Hydra (ヒドラ Hidora) is a supernatural Kaiju that was apparently awakened by the soul of a child who was killed by a careless driver. It attacked several motorists before being countered by SSSP and eventually Ultraman. The Kaiju was allowed to escape, however. Its whereabouts are unknown.
Subtitle: Plateau Dragon (高原竜 Kōgen Ryū)
Years ago, a young boy named Akira was killed on Route 87. Afterward, the SSSP was visited by a young boy declaring that the mythical dragon Hydra would be arriving soon. Just as the Science Patrol investigated strange lights around the tip of a mountain, they discovered that the boy whom was killed had created the Hydra as for a park. Soon the Hydra breaks out of the mountain, roaring the world and vowing to get revenge on the motorists that had killed Akira. The beast leads a path of destruction, attacking vehicles on the road.
The Science Patrol manage to fight back, deploying powerful laser weapons against the creature. A blast to its chest manages to rip it open, but this only enraged the winged monster. As it approached, Hayata transformed into Ultraman. The two forces clashed, but Hydra managed to dodge Ultraman’s Spacium Beam. As Ultraman’s energy began to run low, the monster began to fly away. Watching on, Ultraman allowed it to escape as the spirit of Akira appeared on its back. The monster was never seen again.
