Original title: ゴーゴー仮面ライダー

The Shocker Organization sends two of its Inhumanoids to destroy an atomic plant, but their plan is foiled by an invisible barrier that surrounds the complex. Because of this, they abduct a top soccer player and convert him into Tokageron, a lizard Inhumanoid capable of kicking a 5 kg bomb to destroy the plant's barrier. Kamen Rider must once again combat the Shocker and prevent them from destroying the atomic plant.
