Bill was sitting in a throne on his gigantic castle which had been located on Jupiter.

"Man I had it all wrong taking over Earth! Jupiter is where it's at! That giant hurricane is so fun to spin around on! Plus it's so big I can blow up whatever I want! And now that I'm free from that stupid Gravity Falls prison I can do whatever I want, just gotta wait for the right moment to strike down Will."

Suddenly one of the walls of his castle was blown to pieces and Tim and about 10,000 Williams stood at the entrance.

"Surrender now and Will won't, and I quote, 'make you life so miserable you'll wish you were still a rock.'" Tim said.

"I'll have to check my calendar. Here let me see here." A calendar appeared in front of Bill. "Nope I'm all booked. Sorry maybe I can squeeze you in next year."

Tim shrugged. "Well I guess you're busy then-wait! Will warned me of this, you're trying to trick me!"

"Wow. I wonder how you came to this shocking conclusion." Bill said sarcastically. "You must be a detective, here's a prize." A giant pile of deer teeth buried Tim.

"Yes he's gone!" One of the Williams cheered. "Now we can actually fight! CHARGE!" The Williams surged forward.

"Oh boy some action. This'll be fun!" Bill rubbed his hands together. "But I don't want to destroy my castle. Let's take this somewhere else." Bill clapped his hands and the army was transported to a random area in Jupiter along with Bill.

"I'll rip you to shreds!" One of the Williams jumped at Bill. If looks could kill the one Bill gave would, and it did. The William crumbled to purple dust. "Time for some art." Bill flew into the air and began making a drawing of himself right in the center of the army of charging Williams by using a laser to melt them. After he was done he somehow blew the smoke from his finger away.

The Williams were now firing weak lasers at Bill but he gracefully evaded them all with some impressive body distortion. Next Bill got a giant bottomless container of gasoline, and dumped it all over the Williams. He then lit a small match and dropped it on the William army. They quickly all began burning to death and Bill laughed hysterically as it happened. "It is good to be back!"

Then Jupiter exploded.

As Bill floated through space he got redder and redder. "OF ALL THE CRUEL TRICKS! THE FOUL JOKES! THIS CROSSES THE LINE! I'M STOPPING WILL! EVEN IF IT MEANS JOINING THOSE PATHETIC MEAT SACKS! LOOK OUT WORLD, BECAUSE BILL'S A HERO NOW!" Bill warped off to Gravity Falls.

When the light died down Nate, Mabel, Whisper, Dipper, and Katie had arrived at Gravity Falls. The Yo Kai were still recovering from injuries and trying to account for the losses. A report from Sgt. Burly said that they only had around 75 Yo Kai left.

"This isn't good." Nate sighed.

"Well look on the bright side Nate. With Katie here we now only need one more to be able to defeat Will once and for all!" Whisper reminded Nate.

"About that... We figured out who the last symbol represented. It's Bill." Mabel said.

"You mean the same Bill who tried to murder you guys?" Nate asked, feeling hopeless. Dipper nodded grimly.

"So could I get a recap of what's going on and why you guys need me?" Katie requested.

"Oh right! I'll catch you up and give you a tour." Nate offered, Katie nodded thanking him. Then they walked off and Nate began to tell Katie about what had happened leading up to that point.

"I don't get why Will hasn't attacked yet. If he has Ford hostage he can just get the information." Whisper said.

"Well Will can only do that if Ford makes a deal with him, and since we're safe Ford has no reason to make a deal." Mabel explained.

"Plus he could be busy trying to track down Bill." Dipper added.

"Then it appears we have a race. Who can find Bill first."

"Except Bill would never join us, only kill us..."

"And Will has the ability to search the galaxy with ease while we're probably dead the moment we leave Gravity Falls."

"And while this is happening that girl decides to steal away Nate!" Mabel yelled.

"What do you mean? Nate offered to show her around and they are very good friends." Whisper said.

"Mabel's just jealous because Nate is her crush of the week." Dipper said.

Mabel blushed. "He is not!"

"He totally is." Dipper said.

"You're totally a dork." Mabel said and she blew a raspberry at him.

"You're just jealous because I can actually keep my focus." Dipper said.

"Like you did during that road trip or that spring dance?"

"Ok I took Stan's advice that first time and I've learned my lesson to never do that again! And I thought that was just what you did during a dance, hop around to one girl and the next!"

"You got that from watching Middle sCool Dance!"

Dipper was caught off guard. "I-I have no idea what you're talking about!

