Hadji Singh is one of the main characters of Hanna Barbera's Johnny Quest series as well as The Real Adventures of Johnny Quest. Is a streetwise 11-year-old Calcutta orphan who becomes the adopted son of Dr. Benton Quest and also Jonny's best friend. Rarely depicted without his bejeweled turban and Nehru jacket, he is proficient in judo, which he learned from an American Marine. The seventh son of a seventh son, Hadji seems to possess mystical powers (including snake charming, levitation, magic, and hypnotism) which may or may not be attributed to parlor trickery. The Quests meet Hadji while Dr. Quest is lecturing at Calcutta University; he saves Dr. Quest's life (by blocking a thrown knife intended for the doctor with a basket lid) and is subsequently adopted into the Quest family. Though slightly more circumspect than Jonny, he can reliably be talked into participating in most any adventure by his adoptive brother. He is voiced by Danny Bravo.
