1985: Three sonic booms were heard as the DeLorean came zooming by before screeching by to a halt

Note: I accidentally said that the Lamborghini would go to 2015 even though I said that the temporal incursion occurred in 2017. Just pretend that I said that the Lamborghini would go to 2017 instead of 2015.

1985: Three sonic booms were heard as the DeLorean came zooming by before screeching by to a halt.

"Okay Marty, you have to find out what is different from our time to this one," said Doc.

"How do we stay in contact?" asked Marty. Doc handed him a walkie-talkie.

"Just like old times," said Doc. Marty nodded and left. As he reached city limits, he saw the Welcome to Hill Valley sign on the ground riddled with bullet holes.

"This is disturbingly familiar," said Marty to himself. As he walked into town, he saw two cars come racing down the town.

"Maybe now I'll get some answers," said Marty. But as the cars came closer, Marty saw that the people in the cars were firing at each other. Marty jumped to the side as he was almost hit by one of the vehicles. Marty kept walking onward and noted all of the burnt and destroyed buildings.

"Doc, this is looking just like the alternate 1985 that we visited when Biff Tannen traveled through time," said Marty.

"Collect a few newspapers and return back to the DeLorean," said Doc. Marty noticed several trashcan fires and the littered streets and several slums. He noticed that just about everyone was homeless and that not too much was going on in terms of being good neighborly. Marty eventually reached the library. He tested the doors and it was as he figured, locked. Marty slammed against the door a few times before realizing that it was hopeless.

"I can't get in," said Marty frustrated. Instantly a hand grabbed him on the shoulder. Marty turned around to see Biff's favorite goons: 3-D, Match, and Skinhead.

"I heard you were in town. We're bringing you in the hard way," said Match. He yanked out a club and hit Marty over the head knocking him out cold.

"Put him in the car," said Match.

"Isn't the hard way the same as the easy way?" asked 3-D.

"Shutup," said Match. The trio threw Marty in the car and drove away.

2017: three sonic booms rocketed in the sky as the Lamborghini appeared out of nowhere.

"Where's the skyway?" asked Sarah.

"Apparently in this timeline, it doesn't exist," said Jake.

"That's too bad," said Sarah. Jake brought the Lamborghini in low and landed just outside of Hill Valley's city limits.

"I've never been here before," said Sarah.

"Oh, well, at least it isn't like this in our timeframe," said Jake. Jake drove the Lamborghini for a few feet and parked it behind a large billboard. He then took out a small device that looked like a pocket pal.

"This is designed to locate the time machine that was used to alter time," said Jake. Sarah looked at the device, which showed a layout of the city and a blinking light.

"All right," said Sarah. She exited the car and walked off.

"Sarah," said Jake. She turned around and Jake handed her a walkie-talkie.

"Whoops, my bad," she said. She took the radio and turned towards the city. She then unzipped her backpack and took out her hoverboard. She then stepped and it and zoomed off towards Hill Valley. She noticed all of the smokestacks and all of the smoke that billowed out of them. As soon as she saw a few people she put her hoverboard away and walked into town. She noticed that it had turned into a slum and how different this time period was from hers. Her time tracker started beeping as the signal was approaching her position. She then noticed that all the people who had been moping around got up and stood next to the street. She then noticed a motorcade coming down the street. First there were some motorcycles, then some police cars, two tanks, a Winnebago, two tanks, some police cars, and finally some motorcycles. Above the Winnebago was a man who was waving his hands at the people. A banner was seen on the side of the street that read: Diff, son of Biff, father of Griff, is glad to be your new leader. Sarah watched in disgust as the people on the streets kneeled next to the motorcade. Sarah didn't want to kneel, but she had nearly been killed in the past when she hadn't kneeled, so she kneeled as well. After the motorcade passed and the bums went back to their corners, she yanked out the radio.

"Jake come in," said Sarah.

"What's up," said Jake.

"I found the time machine, it's the Winnebago," said Sarah.

"Wow," said Jake.

"Yeah, what should I do, it passed by in a motorcade that was escorted like the president," said Sarah.

"Find out what time it went to in order to alter the past and then blow it up," said Jake.

"I can't do that. It's against the law," said Sarah.

"In case you weren't aware, it doesn't seem like the law exists here," said Jake.

"All right I'm going," said Sarah. She then ran off after the procession.

1985: Marty started waking up and blinked his eyes a few times.

"Honey," said a familiar voice.

"Mom, I had this terrible dream that time was wrong," said Marty groggily.

"Relax, you're safe now on the 37th floor," said his mom. Marty's eyes went wide open as he heard this.

"37th floor!" he said in amazement. He then saw his mom whose appearance had changed since he had last seen her. She looked just like when he had seen her during that horrible version of 1985.

"Not again!" he yelled.

"What's going on in there!" yelled a voice that Marty instantly recognized as Biffs.

"Oh no," said Marty sighing. Biff burst through the doors and looked at Lorraine and Marty.

"Kid, what are you doing here, I shipped you off to Germany!" Biff yelled.

"Yeah well, I came back," said Marty. This statement caused Biff to glare at him.

"Be glad that he's your kid," said Biff to Lorraine before bursting out of the room.

"It's a good thing that your father is so lenient," said Lorraine.

"Yeah, right," said Marty bursting out of the doors also. Biff was in his office on the phone. Marty walked in and Biff glanced up at him and then glanced away.

"You heard me, I want some dirt on him and I want it now!" yelled Biff on the phone. He then slammed the phone shut.

