Moon (KingofEvil9)

"Why do you fight back? It's not like your people respect your work." - Moon speaking to Luna

Information
Moon is a Shadow Spirit created by Dalzo himself in order to act as a potential commander to his first Shadow Army. Her goal was to find a powerful and suitable host to possess in order for her to become physical and help her master conquer the Multiverse. However, while she was searching for her host, Dalzo stopped waiting and began his attack, leading to his death and the banishment of his remaining troops. This lead to Moon wandering around the Multiverse still looking for a host in order to finish her master's plan of conquest. She then ended up asexually multiplying as she journeyed, eventually creating the Nightmare Forces, who would serve as her personal army down the road. Eventually, she found Luna and proceeded to follow her home. Entering her dreams while she slept, Moon managed to use Luna's jealousy of Celestia in order for her to give in to Moon's influence and give her control over her mind and body. This lead to Luna lashing out at Celestia and causing her to transform into Nightmare Moon, Moon's new physical body. However, both Moon and Luna were beaten and banished to the Moon as punishment for their crime. 1000 years later, Nightmare Moon returned to Equestria and began another attempt at fulfilling Luna's hope of showing Equestria the night's beauty and Moon's hope of destroying the Multiverse. Again, she was beaten and Moon ended up becoming suppressed inside Luna's mind, trapped in slumber. Delanis eventually learns of her existence and kidnaps Luna and begins to force her to awaken Moon and become Nightmare Moon again for his own needs.
