Sadly, I don't own Doctor Who or Back to the Future. Certainly a shame since I could the money.

Chrononexus-3000.
By TimeTraveller-1900.
The body of the missing Professor Philips was a horrific sight, as the Doctor stared down at the body after he had picked up the key to the Master's TARDIS, he took in the visible signs of what the Master's hypnotism could do to a person. The man's body was badly burnt thanks to the Sontaran Fragmentation grenade he'd let off despite the scientist's desperate attempts with the Doctor's coaxing to resist the Master's control of him. But the Master's hypnotic ability was too strong for Philips to resist; he had been given strong orders by the Master to kill the Doctor and Jo, and while he had struggled to resist, the control was too strong. The confusion in his mind had shaken Philip's survival instinct, and he had gotten caught up in the blast of the grenade.
After giving Philips a last sorrowful look, the Doctor turned away and went back to the horsebox disguise of the Master's TARDIS. He ran his long fingers over the body, feeling the tingle of chameleonic shielding right underneath. The Doctor felt a rush of jealous envy. It had been a very long time since he had seen or been inside a TARDIS with a working chameleon circuit. It had been a long time since he had ever been inside a working TARDIS, not one on which the Time Lords had placed an inhibitor on.
The Doctor gently pushed the key into the lock.
"What are you doing?" Jo asked.
The Doctor turned to face her briefly. "Shan't be a moment," he replied.
He was telling the truth. When he had seen the Master's TARDIS, effortlessly seeing through the disguise of the shell of the time machine, the Doctor had come up with two plans. Neither would really take him long to put into effect.
Walking into the horse box after closing the door, the Doctor stood in the middle of the console room of the Master's TARDIS. A slightly more advanced model to his own, of course - the Master's childish need to get one over on the Doctor was so pathetic, the Doctor really did not understand the point - and a less advanced model than the Mark 4 the Monk favoured.
The Doctor walked to the console and delicately pressed one of the controls to see if the Master had activated the defence mechanism and he was relieved that he hadn't. Slowly, the Doctor set the controls to the 51st century, and he activated the spatial circuits to create a slight displacement so Jo and anybody else outside the ship wouldn't notice anything amiss. And he set the controls to silent.
Once he was done, the Doctor activated the drive units. Listening to the heartbreaking sound of the rise of power was overpowering for the Doctor after not hearing it in his own TARDIS for so long.
Right now he had a job to do.

"Come on! Spread out!" Rossini's calls were making Jo literally jump on the balls of her feet impatiently as she waited for the Doctor to come out of the horse box. "They can't have gone far!"
Jo's eyes widened in horror and fear when she saw the distant, flamboyantly dressed form of Rossini marshalling his men. She banged on the horse box - she had thought for a moment it had been there, and yet it hadn't been there, but she had thought the heat and the adrenaline were getting to her.
"Hurry, Doctor," Jo banged on the door of the horse box, wondering what was so special about it. But Jo was much more terrified of the mob she could see coming towards them; she was good at martial arts, but there were so many of them, and she could see some of them were carrying heavy wrenches and heaven alone knew what else.
Jo was just confused; she had always known circus folk being friendly and cheerful whenever she had seen them as a child, so she was having an extremely hard time believing these people worked in an actual circus. They were simply too hostile and violent, and from what she could tell of their body language and the way held onto those tools, they looked violent enough to smash her and the Doctor to death.
Fortunately for her state of mind, the Doctor jumped out of the horse box.
"Well, that didn't take long, did it?" The Doctor asked her cheerfully as he held up a strange electrical component Jo barely glanced at. It was clear he hadn't noticed the mob coming towards them.
But even as the Doctor and Jo confronted them, the Doctor wore a smile on his face despite the pain he was in.
He had won.

