All Creatures Great and Small Chapter 4

Buffy looked at her sister. 'What the hell happened to you?!?'
'The same thing that's about to happen to you. Get over here, NOW!' Dawn dove behind Xander's car firing her gun above Buffy's head. Xander didn't stop as he joined her and the other two behind the car. Buffy looked over her shoulder as she ran to them a twenty foot tall robot was bringing its rifle around. Ducked behind the car she could feel the heat from the laser blasts.
'I take it that daddy isn't happy that you three just aced his little buddies.'
'That's putting it nicely Xander. What are they doing here and why are they after you two?'
'We don't know, they just attacked. It might be some thing to do with that light show. Buffy, is it?'
'No I don't think so. Dawn what is going on?' Buffy flinched as another blast came close to hitting them.
'We are being shot at by a 18 foot tall robot from another planet. We are also hiding behind a car to stop him from hitting us. Another robot is about to smash him into pieces, watch...' Dawn pointed at the truck cab she had jumped out of. It was coming straight at them. Buffy watched as the front fell forward and a hatch opened on its' roof.
Being the slayer for the better part of six years had introduced her to a lot of strange a weird things. Never had she imagined a red truck cab change into a robot while jumping over her head. Everyone watched as it flew over them and punched the other one a good two miles away.

Dawn quietly laughed at the shape of Buffy's face. 'Thanks Prime mind giving us all a lift back to the ark.'
'Of course not Sunburst, get in' he switched back to cab mode and opened the door.
Xander finally blinked. Buffy's face twisted some more and the two cassettes just looked at them. Some what absently Xander noted that five people wouldn't fit in the cab. 'Not a problem. Boys, would you mind transforming please.' Dawn held out her hands and the two brothers shrunk as they converted back into tapes. Xander Decided at that point to faint while Buffy stared at Dawns hands and the tapes during the silent drive back to the ark.

Just passing Saturn the rouge planet passed through the outer edge of its rings. Even at this distance it's awareness scanned the surface of the third planet. The was so much life on this rock that if He was able to stop his foe He would gorge on the life energy and be, for a time, sated. If he could once again defeat his long time foe.

Xander was first of all embarrassed. He blamed it on too many shocks and the fight earlier but he still fainted when he saw two robots, Rewind and Eject, shrink into small tapes. The big red dude, Optimus prime had just finished describing Unicron. A year ago now he had "helped" stop the mad god Glory from destroying the universe. This sounded worse. One of the oldest of the old gods, not mad, not out of control, just driven to destroy existence. From Buffy's dreams and Primes description he has found a way around the prison Primus made and is coming here. The only good news was that thanks to the joining of Prime and Dawn a new God, Optimus Primus, had been born and He might have the power to stop it.
Buffy looked at Prime 'So why didn't primus just destroy Unicron in the first place?'
'The battles between the two gods were massive. It is told that whole planets were vaporised, suns were snuffed out and whole galaxies destroyed as collateral damage.' Prime was sitting at the table they were sanding on. His yellow eyes the only things moving.
'Sort of squashing on the ants when you fight over an ant hill?'
'Exactly Mr Harris. Primus imprisoned both himself and Unicron in an effort to stop the accidental destruction of those he wished to protect.'
'And now the rematch will take place on Earth! What if we become "accidentally" destroyed?'
'Miss Summers, this is not the only inhabited world. At the risk of sounding callus, if this world is destroyed to save the countless others then it is with a great sorrow that it must be sacrificed.'
Xander made a decision, one he had often wondered about 'The human race gone for the greater good. How can any one be asked to stand by and watch it happen. I agree...'
'Xander!!!'
'I haven't finished. I agree that it must be done but I can not let you fight without help. Whatever I can do to help I will.'
'You beat me to it, every thing he said goes the same for me. I was chosen to defend this world but the universe is more important. I'd like to save both if we could though'
'Alexander Harris, Buffy Summers. I once thought that humans were a simple selfish race. While Sunburst has shown me that you can be stronger than us in spirit you have shown me that your race can match us in conviction. I think I will never understand humans. If your kind is destroyed the Galaxy will lose a unique race. Unfortunately the is nothing you or anyone else can do.'
'What about this merging thing, you said that Dawn was now a part of you. Could we do the same?'
'I do not believe so. We both are vessels for trans-dimensional energy. You are not. It may be possible for you to bond with other Autobots if you want'
'That might not be a bad idea, hay Xander imagine the damage I can do to daemons with a robotic suit of armour on!'
'It could be cool, I just don't like being a battery that's all. Reminds me to much of The Matrix'
'What did you say?!?'
'Sorry big guy. Not your matrix I'm talking about the film with the leather coats and guns' Xander didn't know how "human" these Autobots were but Prime's laughter was a good sign.
'Then you might want to become a head or target-master.'
'A what and a what?' Buffy was still perfecting confused look
'A head-master is when you have the ability to become a transformer's head, while a target-master is their weapon.' Prime smiled at them. Xander wasn't sure how without a mouth he could do that but he did.

By evening Buffy and Xander had decided to become target-masters and head masters, respectively. Both their soon to be partners had already agreed and they were about to tell Dawn and Prime. Walking through the massive silent doors the saw the two watching a monitor screen the size of a house.
On it was a broadcast of live news '... just about to pass Mars. The rouge planet is said to pass close by, scientists believe that it may not hit but that the damage to our world could mean disaster. A planet almost the same size as out own is passing through our solar system, we have an image from the Hubble space telescope to show you now. My God... it's what is...'
A huge orange and yellow planet was shown. There were two huge, curved, yellow spires facing the camera. To Buffy they looked like pincers or claws. In between them was a huge crater that looked like a gaping mouth.

Prime and Dawn looked at each other. This was Unicron. The size and shape of a planet. Prime could only mutter one thing. The title of Unicron, something he had not said to his smaller friends. 'The world eater.'

Authors note OH dear this seams to be a cliff hanger Due to several points the next chapter won't be up for at least a week I think that might make me worse than Unicron oh well have fun...
