Disclaimer: I do not own Back to the Future.

Authors Notes: In an improved future, Marty Jr is just like his father was as a teen. Harmony Brown is Jules' future daughter - making her also Doc Brown's future granddaughter. Also, I have ruled that Michael J Fox does exist in my BTTF Universes - even though he doesn't actually appear in this story. It's just the BTTF Trilogy that obviously does not exist in my BTTF Universes. This story takes place in my Trilogy Universe.

Marty McFly Jr was taking turns playing Wild Gunman at the Cafe 80s with his best friend, Harmony Brown. Marty Jr was five feet four inches tall, had medium length brown hair and slate-blue eyes. Harmony was five feet two inches tall, had long golden-blonde curls, and bright blue-green eyes. They were two of the most popular kids in school - although, they were both far from being snobs. Both Marty Jr and Harmony were very friendly and easy-going - and they tried to see the good in everyone.

'You certainly are a Crack Shot, aren't you, Marty?' laughed Harmony.

'Yeap, I'm a Crack Shot,' replied Marty Jr, smiling, 'just like my dad.'

'It's amazing how so many people think that you and your dad are actually brothers,' remarked Harmony, laughing. 'I guess your dad was slow to age, just like Michael J Fox was.'

'Yeah, everyone comments on how my dad look so much like Michael Fox,' replied Marty Jr. 'Also, me, too, for the matter. I'm amazed at how much that Alex P Keaton charactor on Family Ties resembles me - except that I'm a liberal. Come to think of it, I wonder how many kids in our generation even watch re-runs of Family Ties.'

'Well, you might be surprised,' said Harmony, with a smile. 'After all Cafe 80s is a relatively popular hang-out with teens.'

'Yeah, yeah, that's true,' agreed Marty Jr, laughing. 'I guess the 80s are considered cool again, in a retro sense.'

The a smile spread across Harmony's face, and she whispered, 'Quick, Marty, let's head outside. I need to tell you something really, really important.'

'What is it?' whispered Marty Jr.

'Let's wait until we're alone,' urged Harmony. 'What I'm about to tell you has to remain strictly our secret.'

'Oh, sure, of course,' replied Marty Jr, smiling.

After heading outside and walking for about two minutes, Harmony looked around, to make sure they were alone. Then Harmony turned to Marty Jr, and said, 'Psst, Marty, I've found a way for us to visit our favourite decade, the 1980s.'

'Oh, you're kidding, Harmony, right?' Marty Jr asked, laughing.

'Actually, no, I'm not,' protested Harmony. 'I found an old time machine in Grandpa's lab - with instructions on how to make it work.'

'Well,' sighed Marty Jr, 'ordinarilry, I would laugh the idea off as ridiculous and impossible - but, since we've been best friends our whole lives, I guess I'll have to give you the benefit of the doubt.'

'Thanks, Marty,' Harmony replied. 'Grandpa will be gone for a whole week, so here is our chance to borrow the time machine, and go back to the 1980s. Meet me by 5:30, okay?

'Check,' replied Marty Jr.

oooooooooo

As promised, at 5:30 PM, Marty Jr had met Harmony at Doc Brown's house. He was wearing a red tee-shirt, covered by a black and grey checkered buttoned shirt, with a jean jacket over it, and then a red vest that looked somewhat like a life preserver. He was also wearing a pair of blue jeans with suspenders, along with some Nike running shoes. His whole outfit was handed down from his father.

'Hey, Harmony, are you here?' asked Marty Jr, as he reached Doc Brown's house. 'Where are you, Harmony? It's me, Marty.'

'I'm over here, Marty,' Harmony called out, from the shed that was standing behind Doc Brown's house.

Marty Jr ran over to the shed - as Harmony opened up the shed door.

'This is it!' exclaimed Harmony, as she was pointing over at the DeLorean. 'This is the time machine.'

'Um, well it's a DeLorean, right?' asked Marty Jr, stunned. 'Wait a minute! Wait a minute, Harmony! Are you telling me that your grandpa built a time machine - out of a DeLorean?'

'The way I see it,' replied Harmony, 'if you're gonna build a time machine into a car - why not do it with some style? Besides, the stainless, steel construction made the flux dispersal... Oh, geez, now I'm starting to sound just like my grandpa!'

Then Harmony stepped into the DeLorean, and turned on the time circuits. 'Well,' said Harmony, 'I guess this readout tells you where you're going, this one tells you where you are, this one tells you where you were. You input the destination time on this keypad. Where should we go?'

Marty Jr thought for a moment, then suggested, 'Hey, how about let's go to April 5, 1986? That would be exactly 30 years ago - and that's when my dad was the same age as we are now.'

'Good idea!' exclaimed Harmony. 'Let's go for it! We can finally experience life as a teenager, in 1986!'

'So, how does this thing travel though time, anyway?' asked Marty Jr.

'Well, first off,' Harmony explained, 'my grandpa had a vision of something called a flux capacitor, when he standing on the edge of his toilet hanging a clock, then he slipped and hit his head on the sink. The flux capacitor is the thing that makes time travel possible. The accident took place on November 5 of 1955. Incidentally enough, that was also the same day that your dad showed up in 1955, when he was our age.'

'Oh, wow, this is heavy,' replied Marty Jr. 'So how do we work this time travel device?'

'Well, first off,' explained Harmony, 'even though my grandpa made this car in the 1980s, he was able to take the car over to 2015, to get it hover-converted. Of course, one of the few drawbacks you had to worry about back in the 1980s was traffic. Still, I think the 1980s was a damn awesome decade!'

'Yeah, really,' agreed Marty Jr. 'I mean, people laugh at me, because I like to play old-school video games. Many of our peers believe that if you have to use your hands, then it's a baby's toy.'

'I'm so ashamed of our generation,' grumbled Harmony, rolling her eyes. 'Baby's toy, my ass! Try telling that the teenagers of the 1980s - try telling that to your dad.'

'Oh, yes, my dad and I have always been so close,' sighed Marty Jr, holding up his right hand, and crossing his middle and index finger. 'Everybody tells me that I have such a cool dad. We have the same taste in music, video games, and everything! I must admit that I'm spoiled.'

'Yeah, but you are so not a spoiled brat,' Harmony replied, coyly. 'You are such a sweet, easy-going, sensitive person. I'm sure that your dad was every bit as cool as you are, when he was a teenager.'

'Yeah, I wouldn't doubt it,' replied Marty Jr, cheerfully. 'Well, then, Harmony, shall we go, now? Shall we rock and roll?'

'Oh, yeah, for sure!' replied Harmony. 'We'll just need to fly this baby to 88 miles an hour, then we'll travel back in 1986. Say, we should maybe set our destination time to 4:00 AM on that date - so that people don't see us in broad daylight!'

'Oh, goodness!' gasped Marty Jr. 'Good thinking, Harmony! I didn't even think of that.'

'Well, now is a good time as any to get rolling,' remarked Harmony. Then, Harmony set the destination location, piloted the DeLorean into the sky, and accelerated the speed to 88 miles an hour - then the DeLorean broke the time barrier.
