Create an orc boss called the Bonecrusher Tyrant in A-pose, a hulking figure with dark green, scarred skin and spiked armor fashioned from scavenged metal. His left arm is encased in a massive gauntlet covered in glowing red runes, and he wields a bone-crushing flail with spiked iron balls. His tusks gleam, and his savage grin reflects unrelenting ferocity. Render in ultra-detailed 8K, photorealistic, Unreal Engine-ready, trending on ArtStation, flawless, Masterpiece
