As with many of Jim Shooter’s stories from this period, the first half of the two-parter had introductions and set-up, while the second half, in Adventure 355 (April 1967) has the bulk of the action, again rendered by Curt Swan.
The Legion of Super-Villains bring two members into their team for this, Beauty Blaze and Echo. Neither would really return, although Echo made a cameo in a Legion story from the 90s, and in the 80s Flare joined the Fatal Five, a woman with powers identical to Beauty Blaze.
They divide and fight, along the usual lines: Lightning Lad against Lightning Lord, Cosmic King against Element Lad, and Saturn Girl against Saturn Queen.
Beauty Blaze us quickly bested by Polar Boy, and Echo falls to Cosmic Boy.
But it turns out that the villains the Legion were fighting were all illusions, and the real group is holding Brainiac 5 hostage below the sea.
In the end, the day is saved by two masked figures who reveal themselves to be descendants of Mr Mxyzpylk and Lex Luthor, who join the Legion. Neither of these characters ever appeared again, and though I enjoyed the story as a child, the ending does feel weak.
There is a second story in this issue, which sees Lana Lang attempt to join the Legion in her Insect Queen identity. It’s Curt Swan art again, but the story is by Otto Binder.
She gets rejected because her powers come from her bio-ring, rather than being innate, but she gets to accompany them on a mission anyway. Dream Girl warns her that she has seen disaster for Lana if she takes on the form of a moth, which of course happens eventually.
After briefly losing her bio-ring, it is returned by Superboy, who “didn’t know” he had it in his cape. Right.
But as she saved Shrinking Violet and Sueprboy during the course of the adventure, she is rewarded with honourary membership, and does make a couple more appearances with the team.
