The conclusion to the war against Dracula was one that the vampires never expected.
The ground troops had won decisively on the werewolf capital as without the help of Dracula, the rest of the troops did not have the necessary strength to repel the modern vampires who had greater numbers and tactical superiority.
For a moment it looked like the vampire forces had managed to snatch an unlikely victory when the times were tough for them as a species, however, just then Drax landed on the werewolf capital with an unconscious Max in his hands.
Since after Drax took over Dracula's body, the primordial vampire no longer looked like his usual being with blood red eyes or a sleek chiselled chin, but rather like an old man with a thick beard and grey eyes, nobody made the connection that Drax was actually Dracula, however, they did assume the worst seeing Max unconscious.