As the Doctor parked his beloved roadster Bessie at the cottage he had purchased a few months ago with his UNIT salary, he reflected on the last few days. The return of the Nestene Consciousness and the sudden reappearance of the Master had been a surprise, and he was just relieved that after the long days of the exhaustive and frustrating lack of progress in finding out what the Master was planning was over. He had to admit, the Master was clever when he had thought up the plastic daffodil plan, although he knew the Master would have needed to kill several people, like Rex Farrell's unfortunate father, who was throttled by that disgusting doll to refine the idea until he had a small, simple solution; a piece of plastic film shot from the bulb of the plastic daffodil, covering the mouth and the nose creating a vacuum and suffocating the victim.
As the Doctor had said to the other Time Lord, 'vicious, complicated and inefficient.'
But it was also terrifyingly effective. And the Master knew it. But the whole plan had been clumsy, hundreds of people had been killed by daffodils which prematurely activated by stray radio signals; you would think a genius like the Master, who'd achieved a record-breaking score in his final exams at the Prydonian Academy would have anticipated such a fault, but no. Inefficient.
The Doctor shrugged his shoulders and opened up the garage door. Like his UNIT laboratory, the garage was filled with custom-made appliances to make Bessie more efficient than the most advanced sports car on the planet. But the garage was large and it was big enough to house two vehicles. One of the spaces was already taken with a different car. A midnight blue car looked more like a model of car which would not be seen in the country until the 21st century, but then it was designed like that.
But the car was more than a car.
The Chrononexus 3000.
When the Doctor got access to the Master's TARDIS, the Doctor had considered simply getting hold of a vortex manipulator, and while he had he hadn't been able to resist the urge to steal a Chrononexus 3000. Built after being inspired by the Back to the Future films, the Chrononexus was a few steps up from a vortex manipulator. His time with Bessie had given him a fascination with vintage cars and the like, but while the time travelling car was beautiful and rather flashy, he had thought about the technology behind it. It was better shielded than a vortex manipulator and possessed a greater range, but best of all, the sometimes dizzying feeling of being thrown about and being deposited in a destination era without collapsing to the ground was no longer a factor.
The Doctor rubbed his hands together in glee and he pulled out the keys from his pocket. The keys would need to be coded to his metabolism so nobody could steal them from him. The car door opened and he got in.
It was a testament to the thinking process of the designers of this time machine that nobody would ever imagine this vehicle was even capable of time travel at all, but the Doctor pressed a control to the side of the steering wheel and the speed and rev dials revealed they were actually a yearometer and a spatial meter. To the side, right above the holonet projector disguised as a vintage and retro 21st-century radio, was the destination programmer.
The Doctor started the time vehicle and he slowly drove it out of the garage. The time machine purred and thrummed under the power of its fusion core while the chronplasmic reactors booted up. Once he had shut the garage doors, the Doctor set the controls to random.
There was a flash of light and the Chrononexus 3000 disappeared. The time machine was not as complicated as a TARDIS, so it arrived really quickly. He had set the controls to random, and when he took stock of where he was, the Doctor saw he was nowhere near the 20h century, and since he'd set the controls to random, he didn't know where he was, but there was a whole army of Daleks for him to defeat….

Once he had defeated the Dalek invasion - it was relatively easy, the Daleks had come to the planet to plant a hyper gate in the solar system of the planet. But once he had teleported up to the command ship and he had gotten hold of a Dalek casing, he had uploaded a nasty virus into the Pathweb once he'd gotten access to the casing - the Doctor resumed his travels in time and space again.
As he went along to different places and times, the Doctor became better skilled at handling the Chrononexus 3000; just like he had when he had been learning how to control a TARDIS, and just because he had failed didn't mean he hadn't picked up a few skills, it was just a matter of controlling the time vehicle.
According to the Chrononexus 3000's internal chronometers, the Doctor had travelled for over 4 months before he had realised he had to return to UNIT HQ to see what was going on with the Master. On top of that, he was finding himself missing the Brigadier and Benton and Mike, and the others. But he also needed to find out what was happening.
Setting the Chrononexus 3000 to the date and time he had left originally, the Doctor returned. In between the different weeks, he was facing some calamity involving the Master, the Axons, the Daleks, the Daemons, and the varied missions from the Time Lords, the Doctor would always return to the Chrononexus 3000 and go away for months, or even years at a time.
The Doctor had learnt his lessons from the first time around. He would always prepare for the trips and he would ensure he had the vortex manipulator on him at all times in case anything went wrong. The Doctor was conscientious to hide his time travelling from not only UNIT but from the Time Lords as well.
But for now, the Doctor would enjoy some of his freedom.
