1. The Horrible Grey
Rhino King Is Hell's Messenger
Two men working on a damn enter the office to find everyone inside dead. Before they can call the police a monster, Gray Rhino King, bursts into the room, and kills one of them. The other is asked where the control center is. When he refuses to answer, Grey Rhino King threatens to break his arm. Suddenly a guitar melody is heard. A young man standing on the damn announces he has come to stop the plans of the Dark Destruction Corps. The man, whos name turns out to be Jiro, jumps off the damn. Gray Rhino King lefts his head to hit Jiro with his horn. Jiro goes flying back into the air. While this is going on the Rhino's prisoner has escaped.
Chasing after their prisoner the Gray Rhino King and his android assistants are confronted again by Jiro. Gray Rhino King charges. There is an explosion. Jiro is assumed to have been killed. However, as the smoke clears, the guitar is heard again. Standing there is a blue and red robot, with a minature speaker in its head, out of which comes the guitar music. The robot indentifies itself as Kikaida. There is a brief battle between Kikaida and the androids and Gray Rhino King. Then Kikaida drives off on a motorcycle with sidecar, the Sidemachine.
Gray Rhino King runs after Kikaida. When he catches up to where Kikaida should be, no one is there, but Gray Rhino King recognises that this is the location of the Dark secret base. Entering the hidden base, Gray Rhino King tells his master, Professor Gill, that their is an intruder, who is some kind of android.
Professor Gill informs Dr. Komyoji, a robotics expert he has forced to work for him, that there is an android intruder in the base. Dr. Komyoji says he would like to see this android. Dr. Komyoji then takes his daughter, Mistuko, into a secret hidden labortery where he has hidden Jiro. Jiro it turns out is a jinzo ningen (artificial human) the doctor had made to defeat the Dark Destruction Corps. Jiro is eager to fight. The doctor and his daughter think they are save in this hidden lab because the doctor has disabled Professor Gill's monitoring devices, however, when the doctor returns to his regular lab the professor is there waiting for him. Androids decend into the secret lab to get Jiro. Jiro fights them. One android is thrown into the electrical system causing a fire. In the confusion Dr. Komyoji orders Jiro to escape, in order to defeat the Dark. Reluctantly Jiro leaves the DCC base, taking the doctor's daughter with him.
As Jiro is driving his motorcycle, a strange sound is heard. It is professor Gill's flute, which drives Dark Destruction Corps robots mad, because Jiro's conscience circuit is incomplete the flute effects him. Though he has to strugle against the effects of the flute, Jiro is stil able to drive his motorcyle through the barricade placed in his way.
Professor Gill orders the destruction of Jiro and introduces the audience to the Dark Destruction Corps (we see only their shadows): Gray Rhino King, Green Mantis, Orange Ant, Blue Buffalo, Yellow Jaguar, Black Horse, Golden Bat, Carmine Spider, Scorpion White, Red Snake, Scarlet Dog, Silver Cat and Pink Tiger. (These monster appear in the series in this order except that Blue Bulldog appears after Black Horse instead of Golden Bat [Golden Bat shows up in episode 15], then Red Condor instead of Scorpion White and Scorpion Brown instead of Red Snake. Scarlet Dog is replaced by Gold Wolf, who is followed by Silver Cat and then Pink Tiger.)
Meanwhile, Gray Rhino King disguised as Dr. Komyoji abducts the doctor's youngest child, his second son, Masaru. Masaru is used as bait to attract Jiro. Gray Rhino King lets Jiro know where Masaru is. When Jiro finds Masaru tied to a bridge and begins to untie him, the bridge explodes. Jiro and Masaru are thrown into the air. Jiro transforms into Kikaida, and catching Masaru, uses the rockets in his feet to fly to safety. Once Masaru is save, Kikaida battles Gray Rhino King.
Kikaida uses his three trademark comabt techniques on Gray Rhino King, "Double Chop", "Giant Swing Throw" and the final blow "Electromagnetic End." Although the Japanese for Electromagnetic End is Denji Endo, in this episode Kikaida can be clearly heard to say "The End". Starting with the next episode however, he says "Denji Endo". When Kikaida crosses his arms and shouts "The End", Gray Rhino King explodes, the pieces that are left over hit the ground.
Mitsuko and Masaru look for Jiro. As they watch Jiro rides away on his motorcycle.
"Kikaida, the mechanical man, was created to destroy the evil of the Dark Destruction Corps. The days of battle begin today... Fight Kikaida... Fight Jiro..."
To be continued.
