Jason Backstories+More information

I'm here to explain Jason's story and more characters in this part (Some characters might be OOC)

Classic Jason's Backstory

Jason was a skeleton just like Sans and Papyrus even his brothers Zeron and Cyon was skeletons as well but due to an experiment gone wrong in the past Jason, Zeron and Cyon got turned into humans but were still able to use their skeleton forms timeskip to the near future is where Frisk fell down and saved everyone Jason was happy about that and was finally out of the underground that is until an unknown entity takes over Frisk body. Jason learned something was wrong with Frisk after the 10th genocide route he could see that Frisk was hesitant when killing "monsters" and had tears in her eyes while fighting him and Sans he decided to do a bit of research and what he found shocked him an unknown entity that can possess a DETERMINED human soul Jason put two and two together and realize that Frisk was being controlled by this same entity he tried to tell Sans but he just didn't care and thinks that it's all just Frisk's doing. During the routes Jason tries to help Frisk by beating the entity out of her much to Sans confusion sometimes he would try and stop Sans from killing Frisk and telling him that an entity is doing this but again Sans doesn't care. After Frisk regained control of her body Jason confronts her asking questions about the entity and if she was ok of course Frisk wasn't but said she was ok Jason doubted and told her that he is the only one who knows the truth Frisk was happy about that.

After Frisk saved everyone once again and gave all of them their happy ending Jason was happy and wanted to get to know Frisk more before the entity took over. On the surface Jason can see Sans and Chara hate Frisk so he would keep her away from them much to Sans and Chara confusion timeskip to a few weeks later is when the entity aka The Player appears and tells everyone the "truth" of course Jason doesn't believe it and tries again to tell everyone, but they didn't listen to him. Jason was the one who protected Frisk much to everyone's confusion he yelled at everyone especially Sans, Papyrus, the entity  and his brothers. Jason took Frisk and teleported out of the house and went back to Snowdin where he hugged a crying Frisk, he took her back to the house that the skeleton brothers reside in before and stood by her side.

Dust Jason's Backstory

After 300th genocide routes that The Player did both Jason and Sans snap and took matters into their own hands they killed their friends and brothers in hopes to stop the human and they succeed timeskip to where Sans and Jason join Nightmare with the other bad Sanses and Jason's. On one of his missions Jason snapped out of what he was doing thanks to the phantom versions of his brothers and he gained a bit of his sanity back, once he learned what he did to his friends and brothers he was drowning in guilt. Just like Classic Jason he also learned that this entity was using Frisk's body to do the genocide routes which made him even more guilty. Jason told Nightmare and the others that he was going to find more victims to "kill" and they let him go but Jason never came back he went back to his and Sans timeline in hopes of reviving Frisk. Jason used a piece of his soul and another soul he took to try and bring Frisk back after a couple of tries it works and Frisk was alive again but she didn't have the reset and save ability anymore she was happy to see Jason again(For those wondering why she isn't scared of him or hates him because she didn't have enough DETERMINATION to fight back against the entity aka The Player and knows that either Jason or Sans would have found out she also doesn't care if Sans and Jason killed her since she thought it was for the greater good of course she still is traumatize from the genocide routes) Jason kept on apologizing over and over again but Frisk didn't hate him so he swore to himself that he would protect Frisk and kill only if necessary.
