Icthar

From Tardis Wiki, the free Doctor Who reference

Icthar was one of a Triad of Silurian leaders.

Following his revival into a world dominated by humans, Icthar decided, with his fellows, to take over Sea Base 4 with Sea Devil troops and a Myrka, and trigger a nuclear war between two human factions. His familiarity with the Fifth Doctor suggests an earlier encounter. Turlough shot him with a Sea Devil weapon while he was recovering from hexachromite gas poisoning, he attacked and killed Vorshak as his last act. (TV: Warriors of the Deep)
