...Almost two years since my last entry, and finally the 15th chapter is here... Better late than never! Hope you all enjoy! This one is more about the Doctor explaining his back-story to KP and Ron. Hopefully will get another chapter done in the next month (maybe...).

Time Sitch

A Kim Possible/Doctor Who crossover

Time Sitch - chapter 15

My name is the Doctor. I'm a Time Lord, who is over 900 years old. And I travel though time and space in my ship, called the 'TARDIS'; stopping here, there, and everywhere to help people in need…

Some people would say I'm the saviour of the universe. Other beings have called me names such as 'The Destroyer of Worlds' and the 'Oncoming Storm'. I just hope to do the right thing, and try to stand up for what is good.

I guess that's part of the reason I go by 'the Doctor' as my name. I want to help people in danger, distress, pain, suffering… sometimes saving them from their crimes.

I was born on the planet Gallifrey, part of the constellation of Kasterborous. From space orbiting the planet, it looked as barren as any dry planet, like Mars. And it was certainly drier than Earth. But it had a certain special beauty to it. At a quick glance, the landscape would be described as 'rustic-coloured'; but there was more to it than that. Night times were especially something to behold - snow-capped mountains; fields of red grass; both against the backdrop of the orange night-time sky. And every morning, the light would catch the silver leaves on the trees - it would look like a forest on fire. Not a surprise Gallifrey was referred to as the 'Jewel', and 'the Shining World of the Seven Systems'.

The Time Lords were seen as a grand, noble group of people. They were advanced in all forms of scientific knowledge, but they were most famous for their time-travelling technology. Because of this, the Time Lords believed to have a grand duty to protect the 'sacredness' (if you want to use that word) of time travel.

Basically, they didn't want this sort of technology to get into the wrong hands. They had 'rules' over the responsibility of time travel; but even the higher-ups sometimes broke those codes for one reason or another, and would assign discreet missions to certain individuals. But overall, interfering with time in such a way that it changed the way certain events went was frowned upon, and quite often punishable.

Most Time Lords were Gallifreyan (like me), a humanoid species that on the outside looked the same in likeness to humans. However, the main difference is more internal; they have two hearts. Its purpose was to help Gallifreyans live longer. When they were very old or their body was severely damaged, they would perform a process called a 'regeneration'. This would complete a physical change, granting each Gallifreyan a new body. But at a cost - almost always, a psychological change also took place.

I've been through a fair few regeneration rounds myself. Each time I've been given a different personality. You think I've been moody on occasions? Well once upon a time, I was always seen as a grumpy, old grandpa!

Regeneration seems to be like a 'useful tool'. And in some ways it is, if you want to physically stay alive. But each time you regenerate, it feels as though your present persona dies; fading away into the depths of time. I personally have found it harder every time to let go of my old personalities. Maybe it's partly due to how limited even a Time Lord's life can feel. Perhaps I've just loved my current self so much… no matter how much I say, 'I don't want to go', this individual persona will have to do so one day.

The Master and I have known each other for a long time. We first met when we both started at the Time Lord Academy, at the age of 8. For our whole childhood and academy years, we were close friends. We had so much in common. We both had similar backgrounds and heritage. Both of us very clever academically… and incredibly handsome young lads, of course. We even made a pact, me and him. Every star in the universe, we were going to see them all. But in time, he became too busy burning them.

The warning signs were evident right back at the beginning. Every child had an initiation ceremony when joining the Academy. We were no exception. One of the things children had to do in these ceremonies was look into the Untempered Schism; a natural opening in the space-time continuum, a gap in the fabric of reality from which could be seen the whole of the Vortex. It was a painful and terrifying experience. Each child reacted differently. Some would be inspired, some would run away, and some would go mad. I was the one that ran away. The Master was the one that went mad.

When the Master stared into the Time Vortex through the Schism, he saw the raw power of time and space. That was when the Master first saw eternity. Some would say that's where it all began, down the path of madness, insanity, and craving for power.

As for me, like I already said, I eventually ran away. I stowed away on a TARDIS - the one I've always travelled in - and left Gallifrey. Why did I run away? I guess it was a mixture of things: boredom; being scared; or just wanting to see the wonders of the universe. There seems to be many reasons; but each of my incarnations has mixed up the events more and more each time. In any case, no matter why I started travelling, I managed to find myself in sticky situations, helping other people and creatures, whether I intended to or not.

