The armies collided and madness ensued. Williams were being destroyed left and right, the Yo Kai were surprisingly holding their ground. Mabel blasted through a few with her grappling hook, Dipper punched any ones he could reach in the eye.

"Alright guys let's keep it together! Watch out for Tim! His weakness is hats... apparently!" Nate coached.Tim laughed and a bunch of Williams grew to a giant size, axes appeared in their hands.

"Hovernyan use your M Skill!" Katie shouted, after a moment Hovernyan sped forward and punched through all three of them, obliterating the Williams.

Nate, Dipper, Mabel, Whisper, and Katie shoved through the chaos and ran down a hallway leading into the main room of the castle.

"Alright so the plan is to find Bill and then get that Zodiac formed." Dipper said, as if on cue Bill crashed through a wall and landed next to them.

"You'll pay for that Will! Oh hi guys." Bill waved.

"Bill we have to get going! We need your for the Zodiac!" Nate said.

"Well I'm kind-of fighting Will." A fireball barreled towards them, Bill created a shield and blocked the fireball.

"We can hold him off, you just have to come with us!" Nate insisted.

"Guys here he comes!" Katie warned, Will stormed into the room.

"Stay away!" Mabel shouted.

"Wonderful, you all are ripe for the killing!"

"Take this!" Whisper threw a vial with blue liquid in it at Will, the liquid landed in his eye.

"Ow what the heck was that!? Why does it burn so much!" Will's eye turned into stone. "My eye! Are you serious?! A rebellion and a missing eye!"

"That was Rock On Unstract! The name isn't that good but it works!" Whisper grinned.

"Now let's go!" Nate said, they all ran back into the battle. For the most part the Yo Kai were winning, attacks were being thrown around and Tim was desperately trying to escape Wazzat. Without any direction the Williams were easily being wiped out.

"Alright everyone! Let's finish this!" Nate yelled.

A Zodiac had already been prepared for them and the Yo Kai were all waiting.

"Lyet's finish thyis! I wyant more Choco Bars!" Jibanyan said.

"Indeed. It is time to conclude all the suffering we have endured." Shogunyan said. Everyone got into position and held hands, the Zodiac began to glow brightly. Will burst into the room, he roared with rage. Will's eye had returned to normal.

"I WILL DESTROY YOU!" Time suddenly froze around everyone except for those of the Zodiac.

"Oh no." Nate muttered as Will approached, they broke hands and got ready to fight.

"Alright kids, I'm done making deals. None of you have anything I want, except for your corpses!" Will cackled manically.

"Yeah wyell I'm already dyead! Wyait then what'll hyappen?" Jibanyan wondered.

Bill teleported behind Will and punched him forward, Shogunyan leaped into the air and drove his sword into Will's eye, piercing it. Then he removed the sword and cut Will in half.

"Time still isn't unfreezing." Mabel said.

"Hang on there has to be some information." Dipper flipped open the journals, when he reached the second one he noticed a code and cracked it quickly. "Alright looks like Bill leaked some information. 'Time slowing is easy to do, breaking it happens when we break.'"

"When did I reveal that? Man how much punch did I have?" Bill wondered.

"So we just have to keep attacking him." Katie said. Jibanyan, Kyubi, Shogunyan, and the other Yo Kai fired off more attacks at Will.

"EID LLAHS OUY!" Will screamed, a bit of his eye escaped the wrath and began reforming Will. Dipper took a flashlight he had with him and threw it at the eye piece and knocked it back into the fighting.

A giant green bubbled appeared around Will, preventing the Yo Kai from stopping Will to form. Mabel charged at it and blew attack glitter at the bubble, somehow this glitter went through the bubble and once again prevented Will from reforming.

"Gah! I thought no attack could be so weak yet so strong!" Will shouted.

"How did it get through the bubble?" Nate wondered.

"Will didn't see it as worth blocking." Bill answered.

"Let's finish this, ready Katie?" Nate asked her. Time was starting to unfreeze.

"Right." Katie nodded.

"We call on the power of all Yo Kai! Give us your assistance in bringing down the monster Will Cipher! Let's do this together, all of us!" Katie and Nate shouted in unison, their watches began to glow and they held them next to each other, a bright beam erupted from the watches and slammed into Will. Time unfroze and everyone got in position, holding hands.

The Zodiac's center exploded in a white light, Will reformed and was dragged into the beacon.

"NO! NOOO! I WILL NOT LOSE! YOU THINK YOU'VE WON!? WELL I'LL BE BACK! YOU'LL SEE! YOU'LL ALL SEE! AXOL-" Will was pulled into the beacon, a shockwave shook the Earth, the castle vanished along with all the Williams and everyone was returned to Gravity Falls.

"So it's over?" Nate looked up.

"Will didn't even get to invoke the ancient powers, he's gone for good." Bill said.

"YEEHAW! This is better than a million swirls of ice cream!" Komason cheered.

"It appears as though all damage is reversed, and hopefully everyone outside of Gravity Falls will have forgotten about this." Ford said.

"If not I'll make sure they do, one less event to be scarred for life by." Bill said.

"So that's two times we've saved the world. World you owe us." Mabel said.

"Did time go by as well, I better not have missed any summer break." Dipper chuckled.

"Well done Nate. You and your friends are quite the group." Venoct said.

"Venoct! Man I'm glad you're alright."

"Indeed. I am glad you're still alive as well Nate. I prefer my friends alive."

"So Venoct about the stone..." Nate looked down at the Reality Stone.

"Oh keep it! I have plenty, plus you need it more." Venoct said.

"Really? Thanks Venoct! One more thing, where did you get this?"

"Being friends with King Edma has its benefits." Venoct winked.

"So Nate you can visit any time right?" Katie asked.

Nate nodded. "But it'd be better if we did it when your world's Nate isn't around."

Katie laughed. "True."

"I'm so glad everything worked out! Just one thing, Nate your parents are going to notice you're missing soon." Whisper spoke up.

"I guess we should get going." Nate sighed.

"Well you can always visit." Mabel reminded him.

"Be sure to tell us all about your adventures with Yo Kai!" Dipper added.

"And if you need help feel free to call me, Komason's letting me move in." Bill informed them.

"I will take the lady back to her home." Venoct offered.

"Alright, thanks Venoct. See ya Nate!" Katie waved.

"Alright Reality Stone. Activate and change the place!" The stone glowed and the two warped away.

"See Nate, that's how you do it." Whisper said.

"Oh come on that was barely a rhyme!" Nate countered.

"Nya I cyan't wait to get byack to my precious Choco Bars." Jibanyan yawned.

"You and those Choco Bars." Whisper sighed.

"Well he is a cat, gotta enjoy eating something." Nate reminded Whisper.

"I enjoy eating everything! Except vyegtables! They're gross!" Jibanyan said. Mirapo walked up to them, ready to take them home. The Yo Kai all began leaving as well.

"Bye everyone! Stay safe! If you need help you know where to find us!" With that Nate jumped into the portal, Whisper and Jibanyan behind him.

And with that this story comes to a close. I really have enjoyed writing this story, it was fun to do a new take on my first story. I changed a lot more than I originally anticipated, made it much longer, and overall a much more interesting and cohesive story. I think if you tried comparing the differences you'd have way to long of a list, instead try comparing the similarities. Since I think there's less of them than differences.

Leave your thoughts on the story in the comments, as well as what your favorite part of the story and questions you may have if something wasn't entirely clear. I hope you enjoyed this story, because I sure have. Have a nice day!
