Grayroad

Is an elite warrior of the Demon Clan, serving directly under the Demon King as a member of the Ten Commandments.

Appearance
Gray Lord is a large miasma-like creature covered in gray mask-like faces.

3,000 years ago
Along with the rest of the Demon Clan, Gray Lord was sealed away by the Goddess Clan after losing the Ancient War against the Four Races (Human, Fairy, Giant and Goddess Clans).

Albion arc
After Hendrickson managed to remove the seal, Gray Lord and the rest of his fellow Demon Clan members appeared before the terrified former Great Holy Knight and Fraudrin in Dreyfus' body with Zeldris uttered Meliodas' name as if he knew him. After being informed by Fraudrin of the current events in Britannia, Zeldris suggested that they should head for Edinburgh Castle for recuperation of their severely drained magical powers due to the seal they're trapped in, which everyone agreed and left Zhuhur Valley by flight, leaving a terrified Hendrickson.

Arriving at Edinburgh Castle, Gray Road and the Ten Commandments find it in ruins and concludes that it was Meliodas who caused the destruction of the castle as if there was a great battle fought there.

Abilities/Equipment
Like all members of the Demon Clan, Gray Lord possess their unique power of darkness, similar to Meliodas' at Vaizel. He is capable of utilizing this dark power to passively fly on his own. As a member of the Ten Commandments, he may be deemed exceptionally powerful. His aura, along with the other Ten Commandments, was immense enough to have a normally-calm Hendrickson terrified.

He is capable of shape-shifting.
