Who is the Kikaida in Lee Tonouchi`s short prose piece?

Unless you were raised in a cave on Kaho`olawe, you probably know about Kikaida, but in case you donʻt, the fansite Generation Kikaida describes the storyline as a "classic good-versus-evil tale, the show pitted a guitar-playing, denim-clad young biker named Jiro, played by actor Ban Daisuke, against the evil DARK, a shadowy criminal organization bent on wreaking havoc upon Japan. Professor Gill (Ando Mitsuo), the mastermind behind all the evil plots, has kidnapped brilliant robotics scientist Dr. Komyoji (Izu Hajime) and forced him to build a battalion of android monsters to serve Gill's malicious ends. The only one who can save Japan from Gill's evil designs is Jiro, himself a Komyoji creation. Jiro, actually the human form of an android, can transform into the mechanized superhero Kikaida."

And here is the opening of the show featuring that classic song. Sing along if you know the words. You know you want to.
