One of my earliest WTF? moments in comics came while reading an old reprint of Adventure #312. The Legion are searching the galaxy for possible cures for death, just on the off-chance that someone's come up with a resurrection potion or something and not bothered to mention it to the rest of the universe.
Oh wait, I didn't mean death exactly. You see although Lightning Lad has been worm food since issue #304, they think he may only be mostly dead, which is a little bit alive (1), but rather than hooking him up to a life support, they seem to think he'll keep fine as he is. So Superboy goes off to investigate this planet where the people periodically fall into a state of death-like coma but then recover a few hours later. It's a condition that resembles what is known on 21st century Earth as sleep, barring the odd custom of this planet, where, rather than curling up in the comfort of one's own bed to lose consciousness, people of this world prefer to lie in perspex coffins out in the street.
After several more investigations by the six members of the Legion who are taking part (2) we find that Mon El knew a solution all along, which he demonstrates by having an android sacrifice itself to revive another android. I can't decide whether this is callous or idiotic. Either the androids are sentient lifeforms, in which case making one kill itself purely for demonstration purposes is reprehensible, or they are not living creatures and the demonstration is pointless (3).
So by a contrived quirk of plot, the only way to bring Lightning Lad back is by sacrificing one of our heroes. Except not. Because it turns out any old life form would do, as Chameleon Boy's expendable pet heroically bites the dust, only to be replaced by an identical copy a few issues later.
I'm not sure my brain can cope with attempting to explain the plot of Adventure #313, but I'll try. In a tortuously convoluted plot, Supergirl travels to the 30th century for one of her rare appearances in the Legion, but as she arrives she bumps into some red kryptonite that knocks her out and splits her in to two people. The first Supergirl to wake up decides that she wants to live a life of her own and not be rejoined when the temporary effect wears off.
She devises a plan where she believes that she can siphon off the "red kryptonite effect" from her body and, rather than just dump it in empty space, for no very obvious reason she has to use it to irradiate other people, and because deep down she has a death wish and wants to be found out, instead of picking on some defenceless nobodies in the back end of the galaxy, she uses it on the people best equipped to stop her; the Legion. And just to make sure that they won't be badly impaired, she only uses it on the female members (4) except for the other Supergirl, even though she's the only person present actually vulnerable to any form of kryptonite, and the only one putting up any resistance. And just to make sure everyone knows she is the villain, she calls herself Satan Girl.
Unfortunately it takes the Legion awhile to get organised because even the robot-nurses of Quarantine World are unable to tell the difference between radiation poisoning and a virus, and by the 30th century they have yet to invent a device that can detect kryptonite radiation.
In the end Supergirl devises a plan that involves travelling back in time to get some help, but rather than grabbing Superboy, Superman, or any other male hero (5) available to them in all of time, they go collect Streaky the super cat (6), Krypto, and other assorted super pets for an entirely superfluous guest star role as they don't achieve anything more than Supergirl was already doing solo; keeping Satan Girl busy until her time (7) ran out.
Does this story make sense on any level at all? I'm thinking not.
Adventure #314 has one of the funniest moments in the whole volume. Villainous Alaktor steals a Legion time machine and does a kind of evil Bill & Ted, collecting Nero, John Dillinger, and Hitler to help him do some bad thing or other. So he picks up the most despicable people in history he can think of, and then gives them super powers. And then they tie him up and go and do whatever the hell they like.
The pure comedy moment is the hurt look on the face of the naive villain when he finds he is being betrayed and whimpers "But you promised!"
It cracks me up every time.
1) If you didn't get the Princess Bride reference, shame on you.
2) presumably the rest of the team just didn't care enough to take part
3) It would have worked better with chickens
4) though interestingly, the male legionnaires contribute little if anything; this is very much a Supergirl story
5) remember as far as they are aware, only females are susceptible to Satan Girl's radiation virus
6) presumably having forgotten about Streaky's telepathic descendant Whizzy
7) which they didn't know about
