I only watched an episode or two of this one, so I can't recall a whole lot about it. The protagonist is a former astronaut of some sort, who makes it his mission to clean up the crime in his city. He might have been a police officer in his "new life" or he might have decided to become a sort of quasi-superhero. In either case, I distinctly recall his space suit being the gimmick that makes him an effective crime fighter in the show. I seem to recall the protagonist being a young, dark-haired man, and I think he had a friendship or an alliance with a young woman (maybe a fellow cop, or someone from the space program?). I don't think there were alien beings in the show. The criminal threats were all quite terrestrial, IIRC.
Timeframe and other Publication Details
This was a syndicated tv show I saw on American television, probably around the late 90s to early 2000's. I believe the show was filmed in Canada, though I'm not certain. I don't think it lasted very long - it was pretty dreadful. I can say for certain the show is not Space Cop or Gerry Anderson's Space Precinct.
