Author's Note: Here we go, the story for the SmartMarty Universe! The idea is that Doc and Marty's intellects are reversed and increased. So, alternate Doc (Emmett, as he wouldn't be able to get a doctorate) is less intelligent than 'normal' Marty, and Smart Marty is more intelligent than Doc is. My idea of SmartMarty is as follows: lab coat, messy brown hair, blue eyes with insane look in them, and the highest IQ on the planet. He still likes rock music, even though he's not really pursuing a career thanks to his other big interest: science. Taking away Doc's scientific part leaves behind the 'cowboy' thing, which he claims in the start of Part III to have always wanted to be, and therefore, this Doc is a horse dealer. He has a horse ranch on the site of his old mansion, which never burnt down.

Now, let's get going. Enjoy!

EDIT: BTW, I uploaded the wrong document earlier on. This is the right one.

Disclaimer: I don't own BTTF. I also don't own the idea of a smart Marty. It has been thought up by other authors before.

1: Chapter One

At the parking lot of Twin Pines Mall, a nervous Emmett Brown, who was running down to the lot, checked his watch. 1:19 am. He was expected right here at one-seventeen… knowing Marty, the teen would probably be furious with him. Marty was very punctual, ever since he once arrived late on school in 1977 and had to miss a science lesson, which he, being a science lover, of course was horrified at. Ever since that, the teen had vowed never to be late for school again, and had been right to his word. That was especially why it was weird that, right now, Marty was nowhere to be seen.

Emmett looked around in surprise as he realized that. Indeed, the parking lot was empty. What was going on? Marty was always right on time. The horse dealer scratched the back of his head, and frowned. What could be happening?

Right then, he heard some noise from behind… car noises. As Emmett looked behind him, his mouth fell open as he recognized Marty's Toyota truck, driving there, with Marty behind the wheel. The teen grinned at Emmett, as the older man watched with his mouth wide open at the Toyota riding up to him, modified with all kind of wires and equipment, and most obvious, a large bucket-thing three times the size of a garbage can, attached to the back. "Nice, huh?" Marty couldn't help but say.

Emmett simply gasped. "This is heavy…" he groaned. "What does this thing do?"

Marty stepped out, grabbing a remote control from the back seat. "Your questions will be answered in just a few moments" he told his friend, and he turned to the mall entrance sign. "749, it's show time!"

A young horse came running up to the two time travellers-to-be. Emmett stared at Marty, horrified. "Marty, not 749!" he groaned. "He's one of the best horses I've got! Why do you want to kill him with another one of your mad experiments?"

"I'm not planning to kill him" Marty said, helping the horse into the truck. "And it's not a mad experiment either… I've spent years perfecting this." It took a while squeezing, but finally, the horse sat. The teen inventor then looked at his watch. "1:21" he muttered. "I'd better hurry."

"What do you plan to do?" Emmett protested, not sure whether to be angry, frustrated, horrified, terrified, excited, or a little of all of them. "You're not killing 749, are you?"

"Trust me, Emmett" Marty said, reassuring. "I've tested this out in theory many times. It is safe."

"Then what are you plan-"

Emmett's words were cut off as a glassy thing formed itself a roof over the car. "-ning to do" he finished, astonished. "What the heck is that for?"

"Solidifying the dispersal field" Marty said, stepping a few feet away from the car.

"What's the…"

"Stand back."

As the teenager had just said that, he pulled the lever, and the truck raced off through the parking lot. Emmett looked amazed as the truck came to a halt a good twenty yards away from him, and Marty made it do a vertical turn. The teenager then grabbed his friend's arm, and backed off a few more yards. Then, he stood still, right in the path of the truck.

"If my calculations are correct," he said, grinning, "when this baby hits eighty-eight miles per hour… you're going to see some serious external human food waste disposal."

Emmett just had time enough to grasp that, when Marty pulled another lever, and the truck started accelerating, while staying on one place. It hissed, it shot fire, and for a moment, Emmett thought it would explode, and then, Marty hit the other lever, and the truck shot out of it's position and forwards, towards the two of them. Emmett let out a shriek and tried to step out of the truck's path, but Marty grabbed his arm, eyes focused on the speedometer. "Watch this, watch this!" he called out, completely fascinated by the scene.

Emmett watched, terrified, as the truck began to get a fireball in front of it. As it was nearly at their site, it suddenly exploded in a flash of white light with a loud bang, leaving behind fire trails which Emmett could just avoid by jumping up. As the light cleared up, just moments later, the spot the truck had just been on was completely empty.

