Deetra was Tonus' lover. She studied humans and was starting "to make some waves in the scientific community." She believed that humans could be integrated into ape society, but was sadly mistaken as a human killed her with a spear. Tonus is still haunted by her memories and is often found at Gracela Tavern drinking away his sorrows.
- Deetra is exclusive to the continuity of the Planet of the Apes comic books published by Malibu Graphics.
