DC Comics Superman Blue
Superman-Red and Superman-Blue appeared again in a story written by Bob Rozakis and Paul Kupperberg and illustrated by Adrian Gonzales and Vince Colletta and first published in German in Superman Album No. 1 in West Germany in 1981. The story was published in English in 1982 in the oversized Superman Spectacular (an unnumbered one-shot in the United States but published as No. 1 in a series in The United Kingdom.) In this story, red Kryptonite causes Superman to be temporarily split into Superman-Red and Superman-Blue and the two Supermen battle Lex Luthor and the Terra-Man.
The 90s Version from JLA
Anyway, in a 1997 storyline Superman basically lost his powers but, because he’s Superman, of course he developed new ones:
Something odd strikes Superman as his powers begin to fluctuate. A trip to Kandor only seemed to make things worse. Superman found himself as pure energy, needing a containment suit from Dr. Emil Hamilton [which is why his suit looks so different]. Superman’s new form was a blue and white energy being who could still fly (faster than ever) but who possessed far different abilities than those traditionally associated with the Man of Steel. Furthermore, [he could turn his powers off but] when he changed back into Clark Kent, he was rendered powerless.
Superman worked with his new powers and continued to be a hero. He found that he was considerably faster, intangible, and able to interact with computers in this energy form. However, he found that he was weaker to energy disruption, and needed to use his powers creatively to replace the super-strength he formerly had.
While retaining most of his abilities, he could now also sense different kinds of energy, including the trail of radioactivity from a passing van, bolts of electricity and magnetic tractor beams rather than his original heat vision. He was also able to absorb the radiation, although this was incredibly painful.
