One of the more prominent features of the Héroska is their tusks, whose purpose has generally been agreed to have developed to their current extent due to sexual selection, though some speculate this may have gotten its start to assist in the shaving of tree bark for consumption. This earlier, heavier reliance on plant matter is still exhibited today in their robust jaws and temporal muscles and their more prominent sagittal crest for improved muscle attachment.

Their stature is larger on average than humans, ranging from roughly 175 cm to 220 cm. This coincides with more significant bone and muscle density, aided by a larger heart and a more robust cardiovascular system. In addition to their size and musculature, the Héroska display a wide yet consistent range of external physical traits. Skin pigmentation most commonly presents in muted earthen hues, including deep forest greens, weathered tans, rich browns, and cool greys. These tones are often unevenly distributed, with natural mottling, darker patches along the shoulders, spine, and limbs, or subtle gradients that deepen with age and prolonged sun exposure. Scarring is common and tends to fade slowly, often remaining visible for decades due to the density of the dermal layers.

Hair color among the Héroska is predominantly dark, with black being the most widespread, followed closely by deep browns. Hair texture varies from coarse and straight to thick, tightly coiled curls, frequently growing heavier along the scalp and nape while thinning across the temples with age. Facial hair is common in many populations and follows similar coloration, though streaks of grey or ash-white often appear earlier than in humans, particularly in individuals exposed to prolonged stress or harsh climates.

Eye coloration is typically dark, ranging from black and deep brown to softer hazel tones. Gold eyes are exceptionally rare and are often regarded with cultural or spiritual significance, sometimes believed to be indicative of ancestral favor or unusual lineage.

Héroska lifespans roughly the same as humans, living around 70 to 80 years under ideal conditions, but even among the nomadic Dalro these ages are commonly reached. By 18 years of age, Héroska tusks are generally expected to stop growing, but this growth can persist well into adulthood; a holdover from a time when they relied more heavily on them for the acquisition of food.
