According to one account, Icthar told Sauvix of Elite Group One that he was the "sole survivor of the Silurian Triad", with Scibus and Tarpok being Icthar's "companions". (TV: Warriors of the Deep) According to another account, Icthar told the Third Doctor that he was the leader of the Triad, with Scibus as Icthar's Second, and Tarpok his Science Adviser. (PROSE: The Scales of Injustice)
When Icthar had awoken in a world dominated by humans, he had made contact with a shelter beneath the island of L'Ithe. Following the death of the shelter leader Daurrix, Icthar made Chukk, whom had already been a favourite of Icthar's, this shelter's leader. The Third Doctor pleaded with the Triad to seek peace with the human race, but this failed after a C19 operative killed Chukk. (PROSE: The Scales of Injustice)
Later, in 2084, Icthar decided, with Scibus and Tarpok, to take over Sea Base 4 with Sea Devil troops and a Myrka, and trigger a nuclear war between two human factions. The Fifth Doctor believed him to be killed, but he had not. After recovering from hexachromite gas poisoning, Icthar shot and killed Commander Vorshak with a Sea Devil weapon. Turlough then forced the weapon from Icthar, and killed him with it. (TV: Warriors of the Deep)
Behind the scenes Edit
- Some fans [who?] [source needed] commonly associate Icthar with the "Silurian Scientist" seen in the TV story Doctor Who and the Silurians. The Warriors of the Deep novelisation suggests a Doctor Who and the Silurians appearance of Icthar, although Icthar is simply described in the Warriors novelisation as a Silurian other than "Old Silurian" and "Young Silurian" who said little, which does not appear to synch up with the characterisation or dialogue of "Silurian Scientist". The novelisation also changes Icthar's line from the TV story about his Silurians offering a hand of friendship to the humans which led to a treacherous attack to one where the Doctor says he tried to offer peace between the two races, but failed because of the destructive efforts of extremists on both the human and Silurian sides.
- The Target novelisation of Doctor Who and the Silurians, Doctor Who and the Cave-Monsters, does not name the scientist, Old Silurian or Young Silurian as "Icthar", but respectively as K'to, Okdel and Morka.
- Additionally, Icthar appears in the novel The Scales of Injustice, which also establishes that Silurians belong to different races or sub-species, with Icthar belonging to a different sub-species than the one seen in Doctor Who and the Silurians. Just as in Doctor Who and the Cave-Monsters, the novel also identifies K'to as the "Silurian Scientist".
