Isis is Gary Seven's cat and partner
Isis in human form
Isis was the pet cat owned by Gary Seven.
In 1968 she was involved in the sabotage and detonation of a nuclear bomb in the atmosphere, thus making governments re-consider deploying orbital nuclear weapons.
Isis is more than she initially appeared to be. Exactly what she was still remains a mystery. Evidently, she was capable of understanding Gary Seven, and of communicating with him in at least a rudimentary almost telepathic fashion, and she accompanied him wherever he went. Isis was also able to take Human form. The one thing that never changed was the collar around her neck. (TOS: "Assignment: Earth")
- Isis in human form was played by Victoria Vetri in an uncredited role.
