Zatanna's upgrade.

Arkham Asylum…

Sitting in their isolation cells in the dangerous wing of the mental hospital and prison, the super-criminals of Gotham city minded themselves to pass the time. With Poison Ivy tending to her plants and the Joker playing solitaire in his cell. All around them, dozens of armed guards kept a watchful eye on them all, pacing back and forth on rafters overhead looking down. They had all been trained for anything; from possible escapes from Bane to the Riddler, to the Joker.

So, the sudden flash of light and the arrival of a 12 feet tall satyress appearing in the center of the prison hall was quite a shock to all the guards.

Looking around with a smirk on her lips, Zatanna looked up at all the guards aiming their weapons down at her, screaming for her to put her hands over her head and get on the floor. Raising her hands over her head, Zatanna licked her lips. “seilfruttub onti nruT” Shocking everyone present, all the guard’s weapons burst into a flock of butterflies, fluttering around the bleak cell block.

Now that she had all their attention, Zatanna rested her hands at her wide hips and brayed out for everyone to focus on her. “Greetings dull, boring humans, my herd alpha, the great and virile Buck wishes to grant you all a gift, so that you may join him in feral rutted bliss.” Pausing in getting the security crew up to the high security cell block, the guards hesitated, listening in.

“And what’s this buck got to offer us?” Sneered two face, flipping a coin in his hand.

“Yes, never heard of him.” Purred Poison Ivy, crossing her arms under her bust and giving the satyress a better look. If Zatanna could be described in a single word it would have been huge! Easily over 12 feet tall and over half that around, she wore not a lick of clothes on her oversized and overweight frame, her entire body save for her belly, four breasts and face were covered in jet black fur, where a long tail with a tuft of fur wagged and swatted at her round ass cheeks and a pair of horns over her head curved and arched into the shape of a heart over her skull. The beast woman smiled.

“My Buck is the future of this world, through him we shall scour the blight of man and create a new Eden on Earth, one devoid of civilization!” Getting their attention, she continued. “Although my Buck would admire this city joining his fold, he ALSO admires variety, which is why I have come to you all, you shall ALL join the herd.”

“Oh? Hee hee hee, and how are you going to do that?” Chuckled the Joker, smearing his pale face against the bullet proof glass.

With a coy look over her shoulder, the bloated beast woman smiled almost as wide as the Joker’s. “I have been granted the power to gift others, before my arrival I have blessed the drinking water of this city with my mothers’ milk, even now the city brays out my lover’s name.

Meanwhile in Gotham…

Batman had his hands full, jumping from one roof top to the other, the Dark Knight was being chased by dozens of large female goat people, crying out for his attention. “Come BACK you handsome stud you.” “Yeah, we just wanna know if you’re cream filled!” Salacious and gluttonous beyond sanity, hundreds had turned in the span of an hour, and doubled that ten minutes later. If they weren’t colliding into each other to fornicate, they were stripping down and devouring the city one brick at a time. Even know every floor of the nearby buildings showed bloated goat people gnawing on stone and metal while orgies spontaneously formed on the streets.

“Come back here you handsome man-thing you.” Cooed a red furred satyress, wearing the ruined scraps of a batgirl costume as she and twelve others chased the Batman down. Eventually cornering him at the wall of another building. With his back to the wall, the Batman glared at the former batgirl, hefting her breasts in arousal as she sized her former ally up, then pounced.

“Ha, ha ha ha ha ha haaa a…” Rolling onto his back, kicking his legs out in laughter, the Joker fell into hysterics.

“So what, you think we’re gonna follow the word of some big, fat bruha?” Accused Bane, the rest of the inmates agreeing.

“Yes… I shall pass from this insanity.” Waved Mr Freeze, turning from his cell

Just then the guards finally managed to get the security door open and brought in reinforcements, armed and ready to fire at the Satyress. “EVERYONE ON HER!!!” Barked the chief guard, aiming a shotgun at the giant goat woman who looked on in amusement as they all surrounded her. “GET ON THE FLOOR OR WE WILL OPEN FIRE ON THE COUNT OF THREE!”

“One!”

“Two!”

“Three!”

“eriF” Whispered Zatanna, pointing towards the fire sprinklers over head. The moment the spark ignited; the entire asylum sprinkler system went off. The moment it did, the entire room fell to chaos. The guards dropped their guns as they were suddenly overcome with arousal. One guard struggled to undo his pants just as his cock swelled to over a foot in length and throbbed in girth to rival a beer can. Another pried her vest open, crying out as her breasts expanded larger. All around her Zatanna found the guards changing and growing, bursting out of their clothes as their cries of arousal turned to nickers of lust. But as amusing as that was, her attention fell to the Rogue’s Gallery before her.

