And now we meet Dr. Emmett Brown again… from 1955.

Night had fallen by the time Marty, Sora, Donald, Goofy, Mickey, Riku, and Kairi made it to the Doc's house. They had been telling Marty about some of their stories.

"Now that's a pretty heavy adventure. So do you think someday Roxas and Naminé will have their own bodies and hearts?" asked Marty.

"Gee, I hope so. I know how much Lea misses them." replied Sora.

Marty turned to Goofy. "And it's hard to believe you nearly died! Sure it was to save Mickey from getting crushed by a boulder, but that's just scary to think about!"

"I guess, but I do care for my friends that much. I'd do anything for them. A-hyuck!" replied Goofy. "Besides, I get bonked on the head all the time!"

"Kinda disturbing when you put it that way." Marty quipped.

"Well sure, when you put it that way."

"Yeah, the six of us are a family together." added Mickey, smiling.

"That's really sweet." smiled Marty. Then, he noticed something. "We're here!"

The team looked in awe. Right beside Doc's garage was a giant house.

"Whoa!" exclaimed Sora.

"Gosh!" exclaimed Mickey.

"Neat digs!" commented Donald. "Just like my uncle's."

"So this is what it looked like before that fire happened." said Kairi. "It's so big and spacious!"

"Such a shame the mansion burned down some time in the future." said Riku.

"Yeah but Doc doesn't really mind." said Marty.

"Maybe some other day in the future he can get it rebuilt." suggested Sora.

"If people stop calling him a crackpot then yeah." Marty nodded.

The seven heroes walked to the Doc's door. Sora knocked, but nothing happened. After a few seconds, the door opened to reveal a younger Doc Brown… with a weird contraption on his head. They also noticed a bandage on his forehead, probably from hitting his head on the sink.

"Don't say a word!" he ordered, ushering them inside.

"Doc wait-" began Marty as Doc took a device off a puppy that looked similar to Einstein, even though it clearly wasn't him.

"I don't want to know who you are or where you're from!" said Doc.

"Doc I-" started Marty.

Doc then placed a suction cup on Marty's forehead. "I'm going to read your thoughts!" Marty sighed in exasperation as Sora and Co. watched on, confused. "Let's see… you all come from a great distance…" began Doc.

"Yes! And-" began Marty.

"NO! Don't tell me! Let's see… you want me to buy a subscription to the 'Saturday Evening Post'." guessed Doc.

"No, Doc-"

"Hold that thought! Um… Donations! You all want me to make a donation to the 'Coast Guard Youth Auxiliary'!" guessed Doc. Sora and Co. sighed.

"This is exasperating." muttered Donald to Riku, who could only nod.

"Uh… I GOT IT!" exclaimed Doc. Everyone thought he had finally figured it out.

"Disney characters… you want me to join The Mickey Mouse Club!" guessed Doc. Donald facepalmed.

"Doc… (takes off the suction cup) We're from the future. (points to the world-travelers) THEY'RE, from different worlds, here to protect ours from the Darkness. We need your help to get us back to the year, 1985." Marty explained as calm as he could.

Doc stared speechless for a few seconds before approaching them. "My gosh… do you know what this means?" he asked.

Everyone looked at him hopefully.

"It means that THIS DAMN THING DOESN'T WORK AT ALL!" Doc shouted, taking off the helmet.

"Doc, you gotta believe us, you're the only one who knows how your time machine works." pleaded Kairi.

"Time machine! I never built any time machine…" mumbled Doc.

"How can we prove we're from the future?" asked Goofy.

Sora had an idea. He then summoned his Keyblade. Getting the idea, Riku, Kairi, Donald, Goofy, and the king summoned their weapons too.

"What do you think of our futuristic defense weapons Doc?" asked Sora.

"Can't deny this." added Donald.

Doc looked at them. "Hmm… that doesn't mean you're from the future!" he said. "You could've just used smoke and mirror to do that!"

The heroes dismissed their weapons in frustration.

"Doc, come on!" groaned Marty. He pulled something out of his pocket. "Look at my driver's license. See? 'Expires 1987'? Look at my birthday, I haven't been born yet!" explained Marty. Nothing. He pulled something out from his wallet. "Hey, check this out, this is a picture of me, my brother, and sister."

