Forward into the past
I.
Present day, 2014
The Doctor set the spacial and temporal coordinates for his desired destination into the Tardis navigational computer and activated the main drive. The damping cylinder in the center of the octagonal main control panel began to rise and fall as it modulated the time flux driving the Tardis though the space time continuum. A yellow warning light began to glow on the panel, which attracted the doctor's attention.
Looks like you've developed a bit of a kronotron leak, old girl. the doctor muttered to himself. Well, it doesn't look too serious, and we will be safely at our destination before the matter goes critical. I can repair the problem once we are back on terrafirma.
The Tardis passed over Japan as it drifted backwards in time between 2014 and 2002 AD. The kronotron leak increased causing the time warp field around the time-ship to grow in size, reaching several hundred feet in diameter. Just large enough to catch an innocent bystander who happened to be flying too close to the cloaked Tardis and drag him along for a ride though time.
Astro left the Ministry of Science for the day, heading back home. It had been a rather busy day working with Professor Ochanomizu on the robot spaceship project, and there had been plenty of glitches. Maybe tomorrow all the issues would be resolved and they could actually get the ship into orbit. Only a few city blocks from the Institute, he suddenly had a queasy feeling feeling nearly cause him to blank out. His vision started to blur and there was a loud buzzing in his ears. The disorientation didn't last very long, and he quickly recovered his equilibrium.
As his vision cleared, Astro saw a speeding truck in the distance heading almost out of control on the main street that ran parallel to the Ministry's main building. Heading away from the building on a path that would intersect with that of the truck was a young boy on a scooter. Astro's electronic brain quickly analyzed the the speed and direction of both vehicles, and saw that they were on a collision course with each other. Neither driver would be aware of the danger until it would be too late.
Astro didn't hesitate, he quickly swooped down from his position above the street, and zoomed down to yank the boy from the scooter just a fraction of a second before the truck slammed into it. Astro set the child down only a few yards from the wreck.
You're lucky I was flying by, he told the boy, one second later, and you'd have been killed!
Gee, thanks! the lad said as the two of them laid eyes on each other for the first time.
Astro was taken back by the boy's appearance, he looked almost exactly like his own twin, except for having dark brown hair instead of Astro's black. Both had the same pointy lock's of cowlick hair, though Astro's exaggerated the pointedness.
I'd better go back to my dad and apologize for running off, the boy said as he carefully crossed the street and ran back to the Ministry.
Astro tried to shake of the strange feeling he was getting after that incident. He took off and continued on his way back home. When Astro arrived at the address of his house he received his second shock of the afternoon, for his home was gone! There was a vacant lot where the house should have stood.
Now what's going on? Astro wondered. He brought up his heads up display and checked the GPS coordinates of his current location. There was no doubt, he was exactly on the site where his home should have been, but it was not there!
Tobio walked back to the Ministry of Science and entered the main lobby. He took the elevator up to the top floor and entered the reception area of his father's office. He waved to Dr. Tenma's secretary who buzzed him through the door to the inner office. Umataro got up from his desk when he saw his son enter the office.
Dad! the boy yelled out. I'm so sorry that I ran off!
I forgive you Tobio, can you forgive me for my outburst earlier? Tenma asked.
Yes, I forgive you! The boy cried out as he ran toward his father to hug him. After a few moments he backed away from his dad and looked down at his feet.
I had a little accident a little while ago, he said in a low voice. I was almost hit by a runaway truck on my scooter and some flying robot grabbed me out of the way just in time. I had to walk back here, the scooter was demolished.
Dr. Tenma then turned toward his son. Tobio, I warned you to be careful driving that scooter. Don't expect me to replace it until you've shown me that you will be more careful, next time you might not be so lucky.
Yes, Dad. Tobio said.
With that Tenma and Tobio walked out of the office and took the elevator down to the garage level where Dr. Tenma's car was parked.
Astro flew to the Ministry of Science building and took the elevator to the top floor. Maybe Professor Ochanomizu can figure this out! he thought to himself. When he got to the professor's office, he saw that Ochanomizu's name was not on the door. The name engraved on the outer door was that of Dr. Umataro Tenma. This only made Astro even more confused. He entered the office lobby and looked at the secretary's desk.
If you're looking for Dr. Tenma, you just missed him. She said. You can come back in the morning.
Astro saw the date on the calendar on her desk, it read April 1, 2002. I'll come back tomorrow then. he said walking out of the office. He was really confused now, if the calendar was correct, he'd somehow gone back in time about 12 years!
Note that I've used the originally accepted date of April 7, 2003 for Astro's birth date in this story. Keep that in mind as the events unfold. And yes, this story is based on a 1985 sci-fi movie you might be familiar with.
