Superman gets yet another new power
At least it's temporary. Not like he needs a new addition to the arsenal. This is from 1958's SUPERMAN# 125. Story by Jerry Coleman, art by Wayne Boring and Stan Kaye. It's been reprinted a number of times; I read it at an early age and remember being quite intrigued by the ambiguous nature of the little homunculus. Wayne Boring's art is so distinctive and energetic, it remains one of the definitive Superman interpretations. The way he shows the Man of Steel flying in an upright position, "running on air," doesn't make sense but it does feel right.
There has been for decades a certain cycle in the Superman stories. Playing 'can you top this?,' writers continually come up with new tricks he can do and further expansion of his limits. Villains are introduced as more powerful to give him a challenge. When he defeats them as he must, he now has been shown as stronger or faster or whatever than previously. So there's an escalation until you end up with a character who is hard to identify with and difficult to write.
DC then knocks him down a few notches one way or the other. He is reduced in power for awhile and has to struggle for each victory. But then the process starts again, and before you know it he's juggling planets and racing faster than light again. So it goes.
I don't know if there really is a solution to this cycle. Maybe it's not a problem so much as a trait. Adding to this is that, as the flagship character, Superman really can't be outmatched by other super-heroes. Almost by definition, he has to be first among equals. Considering there are enough costumed characters running around to populate a fair-sized town, this keeps him up at Olympus levels.
If it were up to me, I'd just restart DC Comics from scratch every five years or so. Not necessarily with a huge reality-altering event that kills millions and reshapes the universe. Just start over at a certain month with the origin stories and take it from there. Most issues are basically the same tales being told and retold with new faces or little frills anyway.
