He has to take the possibility of being hunted very seriously, especially now that he has become a dragon which makes him a rare commodity that everyone, including divine beings, would kill for.
So in order to avoid trouble, he activated the new Divine Metac of the Forging Pathway. This new Divine Metac is the Nanite Divine Metac.
The Nanite Metac was created when his Life Ability fused with the Telekinesis Core Metac and his body. It is essentially his body behaving like the Shifting Armor Ability. This effect is achieved with nanotechnology.
So when the Nanite Metac was activated, his body was able to transform according to his wishes. The nanites that make up his body shifted according to will and reshaped his body into whatever he wanted.
