Sinbad is the former King of Sindria, the World Innovator, the Head of the International Alliance, as well as the president of the world's most powerful trading company, the Sindria Trading Company. He is a Dungeon Capturer and a King Vessel. He was also the leader of the Seven Seas Alliance. Sinbad has halfway "fallen into depravity", as noted by Ithnan. Though it was originally thought that Sinbad was the reincarnation David Jehoahaz Abraham, Sinbad has stated that he is not. However, David did resonate with the black Rukh inside of Sinbad after the summit ended. Sinbad is often accompanied by members of the Eight Generals, who are his most trusted companions. He is a major character in Magi and main character of Adventure of Sinbad.
He is a member of the Council of Light in the Purple sector and was recruited during the Sindria Arc and found it interesting.
And he is reprised by Matthew Mercer in the English dub and Daisuke Ono in the Japanese dub.
