The first unit produced by the Super Dimensional Guard's top secret Gundam Force program, Captain Gundam is the main defender of Neotopia. Initially secretive and rigid, Captain loosens up and becomes more human via his interactions with Shute. The core of Captain Gundam is his Soul Drive, a mysterious power source which responds to emotions of others. When cheered on by Shute, Captain can use the Soul Drive to unleash his lethal Captain Punch fist attack. While Captain's standard form keeps weapons to a minimum (vulcans, missile launchers, beam saber and an optional light beam rifle and light shield), he is designed to be adaptable for various missions.
