General Warren R. Monger is the overarching protagonist of DreamWorks' Monsters vs. Aliens franchise. He is the man in charge of Area Fifty-Something, where the monsters were kept. The monsters attempted several escape plans to outwit the general, but never succeeded. He gave Susan Murphy (later renamed as Ginormica) a tour of the facility shortly after she was captured. Once the Robot Probe attacked Earth, he met with the US senators Margaret, Ms. Ronson, Angelina Petrova and other senators, including President Hathaway, who were previously discussing solutions to stop the aliens, to discuss his plan. On the screen in the meeting room, he displayed pictures of the monsters, which Ms. Ronson screamed at when she saw them. When he showed a film of Ginormica, the President screamed. His plan was to send the Monsters to destroy the probe. He then went back to the monster prison, and told the monsters they were getting out. He discussed what he asked of the monsters, and also added that they would be freed.
After the robot was destroyed, he took Susan and the others to her hometown, stating that he "called your family to let them know you were coming home. I also called the Modesto PD; told them not to shoot at you."
Later, when Susan was captured, he took the others up to Gallaxhar's ship, so that they could free Susan. Afterwards, he and Butterflyasurus arrived to save the monsters from the ship exploding.
Down on the ground, he said that he was so proud he could cry, "if I hadn't lost my tear ducts in the war." He then stated that a radioactively mutated snail called Esgargantua was slowly making its way towards Paris.
He claims to be 90 years old, in spite of his middle-aged appearance.
