The Evil Spirit

The Evil Spirit also known as The Spirit is the true main antagonist of the entire series as   she was behind every action: Creating Wendigos, Sirens, Nightmare Moon, The Pony of Shadows, Corrupting Discord, Queen Chrysalis, King Sombra, Tirek, Cozy Glow, The Storm King, Stygian, Starlight Glimmer and many more.

She is depicted as a sentient magic-book with the face of the malevolent witch on it, she is extremely manipulative, slanderous, uncaring, cruel, and utterly wicked - utilizing a friendless young boy named Nicholas as a pawn by which to take over the world and get rid of everything that is good and pure and replace it with wickedness and corruption.

Appearance
The Evil Spirit initially appears as a feminine yellow face in the book with green eyes and purple lips and eye shadow, but later turns green when she became more powerful.

The letters on her pages contain Nordic runes as well as Celtic symbols on the corners of her cover which also has a carving of her face.

Personality
The Evil Spirit is very wicked, cunning, arrogant, deceitful, fraudulent, manipulative, calculating, egocentric, deceptive, and ruthless, doing whatever it take to get Nicholas to do what she wants him to.

She falsely promises to help him make friends, but instead makes him feel worse about himself, and convinces him to try and get revenge by ridding the world of all good feelings.

Her motives for wanting to rid the world of good feelings are unknown.

She uses Nicholas only for her own benefit and is almost completely without redeeming characteristics - making her a true villain and one of the more evil characters in the My Little Pony universe, her power was also seen as great - though she was ultimately little more than a book and as such without the aid of Nicholas, she was much less powerful and persuasive.

Powers, Skills and Abilities
The Spirit, though almost useless without Nicholas, proved to be very powerful, mostly with the spells written in her book.

The Spirit could also enter a more powerful green state, throw things away from her with green waves of energy, and fire a powerful beam of light from her lock.

Although she is shown to be able to perform non-verbal spells, she required Nicholas to cast the "final spell" since she could not gather ingredients and had no usable arms.

She seems to be only villain who seems to be immune to the Elements of Harmony, she even used a spell to weaken them to make sure Nicholas would not lose.

She is one of the most powerful foes the Mane 7 have ever faced.

She created the Alicorn Amulet and the Corruption Book.
