This is a fic I wrote in the summer, mostly as a sort of laugh, and I've decided to post it here. It doesn't mean that I've given up on my other fic, Marty is Left Behind, because its last two chapters are already completed. I'd like to point out that I wrote this for fun, and the standard of writing is even lower than in my other fic; it's a complete rush job. Don't know for how long I'll continue this, I've only written the first two chapters. Enjoy, anyway.

'Yo, Doc!' called Marty, throwing his schoolbag to the floor. 'Where are you?'

'Marty!' Doc greeted him, poking his head out from underneath one of the workbenches, which was littered with tools. Doc conducted all of his experiments out here, well away from the house, by Clara's order. 'You made it.'

Marty grinned wryly, remembering those exact words on a November night last year – and what had occurred afterwards. 'Yeah. What did you want me for?' Doc had called last night, requesting Marty to come over after school, although he hadn't said why.

'Oh, nothing important. I was just going to take a little trip through time, and I thought maybe you'd like to come along, although you'll have to be careful not to say a word to Jules and Verne about this.'

'Sure!' said Marty immediately. Doc was extremely careful about travelling through time after they'd seen the consequences of one of their little trips; as a result the time-travel trips were rare nowadays. 'Where're you goin'?'

'Two hundred years into the future!' Doc looked more excited than usual. 'It'll be the furthest I've ever been. I was lying in bed last night, thinking about the future – and I was seized by an overwhelming desire to see how far humankind has gone, where we're going – '

'And why, Doc, yeah I get it,' said Marty. 'So you just want to go along into the future and look around?'

'Well, I was intending to purchase some parts for the train,' said Doc cheerfully.

'Much more advanced than anything I can buy here. And maybe a new security system for it…I'll see when I get there.'

'Right. Uh…are you sure this is gonna be OK?' said Marty nervously.

'Trust me, Marty. It's just one little trip into the future. What could go wrong?'

They drove up to the woods where Doc kept the train, locked in a reinforced shed. Most of the locks were futuristic; Doc wasn't taking any chances. They flew the train out, programmed 24 January 2200 into the time circuits, and hit 88.

As they blasted into the new time, the train skimming just above the ground, something shook the train so hard Marty, who hadn't been wearing a seatbelt, was slammed to the floor. He lay there for a moment, the breath knocked out of him. It felt like every bone in his body had been broken.

'Doc!' he managed to choke out. 'What the hell just happened?'

The scientist was standing at the window. Marty squinted at him, his vision still fuzzy – he'd whacked his head off the floor. Was it just his imagination, or did Doc look a little different? He rubbed his fists into his eyes, willing his eyesight to return to normal.

'We hit something,' said Doc. There was an odd tone to his voice.

'Figured as much,' gasped Marty, getting to his knees. When he looked up, the door was open. Doc had disappeared outside.

'What I mean,' his voice drifted in, 'we hit something that was originally here in our place.'

Marty's head was throbbing too much for him to try figure out what Doc was talking about. He clambered to his feet and staggered to the window.

What he saw outside made him wish he'd remained on the floor. Golden sand dunes stretching as far as he could see. Dust and canyons. A blazing sun in an azure, cloudless sky. It looked like a completely different world.

'Jesus Christ,' he whispered, clutching the ledge so hard his knuckles turned white. 'Jesus Christ! This is what Hill Valley looks like in two hundred years? Oh God…'

'Marty,' called Doc from somewhere outside, 'have you ever seen Star Wars?'

'What? What?' Marty blinked. 'You want to talk about Star Wars now? Are you insane?'

'Just tell me: have you seen it?'

'Well – yeah, of course…who hasn't?' Marty stared out at the barren landscape. There was something naggingly familiar about it. 'So what did we hit, Doc?'

'Not so much hit as – replaced,' he heard Doc's voice. There was definitely something strained about his voice. 'Meaning that we replaced something – or rather someone who was standing here before the train landed in this spot.' He paused. 'In an alternate world.'

'What the hell are you talking about, Doc?'

Doc appeared in the train's doorway again, at the bottom of the fold-down steps. It took Marty's eyes a moment to focus on the dark silhouette against the sunlit sand; when they did, his mouth dropped open and all speech left him.

Doc was not dressed as he had been when they'd left 1986. Then, he'd been wearing a short-sleeved shirt and slacks. Now he was clothed in long robes and a cloak –

Quickly, Marty glanced down at himself. He was stunned to see that he was also dressed differently – a loose, baggy top, weird legging-things, tall boots – why did these clothes seem so damn familiar?

Things began to fall into place in his mind. A weird desert world…Doc talking about Star Wars…Doc talking about how they'd replaced someone in an alternate world…Doc dressed like some Jedi Knight or something…

Marty looked at Doc, and then back down at himself. And then it hit him.

'YAAAAHHHHH! I'M LUKE SKYWALKER!'
