For fans unaware, Mazinger Z was created by legendary Manga Artist and storyteller, Go Nagai, he created the characters back in 1972, with an anime version debuting in the December of that year. The show was then succeeded by Great Mazinger in 1974, and then later by UFO Robot Grendizer. Mazinger has enjoyed massive popularity, in Japan and worldwide. Mazinger was also shown briefly under the name Tranzor Z in 1985. Recently Mazinger returned for an all new movie called Mazinger Infinity, which had a limited stateside theatre release.
For those interested, here is the original opening to the anime adaption of Mazinger Z and of its 2009 remake
What do you think about this crossover? What other Super Robot series do you think would work well with Transformers? Let us know in the Energon Pub and stay tuned to Seibertron for all the latest news and reviews!
. Yes ever since seeing Tranzor Z myself as a kid (along with of course Transformers, Voltron Robotech etc...) I have been just as big a fan of Super Robots as I am of Transformers. This is a crossover I never thought would happen, can't wait to get this amazing comic. 
I didn't include it though as I just wanted to focus on Mazinger Z 
. Also I recall, it may just have been an April Fools day thing (like with Hello Kitty a few years back), but I thought I saw a mock-up of Movieverse Prime in a SRW game once.... 
also I think it was just an April's Fool's joke about movie prime being in the game but there's always a chance, I mean think of the scenarios, like Starscream getting confused by seeing the macross valkyries
