W.D. Gaster

Description:
W.D Gaster is one of the many villains in the Janecord Tupperbox RPs. He is a humanoid figure with two cracks on opposite sides of his face, an eerie grin, and a semi-melted body, due to being overdosed on the rare substance "Determination." (He looks like a buttplug.)

Main Story:
W.D Gaster was once the Royal Scientist back when the monsters were trapped under Tupperville. He secretly experimented on the humans who would fall down and were killed, later on extracting a power called "Determination," which is an energy helping the body persist. However, when it is applied to the monsters underground Tupperville, they will begin to melt, not being able to control the power Determination has.

Despite his most famous creation being "The CORE," he also created a machine that could power up and extract beings with Determination, literally named the "Determination Extractor." His (now former) work colleague, Sans, helped him for a period of time before realizing what he was truly doing. Gaster was using the Determination of the fallen humans to fuel his extractor, and then use said extractor on innocent monsters to cause them to melt and combine into conjoined, yet deformed beings named "Amalgamates." After Sans found out about this, he decided to give Dr. Gaster a taste of his own medicine by turning on the extractor and then pushing him into the firing range.

Due to the intense amounts of Determination, Gaster's Soul was destroyed in the process of it all. However, as stated above, Determination gives the body persistence. Despite his soul being shattered, he still "lived" on, literally filled with Determination. Due to this, he found himself in an empty abyss between life and death, which he resided in for years, reshaping it his own world. After enough time of gathering enough power...he was ready to return.

S.O.O.V Attacks Arc:
Upon his return, he joined S.O.O.V, one of the first villain teams in the Janecord Arcs. He managed to defeat Sans and take his secret machine, which they used for their own evil purposes. However, it appears Gaster only wanted Sans gone, as he did not help out with S.O.O.V's attack on Tupperville. After the attack ended, Papyrus caught on to what was going on, and fought Gaster for his brother. They fought in the void, as Gaster sent both of them into the Abyss, where he reimagined the CORE, Gaster's prized creation. In a turn of events, Papyrus pushed Gaster down it, causing him to seemingly die. Instead, he was once again shattered across time and space. After 2 months of floating around in nowhere, he appeared in a completely different dimension...

Back To Zero:
Gaster awoke in the 10th Dimension, a different reality where character's roles or personality traits were altered. There, he found the Alternate Candy and Braixen of the universe, both scientists trying to restore hope to Tupper City, hope that Phantom Blot (10th Springbonnie) and the rest of his gang had stolen from them. The scientists, along with Alternate MCV, had experienced dreams of the original dimension, causing them to research into the possibility of alternate universes. Gaster, knowing they clearly existed, due to being sent to this one, was planning to assist the scientists in their goal. However, he doubted they trusted him yet, so he remade a smaller version of the CORE for the 10th dimension, restoring a fraction of hope to Tupper City. After that, the scientists told Gaster about the alternate dimension concepts. Gaster proposed that with enough research, they would find a way to enter these alternate dimensions via a portal. This got the scientists working. After an extended period of time, they got it to work. As soon as the portal was complete, Gaster used a device to absorb the energy of the portal, causing him to transform into a nearly omnipotent being. He then began to terrorize Tupper City, taking away the hope he once gave them. He then escaped through a portal once 60% of Tupper City's population was eradicated.
