The Nether Warrior is an unused skin in Minecraft Dungeons supposed obtainable with the Flames of the Nether DLC, but was cut for unknown reasons. It could have possibly been an earlier design for the Strider Warrior skin, based on the name itself and the similarity of the two skins' legs.
The Nether Warrior has clothes similar to an Armored Piglin. It has boots seemingly made of warped stems, and upper pants seemingly made of crimson wood. The Warrior has dark grey hair and blue eyes.
