Tropes associated with Margaret McDonald
- Genki Girl: What Sachi, Haruka, and Bontenmaru have in common.
- Nice Girl: Few of the characters she voiced have this personality. Riri and Tamako are borderline while Miho is a full-on straight example.
- Pigeonholed Voice Actor: A large majority of the characters she voices are either overly energetic, good-hearted teenage girls, or young girls.
- Playing Against Type: Nell demonstrates that being cute and adorable does not equate to being a Nice Girl. In fact, it's the opposite.
- Relationship Voice Actor: With Caitlynn French in Tamako Market, Girls und Panzer, Little Busters!, and The Ambition of Oda Nobuna. In all these cases, Margaret is cast as the outgoing and friendly character, while Caitlynn is cast as the quiet and more reserved character in a Red Oni, Blue Oni pair.
- Star-Making Role: Miho from Girls und Panzer.
- Token Mini-Moe: She's slowly filling her resume with these characters. Examples include Riri, Mei, and Bontenmaru.
