Chapter 9

Back at the clock tower, Doc had a lot on his hands, aside from keeping the DeLorean discovered by the town residents. Heartless soldiers seemed to have tried to tamper with the experiment to send Marty, Sora, and Co. back to 1985. Luckily, Doc had his gun by his side.

"Get away from the wires!" he shouted to one near the lampposts and shot it.

Then one jumped on his shoulder. "Argh! Get off! I'll never submit to the darkness!" he growled, hitting the Heartless in the head with the butt of his gun, destroying it.

He then looked up to see a knight-looking Heartless near the pole to attract the lightning. "YOU! GET DOWN FROM THERE!" he shouted, shooting the Heartless, which fell onto the clock tower's stairs, disappearing. "Bullseye!" exclaimed Doc, triumphantly.

Just then, Sora arrived with Goofy and Riku on his glider, and Mickey pulled up with Donald and Kairi on his. They hopped off towards the Doc.

"There you guys are!" exclaimed the Doc.

"We heard gunshots and I sensed the Darkness." said Riku.

"Gosh, is everything alright?" asked a worried Mickey.

"Just a few Heartless pests, but nothing I couldn't handle." replied Doc, waving it off. He then realized they were one hero short. "Great Scott! Where's Marty?" he asked.

Before anyone could reply, Doc's car pulled up, and Marty came out quickly, out of his suit and back in his shirts, jacket, life-vest jacket, jeans, suspenders, socks, watch, and sneakers.

"Sorry I'm late, but I wasn't gonna go back in that zoot-suit." he told Doc.

"Plus, most of his clothes and that watch don't belong in the 50's." added Sora.

"But good news: We did it! My parents are together and my family's saved!" exclaimed Marty.

"It's true, George came through and knocked out Biff in one punch… before we had to deal with his Heartless… luckily he's ok, but won't be hurting anyone for a while." added Mickey as Marty showed Doc the picture.

"He's never stood up to that butthead in his life!" exclaimed Marty.

"Never?!" asked Doc, a little concerned, handing Marty back his picture.

"Is something wrong?" asked Riku.

"Un, no, nothing at all." replied Doc as they walked over to the DeLorean. "Alright, all of Marty's stuff and my 1985 counterpart's stuff are in the car, electric pole is hanging on the side, (looks up to the dark, cloudy sky) and weather's on schedule." remarked Doc.

He then grabbed a clock. "Now then, after calculations in timing and weather resistance, in precisely 32 minutes and… (looks at his watch) 14 seconds, this clock will go off. By that time, the time machine will be at the starting point, and it'll be your job to hit the gas pedal to bring that sucker up to 88 miles per hour, and then lightning strikes and the electricity will go through the poll, generating the 1.21 jigawatts, and you all will be sent back to 1985, at the precise time you left, like nothing ever happened." he told them, setting the clock near the dashboard and closing the door.

"Sounds simple enough." remarked Kairi.

Everyone laughed at that remark.

"It's hard to believe it'll be 30 years before I see you all again." sighed Doc.

"We will have a lot to talk about after spending a week in 1955." agreed Riku.

"Guess so." replied Doc.

Suddenly, while others were about to get into the car, Doc reached into his jacket pocket… and pulled out their letter to him. "What is the meaning of this?!" he asked Marty, Sora, and Co.

Sora, Riku, Kairi, Mickey, Donald, and Goofy gasped when they realized Doc had the letter.

"You'll find out in 30 years." was all Marty could say.

"It's information about the future, isn't it!?" exclaimed Doc, frantically.

"Doc wait!" cried Sora as he and others ran towards him on the other side of the time machine.

"I told you! The consequences could endanger us!" cried Doc.

"Doc please!" cried Goofy

"You have to trust us!" pleaded Donald.

"It could damage our future! King Mickey, how could you let this happen?! You know the order is against meddling! You all could be in serious trouble for telling someone their future in this world!" exclaimed Doc.

