While a Super Robot series at heart, it depicts a realistic take on the genre, such as announcing to nearby citizens that Trider G7 was being activated and having to consider the monetary expenses of battle.

Invincible Robo Trider G7 portrays the attempted alien invasion by the Robot Empire to take over Earth.

Rebelling against this, the scientist Nabalon, who was exiled from the Empire, meets the protagonist Watta's father, and together, they design the transforming robot Trider G7.

Up until that point, many series airing on TV Asahi in the series' timeslot had their soundtracks composed by Takeo Watanabe and Yuushi Matsuyama, but as the two were working on the soundtrack for the theatrical adaptation of Mobile Suit Gundam, Kurando Kaya filled in the role.

In addition, the Robot Empire was notable compared to other villains from contemporary mecha series by having little to no interaction with the human protagonists, as they are unaware that their own scientists built Trider G7.
