Hey Guys! This is For The Boss Battle Skin Contest. I also came up with a backstory! Hope you guys like this!:

    Steve wasn't always alone, he once had two friends called Nathan and Endre.








    When Steve was back at the overworld, the first thing that came out of Endre's mouth was "Where's Nathan? Is he dead? What happened to him?!" But Steve ignored the questions and asked, "Do you want to want to continue exploring or not?" Endre nodded and followed Steve. They came across a cave and went inside hoping to find diamonds. They spent a week in the cave and found five diamonds, two for a sword and three for a pick. And during that week, they came across many endermen, therefore thay now have 23 enderpearls and 14 eye of enders. Steve was mining when he spotted stone bricks and mined them. Behind the stone bricks, he found an end portal. He had always heard of them in stories, but he never knew they were real! He then showed Endre the portal. Endre didn't know what to expect because he had no idea what the end portal was or what lies behind it. The finished the portal which left them only two eye of enders left. Then they both jumped into the ominous portal. Steve automaticaly mined through the endstone and reached the surface as Endre slowly followed. When he reached the surface, he spotted many endermen and Steve, attacking a huge black dragon! Endre was terrified and hid under the endstone. Hours later, Steve finnally slayed the dragon, collected the 12,000 experience and left, leaving Endre behind. Endre was still under the endstone, still terrified, and still alive.

    When both Nathan and Endre died, their last thoght, their last wish was revenge. Revenge against Steve for leaving them in another dimension to die. Every minute since their death, their hatred for Steve grows. Now, both of their spirits collided to form the unkillable boss, Eadhen, who is powerful enough to end Steve's life once in for all, so that he can feel the same pain they felt when he left them to die. Eadhen now waits in another dimension called The Dlrowrevo, where they will end Steve's life.
