so the blurb for issue #43 says:
"While Science Police search parties ransack The Legion's headquarters, two away-teams of Legionnaires fight like cornered wolves against vicious enemies. Meanwhile, Brainiac 5 sells out the Legion's greatest secret! New villains, stunning action and the LSH is shut down!. Plus, the introduction of Ikilles and Cazhmir! The Ikonns! The Peril Men! And more!"
so lets all guess what this secret could be! (or could not be...)
1) Imra's a Skrull
2) Querl has Superman-boy flash frozen in the basement
3) Legion of Super Chimps
4) they're all CLONES
5) WHAT? BUT THE LEGION DIED TWO YEARS AGO, THAT MUST HAVE BEEN A GHOST.
6)that they've totally forgotten about looking for Cos.
7) garth's hair care secrets
