While much of the initial "Micronaut" toyline offerings were simply repackaged versions of Takara "Microman" equivalents, some items in the "Micronaut" toyline were original Mego creations that used modified and reconfigured parts from existing Takara toys. For example, the larger, magnetic action figures Baron Karza and Force Commander were re-colorings of the Magnemo "Kotetsu Jeeg" action figures with newly designed heads. In addition, as the "Micronaut" line grew in popularity, Mego expanded the line by creating whole new figures from scratch such as the "Aliens" line which included Antron, Repto, Membros, Lobros, Kronos and Centaurus.