The picture showed Marty, Dave, and Linda standing in front of a wishing well. Linda was wearing a "Class of '84" sweater. Dave was wearing a red Mickey Mouse shirt. Ironically, no one noticed.

"See, class of 1984?" asked Marty, referencing his sister's sweater. "You gotta believe me." he pleaded.

Doc looked closely at the picture by picking it up with tongs. Dave looked normal, but Doc noticed the top of his hair was slightly faded.

"Mere photographic forgery, they cut off your brother's hair." scoffed Doc.

"Doc, come on! We're all telling the truth!" pleaded Donald.

"Well then, tell me 'Future People,' who is President of the United States in 1985?" asked Doc.

"Ronald Regan." replied Marty.

"Ronald Regan?! The actor?!" Doc asked incredulously, grabbing several blueprints. "Then who's vice president?! Jerry Lewis?!" he asked, sarcastically as he ran for the door.

"I suppose, Jane Wyman is the First Lady!" shouted Doc sarcastically as he ran for his garage.

"Whoa wait Doc!" called Marty as he, Sora, and Co. ran after him.

"Come back here!" Sora called.

"And Jack Benny, is Secretary of the Treasury!" he added.

They reached the door.

"Doc please, you gotta listen to us!" pleaded Sora.

"I've had enough jokes for one evening! Goodnight 'Future Boy' and friends!" he called as he shut the door.

"Doc come on… I-That bruise on your forehead! We know how you got that!" exclaimed Marty. "You were standing on your toilet, hanging a clock over it when you slipped and hit your head on the sink! And when you came to, you had the idea for the Flux Capacitor, which… is what… makes time travel… possible." he finished, tired. Sora patted his back as a sign of comfort.

Suddenly, Doc opened the door and stared at the seven, with a blank but astonished expression of surprise.

The seven arrived back at the spot where they hid the DeLorean on Sora and Kairi's gliders. Doc examined it in surprise. Riku showed him the Flux Capacitor.

"After I hit my head, I had a picture in my mind that I quickly drew down." said Doc, pulling out a piece of paper with a picture of the Capacitor drawn in pencil. "I just can't believe something I invented actually works!" he exclaimed.

"You bet your butt it works!" replied Donald.

Back at Doc's garage, the DeLorean had been placed inside and Marty, Mickey, and Donald were trying to get 1985 Doc's video camera up and running on an old fashioned TV. Sora, Kairi, and Riku watched them while Goofy talked to Doc.

"Fascinating how there are many worlds out there, and that you travel to everyone to protect them from the Darkness," he remarked.

"Yep, but promise you and Marty won't tell anyone? It's to protect the order." said Goofy. Sora and Mickey looked at him with familiar smirks. "…Even though no one really cares. A-hyuck!" he added.

"Lips. Sealed." promised Doc.

"Your future self said that too! A-hyuck!" chuckled Goofy.

"Okay Doc, this is it." said Marty.

All 8 gathered around the TV as Marty's recording began to play.

"Never mind that, never mind that now, never mind that, never mind-"

"Why that's me, look at me, I'm an old man!" Doc exclaimed.

"Good evening, I'm Doctor Emmet Brown, I'm standing here on the parking lot of-"

"Thank god I still got my hair." Doc commented before looking closer. "What on Earth is that thing I'm wearing?" he asked.

"Well, this is a radiation suit." Marty replied.

"Radiation suit, of course, cause all of the fall out from the atomic wars." nodded Doc. He looked at the video camera. "This is truly amazing, a portable television studio. No wonder your president has to be an actor, he's gotta look good on television."

Sora, Donald, and Goofy chuckled at the remark while Mickey, Riku, and Kairi, rolled their eyes, still smiling.

"Whoa, this is it, this is the part coming up, Doc." said Marty as he stopped fast-forwarding.

"No, no this sucker's electrical. But I needed a nuclear reaction to generate the 1.21 jigawatts of electricity I need!" said the recorded Doc.

"What did I just say?" asked Doc.

Sora rewound the footage.

"No, no this sucker's electrical. But I needed a nuclear reaction to generate the 1.21 jigawatts of electricity I need!" repeated the recorded Doc.

"1.21 JIGAWATTS?!" Doc shrieked. He picked up Donald and shook him around. "1.21 jigawatts!" he said incredulously as he dropped him on the ground and Donald landed with a "WAK!"

