Book excerpt: Super-Girls of the Future: Girlhood and Agency in Contemporary Superhero Comics investigates girl superheroes published by DC and Marvel Comics in the first two decades of the twenty-first century, asking who the new-and-improved super-girls are and what potentials they hold for imagining girls as agents of change, in the genre as well as its socio-cultural context. As super-girls have grown increasingly numerous and diverse since the turn of the millennium, they provide an opportunity for reconsidering representations of gender and power in the superhero genre. This book offers the term agentic embodiment as an analytical tool for critiquing the body politics of superhero comics, particularly concerning youth, femininity, whiteness, and violence. Grounded in comics studies and informed by feminist cultural studies, the book contributes a critical and hopeful perspective on the diversification of a genre often written off as irredeemably conservative and patriarchal. Super-Girls of the Future is a key title for students and scholars of comics studies, visual culture, US popular culture, and feminist criticism.
