The shuttle base was hijacked by the space beastman Dodon, and the Changemen were attacked by Dodon and thrown into the sea! Sayaka, who is left alone, discovers that Dodon is vulnerable to certain radio waves. I contacted the swords to find the source of the radio wave and decided to fight alone in the shuttle base. On the other hand, the sword found that the Satoru boy's radio was the source. Dodon is suffering when the radio waves are strengthened. Now, the counterattack is about to begin! Changeman! Get the shuttle base back!
