Synopsis
A mysterious spaceship descends upon a tranquil lake within a forest, where its occupants abduct Professor Katou, a leading figure in space engineering, along with his family. His son, Yuuji, an American football player who had estranged himself from home, remains oblivious to the incident as he participates in a match. Observing him are Mark, Dickey, Franco, and Yuri, a quartet of psychics trained in a hidden facility. Having witnessed the abduction, they suspect an extraterrestrial threat and determine that their only recourse is to activate the transforming robot Baratack. To do so, they forcibly recruit Yuuji. The robot operates solely through the unified psychic energies of the five individuals. Upon shouting "Pentagoras Unite!", Baratack materializes, channeling Yuuji’s intense combat fury into a fierce determination to destroy the Golteus reptile army.
