Nekronís full powers are unknown; it is possible that they have no limit. He is immortal and has displayed the ability to raise the dead, reanimate the dead as zombies, kill with a touch, fire bolts of black lightning, communicate telepathically, alter reality and grow without limit.
Scythe: Nekron has made use of a long black scythe as a signature weapon which contained a Black Power Battery at its top and a curved blade powerful enough to rip holes in reality and harm cosmic beings such as the Life Entity itself.
Nekron was an ancient cosmic being who was formed when the Emotional Spectrum was initially shattered and harnessed by sentient beings such as the Guardians of the Universe who claimed the embodiment of the emerald light of willpower. Before this time, there was said to had been peace in the darkness of death but the shattering of The White Light and rise of life led to an imbalance in the universe. Thus, it sought to create its own "Guardian" which manifested in the form of Nekron who sought to return all of existence to its original state.
Eventually, Nekron became to be the ruler of a dimension that adjoined Hell and also seemed to border between Limbo and Purgatory. This Realm of the Dead was the location where souls of the deceased awaited passage for their final resting place as well as residence in either the Silver City or in Hell. Due to his nature, the Lord of the Unliving drew his power from the souls and the spirits of all those who had died which were subservient to his will. Despite his mastery over the dead, this Realm of the Dead served as a form of imprisonment for Nekron who sought to free himself from the shackles that tied him to that dimension as he sought to claim more souls.
