Basically same world as walking dead Set in gravity falls.15 old Dipper and 18 old Bill.
With Bill
The sun is rising marking a new day ,but time is no longer an issue in the world of the walking dead where it's either kill or be killed by walkers or even humans. In a mansion on top of a hill a pair of golden eyes slowly open causing the man to groan as he gets up from and stretches.
"Boy oh boy Bill what wonders will this day give." 'The man 'Bill' said sarcastically looks at his fireplace and no wood left "Of course..." Bill mumbled putting on his jeans, snow boots and matching jacket since it is winter. Bill brushes his blonde hair back with his fingers frustrated "One day when this is over I'll lead the survivors as their king!" Bill smirked as he heads out taking his axe with for wood chomping ,and a knife and gun for protecting against threats.
With Dipper
A girl named Dipper is with her group walking toward the town of gravity falls where her grunkles believe could be safe. Group consisted of Dipper, Mabel, Wendy, Soos, Grunkle Stan and Ford.
"Hey Dipstick!" Dipper's twin sister Mabel said looking in her backpack or as she calls it the 'sweaterback' "I think I need more yawn to make more sweaters think we can go look for some?" She asked.
"No way!" Stan said being the leader and when the team faces other people he's the first to know if their good or bad people ,so naturally he's leader along with his twin Ford the tech genius who grumbles in agreement "We more more important things than sweaters.. no offense pumpkin."
"Well uh!" Mabel started but couldn't finish ,but being on the 'warm clothes captain' she had a duty to give warmth! "Huh duty." Mabel giggled making Wendy and Soos do so too.
"Grunkle Stan I understand food, water, weapons, transportation, and a new home is more important than staying warm ,but it's still important."Dipper said pulling out a map she stole from a nearby store.
"You said it! Fight the man!" Wendy cheered punching her arm making her blush.
"Yeah even though he's technically your great-uncle ,and that the government completely shut down because of the dead killing the living causing the human race to go back into cavemen times ,so there really is no 'the man' anymore dude." Soos said nonchalantly then gives her a hug. Even though the group ration food and walk everywhere he's still a big guy.
"Anyway... If it makes you girls happy than how about we split up."Ford said looking at Dipper's map pointing at an area and takes his compass "Stanley can go with Dipper and Wendy to check for supplies in this mansion from here it looks to be in good shape and I'll go with Soos and Mabel to the mall it should have something left!" Ford said.
"Alright ,but take the walkie talkie." Stan said giving one to his twin brother, then looks at his team mischievously "The rich people might have left something valuable ,so that when I die I'll leave back a fortune!"
"You old son of a gun!" Wendy said proudly to Stan then fist bumping Dipper who blushes.
"Bye sister! Remember me every time you look in a mirror!" Mabel said hugging the life out of Dipper chuckling "Get it! Because were twins!"
"Oh man hambone I just got that joke!" Soos laughed holding his gut which attracts a walker ,but he skillfully dodges, trips and stabs the creature clean "And this is why I'm considered a valuable member despite lacking the mental or physical uh stuff. Thank you hours of zombie movies and video games." Soos said punching the air making a weird pose.
With Bill in the woods
'Okay let's see... Fence stakes only got two walkers today and the surrounding area seems empty ,so the cold must be affecting the Bitters movements' Bill thought as he continued to chop down a 6ft pinetree until it fell ,so Bill places it gently on wagon full of wood "Mom, Dad, and Jill would've wanted a tree..." Bill trailed off ,but shook it off so he could walk up hill toward his home. She
"AAAAAHHHHHH!!!!" Dipper screamed as she and her grunkle and friend we're being attacked by a German Shepherd on a chain and it appears Dipper has an injured leg.