"Holy shit!" he called out. "You disintegrated 749! You said it wouldn't happen!"

"Calm down!" Marty called out, excitedly looking at the speedometer. "I didn't disintegrate anyone or anything! Look at the speed, eighty-eight miles per hour! 141.62 kilometres an hour! It happened exactly as I calculated, at one twenty-two A.M. and seven seconds! Means it'll be fifty-three seconds before we'll catch up to the temporal field warping and transportation machine again!"

"Time machine" Emmett muttered, getting what Marty was saying just barely. "It can't be."

"It's true" Marty said, grinning. "This is what you call a 'time machine', which might not be the appropriate term for it, as a clock could be viewed as such, as well, as it is a machine and gives the elapsed time since midnight or noon. Anyway, I conceived the idea for this device years ago, in 1978. Remember how I was knocked out in early March?"

"Yeah" Emmett said. "You gave me quite a scare."

"That was when I came up with time travel" Marty said. "It took me all the time up until now to make it work, but it works. I sent 749 to one twenty-three, and he will arrive there in…" He checked his watch, and gasped. "Great Scott, six seconds! Get out of the way, Emmett!"

Emmett ran a few feet away, and Marty followed him, but they'd just started to run as three loud bangs shattered and three flashes of light appeared and the truck re-appeared at eighty-eight. Marty, whom the truck had just missed hitting, regained control of his senses soon and hit the 'brakes' on the remote control. A few yards away, the truck screeched as it froze to a halt with a lot of noise. It also appeared to be smoking.

Emmett looked at the truck, dumbfounded, but Marty headed over to it, only to back off when steam came out of it. He gasped, then walked forwards again and opened the door, trying to ignore the low temperature.

"Ah, there you are, 749!" Emmett called out, running over. "He looks completely intact!"

"He is" Marty said, grinning. "He skipped over those fifty-three seconds so he was unaware that anything besides some bright flashes ever happened. He should be fine, theoretically, and I don't doubt he is. His molecular subatomic structure is completely intact, or so it appears."

"Well, you're the Doc, Marty" Emmett said, smiling, as they led the horse out of the DeLorean.

"Not yet" Marty said, grinning. "I'm still working on finishing college, and then, I can spend my additional year for my doctorate from 1986 to 1987. I do hope to become a doctor, someday, and… well, I guess that, with this at my disposal, I can actually find out if that ends up happening, someday. After all, this is a temporal field warping and transportation machine."

"You're planning to go to the future?" Emmett guessed, realizing what Marty had implied when saying 'I can actually find out if that ends up happening'. He was surprised at himself actually managing to find that out, as he still felt completely dazed from everything that had happened.

"Right on the alternative term for currency" Marty said, smiling. "Thirty years into the times that have yet to come from the world's current perspective. I've always dreamed of seeing the times that have yet to come from the world's current perspective, seeing the progress of mankind, and perhaps even my own, although I should be very careful around that. No human being should know too much about the part of their own life path that has yet to come."

"Yeah, I suppose so" Emmett said. "I'm going to miss you, though."

"Don't worry, I'll be back before you know it" Marty said, grinning. "And then, you can chose a destination. Have you got an idea when you want to go, yet?"

"How about the 1950s?" Emmett suggested. "I came up with the idea of my current ranch in 1955… I'll type in the date for you." He reached over to the time machine, then looked up sheepishly. "Uh… if you show me how it works, first."

Marty smiled faintly. "Simple" he said, moving over to the panels. "First, you turn the temporal field defining circuits on. You may call them time circuits if you like. They define the time which you end up in." He turned a switch, and three displays jumped to life, the upper one reading 'OCT 26 1985 01:23 AM', the middle one reading 'OCT 26 1985 01:25 AM', and the bottom one reading 'OCT 26 1985 01:22 AM'.

"See, this is how it works" Marty explained. "If you want to see the signing of the Declaration of Independence, for example, you tap in 07041776… leaving the time of day aside. If you want to witness the birth of Christ, you simply tap in 12250000. Granted, it is highly unlikely that said date is actually right, as there is no information about the place in time of that event, but let's just assume that it's correct for the moment. Of course, then you'd have to find your way to the places where said thing happened, but this makes it possible to go there, at least."

"May I try?" Emmett asked.

"Go ahead" Marty offered.

