Mascots are villains who are commercially popularized and associated with a series or franchise. These villains range from being a figure of a media like music and food products (such as Eddie the Head to the band Iron Maiden) or to a Big Bad of a series like Magneto and The Joker.
To qualify, the villain must have some affiliation with a series so closely that fans or followers expect at least cameos or mentions in any given installment.
