Minecraft wiki entry for Piglin_Brute, associated text: Piglin brutes were created late in 1.16's development, so they were pushed to a minor release as the developers did not want to add a new feature so close to release.[3]
The golden arm guard is meant to work as a "protection" and is the reason behind their high health.[4]
Piglin brutes have no pupils, unlike Overworld pigs.
Sounds that are used by the piglins are lower-pitched when used by the piglin brute (like the converted_to_zombifiedsound).
Piglin brutes were made to trigger normal piglins when attacked, as to encourage players to avoid or maneuver around them.[5]