Emmett stepped in, admired the circuits for a moment, and then he typed in November 5th, 1955, at eight-twenty-two A.M. "That's the day and time when I came up with the idea" he explained. "I tried to hang a painting of one of my favourite horse riders onto the wall, and then I accidentally dropped it on my head and knocked myself out with it – that tells you enough about my lack of technical skills." He smiled sheepishly. "I came up with the idea for my ranch after I woke up. I'd love to see that for real again, especially from another… perspactive."

"Perspective" Marty corrected.

"That, yeah" Emmett confirmed. "I didn't act on my thoughts, though, until a few weeks later, in late November."

"That sounds not too bad" Marty said, smiling. "You do have to be careful, though, that you aren't seen by your younger self. If you somehow cause yourself not to start a ranch, then you might sell the mansion, and some buildings that weren't built previously would be built on the land. It would change history in a drastic way."

"Got it, Marty" Emmett said, smiling. "So, are you going, now?"

"I first have to reload" Marty said. He walked over to the other side of the mall, where ten bags of garbage were standing. He soon returned with two of them. "I built a basic fusion reactor into the truck" he said. "It runs on garbage to create 1.21 gigawatt's." He then held one of the bags above the huge bucket, and Emmett watched as all the trash fell down. He then held another one above it, and this fell down, too. Afterwards, he threw the bags inside, as well, and closed the reactor.

"Where did you get all that garbage from?" Emmett asked, as Marty walked over to the front of the truck.

The teen turned around, and smiled. "I did a simple job at a garbage truck two weeks ago" he said. "I kept ten bags for myself, and turned five others in. I'm lucky not to be caught for that, as it's illegal to keep the trash."

"Yeah" Emmett nodded. "I can't believe you did that. You never stole anything before."

"It's not really stealing" Marty said, defensively. "Those humans did not need the waste any longer. So I helped them by getting rid of it."

"Yeah, right" Emmett said.

Marty then remembered something. "Wait a second!" he exclaimed. "If I want to go and actually return to my point of origin, I'd need two more bags of garbage! How could that have slipped off my neural connections!"

The horse ranch owner shrugged. "I don't know, I forgot, too."

The teenager nodded, absent-mindedly. "Yeah, right" he muttered, and ran over to the garbage cans. Or, at least, he started running over to it, then stopped as he heard police sirens. Soon, a police car was on the parking lot. It stopped, and two men with guns stepped out.

"Marty McFly?" the left guy asked.

"Yeah" the teen genius asked, sceptical.

"You've been reported stealing trash" the right guy said. "Also, we have reports that said trash bags contained a secret microchip stolen from a foreign base. Therefore, we have concluded that, since no one steals trash, you are suspected. You will be arrested now."

"Like the place one goes to after having lived a bad life I will" the teen snapped. "I don't know anything about the microchip, and I'm not coming with you!" He ran off towards the truck, trying to escape.

The police man frowned. "We should've expected this" he said. He then turned to his colleague. "Open fire."

The left guy raised a gun, pointed it at Marty, and pulled the trigger.

"No!"

Everyone gasped in terror as Emmett, furious, jumped in front of his friend, and the bullet hit him. He groaned in pain, then went down. Marty gasped, and soon, a high-pitched horrified scream escaped his mouth.

"NOOO!!!!!!!!! Descendants one generation removed of a male and female human who are engaging in an illegitimate relationship!"

There was a short silence. "What?" the left officer finally asked.

"He means bastard" the right officer clarified. "Not that big words are going to help him, though." He raised the gun again at Marty, pulled the trigger, and found it jammed. "No…" he muttered, annoyed. "Stupid gun!"

Marty looked at Emmett, then at the officers, and dived into the truck. He shut the door, and made sure the roof was shut as the gun stopped jamming and started firing again. Then, he hit the gas, and raced out of the parking lot.

The officers exchanged glances, and soon, they started following him around the parking lot, accelerating rapidly. Marty hit the gas, too, and soon hit sixty, then seventy, then eighty.

He only noticed he was at eighty-six when it was far too late already.

Marty tried to hit the brakes, but it was not on time anymore. Just before that, the speed clicked to eighty-eight, and the brakes jammed at that, something Marty had installed previously as not to get too fast and therefore get any near-time travels, which would take up the energy. Now, he wished he hadn't installed it, though. Within seconds, a bright flash appeared, and the truck raced right through the time barrier into 1955.
