Sunstone

The Sunstone is an Eternian artifact that is housed in the Temple of the Sun. As its name implies, it generates power by absorbing energy from the sun.

Negator once tried to absorb the energy of the Sunstone to become more powerful than He-Man, but his plan backfired when Prankster blocked out the sun with rainclouds and caused the Sunstone to absorb Negator's energy instead.
