Natron

Natron was an ancient evil entity which dwelt on Planet X and was imprisoned there in a comatose state by a being known only as the Protector. He was reawakened by an archaeological expedition, and revitalized himself by draining the lifeforce of Warp Darkmatter. Leaving to conquer Capitol Planet, Natron was battled by Warp and Team Lightyear, who finally restored Warp's life energies and returned Natron to his sleeping state. Natron was also known as Natron the Destroyer and many other dark names.
