Iris appears as a petite human woman with a mass of curly hair typically secured by a scarf or headband that allows it to pouf out when let loose. She has a small build that makes her loud voice notable, and her face shows a range of emotions from worried and pinched expressions to disgruntled looks, fuck-you smiles, furrowed brows, and hopeful relief. In challenging environments, she dons an environmental suit with a helmet through which her sweating face can be seen, and she carries small sidearms while displaying anxious body language with folded arms.
