Basevolver

Basevolver is the natural predator of Polymorphs, appearing on Viscosia.

Appearance
He is a skeleton frog-like, with a huge dome instead of a stomache. Inside his hollow body is a boiling amount of basic liquids.

Note, his entire body is bone-colored except for his entire chest, from the neck to the shoulder to the underbelt part, which is a transparent glass dome revealing his base liquids.

Basevolver has robotic parts over his skeletal system. He has red eyes, and his basic liquids are red.

Abilities

 * Gravikinesis: Basevolver can easily immobilize a Polymorph and revert it to a puddle by focusing his gravikinesis on its body by staring at it.
 * Tough Layer of Skin: Basevolver's body is surrounded by a layer of skin that is extremely invulnerable to acidic attacks. Additionally, it secretes mucus that prevents goo from trapping the skin.
 * Enhanced Jumping: BAsevolver can jump practically long distances very quickly, so it can keep up with a Polymorph's quick travel.
 * Prehensile Tongue: Basevolver has the ability to extend a long stream of basic liquid from his body as a form of tongue. It uses this tongue as an attack way or to lick in Polymorphs.
 * Basic stomach (inner body): Inside his body is a storage of basic liquids that can react and neutralize a Polymorph's acidic body.

Weaknesses
Bsevolver's outer skin is just as durable as a snail's shell. It can crack with physical attacks and shatter with enough force.

More Natural Information
When he devours a Polymorph, a Polymorph's acid pH reacts with the base pH of a Polymorph Predator's stomache, thus making the Polymorph die. A Polymorph predator has different color of base liquids, and they have different colors, for example a red Polymorph predator eats a red polymorph to sustain himself and disallow his stomache's base liquids from dissolving him.

Trivia

 * The other part of his name "evolver" is a hint to the main protagonist of this series this is referring to, being his natural predator.
