Bok

Bok was a stone grotesque which had been animated by Azal's power and used by the Master to gain control of the residents of Devil's End and resist any attack. After the Master was defeated and Azal and his spaceship were destroyed, Bok ceased to be animate and was destroyed by UNIT. (DW: The Dæmons)

SenéNet acquired Bok's remains. (PDA: Business Unusual)

Characteristics
Bok had glowing red eyes and was somewhat short in stature but very powerful. He could vaporize objects and people instantly as well as resist injury, including being blown apart. However, he did have a few significant weaknesses such as being afraid of iron and the tendency to be mollified by Venusian lullabies. (DW: The Dæmons)
