Zorc Necrophades

Zorc Necrophades (called Zorc the Dark Being) is a "Great Evil God" who was created out of the darkness of people's hearts, and his dark power is what is later used to create the Millennium Items and their powers. He was slain by Cavendish Ōtsutsuki.

Appearance
Zorc appears as a large, purple-skinned demon with huge, curved horns, bat-like wings, and a large dragon/snake appendage between his legs. He is very similar in appearance to Diabound (albeit much larger and more demonic), which is possibly due to his connection to Thief King Bakura and due to the hatred against Cavendish Ōtsutsuki for interfering his attempt to destroy Dens.

Abilities
Zorc, having been born from the darkness of people's hearts, has power exceeding that of the Millennium Items, which were created using his powers. Because his powers stem from darkness itself, there is virtually no limit to his powers, which he stated multiple times.

A testament to his powers have been how Zorc had singlehandedly defeated Exodia the Forbidden One, the three Egyptian Gods, and the Blue Eyes White Dragon. He had also fared equally against the Blue Eyes Ultimate Dragon, and didn't withstand the attacks of Cavendish Ōtsutsuki.

3,000 years ago, at the end of the Grand Civil War, Zorc was slain when Cavendish Ōtsutsuki used a spell to destroy his heart, and brain and soul and Raimei Ōtsutsuki, through the power of creation, using the powers to vaporize him completely.

When he was revived in the Memory World, he was finally destroyed when Atem remembered his name and then combined the 3 Egyptian Gods to summon the Creator of Light. The Creator of Light was Zorc's only weakness.

Aside from its immense durability and power, Zorc is able to make attacks made of darkness, capable of cutting powerful beings in half, petrify enemies, create a solar eclipse, and shooting fire created from his hands or fired from the dragon/snake appendage. Also, when his heart and brain was destroyed, Zorc loses it's dark powers completely and die in blood loss.
