Lotapareen were not humanoid in form. They had three legs arranged in a tripod, with a slim upright body and three arms. Their heads were ovoid and they had saucer-like eyes and stumpy snouts. They also had lizard-like skin, ranging in colour from grey to turquoise to yellow. Their third arm protruded from their chests; each arm ended in a hand with three fingers. The Tenth Doctor and Donna Noble met Mesanth, a member of the Cult of Shining Darkness, during their visit to the Andromeda Galaxy. (PROSE: Shining Darkness)
