Grim Guardianess

The Grim Guardianess is a Heartless boss that is found in Kingdom Hearts III. It is the final boss of the Kingdom of Corona.

Kingdom Hearts III
When Mother Gothel succumbs to darkness as she dies, Marluxia transforms her remains into a Heartless for Sora, Donald Duck, and Goofy to destroy, determining that her lingering presence would threaten the real Organization XIII's plans for Rapunzel. The trio fight and vanquish the Heartless outside Rapunzel's tower.

Design
The Grim Guardianess is a tree-like Heartless. Its face is brown and wooden, with yellow eyes and a jagged mouth, while its bottom resembles a stump with scales and green markings. The Heartless insignia is present on its forehead. It is surrounded by a "mane" of green leaves, and four arms emerge from the hair, each also green and tipped with black fingers with purple fingertips.

The Grim Guardianess's name reflects Mother Gothel's grim personality and status as Rapunzel's "caretaker," while its Japanese name, "Mad Mother," refers to her anger and status as Rapunzel's surrogate mother.
