Two years after the defeat of Galactor and the apparent death of Condor Joe, a cruise ship is attacked by Leader X, killing nearly everyone aboard. A young girl survives the attack but is captured by X and rapidly aged into the bizarre, masculine‑voiced villainess Gel Sadra. Though she has the appearance of an adult, Gel Sadra remains prone to childish tantrums and immature behavior. With Galactor revived, the Science Ninja Team is called back into action. A shady man known as Hawk Getz is introduced as Joe’s replacement. Getz is soon revealed to be a Galactor agent in disguise, he had killed the real Getz who was scheduled to join the team, and is ultimately killed by a mysterious feather shuriken.
