Additionally, thanks to Izuna's modifications to his magic during the Baptisma 17 incident, he has also tapped into the ability to use the Soul Sinker system, a powerful and almost obscure summoning ritual that allows him to manifest his soul(also known as a Master Ghost) into physical reality and create Servants, powerful familiars born from his soul. Though, due to his relative inexperience with this magic and risks involved in manifesting his Masterghost (which would result in the obliteration of his soul should it be destroyed), he does not use it often. He has made use of the matter displacement aspect of this spell to create materials that he can use to construct his weapons and even a new vehicle, the Fire-Wheel MK II, which he needed after his Servant.

Whenever Sol becomes serious or desperate, he may rely on his own latent Gear powers to give him an extraordinary boost. Whenever he first does so, his body flashes a silhouette, as if to contain an inner beast. In truth, this is him holding back his transformation. When he was a bit younger as a Holy Knight, the silhouette has wings and a long tail, which suggests that in his current state, he has been able to repress it almost entirely. However, due to the encroachment of his Dragon Install caused by the Flame of Corruption, he will transform into a dragon-like creature with his blade wrapped in infernal flames shaped into a sword when properly provoked, allowing him to go toe-to-toe with That Man.

However, it had been stated that even in this form during the fight, Sol had not actually went all out, nor did he remove the Gear-Cell limiter on his head, which may suggest an even more drastic transformation should he release all of his power. He has since learned to repress his Dragon Install into more humanoid forms as seen in Vastedge and Xrd.

With his manipulation over darkness, Zato-1 can create anything from his shadow, from constructs such as swords to monstrous beasts. He is also able to feflect bullets and magic with his shadows. He can meld with darkness itself to completely alter his body's composition and density, either becoming a liquid-like substance or pure mist. Due to the ability of his "Dark Space", which is a subspace of darkness, this also allows him to teleport whether he chooses and easily control anything that casts a shadow.

After his return from the Underworld, it is stated that he has become even more powerful.
