This study analyzed 312 avatars used by adolescents in 5 general chatrooms to understand how gender is represented. Most avatars were humanoid (92.3%), with 46.2% female and 32.1% male. Female avatars commonly featured coy gazes (75%), exaggerated features (36.8%), and revealing clothing (50%). Male avatars commonly depicted baggy clothing (35%), obscured eyes (33%), and action figures or weapons (40%). Both genders used combination avatars. Unknown gender and non-human avatars mirrored male categories. The findings suggest avatars represent ritualized gender roles and ideals, with females emphasizing submission and males emphasizing masculinity and anonymity.