Mickey knew Doc was right, but even as a king, he didn't care this time. "Doc, I'm really sorry, but it's a risk you're gonna have to take! Your LIFE depends on it" said Mickey, trying hard not to cry as well as the rest of the heroes.

"NO! I refuse to accept the responsibilities!" cried Doc, tearing up the letter, much to the other seven's horror.

"Doc, NO!" cried Kairi.

"Then I guess we'll just have to tell you!" cried Sora.

But before anyone could tell Doc his fate, Goofy gasped and pointed farther down the street near the clock tower.

"Fellers, look!" the dog cried.

The others turned to see… a member of Organization XIII!

"Great Scott! Who is that?!" asked Doc, unwittingly putting the torn letter pieces into his jacket pocket.

"Organization XIII!" cried Mickey.

The member leaped forward, and stopped 3 feet in front of the eight. It then snapped its fingers, and suddenly a tree branch fell onto the chords connected from the wire across the lampposts to the rod on the tower, disconnecting them!

"Great Scott! He disconnected the wires!" cried Doc.

The member then removed his hood to reveal a familiar man with long grey spikey hair.

Sora, Riku, Kairi, Mickey, Donald, and Goofy gasped in horror as they knew the man all too well.

"Xemnas!" exclaimed Sora.

"Xemnas? As in the leader of the old organization and a current one in Master Xehanort's?" asked Marty.

"The very same." growled Riku as he and the other travellers glared at Terra Xehanort's Nobody.

"Nice of you to remember me." sneered Xemnas, sarcastically. He then grinned evilly, making Donald, Goofy, Marty, and Doc feel uneasy. "I also see you lot have been… meddling." he added.

"What gives you that idea?!" growled Goofy.

Xemnas chuckled. "You're are truly as dumb as you are ignorant. You revealed the idea of other worlds to Marty McFly and Dr. Brown, you unwittingly let the boy interfere with his parent's first meeting, and right now, you're warning the crazy scientist of his fate." he replied.

"I'd hardly call that meddling. They got the parents back together." scoffed Doc.

Xemnas' grin darkened. "Even so, they revealed the secret of world-travelling. They aren't even fit to return home, or to their worlds."

"Who cares?! We trust Marty and Doc, and they trust us!" protested Sora.

"Besides, they swore to the secrecy of helping protect the order. Unlike you and the other bad guys." added Riku, glaring.

"What are you even doing her you monster?" asked Kairi, angrily.

Xemnas glared at the eight. "If you must know, Maleficent sent me here to make sure none of you return."

Flashback:

Maleficent had just sent Pete to get a member to stop the world-travellers from returning to 1985. Pete ran into the throne room where he finds Ansem, Xemnas, and Young Xehanort sitting in their chairs.

"Uh, excuse me?" asked Pete.

Young Xehanort sighed. "What do you want, now?" he asked the cat, annoyed.

"It seems as though the punks are about to get back to 1985 with the McFly boy. Uh, Maleficent has requested one of you go stop them." replied Pete, a little worried.

"Hmm. Seems as though the Heartless Biff Tannen has failed to dispose of them." mused Ansem. He turned to Xemnas. "I would go myself, but I am needed to check on the weapons created by that old woman and that soldier who wants to find the heart of something."

Xemnas nodded in understanding. "I will go then. I'll see to it that they DON'T return."

He then hopped off his chair and opened a Corridor to Darkness.

"Are ya sure you don't want me to give you some back-up?" asked Pete, hopefully.

His response was Xemnas flicking him in the forehead and sending him to the ground, the same way Hades did to Sora back at Olympus Coliseum. "No, you will go check on Scar and his army, and then clean the library." Xemnas scowled as he left, the corridor vanishing behind him.

Just then, Vanitas entered the room followed by Luxord and Larxene, the latter two heading towards their chairs. He looked at the knocked over Pete and snickered.

"That's what you get for being the fat weakling." he snickered.

Ansem and Young Xehanort could only nod in agreement.