"PYRONICA HEAL!" Bill yelled causing the dog 'Pyronica' to stop and the group to stare at Bill in wonder "Hello I'm Bill Cipher sorry about that folks she's just a really good guard dog." Bill apologized pulling his wagon into the mansion ,but stopped to look at Dipper and smirked "Hey Doll want to spend the night since it seems you've obviously tripped on something and are injured"
"On a Pinetree ,but that doesn't matter yah creep!" Dipper said with sass causing him to chuckle. Pyronica gets into stance right as a gun cocks nears Bill's head.She
"What's your purpose!?" Ford yelled with Soos and Mabel who even has more yarn backs him up with a blade and a grappling hook.
"Right now to invite you oh so lovely people into my home that has been in my family for generations for I am alone and I have the supplies that'll last you quite awhile and that its gonna storm soon so you might wanna get in." Bill said surprisingly cooly sending the group into shock at the situation and how he's handling it.Ford nods letting his guard down.
"Fine ,but if it doesn't have at least 5 out of 10 Mabel stars then were out of here!" Mabel said with sass even giving a snap of the fingers and giving the 'look'.
Later
"This place has 15 out of 10 Mabel stars who knew!" Mabel cheered drinking hot chocolate and sitting near the fire with her group and new maybe friend.
"Well I'm glad it's to your liking ,but how about introductions?" Bill said passing out potato chips to the uncertain group no knowing whether to give out names or not "I mean unless you want me to just call you all Shooting Star, Fez, Six Fingers, Red, Question Mark, and Pinetree?" He pointed at each person with each nickname.
"Why am I Pinetree?" Dipper asked from the couch since her leg needs bed rest. Bill smiles and walks up to her kissing her hand making her retrack her hand and blush.
"Because I met you when I came home with a Pinetree for christmas and because you tripped on a tree." Bill teased staring at her face making her do the same until Stan pulled Bill away from the couch.
"Anyway, I'm Stanley, my brothers Stanford, The lumberjack is Wendy, Big guy is Soos, My Great Nieces! Are Mabel and Dipper!" Stan said making his point clear.
"Well nice to meet you all how about I show you all your rooms." Bill said petting Pyronica's head.
"Just no funny business mister I've got an axe and I know how to use it!" Wendy threatened twirling her axe around pointing it at him ,but he calmly lowers it.
"Hey uh dude is it okay I stay here?" Soos asked looking around nervously making Bill raise an eyebrow "It's just I'm usually watch-out at night since the Stans are old, pines dudettes need sleep to grow, and Wendy said no."
"Me and Stan will sleep on the couches." Ford said he and Stan about ready to pass out. Then they do snoring loudly.
"Its because their old!" Mabel whisper-yells at Bill making him chuckle ,but then Mable gasps looking at Dipper and Wendy excitedly "This means we girls can have a sleepover!" She squealed.
"Uh about that Mabel." Wendy said looking away "I was hoping to get some sleep on a nice comfy bed and sleep till noon again ,so I think I'll pass on any sleepovers."
"Me too Mabel." Dipper said try to get up "I need to rest for my leg to heal." Mabel nods in understanding.
"Here." Bill said giving Dipper a cane "It's my grandfathers it'll help." Dipper smiles thankfully "Come with me." Mabel, Wendy, and Dipper follow Bill upstairs where he points at the three rooms "You girls came decide who takes what room and the bathroom is down the hall." Wendy and Mabel quickly snatch a room and and springs can be heard.
"Uh Bill?" Dipper said awkwardly "I'm used to sleeping in a room with someone else can I sleep in yours? Asumingthebedisbigenoughimean!" She said quickly blushing hard making Bill do the same ,but silently helps her to his room where the master bed is.
"It's big enough for three I know from experience." Bill smirks then points at the bathroom next to Dipper "Master bathroom is right there and if you need to change go ahead." Bill is already taking off his coat and pants revealing a yellow shirt and black night pants and what Diper can assume is many tattoos on his arm and back "I know I'm impressive but staring really Pinetree?"
"Shut up!" Dipper snapped removing her clothes showing a plain grey shirt and shorts. Dipper wobbles on the bed as Bill is on the other both staring away until Dipper break the silence "Bill i'm cold." Bill smirks coming closer to spoon her making both much warmer and happier than ever even in the cold of the winter in the zombie Apocalypse.
