This thesis examines the themes of characterization of the character Sasha James and Not-Sasha within the media text The Magnus Archives, as well as which of the themes can be seen reflected in the visual paratextual works created by the audio dramas fan community. This is to examine what influences the visual representation created in paratextual work when the media text from which the visuals take inspiration lacks visuals and description of characters. The thesis employs a thematic-analysis approach and monster theory to understand how the horror genre and the monstrous narrative of Sasha James have helped inspire the visualizations. The result presents three themes of Sasha James' canon narrative that have impacted the visual paratextual work created by the audio dramas fan community: The “real” Sasha, Not-There, and wit. The themes showed how fans approached the subject of the monstrous body within the paratextual work by presenting a version of Not-Sasha with easily identified monstrous features, but also their willingness to employ the monster’s wit to visualize it as a humanoid version, working as a parallel to Sasha James.
