The "Eight-Headed Dragon" is an unknown species, presumably extinct. It stands on eight legs, has eight spindly arms with three claws at the end of each arm, and from the place where its top set of arms grow, eight heads extend. It is capable of projecting a ball of fire from seemingly any of its eight heads. Visser Three informs the Animorphs that he acquired the DNA of this creature "on the fourth moon of the second planet of a dying star".
