Polymorph (Ben 10)

Polymorph (a word meaning "many shapes") is a species of unicellular organisms from the molten planet of Viscosia.

Apperance
Polymorphs are gelatinous, 200 lb, extraterrestrial blobs that come in many colors, including light green and red. The Polymorph's slime body is controlled by an anti-gravity projector (a small, grey UFO-like machine) hovering over their head. This is the Polymorph's real head, as well as where their voice comes from. It allows Polymorphs to hover off the ground and change shape.

The slime is normally in a humanoid shape with a pointed head, narrow eyes, and "spikes" on their shoulders. They can, however, revert to a puddle, a shapeless mass, or mimic the shape of something.

Abilities
Polymorphs have strong digestive acids, which can be used as an offensive weapon, either by smothering something or releasing a sort of corrosive gas. Polymorphs are almost invulnerable because even when their slime has been scattered all over the area, they can still recollect as long as their anti-gravity projector is still active.

Weaknesses
Outside of Viscosia gravity, Polymorphs can only have it's body function when it is united with its anti-gravity projector, meaning if the two are separated by the shortest distance, the slime will go inert until recollected.
