Many of the tropes of science fiction can be viewed as similar to the goals of transhumanism. Science fiction literature contains many positive depictions of technologically enhanced human life, occasionally set in utopian (especially techno-utopian) societies. However, science fiction's depictions of technologically enhanced humans or other posthuman beings frequently come with a cautionary twist. The more pessimistic scenarios include many dystopian tales of human bioengineering gone wrong.

Examples of "transhumanist fiction" include novels by Linda Nagata, Greg Egan, Zoltan Istvan, and Hannu Rajaniemi. Transhuman novels are often philosophical in nature, exploring the impact such technologies might have on human life. Nagata's novels, for example, explore the relationship between the natural and artificial, and suggest that while transhuman modifications of nature may be beneficial, they may also be hazardous, so should not be lightly undertaken.[1] Egan's Diaspora explores the nature of ideas such as reproduction and questions if they make sense in a post-human context. Istvan's novel The Transhumanist Wager explores how far one person would go to achieve an indefinite lifespan via science and technology.[2] Rajaniemi's novel, while more action oriented, still explores themes such as death and finitude in post-human life.

Fictional depictions of transhumanist scenarios are also seen in other media, such as movies (Transcendence), television series (the Ancients of Stargate SG-1), manga and anime (Ghost in the Shell), role-playing games (Rifts and Eclipse Phase) and video games (Deus Ex or BioShock).

The science fiction film genre has always had a hand in exploring transhumanism and the ethics and implications surrounding it. In the first two decades of the twenty-first century, however, there has been a surge of films and television shows focusing on the superhero genre. There are many superheroes whose stories are propelled or entirely result from dealings with transhumanism. From The Incredibles, to Iron Man, to The Batman saga, there have been plenty of heroes who did not receive their powers naturally, and therefore represent the great leap human beings may take into improving their own condition. Additionally, because these films represent the most popular trend in the medium today, they indeed represent a glimpse into the ideological shift of western culture as a whole. The fixation on normal men and women improving themselves artificially seems to have become a very widely accepted and celebrated idea.[3]
