Lightning Genasi (5e Subrace)
From D&D Wiki
Lightning genasi differ from typical humans with their blueish skin that ranges from close to white to a midnight blue, entirely hairless they have similarly colored crystalline growths that protrude from their head but can also grow from their back, shoulders, elbows and knees. Beyond that, the faint smell of ozone eludes from them, and the stronger the scent the greater their current emotion, the hairs of other creatures standing up from their heightened electromagnetic field.
