This article concentrates on the comic “Attack of the Hideous Space Varmints” (1997) by Disney artist Don Rosa. The comic deals with Earthlings who invade the territory of one-eyed aliens. The aim is to study Rosa’s comic from a parodic perspective: how Rosa uses science fiction tropes characteristic to the 1950s cinema and comics and ridicules them. My methods consist of close reading followed by formalist comic analysis. While doing so, I also utilize the concept of metalepsis. The analysis will be supported by theoretical works on science fiction and the postmodern view of parody. One important source is Kimmo Ahonen’s recent doctoral dissertation concerning invasion films that offers background material concerning the societal conditions and the era in the United States that Rosa utilizes in his comic – the 1950s. The article offers a new perspective on how funny animal comics as a narrative form can discuss the themes of invasion and “the Other”, and present them both in a parodic manner. The aim of the article is also to suggest that the whole subgenre of Disney comics should be more comprehensively introduced to the field of comics studies as a serious research topic.
