Big G gets done eating Daxam, and now he goes after Earth. The LOSH have about one week to prepare defenses. They also have to deal with The Surfer, who was off scouting other worlds while Big G was taking on 3 billion Daxamites.
How do the following Legion incarnations do against a well fed Big G?
Can they do it without resorting to The Concentrator or Wishing Machine?
FYI, The Concentrator is an old, kind of obscure weapon of last resort that used ALL the energy in the universe for one big attack. While it's in use, there's no power anywhere. Even suns go cold.
The Legion busted it out to stop some asteroids, which is kind of a trivial use of it, if you consider saving a planet at the expense of depowering the entire universe trivial.
