Mazinger Z is a gigantic Super Robot, constructed with a fictitious metal called Chogokin Z (literally Super-Alloy Z), which is forged from a new element mined from a reservoir found only in the sediment of Japan's Mt.Fuji. The mecha was built by Professor Juzo Kabuto as a secret weapon against the forces of evil, represented in the series by the Mechanical Beasts (mecha used for evil purposes) of Dr. Hell-wiki
The Mazinger Z papercraft has seven pages of un-colored parts and stands at 17 cm high when built.
