Man, those are some beefy superheroes about to square off there! Superman's musculature in particular makes my head hurt.
The Story: "Crisis in Tomorrow!" by E.Nelson Bridwell, Martin Pasko, Dick Dillin, and Frank McLaughlin. Concluding the story from the last two issues, we open here with the two Flashes, the two Green Lanterns, Ibis, and Mercury taking on the giant Earth-S baddie Mr. Atom!
As they take him on, gravity itself starts going haywire, sending people into the skies. The Lanterns track down the source of energy doing this, which leads them to a spaceship under the command of Brainiac!
They defeat Brainiac and Mr. Atom, meanwhile Superman, going after King Kull, gets possessed by Kull's chunk of red kryptonite, which turns him mad. Uh-oh!
Johnny Thunder, who went out to round up Billy and Mary Batson and Freddy Freeman, calls in his T-Bolt to help transform the kids into the Marvel Family(since Shazam is under the control of Kull and can't do it himself), who then attack Kull and free the other Gods Kull was controlling.
The Lanterns, trying to control Superman, are failing, so Captain Marvel takes on the job, and eggs Superman on to paste him one! Superman heads towards Marvel like a rocket when, at the last moment, Billy says his magic word, which hits them both(shades of Kingdom Come!), returning Superman to normal.
They apprehend Kull, and return to their individual Earths. Wow, I'm exhausted.
Roll Call: Superman, Flash, Green Lantern, Hawkman
Notable Moments: The cover is a bit of a cheat, since the fight never occurs, but I guess it's ok. It's really a cheat to have the individual heroes rooting for one hero over the other, which never happens at all. (I notice Flash and Green Lantern are not taking sides; I guess they're the super-delegates of the JLA)
I cannot imagine the effort Dick Dillin must have had to put into this story. And to make matters worse, the letters page advertises that issue of Strange Sports Stories, on sale at the same time, that featured like a million characters and was also drawn by Dillin. Ye gods!
