Mazinga is arguably the guy that started the super robot craze in the United States. Back in the late 1970's Mattel decided to import toys made by Popy (of Japan). Mazinga, also known as Great Mazinger in Japanese, became the iconic figure of the Shogun Warriors line.
This version of Mazinga is the first version with green styrafoam and extra stickers along with more leg articulation. Later versions deleted some features as a cost savings.
Both firsts fire and the toy comes with a collector paper along with red swords.
Great Mazinger (グレートマジンガー Gurēto Majingā) is a manga comic book and anime television series by manga artist Go Nagai, made as a direct continuation of the successful Mazinger Z series. It was aired on Japanese television in 1974, immediately following the end of the first Mazinger series, and ran for 56 episodes.