Back to Hill Valley:

"And now that I'm here, none of you are going back." he said, evilly.

"Not gonna happen." Marty disagreed. "These guys are some of the greatest friends I know. They helped me get my parents together to save me, Dave, and Linda. They know how to fight those Heartless things well. They have every right to go back to the future with me so they can protect the other worlds from the likes of YOU!"

Xemnas only smirked. "Such a bold disagreement. Too bad it'll be your last."

"Oh, I wasn't trying to just argue." replied Marty. Xemnas raised an eyebrow in confusion. "I was also causing a distraction." Marty added, smirking.

Before Xemnas could reply, out of nowhere, Doc suddenly punched him in the face, sending the Nobody to the ground, grabbing his face.

"Nice job Doc!" cried Kairi.

"Thank you! Now then, (grabs the fallen cables) get that man out of here, and then get the DeLorean in position!" he called as he ran inside the clock tower.

"With pleasure!" replied Sora, summoning Kingdom Key.

Riku then summoned Way to Dawn, Mickey summoned Star Seeker, Kairi summoned Destiny's Embrace, Goofy summoned his shield, and Donald summoned his staff, then summoned Marty's skateboard, and tossed it to the teen.

(Xemnas Final Battle from Kingdom Hearts 2 plays)

Xemnas got up and scowled as then the floated to the center in front of the clock tower. The heroes ran up to face him, weapons ready, just as a magical barrier surrounded the eight in the grassy area, separating them from Doc, the tower, and the DeLorean.

"You will never defeat me." snarled Xemnas, summoning his Etheral Blades.

Mission: Defeat Xemnas before time runs out to get back to the time machine.

Party Members:

Sora

Donald Duck

Goofy

Riku

King Mickey

Kairi

Marty

The battle commenced. Sora and Riku used their blades in a sword fight against Xemnas' blades, only to get knocked away after the three received a few scratched while the teens received bruises on their shoulders.

Donald used Thunda on Xemnas, but missed. He then casted a Blizzard spell to hold him in place, only to watch as he used his blades to free himself. Donald tried to use a fire spell against the former superior, only to be reflected and ended setting his tail feathers on fire. Donald then began to run around in a panic.

After Mickey casted a cure on his buddies, he dodged Xemnas tossing his blades, only to get hit in the arms and legs when they returned to Xemnas in the process. Mickey got up and shot beams from Star Seeker, only to cause minor damages to Xemnas.

Kairi and a cured Sora then tried to do a double-strike, striking Xemnas in his arms. The grey-haired scowled as he sent two of his blades to strike down the two. They almost hit them, but Riku tossed his keyblade and the beams were pushed away. Riku then quickly summoned Soul Eater and then, teamed up with Sora and Kairi to attack Xemnas. They combined their blades, to create a beam that managed to blast Xemnas.

This made Xemnas furious, he tried to strike again, but Marty rode by on his skateboard, and Goofy rode by, struggling but managed to balance on his shield and both punched the Nobody in his face, causing him to fall to the ground. Goofy and Marty reunited with the other five.

Xemnas got up and began to go into transform, laughing evilly. In a bright flash, he appeared in his monster form. Sora and Co. had shocked looks on their faces.

"Holy cow!" exclaimed Mickey.

"Now how do we beat him?!" cried Kairi.

Marty turned to Sora. "Think it's time to use your best form yet!"

Sora nodded, and then in a flash of light, he appeared in his white Final Form. He was also floating, hair and glowing white clothes flowing in the wind, with the Keyblades Circle of Life and Devine Rose floating behind him. He charged towards Xemnas, unleashing Final Strike on the monster three times, defeating it.

Xemnas soon returned to normal. He glanced up at the seven heroes who glared at him. "You've won this round, but mark my words, you WILL perish when you least expect it." he said, darkly as he disappeared through a Corridor of Darkness.

Sora soon landed, keyblades disappearing, yet still in Final Form, clothes not glowing.

"Nice work everyone!" congratulated Mickey as he and the others dismissed their weapons.