Over time, saving the universe became the main thing for me in my travels. I would have companions travelling with me, going on daring adventures through time and space; exploring different worlds, only to find a threat and having to solve the problem. I did lose a few close friends; but for many years, I felt like the cheeky Time Lord who kept running away from his 'bosses' back on his homeworld. Nothing could stop the fun I was having…

And then came the Last Great Time War. It was the biggest war to have ever taken place in the whole of the universe, and the whole of time itself. The two most powerful races - the Time Lords themselves, versus our archenemies, the Daleks - fought against each other for an eternity, using countless time periods as their battlegrounds. We fought the Daleks for the sake of all creation. And they lost. We also lost. Everyone lost.

The worst thing about it all: I ended the war. I killed all the Daleks, and all the Time Lords, because of the terrifying threat the war was to the whole of the universe and all of time. It could have been the end of everything. I used 'the Moment' - which others called the Galaxy Eater - to time-lock the war, so no other life would be affected, and destroyed Gallifrey and the whole Dalek race. Now I have the blood of billions of lives on my hands, and everyone across the universe hasn't failed to tell or taunt me that I'm the last of my kind.

I thought I was the only survivor of the Time War. I was wrong. Two things got out alive.

The Daleks were one of them. Originally, only a smattering of them. But they soon rebuilt themselves and assembled new armies, and had plans once more to become the ultimate rulers of the universe. Each and every time I've had to stop them, on my own. And every time, the Daleks would run away and have new ways of returning. Over time it has taken a toll on me, and I've had to stop myself stepping perilously close to the warrior I was in the Time War.

And the other thing - someone - to escape the Time War, was the Master. The first time I saw him after the war, he was using the Chameleon Arch - which was a piece of Time Lord technology that looked like a fob watch - to biologically 'disguise' himself as a human, and make himself temporarily forget about his previous life.

I met him right before the end of time itself; he was calling himself Yana, and 'helping' the last humans to escape to a plant called Utopia. But something clicked in his mind; he opened the fob watch, and all his memories and biological make-up as 'the Master' returned. He escaped to the present day, and impersonated as a Prime Minister called Harold Saxon, meticulously setting his plan in motion, before using the Toclafane - who were the last form of humans, after they had been tricked to travelling to 'Utopia' - to conquer Earth. It took a year, but after a long, hard-fought battle - having to suffer pain as well as patience - I and my companions unravelled the Master's destructive plans.

And then one final event took place; the Master's wife killed him. I witnessed first-hand as she shot him. I was caught off-guard, but perhaps he had seen it coming…

I was going to have the Master under custody in my TARDIS, to protect the universe from the madman. But I guess I also wanted to protect him; I wasn't the last of the Time Lords after all, now knowing that my former friend was still alive. And yet, there he was, dying in my arms, because of the traumatization his wife had been through, therefore taking revenge on the Master because of his abuse to her.

I pleaded to my old friend to regenerate. Reminding him of the good times we had as young Gallifreyans. But he refused; he had become so disillusioned from me stopping him in his all his schemes that the last thing he wanted was to be imprisoned by me. He refused to regenerate.

He died in my arms. Once more, I was the last of the Time Lords.

Or at least until now. I don't know how the Master was resurrected. It should be impossible; I cremated his body. But it's happened; he - or now she - has returned. Perhaps I won't know until later in my future.

My future itself is counting down at the moment. I know I've already said I'm the one that has been running. But I've been doing more of that recently. I think fate is catching up to me. I remember someone giving me a prophecy about my future not too long ago: "Your song is ending sir... It is returning. It is returning through the dark and then Doctor, oh, but then... He will knock four times."

There have been other hints that my time is running out. Just before I tumbled into this reality, I saved people from a viral species, on Mars in 2059. The thing was, everyone on that base should have died. Out of my arrogance, and having travelled around for so long knowing I was the last of the Time Lords, I thought I could break the Laws of Time. I called myself the 'Time Lord Victorious', thinking no one else had the authority to stop me. But the captain of the base saw through my arrogance - without her death, her granddaughter wouldn't be inspired to follow in her grandmother's footsteps to explore the depths of space. So after I had taken her home, she took her own life. I realised that I had gone too far, and that it wasn't my task to change history for my own gain.

I seethed within myself with self-hatred, feeling grief and anguish. And to add to that, I had a vision soon after of someone else, who had also told me very recently that 'my song must end'. I felt fear, and perhaps for the first time was truly scared. So, in an act of defiance, in the face of my fate, I decided to run away faster than I had ever done before.

And that's when I arrived here. In little ol' Middleton. In a reality not of my own; not even an alternate universe.

I'm gonna be honest; you three (yes, you too Rufus) are all braver than me. Here's this 906 year old alien, who has faced the most dangerous creatures in his universe; and here I am now running away from the common enemy - death. But you lot were ready to face up to 50+ unknown killers - who I don't even know how powerful they are - ready to take them down to try to continue protecting the city and its civilians. Or perhaps you were ready to fight more out of vengeance? Either way, you were all ready to face death head on.