"Sorry Donald!" Doc said as he ran to his door. "GREAT SCOTT!" he yelled, running out the door.

"What… What the hell is a jigawatt?!" cried Marty who ran after Doc, followed by Sora and Co.

Doc was sitting in his chair in his house.

"How could I have been so careless?! 1.21 jigawatts?!" he groaned as he looked at a picture of Thomas Edison. "Tom! What am I gonna do?! How am I supposed to generate that kind of power?! It can't be done! CAN'T!" yelled at the picture as the seven heroes came in.

"There he is!" pointed Sora.

"Doc, calm down and quit yelling at Thomas Edison!" said Mickey.

"Yeah, all we need is a little plutonium and we're good to go!" said Kairi.

Doc set the picture on top of his fireplace. "Oh, I'm sure that in 1985, plutonium is available in every corner drug store in the state!"

Donald and Goofy looked at each other with worried expressions and shook their heads.

"But in 1955, it's a little hard to come by! Everyone, I'm sorry, but I'm afraid you're all stuck here!" Doc said.

"What?! No Doc! We can't be stuck here! I've got a life in 1985! I got a girl!" exclaimed Marty.

"Is she pretty?" asked Doc.

"Doc, she's the best, heck she wrote her number for her grandma's for where she's staying over right now. She's nuts about me!" said Marty, showing the flyer.

"And besides, we can't stay here either! There are other worlds that need help! And our transportation is back in 1985!" added Sora.

"Plus, I promised Daisy and date when we come back home! And I promised my sister I'd take care of her kids if something ever happened to her! Sure maybe Uncle Scrooge and Uncle Ludwig could do it, but I can't put that pressure on either of them with all they have to do!" added Donald.

"And I have a son back at the castle! I promised I'd protect him with my life after his mom died!" added Goofy.

"I thought you said he was in college," said Marty.

"Yeah, but he lives with us whenever he isn't at the school, helping us run things." answered Goofy.

"And Sora, Riku, and I have families! They'll be worried sick! And what happens when we return to them as 40-year-olds when we finally get back?!" added Kairi.

"And then there's my Minnie! I can't put all that pressure on her by having her run the castle by herself for 30 years!" added Mickey. 'Plus Mortimer might try to take advantage of that.' he bitterly thought to himself.

"You see Doc, with all that and many, MANY, more… Well, you're our only hope!" finished Marty.

"Marty, Sora, everyone, I'm sorry. But the only other power source capable of generating 1.21 jigawatts is the power of LIGHTNING!" said Doc, hopelessly.

Sora and Donald exchanged a look. "Lightning eh?" asked Donald.

"Simple, me, Donald, Riku, Kairi, and Mickey can use the Thunda Spell to generate the lighting," said Sora.

Kairi and Goofy nodded, but Mickey and Riku shook their heads. "I'm sorry Sora, but we can't. Thunda is way too powerful." said Riku.

"He's right. It's so powerful that it could end up destroying the DeLorean." added Mickey, sadly.

"Aww phooey!" grumbled Donald.

"We could always use normal lighting, but you never know when or where one might strike." groaned Doc.

Suddenly, a lightbulb went off in Marty's head. He pulled out the "Save the Clock Tower" flyer. "We do now." he said, showing it to the others. Sora, Riku, Kairi, Mickey, Donald, and Goofy gasped as they saw that Marty was holding their answer. Doc grabbed the flyer, read it, and his eyes went wide.

"This. This is the answer! It says here that on this Saturday, November 12, 1955, lightning will strike the clock tower at 10:04 p.m.! If we could somehow harness this lightning and get it into the time machine, we could generate enough energy to send you all back! This Saturday, we're sending you all back to the future!" exclaimed Doc, pointing ahead.

"Uh… who's he pointing to?" asked Goofy, looking in Doc's direction and scratching his head.

"You got me." shrugged Sora.

"Only a week in 1955." murmured Riku.

"That sounds fun!" giggled Kairi.

"Yeah! It'll be like our own personal vacation!" added Sora.

"Well, it's been a while since we lived throughout the 50's. It'll be nice to relive those days. A-hyuck!" chuckled Goofy. Donald and Mickey chuckled too.

