therightchoiceI've been given the okay by the mods, so I can finally give you a nightmarish version of all those toy movies I've grown up watching, like Toy Story, Small Soldiers and Toys.
You see this kid? He's the Antichrist and he's one of the more powerful god-mods in Supernatural, a canon that has more god-mods than you can shake a staff of Moses stick at. One of his powers is reality-warping, so whatever Jesse wants, Jesse gets. The thing is that he can't control it. It's something that never occurred to Jesse and he just doesn't know how it really works. So he's been practicing, with telekinesis at first. Eventually he's going to at least try his hand on his reality warping powers. And how he does it?
With toys, of course.
Jesse will be buying a few figurines - mostly cheap animal ones and he will switch from being toys to real live animals and back to toys. And for a while, it will look like that he has mostly mastered it. But then the Core fucks it all up for the poor Antichrist.
From September 3 to September 6, these toys coming to life will be utterly random times. Animal figurines and stuffed animals will turn into actual animals.There will be herds of horses galloping down the city streets, or tigers will be stalking in someone's house. Thousands of cars, trains, planes, even military vehicles will appear, usually outside someone's house. Adoption agencies and child services will be overrun with thousands of suddenly appearing squalling infants. Action Figures will turn into real people and, depending how they were created and marketed, these figurines will go on doing things that they were preemptively thought they will do in "their" storyline. Think G.I. Joe and the Cobra Organization toys suddenly having actual bodies and start doing what they were meant to do - beat the shit out each other, guns and all. Violence will break out between gangs that police has never heard from before. Heck, even boardgames aren't immune - your house or apartment can become Siren's Pull's version of Mouse Trap, or you might have to fight for your life in a game of chess, like in Harry Potter!
Because these are happening randomly, Jesse wouldn't be able to connect the dots just yet, so he will continue practicing.
On September 7, all hell will break loose. It will be all the toys turning to life, from every self to every child's playpen. It can be amusing and harmless, like having a sudden collection of kittens. Or it can be extremely deadly like a sudden alien invasion to a kindergarten school in Sector 3. It will be utterly chaotic, and it can be liken to a war zone, depending on the toy.
At around the late afternoon, when Jesse realizes what is actually happening, he will revert everything back to normal. He won't be able to return any of the dead, but he can revert the injuries done on the NPCs and to your character. If you don't want that to happen, just let me know! Go wild with this plot!
As a note, while I gave G.I. Joe as an example, actual toy franchises aren't allowed to be fourth-walled. But you can make up your own if you like!
EDIT: Just for reaffirming and clarifying behind the scenes of this event: Around August 29/30, Jesse will be accidentally Hulking out Bruce Banner with his powers, and as a result Jesse's powers almost immediately turned Hulk into a toy as a defense mechanism. (This will be all handwaved, fyi.) From August 31 to September 6 Jesse will be focusing nearly all his energy in turning Bruce back to normal, so he won't be doing much of watching any network posts, let alone responding. On September 7 does the toy problem finally takes his attention and he will change everything back to normal, and will eventually be able to de-toy Hulk and bring him back to Bruce Banner.
