Advances in science and techlogy longer change how we live, they determine it. In the t-too-distant future, tech-scientific developments may make individuals stronger, smarter, healthier and more productive-but to what end? Addressing this question, speculative fiction has created an abundance of transhuman characters, protagonists with extraordinary strength, intelligence or abilities. Often they are antiheroes, openly rejecting-or rejected by-society and acting on immoral or extreme principles that challenge readers to approve, condemn, excuse or explain. This study explores the antihero of speculative fiction as a paradoxical blend of human and transhuman. These protagonists illustrate the dynamics among the individual, tech-scientific development and societal rms, and blur distinctions between human and machine, biology and techlogy, right and wrong. Fictional works covered include Mary Shelley's Frankenstein (1818), Olaf Stapledon's Odd John (1935), Alfred Bester's The Stars My Destination (1956), William Gibson's Neuromancer (1986), Alan Moore and Dave Gibbons' Watchmen (1986-1987), Richard Morgan's Takeshi Kovacs trilogy (Altered Carbon , Broken Angels  and Woken Furies ) and Black Man (2008).
