Hikolossa is a Spectrobe that resembles a dinosaur. Besides the main head with a double jaw, it has 4 more heads (making 6 pairs of eyes) and numerous spikes covering his body. Two rotors emerge from its back and spin rapidly when it is awake, keeping it airborne. The flame patterns that adorn its body are taken from Hikodrake's design, and the core at its chest in its previous evolution is now shielded by jaw bone in between 4 of the 6 heads.
Hikolossa has 13 spikes from its head to the tip of its tail, two longer ones on the minor shoulder heads, four on the arms and two more on the knees. If the claws on four other limbs are counted, Hikolossa has a total of 35 sharp appendages. However, none of them are used in combat as it is a ranged attacker.
Only four of its six heads are animated; those on the shoulders have no hinges and thus cannot open their mouths freely.
