Undyne, the head of the Royal Guard. The toughest person you’ll meet in the Underground. Despite her harsh outside, she’s not just mean for the sake of being mean. She sees potential in everyone, and always does her best to help them improve. She’s not trusting of our protagonist in the beginning, but that just might turn around. (As mentioned in the description, it really comes to nailing her booming voice and her sentimental moments and their difference from each other. Make sure to record two or three takes of each line.)
