Jason is arrested for stealing secret plans and G-Force is grounded. Jason sneaks out of his jail cell to confront Garth, the man who accused him. Garth, who is really Ivar the Cunning in disguise, stuns 7-Zark-7 and tells Zoltar to begin the invasion. Garth is caught and is shown to actually be Ivar. Zoltar sends a colony of mechanical ants to attack earth, but G-Force transmutes Phoenix into the Firebird and melts the ants, stopping the invasion.
