Backstory:
In DAU, Lust Sans had forced himself to be less lusty(which would cause problems later down the line of course), a few days after that happened he started getting a voice in his head and a new reflection, Crust, Crust started out confused and 'innocent' at first, but Lust soon noticed that he already knew a lot, though, he showed no signs of trouble then. As days go on, Crust longed to meet the others and talk, so Lust let him take control, but, for the worse, Nightmare and some others pissed Crust off while he was in control, Crust had the wonderful idea to....Blow up Nightmare's room with him inside. Lust got into a lot of trouble after that. Lust kept giving Crust chances, which led to problems. Lust finally decides to put his foot down and doesn't allow Crust to take control, Crust was furious and showed Lust that he can very well tamper with things even inside his mind by angerly shattering a mirror. Since then he had been forcing control whenever he wants, after making himself known, some have giving him the name "Crust", which stands for Creepy Lust, he didn't pick nor like the name but he was too busy to deal with it, so he was known as Crust by everyone. He met Natsuki, from DDLC, and quickly became friends, she soon fell in love for him(mostly because she just got out of a bad kinda one-sided relationship and was very emotional), and helped him find a way out of Lust's head, when he was freed, he got his own look yet no soul, since Lust and him shared the soul Lust was born with. Crust was then shown to everyone and was soon seen as a threat, for he could somehow, on his own, take down both Error and Nightmare first try, this led people to stay away from him, but oh, Crust wasn't done. Due to the mixed fandoms and 'snaps' of people, he was easily able to get three new evil sides from Classic, Swap(Blue), and Dancetale Frisk, who's names soon became Melting, BlueScary, and SDT. He loved his new friends and his new girlfriend, Natsuki, very well and despite not having a soul, he was very loving and caring to them. He and his group(other than Natsuki) turned into the "New Bad Sanses", they all hated their counter parts so they would constantly come out to attack. As his group grew in numbers he began to have nightmares of the others defeating his group and killing them, also losing Natsuki and Sayori, both Natsuki and Sayori still were friends with those on the other side. Some in the AU such as Gaster have tried to figure out what Crust and his friends were and what they stand for. One theory being that Crust is the self-hatred and anger Lust had for himself just given form.
Ref: There is no ref yet, I'm waiting until I can do it online and well.
Note: I just did this for fun and I don't expect people to like it, I've had this OC for a while now and he's been talked about some on my YT channel, if you wish for this to be taken down I'll willingly do so since I really do not care if people like him or not.
P.s. Sorry if you had to read it all grouped up, I'm new here and it won't stop being one long paragraph for me. So sorry.
