|First Appearance||The Gauntlet|
Polymorphs are a species from the molten planet of Viscosia.
Polymorph's are unicellular organisms that are generally green in color, however they do come in different colors.  They are gelatinous humanoids with a pointed head and and an asymmetrical, drippy ameoba-like shape. When in humanoid form, they have four fingers on their hands.
According to Matt Wayne, he imagines Polymorphs to be scavengers, dissolving and processing any unclaimed organic matter. 
Powers and Abilities
Polymorphs can revert to a puddle, a shapeless mass or mimic the shape of something.
Physically harming Polymorph is extremely difficult as solid objects and even energy passes through them without any damage.
Polymorphs have strong digestive acids, which can be used as an offensive weapon, either by smothering something or releasing a sort of corrosive gas.
The Anti-Gravity Projector is not native to the Polymorph's; they are for Polymorphs that travel to planets with stronger gravity then Viscosia. The slime is normally in a humanoid shape with a pointed head, narrow eyes and spikes on their shoulders.
On planets with stronger gravity then Viscosia, Polymorphs are tied to their Anti-Gravity Projectors and lose control of their forms if they are separated from their projectors.
