Red Core (Earth-101001)

The Red Core is extremely unstable, dangerous and corruptive counterpart of Blue Core. Unlike Blue Core's energy, the Red Core is an orb of pure dark and negative energy from the very centre of Vestroia that initially trapped Naga within it. Naga slowly evolved until he took control, possessed the Red Core and become Silent Naga. He became undefeatable until The Fusion Tenders used Dextra Attack to ultimately defeat Naga. Code Eve revealed to Marcus and Drago that when the Cores split and Vestroia became the world of the six attributes, the enormously light and dark energy that gave the few humans their powers on Earth.
