The Battle With The Eradicator Gets Weird in 'Superman' #6
Superman and the Eradicator have an epic fight on and around the moon in Superman #6, by Peter Tomasi, Patrick Gleason, and Mick Gray. Superboy --- that is, Superman's son Jonathon Kent -- is also on hand, although he wisely gets out of the Eradicator's way, and Lois Lane is there too, but this is the Lois that's Superman's wife and Jon's mom, not the one who became Superwoman. Mind you, she does have some Batman armor that enables her to survive in space. There's a lot going on here, clearly.
