Tetsujin Taiga Seven, or Iron Man Tiger Seven, is a tokusatsu series that aired from October 6, 1973 to March 30, 1974 for 26 episodes.
Father and son Professor and Go Takigawa discover the ancient temple of the Mu Empire, but when Go is attacked by a Sand Primitive Sand Grudge, the Professor performs a heart transplant, replacing Go's heart with a artificial one. He also gives his son an ancient pendant. Soon after, the Mu attack again, killing everyone on the research team except Go. He vows to avenge his father and friends. He uses the combined power of his pendant and artificial heart to transform into Iron Man Tiger Seven with the words "Tiger Spark!".
Tiger Seven's Fight Glove is the source of many of his combat techniques, such as the "Tiger Cutter" karate chop and "Tiger Hawk", which can make his glove pierce a monster's body. Using his belt, he can heal wounds, and by releasing "Tiger Energy" into the body of a person whose heart has stopped beating, he can save them. "Buckle Energy Red Zone" can release all of his energy in one blast, and his mouth can release a gust of wind called "Tiger Hurricane". "Tiger Eye Attack" has his eyes firing a yellow beam, and similarly, the jewel in his head, "Tiger Point" can use sunlight to fire the "Tiger Head Beam". His motorcycle's equipped with rocket boosters to increase speed.
Go works with Professor Takaido and his students, and only the Professor figures out that Go is Tiger Seven. Student Shiro Kitagawa ridicules Go for running away whenever a monster appears, as he mistakes Go's fleeing to transform for cowardice.
