A dark, menacing Minecraft-style boss dragon. Large wings made of shadow, glowing red eyes, obsidian-like black scales with purple accents, long spiked tail, blocky body and limbs inspired by Minecraft mobs. Style should be low-poly, cubic, voxel-like. The model should look ancient and powerful, like an ender dragon corrupted by dark magic. Designed to be used in a video game. No background, clean silhouette.
