Action Comics # 296 (Source Comicvine.com)
9. Ant-Man Superman
Let’s talk Red Kryptonite!! Most everyone knows what green kryptonite does (Hint: It makes Superman super dead), but not many know about the various other kryptonite colors and what they do. Red Kryptonite is my favorite, being the weirdest one of all. Red K mutates Superman in inconsistent ways, all with different effects, based on whatever the writer wants them to be.
In the issue we’re gonna talk about, giant evil space ants show up on earth (it is a Tuesday in the DC Universe, after all) and kidnap Lois Lane. Because Lois is just the most kidnappable human being in the entire history of kidnapping.
Superman flies through a Red K cloud and mutates, giving himself an ant head. Because this is a comic book. He then flies back and talks to the ants who, it turns out, are trying to warn earth about nuclear destruction, because they care, for some reason.
Superman listens to some giant ants PSA him a bunch and then goes to talk to the UN. The giant ants repair their spaceship and go home.
That is a sentence I just typed.
