.
Day 3. I changed their cell to more playground like one so they can at least stay active while they wait for effects from the parasite, other then that nothing really changed yet.
Day 4. Things are finally staring to happen, today Papyrus started to vomit out this strange purple liquid and Sans started to become paranoid, even though this is exciting news that we finally have effects but you should still be cautious so added more guards to protect the cell.
Day 5. Sans and Papyrus has finally started to get more effects, they both seem like they're melting and they to vomit more of this purple liquid, things are going well.
Day 13. Its time, I put both Sans and Papyrus in the determination extractor, I shall wait 3 days to see more effects.
Day 16. Maybe putting them into the determination extractor was a bad idea, they both killed their guards and breached twice, this experiments was a failure but I can still keep them though, I wont use them as super soldiers, but I will use them for my own purposes.
