The Eye of Thaloc was a weapon wielded by Setrákus Ra. It was created through unknown means and resided in a gold scepter, acting as symbol of power to the Mogadorians. The Eye was destroyed by Number Nine in The Revenge of Seven, during their exposure of MogPro and battle with Ra at the United Nations.
The Eye of Thaloc resided in a scepter described as a golden cane, "its head curved like a hammer." The Eye itself appeared to be painted on, but bursted into ash when destroyed by Nine, implying it was augmented into the object.
The Eye of Thaloc was capable of altering the appearance of its user, as well as either numbing or causing pain when aimed at someone. In The Power of Six, the Eye is described as turning red and becoming capable of ripping people to shreds.
