were sold as "Micro-Kit Machine Series" sets which required assembly prior to use. Project Victory (1975) Following the success of the first 1974 Microman Zone series, Takara completely revamped and expanded the Microman concept to be a stand-alone line on its own and not merely a smaller-scale version of their Henshin Cyborg line. The former original Microman figures were now given sturdier "cybernetic feet" and all figures now contained standard ports which allowed for interchangeability between sets and figures. Takara also introduced a new line of die-cast figures dubbed Super Steel Microman and a new line of "enemy" figures dubbed the Acroyears. Additionally, all figures were now identified by a new alphanumeric figure-type designation system—such as M10X, M11X, M12X, M20X, M21X, M22X, etc.—across the whole line as well being given formal, character names such as George (M101), Jack (M102), Jesse (M103) and John (M104). Spy Magician (1976) In addition to new vehicles and figures such as Spy Magician (M13X & M14X), Takara introduced a new class of figure dubbed the Titans which employed a magnetic ball/joint system that allowed for a new level of interchangeability between toys. Japanese pop-culture character tie-in toys were also released (such as Microman Jeeg, Robotman Gakeen and Robotman Mechadon) which helped expand Takara's line beyond its own in-house characters and opened the door to greater licensing opportunities for their designs. Microman Command (1977) A Microman manga was published in TV Magazine, a children’s oriented magazine published by Kodansha Ltd., in 1977. Takara also introduced the Microman Command line in which each figure came in its own unique capsule case (shaped like Easter Island figures, the Statue of Liberty, etc.) and included the first female figure, Lady Command (M18X), in the line. Police Keeper (1978) With the release of Star Wars in 1977, the market for science fiction merchandise became increasingly filled with competing science fiction related products. New figures such as the Police Keeper (M23X), Micro Knight MC-X and Cosmo Satan Arden (A35X) built on the success of prior Microman action figure releases. Takara’s attempts to expand the Microman line concept with the Micro Hoodman (H70X) and construction/building playset Play Build line of toys with the large-sized Build Base playset were not well received. Lack of a positive response to the new line was strong enough that previously announced toys in the line, such as the remote control Hoodman spaceship Hoodman's RCB Noah, were cancelled.
