Where was I? Oh, yes! Another #SupermanAnalogue of #AstroCity! This time it's Supersonic, and while the name may sound like more of a Flash type (though, we've been over this ), his adventures 100% call back the Man of Steel's. 
Dale Enright was an aeronautical engineer who got caught in a turbine explosion and came out with vast might and durability, as well as an incredible flight speed. In flashbacks we see him having a slew of Silver Age Superman style adventures. However, we meet him long past that.
Supersonic retired after the 80s (and a near death experience), and we find him in the early 2000s a quiet man living in the suburbs. His former government handler calls on him to deal with a rogue robot. And while he takes convincing, eventually he goes on one last ride.
While battling the robot, he reflects in his glory days while lamenting the weakness that age has bestowed on him. It's similar to Secret Identity, reflecting on the limits of power. In the end, he wins but it's messy and not without cost, but still... A wins a win.
Supersonic's tale is a rumination on the limits of virility and the need to feel valued. Does the Man of Steel rust?
