BOOM!!
World-ending thunder cracked across the sky. Above the sea, the spirits, cells, and fundamental life structures of the four Primordial Ancestors began to rapidly merge into a single mass.
GURGLE GURGLE!
At this moment, it was completely impossible to distinguish their original forms. They had become a single, writhing mass of flesh and blood.
As they fused, their unique, signature abilities also began to rapidly combine.
Sai's abilities over flesh and germs served as the foundation, rapidly reshaping their body and forming a special layer of defensive armor on the exterior.
Isaac's abilities formed the core, with the energy sources from all Nine Great Furnaces integrating into the new flesh.
