Metal Heroes with Super Sentai
- This is a list of Metal Heroes series along with the Super Sentai series it aired alongside.
In the 1990s, Saban adapted some of the Metal Hero Series shows for American audiences in the United States, just as he adapted Super Sentai into Power Rangers. Stock footage from Metalder, Spielvan and Shaider was used in VR Troopers (1994–1996). Later, footage from both B-Fighter series was used in Big Bad Beetleborgs and Beetleborgs Metallix. Both shows ran for two seasons and ended when all the stock footage from those series were used up. Some costumes from these shows would later be used in Power Rangers most notably when costumes for the Beetleborgs were used as the Machine Empire Generals in Forever Red.
In addition, Marvel Comics published 5 issues of VR Troopers in a flipbook with the Ninja Rangers. Acclaim published a oneshot comic featuring a Team Up between the Turbo Rangers and the Beetleborgs Metallix.
