Family Guy: Back to the Multiverse

Family Guy: Back to the Multiverse — Brian and Stewie are spending time at home when Bertram appears out of nowhere in a flash of light. Stewie is shocked by this, as he killed Bertram in the past. Bertram responds by explaining that he is from another reality where Stewie never killed him, and expresses disgust that a universe exists without him. Bertram then exclaims that because of this, he will gather an army from all the depths of the Multiverse and use it to completely destroy Stewie's universe. After Bertram uses his remote to leave their kingdom, Stewie takes out his own Multiverse remote and declares that he and Brian will stop Bertram at any cost. They then leave their world and try to track down Bertram, but along the way they are forced to face his army.
