The Story: "Where On Earth Am I?" by Cary Bates, Elliot S! Maggin, Dick Dillin, and Frank McLaughlin. We open on Earth-Prime("our" Earth), where we find JLA editor Julius Schwartz berating his young writers--Bates and Maggin--for not being able to come up with a plot for this month's issue!
While Julie goes to lunch, the boys break out Julie's Cosmic Treadmill(as seen in The Flash #179), and Bates accidentally finds himself transported to Earth-2! While there, something mysterious happens to Bates, where he finds himself with amazing powers, and becomes tempted to use them for evil!
Meanwhile, Maggin tries to follow him, but ends up on Earth-1, where he is rescued by Aquaman from drowning, who takes him to the JLA satellite, where he gives them his story.
They of course don't believe him, but Maggin has developed powers too, which he uses to prove to the JLA he's not making up this crazy story, by teleknetically removing the masks and knowing the secret I.D.s of several JLAers!
On Earth-2, Bates gets worse, and uses his powers to trap and defeat the JSA. We then find out that this is because the evil supervillian, The Wizard, cast a spell on Bates turning him evil!
The JLA come to Earth-2, and are met by the Wizard and his Injustice Society(Sportsmaster, Huntress, The Gambler, The Shade, and The Icicle). Luckily, the JLA defeats them, but finds that these bad guys are actually...the JSA! What's going on here? Only the evil Cary Bates knows for sure. To be continued!
Roll Call: Batman, Aquaman, Flash, Green Arrow, Hawkman, Black Canary
Notable Moments: Another lark of an issue, similar to #89 where writer Mike Friedrich was the protagonist. What was it about the JLA that made their writers want to incorporate themselves into the stories?
