Zahhak「ザハク, Zahakku」 is a major character within Nanatsu no Taizai: Errant. He is the first Demon/Dragon hybrid known, created by both clans in an attempt to halt their then-endless war. Ultimately, his power and rashness would lead to his undoing, as he attempted to destroy both clans. Defeated by their combined might, Zahhak was sealed within the ruined land of Camlann.
However, the man who would become known as the Mad God「狂った神, Kuruttakami」 still had a mark to leave on the world. Fathering children before his death, his descendants would thrive in the land where he rested, growing into the Dahaka Clan.
