OK guy's heres a short explanation , I'll be talking about a movie as well so spoilers ahoy.
OK
Now has anyone seen Pulp Fiction , I'm sure someone has. Well anyway theirs much speculation over what is in the attache case when someone asked Tarantino directly he replied with "It's a Macguffin" (Well actually he would have replied with something like "Jeez it's a ****in plot device idiot" *slaps the guy upside the head*)
A Macguffin is a part/object that no one is ever 100% sure about and drives the plot along. Ergo it's transformation from a simple mind control equation into this overblown crap that it is now.
meh darkseid said that even a little of its power he could bring his reality to its knee's some say he ment the fourth world and others ment he thought the entire universe, also it destroyed a solar system i believe with not much as a flicker of power, it took the combined powers of darkseid, dr fate, and mordru i think im not sure about etrigan, maybe highfather, but anyway these guys combined where said to have the power to destroyer whole realities but this still wasnt enough for the ALE entity to be defeated.
