In this article, we describe a year-long superhero storytelling project we facilitated with youth in a midwestern middle school. In this project, students read "Miles Morales: The Ultimate Spiderman," designed superhero stories set in their community, and presented artistic representations of their stories to their families and peers. We present three episodes of mobile storytelling from this project, focusing on Aidan, one of eighteen youth participants. Using tools from theories of transliteracies and critical imagination, we illustrate how Aidan's embodied movement and play constituted critically literate acts. A transliteracies lens oriented toward critical imagination reveals how Aidan fluidly moved between fictional and real worlds to reimagine his experienced realities. These findings indicate a need to expand what counts as literate activity in schools.
