Chief Defense Oka Falls into the Sky!!. Jangal sent a robot that can transform itself to become a ring that can control the mind of whoever wears it to Big Falcon. Megumi found and wore the ring and soon the ring took over her mind and ordered her to kill her own father, General Oka. At the last moment, General Oka could snap Megumi out of the ring's power and sent her away to safety, right before the beast fighter hit his helicopter and blew it into pieces.
