Bellal

Bellal was an Exxilon.

Biography
Residing with his people, the Subterranean Exxilons, deep below the planet's surface, Bellal watched as food become scarcer and his people died around him. He hoped to destroy the Great City and read the symbols outside its entrance many times with the aim of deciphering them, without success.

In the tunnels, Bellal observed Sarah Jane Smith and joined her and the Third Doctor, telling them about his kind. He led the Doctor to the city and entered it with him, the Doctor solving each of the tests and Bellal temporarily being controlled by the city to shoot him. They reached the control room and, after the brain of the city was destroyed, they fled and watched the destruction they caused, as well as the explosion of the Daleks' ship. (TV: Death to the Daleks)

Appearance
Bellal was small, grey and hairless and had small ears and big eyes. His face was a dull, "faintly luminous" white and he wore a tattered greenish cloak which appeared at first to be his skin and served as camouflage. He moved like a lizard. (PROSE: Death to the Daleks)
