Yu-Gi-Oh! ZEXAL - Episode 013
Dr. Faker (Dr.フェイカー Dokuta Feikā?) is the father of Kite and Hart Tenjo and the main antagonist of the World Duel Carnival arc, he is a seemingly evil man who desires the destruction of the Astral World via the forceful collection of all 100 "Number" cards. His evil persona is later revealed as nothing more than a farce, due in part to the revelation of a deal with a being called "Barian" regarding the well-being of Hart. As such, he took extreme interest in Hart's power, and is therefore overprotective of him. Faker was responsible for the mutation of Vetrix and the disappearance of Kazuma Tsukumo.
