School teacher Andrea Thomas was on a archaeological excavation in Egypt when she uncovered a box containing the Amulet of Hatshepsut. The mystic artifact showed her images of the past, in the Ancient Egypt, when Hatshupset gained the amulet from its creator and used its power for the good. Instinctively, Andrea placed it around her neck and was granted the power of the Egyptian goddess of fertility Isis. As Isis, Andrea begun a super-hero career to serve mankind. Andrea has a Minah bird named Tut, which often helps her in dangerous moments.
- Amulet of Hatshepsut: The Amulet of Hatshepsut is the source of Isis' power. Without it, she is a normal human being.
- Divine Empowerment: When Andrea Thomas wears her mystic amulet and speaks the words, "Oh Mighty Isis," the spirit of the Goddess enters her body. Andrea's personality is submerged until Isis uses her powers over time and space to change back into Andrea. The power of the Goddess Isis grants Andrea several superhuman abilities.
- Transformation: Andrea Thomas can instantly transform into the costume and Isis by speaking the magic words "Oh Mighty Isis". To transform back to Andrea Thomas in her clothing, she speaks a spell: "Ancient gods of time and space, put Andrea Thomas in my place."
- Chlorokinesis: One of the many applications of Isis' command over the elements is the ability to manipulate and control plant life.
- Animal Empathy: The Amulet of Hatshepsut provides Isis with a natural affinity for wildlife. As the amulet's creator first said to Hatshepsut, "You will soar as the falcon soars... run with the speed of gazelles, and command the elements of sky and Earth".
- Flight: Another application of her control over the elements is the ability to summon a strong wind to give her directional flight. This is usually accomplished by speaking the words "Oh zephyr winds which blow on high, lift me now, so I can fly!", though Isis has also demonstrated the ability to fly without a spoken mantra.
- Telekinesis: The amulet also grants Isis the ability to move objects with the power of her mind.
- Clairvoyance: By using a second amulet affixed to her brow, Isis can perceive objects from a remote distance. She can only use this ability to see things taking place in the present. The exact range of this ability is unknown.
