A refined version of 'Cão Raivoso,' inspired by DC's Lobo, in a Dungeons & Dragons 5e setting. The character is depicted as a Goliath Barbarian with a more human-like face, long black hair, and a distinct goatee that covers only his mustache and chin, similar to the style in the reference image provided, with the sides of his face clean-shaven. His eyes are a vibrant, glowing red with dark black markings around them, enhancing his intense and menacing appearance. He has gray, stone-like skin, covered in tribal tattoos and scars. He is wearing a torn, rugged black leather jacket over spiked leather armor, with the jacket sleeves ripped off, exposing his muscular arms. His face bears a wide, human-like grin as he laughs, showing normal human teeth. He wields a massive, blood-stained great axe slung over his shoulder. The background is a barren, post-apocalyptic wasteland with smoldering ruins and a blood-red sky, emphasizing his brutal and chaotic nature. The pose should be dynamic, highlighting his powerful and intimidating presence, face inspirad in actor Jason Mamoa.
