"How do we know you won't one day act against America's interests?" - Swanwick to Kal-El
Lieutenant General Swanwick is an officer in the United States Army. He is the head of United States Northern Command, an organization sworn to deter, prevent, and defeat threats and aggression aimed at the United States.
"I'm just speculating, but I think whoever's at the helm of that ship is looking to make a dramatic entrance" — Swanwick to Dr Hamilton
General Swanwick was alerted to the mission control room at Peterson Air Force Base when an unidentified object settled into orbit near Earth. Shortly afterwards a message was sent across the Earth in search of Kal-El from General Zod.
Kal-El arrived at the base shortly afterwards surrendering if Lois Lane was freed. Kal-El and Lois sat in an interrogation room where the General questioned Kal-El on his motives before handing him over to Zod's Commander Faora Hu-Ul who requested that Lois come too.
When 2 bogies descended from the craft into Earth's atmosphere, Swanwick order the strike to take them out, led by Colonel Hardy.
After the Battle of Smallville, Kal-El and Lois came along with Kal-El's Spaceship telling the General how to send Zod and his followers back to the Phantom Zone. Swanwick agreed and ordered the attack.
After Zod and his troops were defeated in Metropolis, he had a drone try to track Kal-El's whereabouts to find his address. Whilst being driven out of Peterson, Kal-El threw the drone in front of his car telling him to stop spying on him and that he is not a threat to America.
- At the San Diego Comic Con International 2013, Harry Lennix was bought up on stage by Zack Snyder to read a quote from The Dark Knight Returns (the famous "I want you to remember the one man who beat you" speech) as a logo appeared on-screen, merging the Superman and Batman symbols, thus announcing the Man of Steel sequel to be the very first Superman/Batman film.
