Mega Bear vs. The US Air Force -- Part 0 (Introduction)

A bear lumbered through the forest. This was no normal bear -- or maybe it was. You see, this was the most bear-like bear of all the bears in the world. There were no characteristics that were in any way unbearish. In fact, one could say this was the platonic ideal of the bear, except for one thing: no person had ever seen this bear, nor had the bear ever seen a person. It's very difficult to be identified as an ideal if nothing that can think knows you exist.

This changed one day. Hunters saw this ideal bear and, wanting such a magnificent beast for their den, took aim. Smelling something amiss in the air, the bear saw them and, rearing and letting loose the most bear-like of all roars, the hunters quaked. Some primitive part of their brains clicked into place, knowing instinctively what this creature was. This was not just a bear -- this was the archetype of bears, the bear that haunts our collective unconscious, the very bear that has inhabited every nightmare about bears since the dawn of thought. As the hunters cowered, their fear made this bear perfect, ideal, and the universe knew it.

The universe operates on a handful of principles which, for the most part, maintain stability. One important part of this stability is keeping out intruders, crossovers from other, nearby universes, which interact with ours in the medium of thought. When these intrusions happen to occur, as is wont in an imperfect system, there are ways (which deal with the impossible, so we'll not go into that here) the universe's laws will affect it in order to send it back.

This bear was now a being of such an impossibly bearish nature that it was sensed as an intruder, as belonging to the universe of ideals and archetypes. However, this was not entirely true, of course, as this bear, though impossible, really was just a bear; but who's going to argue with the laws of the universe? The bear is torn through the universe, in an attempt to place it into the ideal realm, but it did not fit there. Stuck in limbo, for an infinite amount of no time at all, with no universe to call its own, the bear tore across all the possible universes, all fiction, all history, all culture, all myth, and was spat back into our universe, but leaving behind it a greater trail of damage than has ever been caused before or since. It was no longer just the ideal bear, though; no, it was far, far more than that. As the hunters ran, not knowing what they were seeing, the bear roared a roar not belonging of this world. For this bear was now every bear, a monstrous amalgamation of every bear that has ever been imagined or feared or loved. This was the Mega Bear.
