When we last left the JLA, the Flash was brrzzapped unconscious, Superman was banished off-planet by a court order, Green Arrow was captured by a quartet of british-biker-garbed Livergoons (who, despite their outfits, talk like the Bowery Boys, non-stop), and Batman (who beats the crap out of the Livergoons who capture GA, because he's Batman) has been ray-gunned into submission.
He's lying, by the way;
because he's not only a villain he's a cheapskate, and lying is cheaper than bombs.
That (now revealed) villain, in case you don't recognize him from behind is none other than :
We agree with you completely, Flash.
The Headmaster. Another powerless, ugly, and idiotic JLA villain brought to you by Gardner Fox and Mike Sekowsky. Actually his full name was "Headmaster Mind" in his original appearance four years before this, but by this point he seems to have lost his "Mind". So to speak.
"Vanquisment" really is a word; I had to look it up to make sure.
His plan is to frame the captured heroes for crimes committed by costumed Livergoons and then dump the real heroes corpses nearby afterwards claiming to have killed them, which will then make him popular enough to be elected dictator.
This plan took him four years of careful planning. This is why you probably haven't heard of the Headmaster. He's the in-universe equivalent of Zack Snyder, since his plans depend on making the world hate and mistrust DC's greatest heroes.
That's a better grade than the writer gets, GA!
Add 'crumbiness' to the list of 1001 Ways to Defeat Green Arrow. One nice touch to this plan, though. It does give the villain a reason not to kill the heroes right away; he needs their corpses to be fresh for later, or the frame up won't work. I mean, at least, that's what I am deducing; he doesn't say that or anything because that would make too much sense.
Anyway, obviously the Headmaster's plan is *ahem* foolproof. So what can possibly save them...!?!?!
Don't worry, because the one thing that can save them is currently flying to their rescue:
This is for you, Damian. It's all for you.
THE ATOM'S UNDERCARRIAGE!
