Blavasse

The Blavasse is a creature native to an unnamed swamp planet or Thanos' World.

Biology
Blavasses are white grub worms whose mhru (feces) is consumed and used as a major food source by the Gloks.

A unique trait of this animal is the ability to undergo several transformations.

At the first stage it starts out as a big fat white worm, the Blavasse will create a cocoon around itself to become its second stage, swamp turtles called a Blatouille. After that it will go onto its third stage and evolve into the semi-intelligent Blattru.

A fourth stage exists but only one in a million Blattru are capable of it, where the grow large and become a Blattor, a massive spider-like creature capable of surviving in the vacuum of space. There is a fifth stage of evolution, though it is only rumored and few have ever truly documented it. However in a rare instance, it was noted that a Blattor will shed it exterior shell, and emerge as a giant crystalline mantis with a body made of pure carbon with mercury in its veins. Through the transformation process, this state allows the creature to feed on cosmic rays for its final form. Once enough heat is acquire, the form will shatter and produce the final "ultimate" transformation.

In reality the final transformation, merely a return to the first state, a Blavasse, creating a cyclical form of immortality.
