Ok so maybe the villain should be like the endermen king and in the beginning the main actor kills the ender king's ender dragon so the ender king gets made and swears to take revenge, so he sets out to destroy the regular world. His servants would be infected steves (my skin) and he can control endermen so he sends his endermen in to the real world while reviving his enderdragon, and the hero is killing endermen while searching for strongholds and destroying end portals. A bit far fetched, but hey.
