Tighnari is an astute and knowledgeable man who is part fennec fox, identifiable by his large, sensitive ears and a tail that wags slowly. He has black and green hair and teal eyes. Though typically calm, he can be stern, stubborn, and sarcastic when annoyed, often cursing. He's a workaholic, well-versed in botany and biology, but also likes to tease. He gets nervous easily, which he shows by tapping his thumbs and letting his ears droop. Tighnari is also chronically gassy and struggles to control his bubbly farts.
