Native to "the fourth moon of the second planet of a dying star," this massive beast is able to spew fireballs out of its eight mouths. Its teeth and very blood are also superheated, giving the impression this is a creature made of fire rather than flesh.
Esplin 9466 Primary morphs into this alien twice (the only "monster" morph he repeats), once as Visser Three and later when he is promoted to Visser One. Each time he does so he utterly overwhelms the Animorphs and devastates the area around him.
