Lich

The Lich is a Pureblood Heartless that appears in Kingdom Hearts III. Unlike other Heartless, it does not consume hearts to create more Heartless. Rather, it captures hearts and ferries them to the abyss of darkness. Also uniquely, if caught in time, it can be forced to relinquish the hearts it has captured, allowing them to return to their bodies.

Kingdom Hearts III
The Lich first appears at Olympus to collect Riku's heart after the guardians of light have been consumed by a Demon Tide and scattered across the worlds. After Sora chases the Lich down and frees Riku's heart, the Lich flees into a portal leading to other worlds to claim the hearts of the other fallen warriors—Aqua in The Caribbean, Goofy in Arendelle, Donald Duck in Monstropolis, Ventus in Toy Box, Mickey Mouse in the Kingdom of Corona, and Lea in San Fransokyo—forcing Sora to use the power of waking to give pursuit. Upon finally vanquishing the Lich, Sora is told by Young Xehanort that he has misused the power of waking too many times, and is condemned to meet the same fate as those whose hearts are taken by the Lich.

Design
The Lich is a large black Heartless with the shape of a roughly humanoid torso. It wears a black robe which fades into white tendrils at its base, and has draping sleeves that end in pink points. Its tall, pointed headdress covers its head and long neck with a criss-crossing design ending in a flair at the shoulders that resembles white hair or feathers. Its glowing yellow eyes peer through a skull-shaped mask. A heart-shaped hole cuts through its chest, in which is stores the chained hearts it captures, bordered by a bright pink design on its robe. Three chains dangle from under its robe, ending in pink spikes that hang at alternate heights.

It bears a grey staff with a black headpiece, which also features a heart-shaped hole through it.

Its name is derived from the recurring enemy from the Final Fantasy series.
