The heroes of "Base Amerika Earth" are Captain U.S.A. and his loyal Z-Force warriors, JoBat, his First Officer and Viona-V his Medical Officer. He also has two posatronic androids, Aurora Girl and Jontu, which were created by his father to serve mankind. The Captain and his two human Z-Force warriors are from a galaxy that exists in another dimension and time. Their worlds and civilizations are far more advanced than those here on earth for they have conquered space travel.

The Captain and his warriors left their worlds in pursuit of his nemesis, Admiral Doom, who escaped in a stolen spacecraft from a penal colony in their galaxy. In pursuit of Admiral Doom they entered earth's galaxy, as did Admiral Doom, through a wormhole opening. As they entered earth's solar system they encountered a fierce and deadly meteorite storm that damaged their spacecraft's outer force field shields. Unbeknownst to our warriors a few meteorites penetrated the Starship's outer hull and inflicted heavy damage to their guidance and propulsion control systems. Unfortunately, due to these penetrations, as they approached earth in search of Admiral Doom's landing site, they lost control of their Starship and crash landed in a remote and isolated area of America's Dakota Black Hills. They crash landed in earth year 2002, a few months after the horrendous 9/11 attack on America by terrorists.

Captain U.S.A. and his warriors came to earth at a time when America needed help to fight terrorism. He and his warriors jointed forces with America's President, George W. Crusher, and his new Sentinel Force Commander, General Tommy Strikeagle, to fight and defeat the terrorism now on earth and hopefully capture his nemesis, Admiral Doom, who landed on earth as well. In their quest and struggles to capture Admiral Doom and defeat terrorism the Captain and the President, through a divine vision learn of earth's creation engine, the Rotunda Well Sanctuary which contains the sacred Genesis creation scrolls of all life in the universe.
