Te Fiti

Te Fiti is a goddess with the power to create life and a major character in Disney's 2016 animated feature film Moana. After her heart had been stolen by the demigod Maui, she became Te Kā, a demon manifested of fire and magma that served as the main antagonist of the film. A damaged and emotionless shell of her former self, Te Kā looks to slowly plunge the world into darkness and eradicate humanity as punishment for Maui's insolence.

Appearance
Te Fiti, as well as her Te Kā aspect, is an enormous embodiment of the earth, but her appearance differs between the two forms.

The colossal Te Fiti takes the form of a feminine figure with a human face not unlike Moana's. Her body is covered in lush flora and trees; clusters of flowers adorn her grassy hair similar to a headdress. She can also assume an island form when dormant; when this happens, she assumes a resting position.

Massive in size, Te Kā towers above all who encounter her, and is usually depicted with a hollow scowl. She is comprised completely out of lava, with molten skin and flames as her hair. Always surrounding her slender form is a dense pyrocumulus cloud, coupled with bolts of lightning and volcanic ash. On her chest is a spiral carving of where her heart once was; should it be reattached, Te Kā will return to her true form.

Personality
Te Fiti's sole purpose is to spread life across the ocean. She values nature and the beauty that comes alongside it. Moving with gentle grace, often seen with a tranquil expression to match her radiant features, Te Fiti is selflessness and purity incarnate. Though she will not hide her displeasure in those who wrong her, she is forgiving should the individual in question look to redeem themselves.

Te Kā is - quite literally - a heartless creature with a fiery deposition. The theft of her heart has stripped her of Te Fiti's benevolence, replacing it with malice aimed at both Maui and the world at large. Te Kā and Te Fiti are polar opposites, with differing goals and ideals; while Te Fiti wishes to spread life and beauty, Te Kā seeks to bring death and corruption, purely out of the belief that mankind is undeserving of the gifts that were previously brought to them by Te Fiti. As it was Maui who was responsible for the theft of Te Fiti's heart (and not mankind as a whole, thus making them innocent), Te Kā can be painted as a vindictive and arguably purely evil entity.

Despite this, Te Fiti's purity lies deep within Te Kā. Should someone call to it, as Moana did during the climax, she will slowly ease her tension and succumb to her inner, gentle nature.

Powers and Abilities
Te Fiti's power lies in her ability to generate life around her and her control over it as a goddess of life. A living island, she can grow plants of all sizes and can manipulate the terrain around her body. With her heart, she can create other islands teeming with flora and fauna, and affect these elements from afar, as shown by Te Kā's curse. However, she could also rejuvenate the life in islands Te Kā's curse had once affected. Because of her godly status, she was also able to create and recreate items previously destroyed, such as Moana's boat and Maui's fish hook (which itself was a weapon forged by the gods).

As Te Kā, most of her abilities are derived from her elemental control over fire, lava, and magma. With these assets, she can create fireballs and turn matter into molten rock. Aside from water, which can temporarily turn her lava form into molten rock, Te Kā does not appear to have any true weaknesses. The only way to truly "defeat" her is to subdue her long enough to return Te Fiti's heart to its rightful place. This will inevitably obliterate the being known as Te Kā, and revive her true identity.

She is also extremely power in her strength—so much so that she overpowers the capacity of a demigod, though one can pose as a decent adversary for a period of time.
