As the Overworld has two Golems, it makes sense for each main dimension to have the same. These two golems are the Marble Golem(TBC) and The Cloud Golem.
The Marble Golem (Tier 1)
Not fully developed yet, this golem's exclusive power is yet to be decided. As a Tier 1 golem, it is less powerful than the Cloud Golem.
The Cloud Golem (Tier 2)
This floating, powerful Golem shoots clouds at enemies. Like Iron Golems, it is sometimes found in Villages. Once a village's Cloud Golem dies, it is ressurected by a SkyMage. These golems prioritise Endermobs, but any mob they kill will not drop anything.
