In this au it takes place in bills old dimension. Tad, kill, will, bill, and maybe Jill are siblings ( if you want you can't imagine tad being the cousin) also the age kinda matters depends. Tad is the oldest then kill, after kill is Bill then will a few minutes after(twins) and finally Jill but Jill acts more mature than her age. So tad since he is the oldest and smart he helps his parents kill is also older than the rest and has anger issues. Jill is the youngest and only girl in the family so she gets decent amount of attention from her parents while will is extroverted(your social bar is filler by being around people but you don't have to be super social and out going to be a extrovert. Think of having 0 coins but when you socialize with people you gain coins while being a introvert you start will coins and lose them when you socialize. Will still has a less outgoing, awkward personality.) So his parents pay him attention cause they don't want him to be depressed cause his social bar(happy bar?) Is empty but they don't want him to also interact awhole lot and have a panic attack. For bill he doesn't get that much attention though cause he isn't the oldest(most mature) and he doesn't have any problems (everybody doesn't think he does but he just hides it) Bill is attention starved and when he gets a tastes of being in charged maybe he formed a group or took over a small world so this leads to him forming a plan and attempting the take over of his world but during the process he destroys it. Since this was an accident and didn't mean it to turn out the way he fled and decided to act like he did it on purpose and take over other dimensions/worlds and form friends/allies. After multiple times taking over worlds successfully he lost most of his sanity and tried taking over dippers world(in this au Bill did meet Ford and Ford still hates bill but not as much cause he knew bill just lacked a parental figure and was attention starved. Basically Ford saw bill as maybe his own kid or something similar to that even though bill is still old at least in human years in demon years he is around teenage/young adult age) most suff that happened in the show happened in this au. So that means weirdmeggadon(is that how you spell it?) Happened and bill got kinda killed. His magic got really low so he stayed in axolotl's dimension until he got his memory back, a good bit of his power and woke up(?) He lost so much magic he didn't have a conscious. After he left he visited a place that was just a void that barely anybody went to so he could regain more magic. Finally he started making deals to regain even more magic and during him regaining magic he got bigger closer to his original size.(he was about the size of a ant when he was in axolotl's dimension. After a few thousand years(unless whoever is reading wants some billdip then I guess it could be a lot shorter or imr being different where he is) Then bill comes into contact with his family(parents died) obviously the family won't be very happy to see bill..The family heard of bills journey and maybe saw a few glimpses of him. While bill lost a lot of his magic and consciousness and had to remake one( restart his brain but still with his memories?) He got back most of his sanity so he felt a lot of guilt and sadness for destroying his dimension and killing his parents and other demons. But he still had his memories and was upset, angry, confused, and disappointed for having theses emotions. He then tries to fight but quickly realizes he is to weak and tries to flee but got knocked out or got captured and gave up for the time being and went into his mind/dreamscape. He then woke up or came to when he was placed in a demon cage. The film film start asking him questions and yelling at him. Stuff happen and then they start forming a relationship that is stronger than their old relationship since they never interacted with Bill. Oh also two last things they apologize for ignoring him and it's up to you if you want to imagine them as a human or shape firm. I'm imagining them as both shape
