Tetsujin Tiger Seven

Tetsujin Tiger Seven (鉄人タイガーセブン, Tetsujin Taigā Sebun), translated as Iron Man Tiger Seven, was a Japanese tokusatsu television series that broadcast on Fuji TV from October 6, 1973 to March 30, 1974 with a total of 26 episodes, produced by P Productions and Distributed by Metro-Goldwyn-Mayer Television. Unlike Kaiketsu Lion-Maru and Fuun Lion-Maru which focuses on cat-based ninja heroes, this series is set in modern Japan.

Takigawa Go gets the power to transform into Tetsujin Tiger Seven from an artificial heart and a magic pendant. To transform, he utters the henshin (transformation) phrase "Tiger Spark". Takigawa Go is played by Tatsuya Nanjô who also starred in Henshin Ninja Arashi. Go rides a Suzuki motorcycle with rocket boosters. When he transforms into Tiger Seven, the motorcycle transforms as well to become "Spike Go". Spike Go can drive itself, coming to its master's aid when Tiger Seven roars.

Tetsujin Tiger Seven was apparently P Productions' attempt at a Kamen Rider style series. They even hired Shunsuke Kikuchi, music composer of the first eight Kamen Rider television series, to write the music for this series.
