Disease Sans

“Don’t get my sparing wrong. One of my friends will kill you, and that’s all I wish, but me ? I’ve lost this ability a long time ago...” - Disease
Disease Sans, more know as Disease, or Dis, is a Sans that accidentally destroyed his timeline , and was saved from death by Lucid. As a gift to thank him, Disease promised to help him realize his dream.
== Backstory ==
Sans was free, Sans was happy, Sans... woke up in his bed. The same pattern, over and over. He couldn’t really complain about it. At least, Frisk was staying in the pacifist path, but for how much longer ? He needed to convince them to stop resetting while it wasn’t too late. But all alone, it was impossible. If only he had a way to make the others remember... he stopped. He HAD a way ! In the middle of the night, a skeleton sneaked in his lab, took a blouse (after a sigh), and some notebooks, and with all this stuff, he teleported in the True Lab. "Long time no see, uh ?". 
He started working during days, and nights, he tried to make his idea come true. He often failed, but as timelines passed, he wouldn’t show up and kept working on it. Eventually, he had made it. He had created a vaccine for Resets. Anybody getting injected this would remember every timeline from now. Sans couldn’t wait, but as he arrived, he discovered the dust of his brother. Frisk had had enough of him not showing up, ruining their Pacifist runs, so they had chosen the other path. The one where Sans missing wasn’t a problem, but a miracle. Sans couldn’t let this happen. If Frisk finished this, then, they would erase the timeline, and everything would be lost. His only hope was to force them to reset, and bring back everyone, but for this, he had to be stronger than ever. He teleported to the Judgement Hall, and did what he could do best. Wait. When Frisk arrived, he talked to them, but of course, they didn’t listen. So he got one of the two vaccines out of his pocket, and injected it in himself. 
This was a burst of power. Disease felt the liquid in him. He raised a hand and began to fight. After some simple waves of bones, he decided to go with something harder. He concentrated his magic... And reached the breaking point. It was as if his blood became boiling water. And yet, it was a pleasant sensation. Disease used his soul, and an orange button with RESET written on it appeared. He had did it. He pressed it. 
Everything went black. And then the pain. The boiling determination became acid, it was as if steel blades stabbed his soul. And he reappeared at the exact moment he had left. The Human was standing in front of him, looking confused. Disease then felt something filling his eye socket. It was a liquid, but not tears, or blood. Oh no. As the pain consumed him more and more, he felt his skull flatten and melt. Eventually, it stopped. But a new kind of pain filled Disease. He had the power to only RESET to come back at this same moment. He would never see his friends again. Every attack would force him to melt more. And if he died, he would just come back here, inevitably. He had gone from an unpleasant, but satisfying situation to the worst ending possible. As he fell on the ground, the Human approached, ready to stab him. 
== For the sake of the Multiverse ==
Disease dared to look, and what he saw changed his life forever. A bone had stabbed the Human in the heart, their throat was grabbed by a floating hand, and another was holding their soul. And behind all of them, a strange being, in a purple cloak. They threw the human away, before spawning hands, that floated around Disease, emitting a green light. Disease instantly felt better, but his skull was still the same. "Wh-Who are you ?" he asked. The creature answered in a strange language "☝︎sPA♋︎anPY ⬧︎⧫︎R♏︎UsS❒︎" He seemed a bit lost. 
For months, he often visited him, showed him the beauty of the Multiverse, and taught him everything he knew, and Disease taught him to speak normally, discussed with him, contemplated this beauty with him.
And eventually, Lucid told him about how other universes suffered, and that he had a plan to stop this. Disease wished that he could help him, but all alone, he was worthless, so he thought about this for a long time, and one day, as Lucid was going to leave, he said "I want to come with you. You saved me, stayed with me, and I never had a way to pay you back. I want to accomplish this dream with you. I may not be much, but the more we are, the better, right ?" Lucid stayed silent, and with a movement, he invited Disease to join him.
