Characters from other franchises have also been featured in some of the initial games, as well as in the Compati Sports series, such as Mazinger, Getter Robo, Devilman and Godzilla.

It was the first video game series to involve a crossover between animated giant robots and live action tokusatsu heroes from different established franchises.

The crossover was also possible due to Banpresto's parent company Bandai holding the merchandising rights for all the properties associated with the series.

The series was successful with children thanks to the SD Gundam craze, but after the release of Charinko Hero for the GameCube, there were no new games afterward for nearly eight years.

Banpresto released a new game in the series titled Lost Heroes for the Nintendo 3DS and the PlayStation Portable in September 2012.
