Its prominent features include two heads with shimmering copper-colored tops, each adorned with piercing eyes that radiate a brilliant green hue, evoking an air of mystical allure and dangerous beauty. The dual heads grant the Osibrazius heightened awareness of its surroundings, enabling it to track prey from multiple angles and coordinate its strikes with deadly precision.
