The Doctor howled with laughter, 'The God of All Daleks' indeed. The foul creature skulking in the darkness of backwater space for centuries scared, giving him threats? It didn't matter how many of them there were, all the Daleks were vermin. They were a disease, an infestation. Nothing more. Of course this is what he told their leader, the warped, twisted, deranged mutation. Did it not know who won The Time War? Of course not, it didn't make it to the end.
So The Doctor was trapped here. Trapped. Trapped by the monster. Trapped on Floor 500 of Satellite 5, one of earths most used and largest transmitters, with all the tools he needed to make the most brutal delta wave in half the galaxy. And what were The Daleks to do about it? Were they going to shoot him? Their tiny impaired mind really didn't understand true power. It was all getting a bit too much for a straight face.
Coward or killer? As if that thing had to ask. The Doctor would fry more than just the planet Earth to save his own skin and even more to defy The Daleks. But today was about winning, he wasn't about to hand out his golden trophy of first place in the universe's most horrific war.
"Killer of course, don't you know me?" The Doctor gave his famous, sly smile. That was as much of a farewell that the God of All Daleks was ever going to get as The Doctor pushed the heel of his booted foot down on the life-ending lever.
The fires roasted planet Earth for 5 days, The Doctor watched for 3.
