Riderman
Kamen Rider V3 episodes 43 through 51
Riderman: Originally a scholar loyal to the evil Destron, is in unison with Kamen Rider V-3.
-- from an article in the Star-Bulletin & Advertiser, 1970 something.
When High Destron lets it be known that he is considering promoting scientist Yuki, Joji (Yamaguchi, Akira) to a leadership role in Destron, Marshall Armor fears losing his positiion so he frames Yuki, Joji for treason against Destron. Though innocent Yuki, Joji is sentenced to be executed by immersion in acid.
His fellow scientist attempt to rescue him, arriving to in time to save his life, but only after his right arm had been disolved by the acid. The other scientists lose their lives saving his. Before their deaths Yuki, Joji's friends perform surgery on him replacing his lost arm with a cybernetic arm. Yoki, Joji is not a true cyborg, he doesn't have a henshin belt instead he stores the Riderman costume in his motorcycle. Although he doesn't have a henshin belt he does have a henshin sequence. Riderman is 175 cm (5 ft 8 inches) tall, weighs 70 kg (154 lbs) and can jump up to 10 meters (33 feet).
Riderman has several artifical arms, all with different functions. The two he uses most often are "Rope Arm" which has a hook used for climbing, swinging or grapping hold of an enemy, and "Power Arm" which is used as weapon in combat or to break down doors.
Not used as much are "Net Arm", for capturing his enemies and "Swing Arm", a flail on a rope instead of a chain.
In one episode he uses his "Drill Arm" to drill an air hole in an air tight room. "Drill Arm" requires an external power source to function (in other words it has to be plugged in). I don't remember seeing Riderman use "Sickle Arm", but it looks leathul.
Riderman is not a full cyborg and is therefore not as powerful as the other Riders. What Riderman lacks in strength he makes up for in persistance, he never gives up.
At first Riderman is not an enemy of Destron, just Marshal Armor and will go from fighting the forces of Marshal Armor to fighting V3. This is because Yuki, Joji was raised by the leader of Destron. Eventually Riderman comes to recognize that Destron is evil and joins Kamen Rider V3 in fighting it.
Riderman's motorcycle, Rider Machine, was a non-transforming motorcycle. Rider Machine's top speed was 250km/h (approx. 155 mph), making it the slowest of the Kamen Rider motorycles.
Just as there were the evil Shocker Riders in Kamen Rider there was an evil Destron Riderman that tried to ruin the reputation of the real Riderman (episode 47).
At the end of episode 51 Riderman appears to be killed in a nuclear blast. Kamen Rider V3 declares him to be "Kamen Raidâ Yongo" (Kamen Rider #4), for sacrificing his life to save Tokyo. However, one year later Riderman would appear alive and well in the short movie "Kamen Rider X: Five Riders Vs King Dark", without explaining his survival.
Riderman had his own theme song, "Our Riderman".
Yamaguchi, Akira would also star in Denjin Zabohga as Daimon Yutaka, the man who controled the robot.
Yamaguchi, Akira died of liver cancer Apirl 6, 1986. He was only 39 years old.
