It had been months since the incisions. Most of the multiverse had perished in the collision of worlds, now only Earth 616 remained. A few heroes from the other worlds such as Miles Morales of the Ultimate Universe, and Gwen Stacy of Earth 65. Both being of the Spiders Army, they managed to escape their collapsing realities, before their demise. Joining the Avengers of Earth-616, the two continued their crime fighting carrier in their new reality.
Jessica Drew had gone on vacation to take care of her newborn child, leaving Gwen alone. Jessica had happily been a mentor for the young heroine, likely due to them sharing the same code name. Gwen wandered around Avenger’s Mansion. Over the past few days she had begun to feel a little strange. She could feel her powers growing, but not only her own natural abilities she had gained after having been bitten by that spider. No, she felt new abilities forming inside her. Feeling a bit nauseous, Gwen entered the bathroom, and turned on the faucet of the sink. She splashed some water on her face.
As she over looked the sink, Gwen began to sweat non-stop. He breathing became gasps, and her mind began to race, as she fell to the ground. Gwen's body burst into flames. She began to scream as the flames merged with her skin transforming her. A second pair of arms burst out from her pits, as all four of her arms became more amazon-like in form as they grew in muscle mass. Her legs gained some muscle mass, and her ass and breasts grew twice their size. She grew to 10-feet-tall, and long, curved horns burst out from her forehead, curving up. On all four of her hands, her nails grew, becoming 5-inch-long black claws as they sharpened themselves to a point. Her toenails followed and become talons. Large bat-like wings emerged from her back, as her skin turned blood red. Her eyes turned a fierce glowing yellow, and her teeth sharpened into fangs. A long, thin tail, with a spade-like tip emerged just above her newly enlarged ass. Finally, her hair turned into flames.
Gwen began to breathe deeply, gasping for air after her transformation was complete. She fell to her knees. Grabbing the sink with her upper left hand, her claws and enhanced strength caused her to crack it without even trying. She looked in the mirror, and to her shock she looked like a cross between herself and the demonic Surtur.
“Not the ideal host for my vast power, but I guess you’ll do!” a voice said in Gwen’s head.
“Who said that?” she though.
“I, Surtur.” The voice spoke again.
“GET OUT OF MY HEAD YOU MONSTER!” she said.
“Oh, I shall leave once you bond with my power.”
“What the fuck do you mean ‘bond with your power’?” Gwen asked furious, and still dizzy from her transformation.
“I have perished in the collision of universes, but my power lives on. Take it, become the new Surtur, and lay waster to all that is good and just!”
“Never!”
“Oh, but you must, I can feel your pussy getting wet at the though, no OUR cunt. My mind will no longer be a factor, but my power and essence will live on in your body, to do with as you see fit.”
“Ha! Then I’ll just use your powers for good! No villain will be able to stand up to my new might if that’s the case.” Gwen said smugly.
“If only it were that simple” the voice of Surtur chuckled. “None can remain pure with my power. For you see, it is evil itself. Sin, as a mortal may call it. Imagine what you could do to the world’s heroines. Seven powerful heralds, all loyal to you, and only you, ready to do as you command. Ready to fuck and corrupt at any moment you choose!” Surtur said.
She envisioned it. 7 beautiful heroines, all turned into sin demons, all loyal to her. Plus, while not turning them into sin demons, Miles Morals and Peter Parker would make for wonderful sex slave for her to have fun with. The last remains of Surtur’s mind vanished, engulphed into Gwen, as she left behind her old heroic ways, and set forth to begin her new life as The Deviless! Flames surrounded her as she put on a human façade, identical to her old look, and left the bathroom, ready to corrupt the universe.
