good parts eh?...hmm well...Kamen Rider is originally a story created by Shotaro Shinomori, a mangaka from Japan, about a young man named Hongo Takeshi who was abducted by evil organization SHOCKER and have been modified into super-humanoid-locustform-cyborg called 'Hopper'.He almost brainwashed completely before he could escape the horrible SHOCKER who chased him brutally.
In a deep dilemma of being a half-monster,Hongo decide to use his 'new' form to fight back evils wherever it is.
Well that's the basic story of the very first Kamen Rider heheheh...
