The Doctor was quiet for a moment. His gaze lingered on Robin's until eventually a smile spread across his lips. Even in a hopeless situation, she still had faith. He couldn't let that go to waste. "I'm going to get you out of here," the Doctor said before reaching into his pocket and pulling out the slingshot he had used against Davros. He armed it with a small blue pebble that he pulled out of his top coat pocket and pulled it back before aiming at the Cybermen. "I'm going to use this to draw their fire, once they're locked on me I want you to kick open the door and jump to the ground. When you hear the firing stop, run like the wind."
Once the Doctor was finished he pulled back the pebble and fired it at the Cybermen. It struck one of the metal men on the head, directing its attention towards him. For a moment it stared vacantly at him, as if unsure whether the blond surfer in the duffle coat had just done something so mad as attract its attention.
"Okay, run Robin! Go now! Go now!" The Doctor yelled before pushing her out of the van and sliding into the drivers seat. He pushed down on the gas and the van sprung to life, tearing across the street towards the metal soldiers that blasted wildly at the approaching battering ram on wheels.
"Okay, time to see if I can still drive," the Doctor murmured before pulling hard on the steering wheel. The van swerved violently to the right as it approached the Cybermen, picking up speed as it turned on its wheels. If it hit them whilst turning it would more than likely knock them down like a bowling pins.
Except, that didn't happen. For the Doctor had missed the Cybermen completely and accidentally parked in front of them. His face turned red as he looked at them blankly, they too seemed to stare back with their empty sockets, as if unsure when the Doctor's ingenious plan would commence.
"Okay, so that settles it. I can't drive," he said before the Cybermen raised their weapons to point at his head. "I can do this thought," he spoke before pushing the sonic screwdriver against the van's radio. It let out a horrific shriek, causing the Cybermen to falter and clutch their head in between their metal hands as the signal screwed with their sensors.
"RUN ROBIN! RUN NOW! DON'T LOOK BACK!" The Doctor yelled. He knew that it was unlikely that he would survive, the van was too much of a target, if the Sontarans or the Rutans hit the engine he would go up in flames, but that didn't matter, the explosion would distract the armies and Robin would escape. That would be victory enough for him.
The only problem with that plan was that the Sontarans and the Rutans had ceased firing at the Doctor and each other, for they were far too busy trying not to be run down by the huge armored black van with the mechanical dog riding on top of it.
The Doctor stared abashed at the scene as the van drew closer. The Sontarans were yelling commands at each other as the van raced past them and parked in the middle of the chaos.
"Targets not retreating. Continuing fire," the electronic, seemingly innocent voice of the dog spoke as it blasted at the aliens with red laser blasts which burned holes into the armor of the Sontarans and seemed to irritate the gelatinous forms of the Rutans. Soon, both armies began to disperse, figuring that the psychotic disco robot dog was a foe that would require some thought.
"I love that dog," the Doctor whispered as the metal dog ceased firing at its enemies. "I love that dog so much that I want to marry it," he said before beaming brightly. He bolted from the van, releasing the pressure on the radio and freeing the Cybermen from their torment as he ran across the road.
"Robin! My plan worked! K-9 is here to save us! Just like I planned!" The Doctor called with a mad laugh.
