The show takes everything you loved about the original Science Ninja Team and immediately breaks it by forcing you to fight the same war twice, knowing you already lost people you can't get back. Gel Sadra is a villain designed to make you uncomfortable, a child's mind in a stolen adult body, throwing tantrums while commanding armies, a walking reminder that Galactor doesn't just kill people, it erases them. You're watching the team realize that winning once doesn't mean anything when the enemy comes back with a new face wearing an old grudge.
Peace doesn't last long for the Science Ninja Team. Two years after Galactor's defeat, Leader X announces his return by sinking the cruise ship Queen Margaret and kidnapping a young survivor, Sammie Pandora, whom he force-grows into the adult villainess Gel Sadra. She is a bizarre figure who still throws childish tantrums. As Galactor rebuilds and starts capturing military and scientific experts, the ISO calls the Science Ninja Team back into action, now with new weapons and vehicles. With Condor Joe missing and presumed dead, the team struggles, and Dr. Nambu brings in a shady newcomer, Hawk Getz, to fill the G-2 slot.
