Breath of the Wild
Malice can be found in several locations throughout Hyrule Kingdom. Malice can damage Link upon contact. Some pools of Malice have a glowing eyeball which, when destroyed, cause a large chunk of Malice to dissipate. Inside the Divine Beasts and Hyrule Castle, Malice may also have a mouth that is able to release Cursed Bokoblins, Cursed Moblins, and Cursed Lizalfos. These Enemies will continue to spawn and attack Link until its corresponding glowing eyeball is destroyed, should there be one.
At the top of Mount Lanayru, Link can find Naydra covered in Malice. In order to free the Dragon, he must destroy all the glowing eyeballs around its body. During the final battle with Dark Beast Ganon, the remaining Malice surrounds Ganon and converts him into his original form.

Hyrule Warriors: Age of Calamity
Malice first appears as a substance in the Scenario, "Freeing Korok Forest," where it blocks the path to Korok Forest. In this Scenario, the Malice had to be destroyed by defeating the Hollows of each of the Champions, but in most cases, the glowing eyeball needs to be defeated with a weapon in order to destroy the Malice swamp. Unlike in Breath of the Wild, Malice is not poisonous - it only serves as a thing to block the character's path.

- "Glowing eyeballs are a recurring feature in dungeons and wherever large pockets of Malice goo appear, such as in Hyrule Castle." (Breath of the Wild Complete Official Guide (Piggyback) pg. 310)
- "After Ganon was defeated by Link, the remaining Malice pulled itself together to form this bestial creature. [...] This form is considered to be Ganon's original, although in this state, his awareness has been consumed entirely by Malice, and all he knows is a desire to rampage and destroy." — Hyrule Compendium (Breath of the Wild)
