A trio of young Headmaster warriors were sent to rescue the two. Eventually, Toraizer found them deep in Scorponok's Megazarak transtector. During their escape, Tatsuya pilfered a component of Megazarak that prevented the giant scorpion from moving. This allowed the Headmasters to use their Master Typhoon attack to destroy the transtector and send Scorponok fleeing. The Young Headmaster Warrior Trio Arrive!
