Backstory Phantomtale is basically in a Neutral Route, and Gaster is still a remembered scientist working on his invention, the core, and the player strives to kill everyone except for Papyrus. In this AU, Sans knows about the timelines and how they, Frisk, can basically choose 3 different routes, Pacifist, Neutral and Genocide, and can spare whoever they want, and kill whoever they want. Sans knows this due to having just enough determination to do so. Which is why Sans wants to fight frisk, even though Papyrus is okay. While he fights the human, Gaster decides that enough is enough, and he can't bear to lose his son like this. So, he gets the human souls from Asgore’s throne and begins to rush to Sans to allow him to fuse with the souls. But by the time he arrives Sans is already dying off to the side with a gash straight into his rib cage. Gaster hurries and gives Sans the six human souls souls, but, he rushed, which caused him to accidentally get his soul absorbed by Sans as well. While this process is happening, Papyrus runs in and sees sans transforming into the Sans he is now, and instantly gets stricken with fear, having no idea who he is, but he could sense the power of the souls within his brother. So he ran away. Sans tried to call out to him, but Papyrus didn't listen, didn't even look back. Then, using the human souls, the barrier was broken and he fled to the surface. What he did not know is that Papyrus was nearby, waiting for him to break the barrier, and he fled after him, being sure that Sans didn't see him, taken over by fear and instinct, running away into a nearby forest. Phantom stayed away from others a lot while he was on the surface, out of fear that everyone would hurt him. Personality/Feelings His personality depends on which human soul he is mostly feeling. How can you tell? Well, you can look at his left eye. An orange eye means bravery, Yellow means justice, green means kindness, light blue means patience, dark blue means integrity, purple means perseverance, white means that gaster’s traits are showing, and white with cracks means Sans’s traits. Appearance He wears a long black lab coat with a hood with a blue fluff on the inside to insulate him and keep him warm, under this lab coat he wears a white turtleneck and black, baggy jeans with black dress shoes. He has a grey cloth covering the left side of his eye to look ‘normal.' It covers the crack that runs from the top of his head, to his nose, and down to his mouth on the left side of his face, giving him a bit if a resemblance of his father. Abilities He has the ability to have the human spirits to aid him in battle by sending them out of his body, temporarily knocking himself out while one or more of the spirits attack from outside his body. Phantom, when knocked out, is knocked out in the standing position, like he stopped walking when he sleepwalks, while the spirits become kinda like holograms in front of him. He also has the ability to send gaster’s spirit out, but he is unable to send his soul out, or send out all of the souls but his own, since his soul is damaged and cracked from the fight with the human while in the underground, and needs the other souls in able to keep his soul from growing weaker. His soul His soul is a bunch of faded colors, which fade into each other. first it starts off orange, then fades to yellow, then green, then light blue, then dark blue, then purple, then white, and finally white with cracks. He sleeps by releasing the human spirits temporarily from his body, while still keeping gaster’s spirit inside him. The human spirits are set free so they can have comfort, but they also sorta act like holographic guards, or warners so they can wake Phantom up in case if danger strikes. The human souls act much like cross chara when they are out of Phantom body. They act childish sometimes, but they mostly stay serious and mature when really needed.
