The Story: "War With The One-Man Justice League!" by Len Wein, Dick Dillin, and Dick Giordano. Continuing the story from last issue, we rejoin he JLA in their satellite, having lost their powers due to the machinations of the mysterious Libra.
The rest of the JLA shows up, and its the Atom who suggests using Amazo to return the heroes' powers. They rewire him, and Black Canary even takes the time to redesign his costume! The plan is to trick Amazo into chasing the JLA, causing him to attract the molecules Libra stole from the JLAers that contain their powers.
Amazo first takes on The Flash, Elongated Man, and Black Canary, and then Superman, Aquaman, and Green Arrow, and everything goes according to plan. Except that Batman--even operating at half his intellectual power--figures out a flaw in their plan!
After Amazo runs into Green Lantern, Red Tornado, and Atom, he figures out their plan, since he has half of Batman's smarts. Luckily. Bats figured that out, too, anf finds a way to hit Amazo with a blast of energy which drained all his powers, making him little match for the Dark Knight Detective.
Roll Call: Superman, Batman, Aquaman, Flash, Green Lantern, Green Arrow, Atom, Black Canary, Elongated Man, Red Tornado
Notable Moments: There's more to this story than what I outlined above, but I found it peculiarly difficult to summarize. The plan to use Amazo is complicated, luckily the JLA had the Atom and Batman working on it.
This issue comes with a two-page "Amazo and His Creator" feature, featuring panels from previous Amazo stories, a JLA crossword, another Seven Soldiers of Victory reprint(Part 2 of "Beware! The Black Star Shines!", from Leading Comics #2), a Starman solo story, "Starman's Lucky Star!" from Adventure Comics #81, plus "The Super-Exiles From Earth!" from JLA #19.
But that's not all! There's also a separate letters page all about Hawkman's resignation from the JLA, called:
...first Watergate, now this!
This same month, over in Wonder Woman, began the multi-issue storyline guest-starring the individual members of the JLA as they put the Amazing Amazon through "trials" to see if she, now that she had her powers back, was up to rejoining the JLA.
To be perfectly honest, I had zero interest in digging up all these issues of WW, since I always found reading a solo Wonder Woman comic generally a tedious experience (no offense to the fine folks who worked on her book over the years). But it was an unusual and impactful storyline, so it deserves some mention, so here are the covers to the issues:
...as you can see, each then member of the JLA got a shot, even the Red Tornado(though he got pared up with The Phantom Stranger)! The series, of course, culminated in Wonder Woman rejoining the JLA, which we'll get to in a few weeks.
