The red core is extremely unstable, dangerous and corruptive counterpart of Blue Core. Unlike the Blue Core, the Red Core is unstable and destructive. It also allows whichever powered by it to regenerate and assimilate for its own. This was proved when President Stone inserted it into the Peacekeeper twice, though the second time was worst. Red Core, along with it's blue counterpart, are created from the fragment of a star that located million years away from planet Earth that no longer exist in the present. It’s not mentioned how the cores’ material acquired, either gained through expedition to the outer space or the material itself fell on Earth as a meteor before the scientist examined it and discovered it’s nature as star fragment. Either way, the energy that gained from the star fragment has properly harnessed and encased within spherical cores. During the extraction process, it’s revealed that the energy within the star fragment consists of bluish white positive energy and the reddish jet-black negative energy. Both energies are cancelling each other due to it’s opposing properties: blue energy is more stable and safe than it’s red counterpart that was unstable and dangerous. This was discovered when the positive energy extracted completely from the star fragment, left the fragment nothing but highly unstable and corruptive red energy. So, they decided to have them inserted into separate cores that must be separated at all costs. Unlike it's counterpart that could potentially restore earth's environment, the Red Core is unstable and able to either destroy/corrupt anything. It's safe to assume that Red Core energy's potential is ultimate destruction, as it can destroy anything in cellular level. This was confirmed when the Peacekeeper's energy blast completely nuked Toby.
