The role of warrior, even hero, has the been the role with the greatest amount of attention. Giant robots are seen as being armored, powerful, and serve as warriors instead of the frail humans, which would thereby reduce the danger that humans face. However, with all sides eventually armed with robot warriors, the trend is that the warrior robots are built larger, and with ever growing ability to destroy an opponent. The world of giant robots seems pure, just metal fighting metal, but, the war from remote control does have other consequences. These are civilian deaths, and there is a notion that, since the robots fight in human stead, are these robots heroic, or are they murderers, or, are they still but machines?
Comics have presented some exciting stories, many have a relation to being influenced by or created by Japanese writers/artists/comics. Go Nagai might have created the template for Giant Robot stories, but, there have been many different aspects of the genre/subject matter.
Neon Genesis Evangelion is nearly all metaphor and direct allegory, but the rest of the comics shown tell a straight forward story of giant robots, as heroes, as villains.
“Is this neuro-bot really supposed to be her, this creature, this thing, compiled of the ghosts of human data, the replicas of their past?”
