Some say the Nether Golems were created by the once powerful wizards.

Nether Golems are sentient creatures created from lava and netherrack. They eat mushrooms the grow from netherrack.

Appearance:
🔥 Nether Golem are made out netherrack and sometimes netherrack with quartz.
🔥 Their mouth and eyes are made of fire and lava.
🔥 Other than the mouth and eyes, the lava drips from wounds that don't ever heal.

Clothing:
🌋 The chest plate is made of gold mixed with glowstone dust. The gold comes from mining. It is then melted and forged by piglins who only ask for protection (and sometimes gold) in return.
🌋 The shorts, shoulder protectors and armbands are made from dyed hoglin hide. The hoglin hide is dyed using crushed nether bricks. The Nether Golems wear shorts because they once saw a "wizard" wear something like that. They tried wearing pants but they were too impractical.
🌋 Shoes aren't need in the Nether Wastes. Nether Golems can walk in lava and fire without sustaining much damage.

Environment/Habitat:
🔥 Literally just fire, lava and netherrack.
🔥 There are occasionally nether fortresses and abandoned portals in their area.

Behavior:
🌋 Nether Golems are friendly most of the time.
🌋 If a piglin that they have a bargain with is attacked by a "wizard" then they defend the piglin.

Sustenance:
🔥 They eat mushrooms the grow from netherrack. They also eat Hoglin meat.
🔥 They drink lava.

Legends and Myths:
🌋 A story that is passed from golem to golem is that there is a place where the sky is blue and there is green and brown looking netherrack.
🌋 They have also found books left by the "wizards". The books tell of a great and powerful dragon which the "wizards" have defeated.

Death and Decay:
🔥 As the Nether Golems obtain more and more injuries, they become more and more lava until the melt back in to the very ground they came.
🔥 Even without battling hoglins and such, they still get daily wear and tear from moving and just existing.

Heres a little drawing I did:


I had a friend who helped me with proportions. Lol, otherwise it would be a blob with eyes.


The design process:
🟪 So I kinda started it knowing I had to do a a nonhuman. As doing a human wouldn't stand out.
🟪 I proceed to mark off biomes that I shouldn't do by looking at entries and watching what most people decided to do for their biome. I noticed that Nether Wastes wasn't done as much. I really wanted to do the savannah or jungle but their just wasn't enough to work with in those cases.
🟪 So I thought why not make a golem like character. Golems are typically creatures made out of clay and water. So why not netherrack and lava.

The original design looked like this:

I later realized it looked too humanoid.
