Jumborg Ace (1973)

A tokusatsu/science fiction/kaiju/superhero TV series. Produced by Tsuburaya Productions, the show was broadcast on Mainichi Broadcasting System from January 17 to December 29, 1973, with a total of 50 episodes. This was also one of several shows Tsuburaya did to celebrate the company's 10th Anniversary (the other two being Ultraman Taro and Fireman). Young air delivery boy Naoki Tachibana is out to deliver a package for his grumpy boss Daisaku Banno, when his older brother Shin'ya, who commanded the defense force, PAT (Protective Attacking Team), was killed in an attack by a giant monster called King Jaigras (which was sent by the evil alien Anti Go-Ne of the planet Gross). When PAT retaliates against a second attack by the monster, Naoki, in retaliation for his brother's death, suicidally tries to ram his air delivery plane into the monster, to their shock. When the monster downs the plane, Naoki and his plane are teleported into an energy dimension by an Ultraman-like alien from Planet Emerald. The Alien Emerald has instantly used his technology to completely modify the plane, as well as Naoki's wristwatch. He suddenly finds himself back in his cessna's cockpit in the real world, but he hears the Emerald Alien's voice, telling him to activate his wristwatch, and upon shouting the command "Jum-Fight!!!", his jet transforms into the giant cyborg, Jumborg Ace, with Naoki, in a virtual reality movement-control suit, piloting the robot from inside the head with his own physical movements! He fights with King Jaigras, eventually destroying the monster. But his battle against the Gross Aliens has only just begun...
