A 1977 mecha show where four psychic teenagers have to pilot a giant robot to save a kidnapped professor's family, and the real tension comes from the fact that none of them asked for this. The show doesn't waste time pretending the kids are heroes, they're just the only ones with powers strong enough to matter. By episode three, you realize the alien threat is less interesting than watching four teenagers who barely know each other learn to synchronize their minds inside a machine built to destroy things.
Aliens land on a quiet forest lake and abduct Professor Katou, a leading space engineer, along with his family. His second son Yuuji, an American football player who ran away from home, is in the middle of a game and has no idea anything has happened. Four young psychics, Mark, Dickey, Franco and Yuri, who have been training at a secret base, saw the previous night's events and believe Earth is under attack. They use their powers to snatch Yuuji, because the transforming robot Baratack can only move when all five combine their strength as one. With the cry of "Pentagoras Unite!" the robot appears, and a furious Yuuji throws himself into the fight against the Golteus reptile army. The show is a science fiction mecha adventure about five young people with special powers defending the planet from an alien invasion.
