The Underlord (boss of the Nether)

Often roaming the Nether, the Underlord is like a golem sized zombie pigman wearing huge netherite armor. He has the lifeforce of an iron golem, and wields a netherite sword. There is only one per world,  making him the boss of the Nether! Wherever he travels his minions, (which include 10 mobs native to the Nether), stay within 15 blocks of him. Once every full moon he will use ancient powers to travel to the Overworld, 100 blocks away from you. He will return to the Nether as soon as the sun comes up. If he dies, he drops his sword, a lot of EP, and his armor turns into enough Netherite ingots to make a full set of armor.
