Tarak Ital is a character from the 2009 Doctor Who special "The Waters of Mars". He is portrayed by Chook Sibtain.
Born in Karachi in 2026, Ital was originally interested in athletics, and went on to represent Pakistan in the 2044 Olympics in Havana, Cuba. Despite winning a gold medal, he quit athletics and went into medicine instead, first studying locally and then at Harvard University, though many Pakistanis believed he was turning his back on the country. He began focusing on space medicine. While at the Johnson Space Centre, he befriended Yuri Kerenski and recommended him as base nurse for Bowie Base One.
In 2059, he was surprised when the Tenth Doctor came to the base as there was no way of getting there. He later assisted the Doctor and Adelaide Brooke in heading to the base's bio-dome after there was some unknown attack. He searched on his own for crew member Andy Stone, only to be infected with the Flood. He joined Andy in spreading the infection into the base's control hub.
Tarak and the other infected colonists were killed when Adelaide activated the nuclear self-destruct system in the heart of the base. Like the other casualties of the mission, he would be remembered as a hero on Earth for years to come.