"That's totally my favourite form!" complimented Marty.

"Mine too, makes you look tough." giggled Kairi.

Sora blushed as he rubbed the back of his head. "Thanks guys." he replied.

Suddenly, the barrier disappeared and the others looked at the clock tower, and gasped. There in front of the clock, was Doc standing on the thin ledge.

"Doc!" cried Marty as he and the others ran towards the tower.

"Doc, we have to tell you about the future!" called Sora.

"What?!" called Doc as he struggled to get across.

"He said that we have to tell you about the future!" answered Riku.

"On the night we go back, YOU ARE…!" began Mickey, only to be interrupted by a boom of thunder.

Doc noticed that the wind was getting stronger and called below, "Everyone! The time machine! You've only got 5 minutes!"

Realizing they didn't have enough time to warn him, Sora, Riku, Kairi, Mickey, Donald, Goofy, and Marty ran to the DeLorean. Marty sat in the driver's seat, Donald and Mickey in the front passenger seat, and Riku, Sora, Kairi, and Goofy in the back.

KH

They soon drove to the starting point, getting the DeLorean in position. Marty, Riku, and Goofy stepped out to get the electric hook into place. Once that was done, they got back inside.

"Poll is set." Riku told them.

"That's good. Now we wait for the clock." said Kairi.

But Marty wasn't satisfied. "Darn it Doc, why did you have to rip up that letter?" he groaned.

"Oh, he's too stubborn." said Goofy. "Gawrsh, if only we had more time."

"Hey! We got all the time we want! We're in a time machine for crying out loud!" exclaimed Sora.

"Yeah, we'll just go back earlier before we left to warn Doc about the Libyans!" agreed Mickey.

"Alright, about 10 minutes oughta do it." said Marty, changing the destination time from 1:35 a.m. to 1:24 a.m. He started the engine, but it wouldn't rev properly.

"No… no, no, no, not now!" exclaimed Marty, frantically turning the keys.

"Not good." muttered Riku.

KH

Meanwhile up on the tower, Doc managed to make his way across the clock and desperately tried to reconnect the chords. He was about to bring them together, only to discover the one he brought up with him wouldn't go further do to the branch Xemnas caused to fall on top of it.

Doc pulled with all his might, until he disconnected the chord from the one attached to the first lamppost below.

"Argh!" gasped Doc in realization. He then got an idea as he proceeded to plug the chord he brought with him into the one attached to the pole.

KH

Back at the starting point below, Marty continued to struggle getting the engine working, just as the clock went off, signalling it was time to go.

Soon, Donald had finally had as he shouted to the time machine, "Come on you big palooka! MOVE IT!" he quacked angrily, banging his fists so hard… it made the engine work!

"Nice work Donald!" cried Sora.

Donald, realizing what he did, smiled and blushed at the praise. "No problem." he told them. Marty then hit the gas pedal, and the DeLorean sped away.

KH

Back on the clock tower, Doc proceeded with his plan by attaching wire rope around the big arm on the clock, and slid down it to the ground. He let go at three feet, and landed in a leave pile. Quickly, he removed the tree branch, and quickly connected it to the chord attached around the lamppost. He looked ahead to see the time machine getting closer.

Marty pushed the throttle further and then it reached 88 miles per hour, just as the clock struck 10:04, lightning struck the clock tower, sending the electricity through the wires. Doc jumped backwards to avoid electrocution and watched as the electricity ran along the pole, into the hook as the DeLorean came into contact with it, generating enough power, and sending it along with Marty, Sora, Riku, Kairi, Mickey, Donald, and Goofy back to 1985, as it disappeared leaving a fire trail behind.

Doc got up and starred in awe at what just happened. He walked around the street as the fire trail disappeared.

"YEEEEEEESSSS!" he shouted triumphantly. He had done it. Marty, Sora, Riku, Kairi, Mickey, Donald, and Goofy had been sent back to the future. The Space Time Continuum was saved.
