Zandra was a witch that Lotor went to for a new weapon to use against Voltron. She'd just finished a potion that could turn any normal plant into a horrific monster. When King Zarkon supposedly became deathly ill, Lotor ventured to Arus in search of the berries that could save his father. Zandra gave her potion to him before he left. After gathering the berries and being beaten by Voltron again, Lotor threatened Zandra to drink Cobra blood. She suggested that he give the drink to his father instead.
