Friday the 13th Equestria Girls

Sunset brings Twilight and Spike with her to investigate a nearby cave kept off-limits by Timber, where they find a deposit of geodes infused with Equestrian magic. The three are confronted by Gloriosa, who reveals herself to be the true cause of the magical incidents. Sunset learns through her visions that Gloriosa, desperate prevent the camp's imminent foreclosure, has been wearing the geodes as a necklace to harness their magic in attempts at improving the campers' experience; Timber, disapproving of her reckless actions, invented the story of Gaea Everfree to cover for her.

Gloriosa adds more geodes to the necklace and is corrupted by their power, taking on an appearance resembling Gaea.

"Why Gloriosa Why!?" Sunset shouted in pain

"Sorry but it's the only way to keep Filthy Rich away from my camp." Gloriosa responded in a menacing tone

As she goes to the camp, Jason then saw her. He then hears the screams of Twilight and Sunset, and he used his machete to cut the vines to set them free. When he did he then pursued Gloriosa to the camp.

"He has freed us." Twilight said

"Yes but we must go back and warn the others!" Sunset replied as they travel back to the camp.

As they both entered the camp, Gloriosa enacts her intent to "protect" them by trapping the entire camp in a giant bramble cage. Little she did not know that she has seen the girls in front of her ready to make their stand.

But what came at them is Jason Voorhees himself. They screamed in terror, when he was ready to fight Gloriosa in a intense death battle. Gloriosa looked at his mask and she made a mask of her own colored rose and her goggles painted on it as she put on the mask. A battle between masked creatures has begun.
