Shot in the Dark

Before there was Dezra and Before Sam and Dean there was John and Mary. The future parents of Sam and Dean had fought against an extraterrestrial enemy bent on destroy the worlds and alternate realities, but it was through their quick thinking and fast instincts were the Winchesters able to defeat them, or so they thought.

Now years later, the Akrida are back and out for revenge on the Winchester family. But they seek a new host for their plan of world dominance. It's now up to Ezra and Mary to put a stop to it like their relatives before them. Will they be able to do it? Or would they be risking their lives against an enemy that is so powerful it can mimic other monsters?
