First Apperance: Majestic #11


History:
The Planet Shapers were developed by the original Kheribum to spread their seed across the cosmos. Planet Shapers are designed to land on primal planets and to use the local gene pool to create a variation of the original Kheribum.

The Planet Shaper that landed on Earth failed to activate because it's bank of Kheribum genes was damaged upon planetfall. Years later, Kheribum from the planet Khera would try to use Earth's Planet Shaper to their own ends.
