Revenge of the Fallen
Galloway was extremely critical and ungrateful to Optimus Prime. He believed that not even the Autobots' victories over stopping the Decepticons can make up for the damage done to cities, such as in Shanghai, China. Galloway believes he knows what he should do, but is clearly just an idiot. Galloway believes that the Decepticons are still on Earth to get revenge on the Autobots, but the main reason was they want to destroy the Sun for Energon because the Earth is the location of the Sun Harvester. The Fallen was stated to rise by the enormous Decepticon Demolishor who is responsible for major destruction in Shanghai, China, who said, The Fallen shall rise again.
Galloway returns again, and doesn't care that Optimus Prime was killed by Megatron. Galloway only responds, Take that pile of scrap metal back to Diego Garcia and pulls off Major Lennox's ranks, forcing the NEST team to obey whatever Galloway says while bossing around the Autobots Ironhide, Ratchet, Sideswipe, and Jolt cruelly. Autobot Ratchet, who only has 3 lines of dialogue in the movies, mildly complained "This fool is terribly misinformed". Because of Galloway's decisions and desires, Ratchet insisted that the Autobots leave Earth, but Ironhide stated that before Optimus died, he stated that he wants the Autobots to remain on Earth during the conversation between Galloway and Optimus. Epps admits how much he hates Galloway, calling him an asshole.
Galloway is only seen afterwards when he was extremely nervous when being forced to jump out of a plane. Because he never experienced air-diving before, he was clueless on how to do so. Despite Major Lennox's clear instructions, Galloway pulled his blue chord right away and Lennox shouted, "NOT NOW!! We're on the plane you dumbass!", and then Galloway screamed being pulled into the ground in Cairo, Egypt.
The U.S. Military was proud and relieved that Galloway has been cut-off connection, leaving him stranded behind on Cairo, Egypt. While this is tragic for him, no one else cared.
In the prequel comics for Transformers Dark of the Moon, Galloway was killed by Shockwave after trying to show his authority.
