A Reaper swooped down as all six of them ducked. It turned around and screeched. More Reapers swarmed out of the portal to wreak havoc on 17th century Heathrow. The 10th Doctor took out the sonic screwdriver and aimed it at the portal, but the sonic screwdriver wouldn't affect the portal. The sonic screwdriver kept on buzzing but didn't do anything to the portal. The small gadget was fighting with all its might but still nothing happened. Sonic waves filled the air and invaded the ears of the humans, causing them to fall to the ground. But both the Doctors were still standing. The sonic screwdriver was going out of control, sparks flew as it overloaded. But then, a strange thing happened. The tip, which was usually blue, turned red and a burst of red energy blasted from the tip of the screwdriver to the portal. The portal folded in on itself and vanished.

"Red setting! Now that is cool!" said The 10th Doctor, pleased with himself for finding this hidden setting.

"This is hardly the best time, is it? There will be another fleet of them coming soon and we haven't even finished this one off!" said The 5th Doctor, as the other Doctor snapped out of his dreamscape and aimed the screwdriver at one of the Reapers. The energy pulsed from sonic screwdriver and poured through the Reapers body. It screamed as its body mutated and reformed, it was mutating.

It grew arms and legs. It hunched its back as its wings grew larger. Its mouth moved up to its newly grown distorted head as it grew muscles. Once its different body parts had stopped rearranging themselves, the red-eyed creature gazed into The 10th Doctor's eyes.

"Hello, Doctor. I am a Sonovore. I am a mutated Chronovore, a mixture of Chronovornian genetic DNA particles and ultra-sonic wave cells. Your sonic device is useless against me for I have all its properties! I can open doors, cut through objects I even have the red setting, so I can wipe all of you from existence!" croaked the deformed creature through its round, sharp toothed mouth. But then, Adric stood up and the creatures head sharply turned.

"You can't do this, you don't have the right to change time you messed up freak!" shouted Adric. You could hear the fear in his voice; he had never seen anything like this.

"Actually, I do have the right to change time, but you puny humanoids don't so I suggest you move out of my way or you will die a pain filled death. But you now, I might just kill you any way." said the Sonovore as it screeched and red energy poured from its hand and hit Adric square in the chest. Both Doctors tried to save him but they didn't get there in time. The energy absorbed Adric's body as the energy was sucked back through his hand and into his body. He was absorbing Adric's thoughts and memories, they were becoming his own. His distorted body reformed again, he became Adric. His eyes glowed red as he strolled towards the group of Reapers and started to screech, they moved towards The Doctors as the Sonovore itself leaped onto a nearby building. The Reapers went in for the attack; The 10th Doctor had the sonic screwdriver on red setting, ready for battle. It was six on six, a fair fight. The battle commenced.
