When Seiya was pushed beyond the breaking point by Thanatos, his cosmo approached the level of the Gods. His Cloth (which had shattered into dust) reacted to both his cosmo and Athena's blood, evolving into something closer to the gods' Kamui. It was immensely altered, going beyond even the Gold Cloths in power and appearance. Attacks from the lesser god Thanatos left the God Cloth virtually unharmed. Even with this great strength, Hades' attacks proved more effective, even to the mighty God Cloths. The Pegasus God Cloth was beyond any of it's predecessors in appearance, covering almost all of the body in a golden, ornate armor. Every piece of the Cloth contains detailed patterns which stick off of the Cloth like the metal was cut around it. The leggings cover even further up the thighs with flexible regions for movement. The belt and chest have merged into one body piece that covers the entire upperbody, and even provides much needed groin shielding. The gloves now match one another in design, and go all the way up his arms, providing more full protection. The helmet portion is bigger and now covers more of the face and head. The Cloth was last seen as Hades stabbed through it, piercing Seiya's heart, showing it's still not quite enough to face a powerful god.
The battle with Thanatos destroyed both the Bronze Cloths of Seiya and his fellow Bronze Saints, plus five of the Gold Cloths. In a moment of desperation born from Thanatos' threat on Seika's life, Seiya's emotions fueled his cosmo to the level of a god. This godly cosmo awakened Athena's blood in the shattered remnants of the Pegasus Bronze Cloth, turning it into the Pegasus God Cloth. This version of the Cloth has a level of strength beyond any other level of Cloth seen up to this point. This design is above and beyond it's anime predecessors, with most of the body being covered by detailed, ornate metal. There are obvious traces of the prior design, like the helmet looking similar, but the detail is what makes most of the difference. Unlike in the manga, the Pegasus God Cloth isn't golden, but similar in color to the prior Cloth versions. This version of the Cloth was last seen as Hades took out Seiya, proving the power of a god in his true body.
To say this was the shortest lived variation of the Pegasus Cloth would be an understatement. Saint Seiya: Tenkai-Hen Overture showed us what their version of a God Cloth would look like for about...2 seconds before moving on. Given that they hadn't reached that point in the Hades OVA, it's somewhat understandable, but still, this design is never seen again after this point. In terms of design, it does seem much closer in detail to the manga version, with many of the details kept, and even seems to have some of the depth that the original version had, but one major distinction is the color choice; while the manga went for a pure gold, Tenkai-Hen went more for a pure silver.
