DAEMON
Elder God of Evil and Chaos, Defiler of the light, Sworn Enemy of Innoruk and Ni' Pregh
DAEMON is the ultimate of all Evil.  All evils in the universe, be they of Senshi or Nitro Origin.  Daemon has only one goal, the complete and utter annihilation of all creation, and to this end, has enslaved Nitro Galaxia to collect Starseeds.  Before the creation of Nitro and Sailor Astrum, DAEMON was sealed into a sword, a black blade so black that you can't look at it for long without burning your eyes, which matched his skin.  DAEMON has forever loathed Innoruk and Ni' Pregh for sealing him in the sword, but since Galaxia found the sword, he has inhabited Nitro Galaxia, as he used the powerful weapon.  Nitro Galaxia, no longer exists as a person.  All that is left of him is the empty shell that DAEMON inhabits.  When DAEMON has collected enough Starseeds, he will escape, and bring about the end of the universe.  Another condition of his escape was, if he never collected enough Starseeds to escape, that the light of an innocent would free him.
