In a sprawling urban city, a talented hacker tries to steal from a MegaCorp, but gets caught. The company owner sways the hacker to his side with promises of wealth. Together they hijack and weaponize a satellite and, with the hacker posing as a member of the military-industrial complex, they even try to use a narcotic-based poison to bring down a crusading hero who stands in their way. During their plan to build a giant supercomputer, one of the corpos is turned into a killer cyborg. The hacker ends up leaving the MegaCorp and helping the hero.
Okay, Superman III isn’t actually cyberpunk enough to be called cyberpunk, really. But I’ve amused myself by referring to it as such before and I’ll probably do it again.
What I will say is that the hacker character in the movie, Gus Gorman, should come back. I say we keep him as close as possible to the character as seen in the movie. He’s talented with computers but has trouble making his way in a corporate world, so he does thing underhanded now and then. He probably came afoul of Superman at some point, but Superman can tell that prison isn’t a solution, so he and Gus become allies. Sometimes Gus’ll get in over his head and maybe some criminal types will want to harm Gus, so Superman can save the day. There are definitely times when Superman (or Lois or Jimmy or anyone) might need the aid of a hacker, so he can be brought in for that stuff. I’d be wary of making him a clean-cut good guy, but in a world where Superman is a champion of the oppressed, Gus would be on that list.
