Venusian aikido

The Third Doctor defends himself. (TV: Inferno)

Venusian aikido (sometimes called Venusian karate) was an unarmed combat style used by the Doctor in multiple incarnations, including their third, fourth, fifth, sixth, eighth, twelfth, and thirteenth, as well as several of their companions including Sarah Jane Smith, Jo Jones, and River Song, to defend themselves and others.

According to some accounts, and the Thirteenth Doctor, it was developed by Venusian nuns (TV: The Ghost Monument) on Venus, which meant it worked best with five arms and five legs (PROSE: First Frontier), with the Doctor musing that he was one of the few two-armed beings to become truly adept with the martial art; (PROSE: The Eight Doctors) when asked by Nardole how he managed Venusian aikido, as, to Nardole's knowledge, one "needed five arms for Venusian", the Doctor quipped that he had "hidden talents — as well as hidden arms". (TV: World Enough and Time) Another account stated that the Doctor himself had invented it. (PROSE: Interference - Book One)

It could be used to immobilise an opponent by using pressure points (TV: The Mind of Evil, Inferno) and perform joint locks, throws and kicks. (TV: The Claws of Axos) It tended to use the attacker's own movements against them. (PROSE: Freedom) These were effective against many different humanoid species, but were useless against non-human duplicates and seemed to have no effect on Ogrons or Sontarans. (TV: The Claws of Axos, Day of the Daleks, The Time Warrior) While amnesiac and trying to remember his Venusian aikido training, the Eighth Doctor recalled "flying through the air" before turning back to face his Venusian instructor. (PROSE: The Eight Doctors)

Behind the scenes

• Barry Letts was opposed to the idea of an aggressive Doctor. Therefore, Terrance Dicks suggested aikido as it has no attacking moves. (DOC: Can You Hear the Earth Scream?)
• In the comic story Terrorformer, which is set after Robot of Sherwood, the Twelfth Doctor states that he has just remembered knowing Venusian karate, suggesting that Venusian karate and Venusian aikido may be different disciplines.
