When Micro-Earth was destroyed, the Micromen M10X fled in hibernation capsules. The alpha H-7 radiation emitted during the explosion transformed the capsules in crystal structures. They drifted through space for four billion years. The rays of the sun revived the micromen who had landed on Earth. They found out that the alpha H-7 radiation, reacting with the environment of the crystallized capsules, had reduced their body to a smaller size and altered their appearances. They built the M115 Conning Tower to send out Spectrum MX Ray that would revive the other Micromen from their hibernation.