"What do you want kid? I should shoot you for being here," said Biff.

"I came back for, for, for a school assignment," said Marty thinking fast.

"What assignment, the school promised me that you wouldn't ever be leaving there," said Biff.

"Yeah well, this one instance came up. As soon as I get the info, I'll leave," said Marty. Biff seemed to accept this statement seeing how it was that he didn't want Marty there any more than necessary.

"What do you want to know?" asked Biff.

"In detail how you acquired your wealth," said Marty.

"Oh all right. It all began on November 13, 1955. This time, the same guy who gave me the sports book, gave me a new one. This time I kept it safer and I betted on the winners. I made my money," said Biff. Marty stood up and was prepared to leave when he heard the clicking sound of a gun loading.

"Don't play me for a fool kid, I know that you were the one who stole the book from me," said Biff.

"That's not possible, time travel is impossible," said Marty stammering.

"I don't think that it is," said Biff. Biff took the gun and pointed it at Marty.

"Well, I guess that this is it. What the heck is that!" yelled Marty pointing behind Biff. Biff spun around like always and Marty made his escape. Biff turned around and saw Marty bolt. Biff growled in anger and started firing into the lobby. Marty ducked left and right trying to avoid the bullets. He then took out the radio.

"Doc, meet me on the roof," said Marty.

"Roger that," said Doc. Marty then burst into the stairwell and ran up the stairs to the top floor.

2017: Sarah was cautiously making her way through the town as she followed the motorcade. Eventually she saw the vehicles enter a garage next to a large hotel. Sarah figured that the hotel was at least forty stories tall. She then ran towards the garage and rolled under the closing doors. She then stood up and hid next to one of the tanks. She watched as everyone filed out through a pair of doors. She heard in the next room someone say Welcome King Diff. Sarah just shook her head. She then made her way to the Winnebago.

"Jake, I'm here, but I don't know if the Winnebago has any alarms on it," said Sarah.

"Then try the alarm scanner located just next to the rear right tire," said Jake. Sarah looked over and saw a panel with buttons on it.

"How many other time machines have this?" asked Sarah.

"I only equipped it on the larger vehicles," said Jake.

"How does it work?" asked Sarah.

"On the button panel type in 667 and then execute," said Jake. Sarah typed in the number and hit the execute button. A schematic of the Winnebago was shown and on it several lines appeared.

"There are six lines shown," said Sarah.

"Hit the button marked disable," said Jake. Sarah pressed the button and instantly the lines disappeared. Sarah then opened the door and walked inside. She then sat down in the driver's chair and hit the time circuits. The three rows of dials lit up.

"Here goes, the last time left is November 13th, 1955," said Sarah.

"Great, now blow it up," said Jake.

"How?" asked Sarah.

"Blow up the gas tank," suggested Jake. Sarah tried to figure out how to do it when she noticed the tank.

"I've got a better idea, get to the largest hotel in town and fly by overhead, I'll be coming out of the garage at the bottom, as soon as you see me, come and pick me up," said Sarah.

"Okay, I'm taking off," said Jake. Sarah put the radio away and walked up to the nearest tank.

"Time to put that combat training to work," said Sarah. She turned the tank turret to point at the Winnebago and pressed the fire button. The tank fired on the Winnebago and it exploded into a million pieces. The noise was heard outside and a commotion occurred as the door to the garage was opened. Sarah quickly spun the turret around and blew open the garage door. Sarah hopped out and ran off.

"Jake, where are you?" asked Sarah.

"I'm still five minutes away," said Jake.

"I'm headed down Seventeenth Street," said Sarah.

"I'll try and spot you," said Jake. In the garage, Diff looked at the destroyed Winnebago and growled in anger.

"Find the person who did this!" he yelled. An elderly Biff ran into the garage as well and noticed the demolished time machine.

"Time travelers," said Biff in terror as he realized that his days might be numbered. Sarah was running down the street when she noticed the bikers behind her.

"This is just great," she said. The bikers noticed her and were just about to hit her with a pipe. Sarah closed her eyes and waited for it to come. When the pain never came she opened her eyes and noticed the bikes toppled over on their sides. Hovering above them was the Lamborghini.

"Let's go!" yelled Jake. Sarah hopped in the car as it blasted away.

"Setting coordinates for 1955," said Jake.

"Shouldn't we go to 1891?" asked Sarah.

"Doc Brown isn't going back there, he's going straight to 1955," said Jake. The time machine reached 88 miles per hour and vanished into the past.

1985: Marty had just reached the roof and was waiting for Doc to come when he heard the gun click behind him.

"I knew it was you kid who traveled into the past and screwed me twice. I'm not going to let that happen again," said Biff. Marty then stepped onto the ledge.

"Do it kid, jump. That way I don't have to cover anything up," said Biff. Marty leapt off the ledge. Biff laughed and walked to the ledge. Instead of seeing Marty splattered on the ground, he saw Marty standing on the hood of the flying DeLorean. Biff raised his gun to shoot at Marty when the gull wing door opened and smacked Biff in the head. Biff was knocked out cold.

"That's strike two," said Marty who entered the DeLorean.

"When we headed to?" asked Doc.

"Once again to 1955," said Marty.

"Well, this is just too coincidental," said Doc. Doc set the coordinates for 19555 and gunned the engine.

"What about Jake and Sarah," said Marty.

"They'll be waiting for us there," said Doc.

"Okay," said Marty as the car vanished into the past.
