Grendizer vs Steel Jeeg

Grendizer Vs. Steel Jeeg is a short manga based on an unproduced crossover movie between UFO Robot Grendizer, Steel Jeeg and Getter Robo G that was slated for a 1976 release by Toei Animation.
== Plot ==
After their two previous defeats, the now weakened Damdom empire lead one final assault on Planet Earth with the few remaining monsters they have and succeed in brainwashing Hiroshi Shiba, transforming the young cyborg into Steel Jeeg, now forced to fight against Grendizer.
With the combined efforts of Grendizer and Getter Robo G team, Hiroshi is freed from his mind control and the new team proceed to work together to eliminate the last of Damdom's monsters. As the Damdom leaders tried fleeing back into space, the 3 pilots of Getter Dragon ultimately destroy their mothership in a single blow to avenge the death of Musashi who had been killed by their monster Grangen. 
With their reign of terror defeated, the 5 heroes celebrate, vowing to preserve their alliance if any other threat tries to destroy humanity.
== Production ==
After the success of Grendizer, Getter Robo G, Great Mazinger: Kessen! Daikaiju, Toei Animation planned on creating a follow up to the Great Mazinger and Getter Robo crossover duology involving the mecha from Grendizer, Getter Robo G and the then newest coproduction between Toei and Go Nagai, Steel Jeeg coming together to defeat the mysterious aliens and avenge the death of Musashi Tomoe, the original third pilot of Getter Robo killed by their monster Grangen. 
Due to conflicts between the rival toy sponsors of Jeeg (Takara) and Grendizer (Bandai), it was never animated. However a short 4 page manga based off of the unmade script was produced in the 70's and drawn in the same style as all three series. As such it gives a glimpse into what could have been.
== Trivia ==
* Due to the movie ultimately not being produced, Steel Jeeg was one of the only Go Nagai/Toei series not featured in Dynamic Heroes. It is possible that some plot points from the story treatment were reused for the manga however.
*Steel Jeeg would have been depicted as smaller than Grendizer and Getter Dragon being one of the only cases where a series' canon size for the mecha was used as reference by the writing and art team, unlike the previous crossover movies' which depicted all the robots as the same size as each other despite established heights existing for them.
