Malice

Malice is a poisonous substance that was unleashed by Calamity Ganon in.

Characteristics
Malice can be found inside several Dungeons and Towers throughout Hyrule and even covers one of the three Dragons, Naydra. Malice is a physical manifestation of Calamity Ganon's evil power. It looks like a purple and black sludge that covers walls, floors and even some creatures. It damages Link upon contact. Sometimes pools of Malice have a large, orange eyeball somewhere. The only way for Link to destroy Malice is to destroy its eyeball - for example using an arrow - causing a large chunk of it to dissipate away. Inside of Dungeons, Malice may also have a mouth that is able to release Malice infected heads resembling Bubbles known as Cursed Bokoblins, Cursed Moblins and Cursed Lizalfos. They will continue to spawn when defeated and attack Link until a corresponding Malice eyeball is destroyed.

During the final boss battle with the Dark Beast Ganon, the Malice around Hyrule will all surround Ganon and possess him into his 'true' form. .
