Jet Alone (ジェット・アローン) is a bipedal robot developed by Japan Heavy Chemical Industries, designed to replace the Evangelions. Unlike the Evangelions, which have a limited internal power supply and must rely on external power cables for extended operation, Jet Alone has an internal nuclear reactor (likely a pressurized water reactor) and can function for at least 150 consecutive days. Jet Alone requires no pilot, and is controlled by an onboard computer. Radio commands can be issued from a ground station. Being a robot and not a living being, Jet Alone cannot generate an A.T. Field. Shiro Tokita pushes aside the issue, describing the creation of an (artificial) A.T. Field as "only a matter of time."