I know I just said that what Missy did was out of my control. But it's true that she is my responsibility. That hasn't changed since she was 'Harold Saxon', Prime Minister of the United Kingdom. I promise; I will stop Missy and her madness, and sort out this chaos. I will not let you down again.

Just promise me one thing: keep your youthfulness. Hang onto it for as long as is possible for a human being. It's what has stopped fear from overtaking you, and I don't want you to stumble now.

You're the bravest kids I've ever met; and being brave is one of the most important attributes in life. Of course, it would be suicidal to face the enemy without your set of skills, but my point still stands. You've reminded me what real heroes are made of.

All I have left to say is this… I'm just a madman who wants to help people, no matter how many or how dangerous. I'm going to help you save this planet with every possible breath I have. And, in this moment, I will stop running, and face my fears.

Kim and Ron stared at the Doctor in awe, after he finished telling his story. They weren't sure if he now looked a little aged in his eyes after that tale, but they could also sense a dogged determinedness from his current outlooking persona. And Kim and Ron now felt a lot less uncertain about the Doctor's intentions; they knew he truly wanted to do right by them and the world they knew.

The Doctor now sat silently, just looking slightly downwards. Kim gently placed her right hand on top of the Doctor's own hands, which were now clasped together on the table. As the Doctor lifted his head towards Kim, she gave a quiet response to the Doctor's story; "Thank you, Doctor."

The Doctor acknowledged the gratitude from Kim, with a sense of appreciation from himself for her acceptance of his tale. Recent events – in his own reality and in Kim's/Ron's reality – had weighed heavy on his heart. So it felt good to lift a little bit of burden off his shoulders.

Ron breathed out heavily, looking at Rufus who was also doing the same; the Doctor's story was a lot to take in. Not that they had a lot of time to ponder on it; there was still the matter of trying to take back control of their world, in some way.

"So, whatever Missy did to our world", Ron started, looking at Kim, "we need to sort out", he finished saying, also addressing to the Doctor.

"Yes", the Time Lord said, "we better get cracking."

"So, if I remember correctly, there was something about a dimension-reality-thingy when we last saw Missy", Kim stated.

"Yes", the Doctor acknowledged. "With that, and the vortex manipulator that she threw into the middle of the energy matter created by the Hand of Omega, I think it might have something to do with this world's current situation."

"So we might be able to reverse it?" Ron exclaimed hopefully.

"If we find a way, yes", the Doctor said. "But I don't think it's that simple. If I even had access to my TARDIS, I don't have a vortex manipulator myself: hate the things. But whatever Missy did, I suspect this current reality wasn't just created out of pure madness…"

"Missy has a plan. But what's her end goal?" Kim asked openly, in a slightly confused manner.

"Yeah, I'm not quite seeing why Missy would want to take over our world if she is simultaneously bringing it to complete ruins", said Ron.

"That would have been Dr. Drakken's plan", the Doctor stated. "Which Missy steered away from…" The Doctor took a breath, and then a realisation came to him; "Perhaps Missy's testing me."

"What do you mean?" Kim asked.

"Well she might be executing madness, but it's pre-determined madness", the Doctor said. "Even though she's being maniacal, this is perhaps a crazy way of hers to push my abilities and breaking point. The Master; in a never ending battle to test me; a war of minds, throughout all time.

"And how could Missy come up with a world like this, if not done out of uncontrolled madness?" Kim questioned.

"I'm not exactly sure", the Doctor replied. "But this world's current reality must have been manipulated by her in some form, and not by machinery. None of the technology she used would be able to manipulate a world into this specific image."

"Are you suggesting that she might have used her mind?" Ron said.

"Perhaps. Not that I can be sure on that either. Why does nothing simple come to mind in situations like this…" The Doctor looked in all directions as if he were trying to find inspiration, but it was just a distraction for him to get a few extra seconds of thinking time. Finally, he looked to Kim and Ron, stating, "I think the only way we have a chance of fixing any of this, either way, is by going to Drakken's lair."

"We've got nothing left to lose", Ron said, more as a throw-away line, but certainly knowing there wasn't any other real option.

Rufus sensed the time for the group to make their next move, and so jumped onto Ron's shoulder. The other three left their booth and stood facing each other. "However we do it, let's sort this sitch out", Kim declared, looking in that moment the most assertive and determined out of everyone in the diner.

The Doctor raised an eyebrow and nodded in respected acknowledgment. "Lead the way, Miss Possible", the Doctor said. With that, they left the Bueno Nacho restaurant, and set towards Drakken's hideout.
