1966's "Magic Serpent" ("Kairyu Daikessen" or Decisive Battle of the Giant Magic Dragon) emerged from Toei Studios rather than Toho, perhaps best known for Sonny Chiba's "Terror Beneath the Sea" or Robert Horton's "The Green Slime," as well as TV feature "Voyage Into Space" (derived from JOHNNY SOKKO AND HIS FLYING ROBOT). Preceding Daiei's Majin trilogy by mere months, this joyous combination of ancient Japanese folklore with giant monsters opens with the betrayal and murder of Lord Ogata by once trusted general Yuki Daijo (Bin Amatsu), aided by ninja sorcerer Oroki Maru (Ryutaro Otomo), who then assumes the form of a sea serpent to pursue Ogata's son and rightful heir to the throne (the serpent is dubbed with Godzilla's roar combined with green Gargantua Gaira). All the men perish as their craft is crushed by the dragon, only for a giant eagle to carry the boy to safety (this winged savior is dubbed with the sound of Mothra). Ten years pass and the lad has grown into the handsome Ikazuki Maru (Hiroki Matsukata), like Oroki taught to master the mystic arts by the same teacher, elderly Dojin Hiki (Nobuo Kaneko), who has decided that the time has come for Ikazuki to learn the truth about his heritage and to avenge the honor of his parents. An ambush by Oroki's ninja servants results in what appears to be a beheading, Ikazuki's laughing head seating itself on a nearby log while his headless body frightens the would be assassin to take his own life (the head reattaches itself backwards, then makes the right adjustment). Pretty young Sunate (Tomoko Ogawa) witnesses the carnage, wrongfully assumes that the survivor was the aggressor, and finally realizes her mistake as he agrees to help find her long missing father, following her mother's recent death. Oroki manages to trick his old master into a fatal snake bite, though the dying man is still able to send the couple on their way to see usurper Yuki Daijo. Sunate learns the identity of her father yet cannot bring herself to obey his orders when it comes to taking a life, setting up a climactic battle between Oroki's water spouting dragon against Ikazuki's fire breathing horned toad (dubbed with the sound of Rodan), with a brief appearance from Sunate's summoning of a giant spider that spins its web all over the serpent. For once, the addition of four monsters weren't necessary to the plot, action packed and fast paced from start to finish, though obviously dubbed at a later date for AIP-TV since "The War of the Gargantuas" had yet to be made by Toho. The titular serpent closely resembles Manda from Toho's "Atragon" and later "Destroy All Monsters," only with larger claws that can be used more effectively in smashing its opponent. One can easily imagine filmmakers like George Lucas or Quentin Tarantino taking note of this unjustly forgotten opus for future reference, certainly good enough for US theatrical release.
