What heroic qualities are anti-hero, Seth Gecko, lacking?
Antihero An antihero, or antiheroine, is a protagonist who lacks conventional heroic qualities such as idealism, courage, or morality. These characters are usually considered "conspicuously contrary to an archetypal hero". Although antiheroes may sometimes do the "right thing", it is often for the "wrong reasons" and because it serves their self-interest rather than being driven by moral convictions.
Science hero Science hero is a term coined by Alan Moore in his work for America's Best Comics to describe fantastic heroes. This includes those that have a science fiction explanation for their powers, as well as magical and non-powered characters. The term is used extensively throughout the ABC titles, especially in his police procedural series, "Top Ten", as well as in "Terra Obscura". The term is a nod to the pulp heroes.
