Lo, There Shall Come a Conqueror is the 18th micro episode of Avengers: Earth's Mightiest Heroes.
Kang the Conquerer is tracking Captain America through his battle with the Red Skull, observing Rogers. He flashes forward through various time-frames as Captain America lands in the ice water and begins to freeze. Something has destabilized Kang's future, and is eliminating his time-stream. As his future world begins to be wiped out, Kang comes to the conclusion that Captain America and his actions are responsible for the destabilizing effect. Kang orders that his fleet time-jump to the past; he will remedy the destablization of his time-line by conquering the earth of the past. His consort, Ravonna, is caught in the destablizaton effect just as Kang's flagship jumps to the past.
