Then the Avengers invade the White House itself and locate the device which can return them to their own world. The Beast, disguised as the President, keeps the Squadron occupied, while forcing them to face the fact that their world has been taken over and that, by never questioning their elected officials and corporate leaders, they have been aiding the enemy.