The still laughing Joker, continued to laugh on his back, his shoes bursting off his cloven feet and the front of his pants ripped open to free his turgid erection, a sheen of bright green fur spreading down his body as he grew. Poison Ivy moaned out loud as red fur crept down her body, her figure swelling larger and more curvaceous before a second pair of breasts grew under her original pair. Two-Face cried out and gasped, struggling to hold down his growing erection as his face rapidly healed, then out of discomfort when a single horn grew out of his forehead and a second HEAD grew from his left shoulder!

“Yes, YES, join us, join the herd!”

Harley Quinn laughed out loud as albino fur covered her body, what scraps of cloths she still had on were torn off to free her now four heavy breasts and transformed body, nickering as she lifted her tail, flagging her arousal. With the sprinklers still going the group of villains and guard collided with each other, overwhelmed with desire. One of the guards thrust into the other as his horns grew out of his scalp, his stomach turning into a paunch and his balls swelling to the size of oranges. “Hnnngh… Take it! TAKE IT!”

“Yes, MORE! Give me MOAR!” The female guard cried out in orgasm as her own horns sprouted from her head, nickering as the one mounting her from behind reared back and fired off a torrent of seed inside of her. All around her Zatanna watched on as the asylum turned into an orgy. Even now half the city must have joined Buck’s herd and were intent to feed and breed in his name. Looking down at the puddle of water at her cloven feet, where a rim of moss and grass bloomed at its edges, Zatanna frowned back at her human face. Pressing her hands against her cheeks and pinching her nose, the satyress groaned. Looking down at the rest of herself, she felt she was magnificent; she stood twice the height and ten times the weight of a normal human, she could eat anything and bear multiple litters of kids in the span of hours. Her body was covered in a sheen of thick black fur that would keep her protected in the weather, but even then she looked like a woman in a goat costume who was so fat she couldn’t get the zipper over her belly and left her face and tits flopping out, forgetting her mask altogether.

Yes, she was one of Buck’s prized heifers, but it still wasn’t enough for Zatanna. She wanted to prove she was worthy of Buck’s herd. She had abandoned her loyalties, her figure, her taboos, everything to Buck… Except her humanity. Closing her eyes, she looked deep within herself, looking over the tapestry of her entire life leading up to now. Her childhood, her adventures with the Justice League, everything that made her who she was. Without hesitation she grabbed a chunk of that tapestry and ripped it out, shoving it into her mouth and swallowing hard. Ravenously she devoured her memories, her identity, her everything bite by bite. By the time she was done barely crumbs remained of who she was.

When she opened her eyes, the she-beast looked down to look at her reflection. Fur now covered her entire body, leaving only her leathery areolas and stiff nipples exposed to drip mother’s milk on the ground. Her brow, nose and upper lip had merged and was now all covered in fur, and her irises had become square like a goat’s. “I’ve done it!” She meant to say, but all that came out was a nicker, she had even devoured her capacity to speak. But now her humanity was gone, she was pure satyr! She was… Was… Closing her eyes again, she tried to find something, anything to draw on, finding nothing, save for a single letter floating in her mind, ‘Z’.

‘I am Zee, Zee the matriarch, broodmare to Buck’s herd…’ She thought out loud, but to her surprise when she declared that in her head, the entire crowd of satyrs in the asylum bleated out in triumph. Making the pure satyress smile. ‘You will go forth and breed, multiply, expand our numbers until this city is Gone! Then devour it! Leave nothing but the soil for plants to take root.’ She thought as loud as she could.

“YES! Spread the green! Devour Gotham!” Moaned Ivy while two bulls speared into her from front and behind.

“Create.” “And Destroy!” “Create.” “And destroy!” Bleated the two heads of Two face, spearing into a female guard he pinned to the wall.

She figured it out. Zee had become more connected to the herd then ever before! They were a part of her just as much as she was a part of Buck now. Storming her way out of the asylum, Zee looked over the cliff side overlooking Gotham city where even from her location she could see it crumbling under the weight of her herd picking it clean like maggots on flesh. ‘FOR BUCK!’ She broadcasted from her mind, shivering in arousal when she heard the chorus of thousands of voices in the city repeat her.

“FOR BUCK!!!!”
