The dramatic conclusion to 'Doctor Horrible's Sing-Along Blog' will involve Doctor Horrible gaining ultimate power, becoming a dark and vengeful god with power over space and time itself. He realizes that he is destined to travel back and found the Evil League of Evil, announcing to the defeated Captain Hammer, "I am the Bad Horse. I create myself."
