Mother Nature

Emily Jane, also known as Mother Nature, is a powerful, but mysterious, being, as well the daughter of the Nightmare King, Pitch. She is described as being "a force nearly as ancient as Pitch".

Appearance
Mother Nature is "a tall, cloaked woman" who "holds herself with a regal air", with a "long, yet lovely" face. Her black hair is very long, and both her hair and clothing appear to be one with the clouds that surround her form.

Personality
Despite Mother Nature's apparent neutrality, Bunnymund remarked that she is quite unpredictable and not always kind. She has her own agenda, being neither good nor evil, as indicated by the way her winds thwarted both Pitch's forces and saved North from a mortal wound prior to abducting Pitch and Katherine for her own purposes.

When Mother Nature was child, she frequently disobeys her mother, who wanted her to stay at home, her father, on the other hand, loved his daughter's wild heart and turned a blind eye to her sailing around her home.

Powers and Abilities
As her name suggests, Mother Nature has control over the elements of nature. She can manipulate natural phenomena such as the winds and clouds, and cause hail and lightning. Her presence also imbues leaves, clouds, winds, rain, snow, thunder and lightning.

She is also able to keep herself hidden while she watches people, but some, such as Toothiana and Nightlight, can feel her presence.

Role in the Crossover
Much like her role in the books, Mother Nature is relegated to the side as a secondary character. Unlike other characters in the fandom, Emily Jane is normally omitted from the continuity unless the story itself calls for it (i.e. Seasons Guardians). Much like in the books, she maintains a neutral position.

Mother Nature can be considered an official character in the fandom from her role in FOUR: the audio drama.
