Capítulo 681: Power-2!!, Athan's subconscious thoughts.

As Athan turned to his Zontheos Prime void frame, his entire internal structure rapidly transformed in a second. His cells transformed to become more condensed and powerful as the potent power of two Abyssal Blood Crystals fueled his body to reach new levels of power.

A dark, blood-red aura covered Athan while his hairs grew long as they reached his knees. His body was buffed a bit as his muscles expanded. A single red horn also grew out from the left side of his forehead as it pulsed with power and glowed red.

This transformation was due to the overwhelming power of Abyssal Blood Crystal properly utilized by Athan's new body structure so that he could bring out his full power.

The giant whale-like creature with six pairs of wings cried loudly in fear as it felt pressure onto itself like never before.

However, Athan finished his transformation in a second, and quite simply, Athan made a fist with his right hand and punched forward.
