From left to right: Icthar, Scibus and Tarpok.

Icthar is the leader of the Silurians in the Doctor Who episode "Warriors of the Deep".

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.
