Jumborg Ace (ジャンボーグA(エース) Janbōgu Ēsu) is a fictional mecha created by Tsuburaya Productions, and the titular fighting robot of the 1973 Tokusatsu television series. Jumborg Ace is actually an airplane that can transform into a fighting robot, which is piloted by Naoki Tachibana.

The year after his series, Jumborg Ace appeared in a Japanese/Thai coproduction, Jumborg Ace & Giant.


Jumborg Ace

Young air delivery boy Naoki Tachibana is out to deliver a package for his grumpy boss Daisaku Banno, when his older brother Shin'ya (Toshiaki Amada), who commanded the defense force, PAT (Protective Attacking Team), was killed in an attack by a giant monster called King Jyglus (which was sent by the evil alien Anti Go-Ne of the Planet Groth). 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 Cessna into the monster, to their shock. When the monster downs the plane, Naoki and his plane are teleported into an energy world by an Ultraman-like alien from the Emerald Star.

The Alien Emerald has instantly used his technology to completely modify Plane JA3395, as well as Naoki's wristwatch. He suddenly finds himself back in his cessna's cockpit in the real world, but he hears the Alien Emeralds' 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 VR movement-control suit, piloting the robot from inside the head with his own physical movements. He fights with King Jyglas, eventually destroying the monster. But his battle against the Alien Groths has only just begun.