Whisper sighed. "It's like Nate and Jibanyan all over again."

Nate and Katie walked back to the Mystery Shack once Nate concluded his tour.

"You know it's really nice knowing someone who pretty much has the same experiences as I do." Nate said.

Katie nodded. "Definitely. Having only Whisper and Jibanyan to talk to about Yo Kai can be exhausting."

"They're always arguing over something." Nate agreed.

"Nate you told me that Bill was Will's brother right? And he was an enemy of us. So how are we ever going to get him on our side. I'm worried he might betray us or Will could find a way to attack us." Katie said.

Nate sighed. "I'm not really sure, but I do know this: No matter what we can't give up. I've-we've been through enough to know that there's always another way. Either cherry blossoms or sending out grandparents to beat up old time traveling ladies. It doesn't always have to be the conventional way."

Katie smiled faintly. "Wow that was really inspiring. Keep that one for the final battle."

"Or I could start writing a new speech." Nate joked.

"Only if I get to work on special effects for your performance." Katie added, now clearly trying to hold in laughter.

"Just don't hire Whisper to book the venue, or he'll get us a table in a food court and tell us it's a concert hall." Nate and Katie both began laughing, just laughing even at a not-so-funny joke felt great for the two.

Later that day everyone was gathered outside the Mystery Shack trying to figure out if any of Ford's inventions could track Bill, then from what seemed to be fate itself, Bill appeared in front of them.

"Hello Gravity Falls!"

"BILL!" Mabel shouted. Nate stood up and got ready to summon a Yo Kai.

Bill put his hands up. "Whoa whoa whoa. No need to get hasty kids. I'm not here to fight, if I was you'd all be dead. I'm here to talk. I have my brother just as much as the next person, so I'm here to help you kids. Because, drumroll..." A drum set appeared behind him and began playing a drumroll. "Draw it out... Big reveal..."

"We know you're the triangle in the Zodiac!" Nate shouted.

"Dang it! I thought it was a way bigger twist than that!" Bill snapped his fingers and the drums vanished.

"So you want to join us in defeating Will?" Dipper asked, Bill nodded. "What's the catch?"

"Well you give me the universe without trying to stop me!"

"Yeah not happening." Dipper said.

"No way we'd just give you the universe!" Mabel glared.

"What if we give him one of the other universes?" Katie suggested.

"Well then they'd have to deal with him. And we can't dump our problems on another world." Nate said.

"How about we try negotiating the deal?" Whisper recommended.

"No way. It's all or nothing." Bill said.

"Then give us until tomorrow to decide at least." Nate said.

"Fine with me. I can wait. It's your heads on the chopping block if Will attacks." Bill said and he warped off.

"We need to hold a council or something." Nate said.

"Can we do it tomorrow?" Dipper asked.

"Yeah I'm so exhausted! We've done so much today!" Mabel added and yawned.

"Yeah, sleep sounds nice." Nate agreed, finally realizing how tired he was.

They all decided to make the final deal tomorrow and went off to sleep.

Bill was sitting outside at nighttime staring at the stars. "To think. One day they'll all explode!" Bill laughed at the thought. "It's fun to think of the deal I gave those kids. Now they'll have to give me the world if they hope to win. Forget being good, being manipulative is way better!"

"I dunno sir, being good is mighty fine." Komason said, walking up to him. Bill turned to the Yo Kai.

"What do you know? Have you tried being evil?" Bill asked.

"Well no sir. But that's because being good is so great I don't even want to think about being the opposite of it."

"Well if I became good that'd ruin everything, I'd be the laughing stock across the multiverse for villains and good guys would never accept me because of what I've done."

"Sir I know it wouldn't be all rainbows and sunshine but if you gave them time and you worked hard to change, doing good things, then they'll shine bright and show you've moved past those bad things. They'll always be there, but you can use them to prove that you've changed and became stronger. Life isn't always a patch of ice cream swirls, but it sure is mighty fine when you try to be good."

"You really think that?"

"Well sir, there's only one way of knowing. And that's to give it a chance." Komason nodded.

"Thanks kid...What did you say your name was?" Bill asked

"I'm Komason. Pleasure to meet you."

"I'm Bill. Bill Cipher."

I'm so sorry about the long wait for this chapter but hopefully it was worth it. Those was one of my favorite story arcs in the original and the only good thing about the story that I could see. The interaction has been changed a lot but I kept the basic idea and the same outcome. I hope you enjoyed this chapter and have a nice day!
