It's been a minute, due mostly to the craziness of the world. However, I've been at work, mostly listening to @LarryTye's book on Superman on audible. So even though this #SupermanAnalogue wasn't brought up, it's a bit of trivia that I've always meant to bring up: Power Man! 
Power Man appeared in a story where Superman was threatened by Kryptonite, but he didn't want to risk Batman and Robin's lives. Instead, he deployed a robot to act as his surrogate, disguised as a new hero. While he couldn't fly, he was plenty strong and able to handle shit.
Since this predates the Superman Robots... I should discuss them... It can be seen as a prototype. He wouldn't be seen again save for as references like in Kingdom Come.
As a literal stand in for Superman during his more dangerous adventures, Power Man is a memorable figure from a period when there weren't that many Superheroes. This was the 50s in the stretch between the Golden and Silver Age. Now, he is notable for his design and as trivia.
