Slime-Biot

Slimebiotes resemble a small green glob with tendrils. They have little antennae sticking out of their heads and their eyes are small and straight.

Diet
According to Khyber, Slimebiotes feed on DNA.

History
According to one of the Contemelia, Slimebiotes are the most important beings in all of creation as they will carry, mix, and deposit DNA across a growing universe for eons. Slimebiotes predate the universe and will seed life across new and growing universes.

In the billions of years, Slimebiotes had forgotten the original life mission of their species.

Powers and Abilities
When attached to an alien, Slimebiotes can use the alien's DNA to create extra limbs.

Slimebiotes are impossible to remove by force (except by ionic surgery), since they only leave their hosts if they choose to.

Etymology
Slimebiote is a combination of slime and symbiote.
