This chapter offers a critical account of some important aspects of sf comics since the late 1960s, focusing mostly on developments in US contexts. It begins by outlining some terminological and conceptual concerns that limit its treatment of the topic. It then focuses on so-called superhero comics, discussing the variety of sf tropes and framing that have characterised the genre formation since the late 1960s and highlighting the impact of historical and social developments can have on superhero sf storytelling. The chapter also discusses superhero comics in relation to political developments and to the different, often conservative or reactionary, politics they can promote, citing examples of super-Cold Warriors, but also antiracist superheroes, and more. It further highlights the impact superhero comics can have on the world outside these texts and addresses their role and impact on synergistic marketing strategies. This is followed by discussions of sf graphic novels and anthology comics in the US and elsewhere in relation to their political messaging. The chapter ends by gathering up these threads into a discussion about how utopian, dystopian and otherwise speculative comics are sometimes used to offer critiques of power, citing feminist, antiracist, Afrofuturist, Africanfuturist and otherwise radical sf stories that challenge the historically common conservative and whiteness-centring frames of earlier sf comics.
