MICROMAN

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.

HUMAN BLANKET

The human blanket is a vegetal symbiotic lifeform that shares the nurrishment it gets from its photosynthesis with its host by wrapping itself around its shoulders.

The blankets were invented by a science-fiction writers in the late 1950ies in one of his novels. In the 2500ies, some Earth publisher was selling the novel, among others, to an obscure species of biogeneticists who found the idea compelling and decided to bioengineer the creature.

HELLHOUNDS OF THE COSMOS

Aggressive sentient reptilian species which developed an expansive advanced interstellar civilisation. They are a bit taller than humans, described as looking like an hybrid of an alligator and a grizzly and can move on two or four legs. They have discovered ways to travel in the void between universes and are so warlike that they would be willing to sacrifice the universe if it allows at least of them to go bakc to the universe's next singularity to mold the next universe in a way that pleases them.
