Protoplasm

Protoplasm was part of a cell. According to the Fifth Doctor, it was "the basic form of human life" from billions of years before Tegan Jovanka's time, from which humans evolved. (AUDIO: Interstitial) The natural forms of the Iyteans, a symbiont race, were little more than "three pounds of protoplasm". (GAME: )

The Saiph were able to turn into protoplasm. (AUDIO: The Stealers from Saiph)