Doc turned to them all. "Everyone, that's completely out of the question, you must not leave this house. You must not see anybody or talk to anybody. Anything you do could have serious reprocautions on future events. Do you understand?" he sincerely asked.

"Yeah, sure, okay." nodded Marty.

"But what about the Heartless? They're a pretty big problem too." remarked Sora.

"Yeah, they could mess up the future as well." added Goofy.

"Ok, you can go deal with them when necessary. All the same, you can't risk anything or you risk altering the future." said Doc.

Sora, Donald, Goofy, Riku, Kairi, and Mickey traded nervous glances. Doc noticed this.

"You all did something, didn't you?" he asked suspiciously.

"Uh… maybe?" Goofy said, rubbing his arm.

"Everyone, have you interacted with anybody else today, besides me?" Doc asked.

"Crazy farmers who thought we were aliens and tried to shoot us in the dark." grumbled Donald.

"The ones who breed pine trees or something." Sora chimed in.

"Well, that's Old Man Peabody for you." chuckled Doc.

"As well as this bully named Biff Tannen." added Kairi. "He tried to 'pick me up'."

"And we may have sort of run into my parents." finished Marty.

"Your parents?! Great Scott!" exclaimed Doc.

"Something wrong Doc?" asked Riku.

"Let me see that photograph again of your brother!" commanded Doc. Marty pulled out the picture, and the others noticed that the top of Dave's head was fading. "Just as I thought, this proves my theory, look at your brother!"

Everyone looked.

"His head's gone, it's like it's been erased." gasped Marty.

"Erased from existence." Doc replied.

"Oh no…" mumbled Mickey, concerned.

"Not good…" said Riku in agreement.

"Oh my god…" Marty exclaimed, almost panicking.

"Marty, Marty calm down." Sora said quickly.

"Marty, we're gonna fix this!" said Kairi.

"Are-are you sure?" Marty asked.

"Of course we can!" said Sora. "Our job is to protect the worlds. And that's what were gonna do."

"He's right!" said Goofy. "We're heroes!"

"And we'll save the timeline!" said Donald.

"Including your family." added Mickey.

"We'll make sure you see your family again. Jennifer too." Kairi said, patting Marty on the back.

"Oh thanks guys…" Marty sighed in relief.

"Tomorrow, while we keep an eye out for Heartless, we will go to school and Marty, you will show me what your parents look like! That way we can help them get together, ok?" asked Doc.

"Yeah, got it Doc." replied Marty.

"Gawrsh, I hope we can get them together before it's too late." said Goofy, concerned.

"Don't worry, while protecting this world, we can do it! The McFly's will be saved in no time!" motivated Sora.

"That's our Sora, always optimistic." chuckled Kairi.

"And lazy." added Riku with a smirk.

"Say that again!" challenged Sora, still smiling.

"Alright fellas, let's get some sleep. Tomorrow, we got school." declared Mickey, before chuckling at that last statement.

Everyone laughed and they got ready for bed. As they did, Sora turned down to face Mickey. "You don't think this counts as meddling do you?" he asked, nervous.

"Naw, I don't think so Sora." replied the mouse king with a reassuring smile. Sora smiled back.

Castle that Never Was:

In the grey room, Xemnas watched the heroes get ready for bed as he smiled.

"We'll see about that you pathetic heroes. We'll see…"

At that moment, Saïx teleported in.

"Xemnas. I see you're still awake." he said.

"The Keybearers have just realized that they interfered with the timeline." Xemnas replied, not looking back at the bluehead. "Now they will be trying to fix it. This is an opportunity for us all to interfere, and cast the world of Hill Valley down into the darkness."

"How do you plan to do it?" asked Saïx.

Xemnas walked past him. "Basic attacks first… then we will have more time to plan a bigger approach in making sure they fail." the old Organization's Number I replied.

"And in trying to stop us, they run the risk of wrecking the timeline further." nodded Saïx.

"Exactly." said Xemnas. "Hill Valley will be in ruins. Maleficent will enjoy that. So will Xehanort. We'll see how the Keyblade Wielders fare then. It won't be easy for them as the steaks go higher."

And Xemnas walked out of the room.

Saïx watched him go. If Xmenas had bothered to look back… he would've seen a smirk appear on the Luna Diviner's face.

To be continued…

Done again! We're halfway done too!

Rate, review, and I'll see you all soon!
