This did not actually happen in the series but is an alternate future in the possibility of Jackson & friends losing the Final Battle.
After The Battle ch 1
After the battle Jacob Minch, Pete, Harvey, and Billy Larry took over the world. They had the Voldemorigami to do a spell that destroyed all adults. Me and my friends went into hiding. But Abigail, Olivia, Zack, Mike, Tom, Tommy, Zach, Kellen, Sara, Gavin, Ashley,DT, Ben, Jake, Jon, and their origami were captured. The only hope was me, Sam, the apprentices, and our army of origami. If you don’t know the aprentices are fourth graders that we’ve been training in the ways of the origami.
