Batman vs. The Changelings
By: WhatTheFap

Canterlot was in chaos. It was the season 2 finale wedding shit and Chrysalis' Changeling army was attacking the innocent equines. Ponies were beaten up, ponies were robbed, and some ponies were raped by the vicious Changelings.

Batman returned to (what he thought was) Gotham City in order to stop Bane from blowing it up or something, but instead found a colorful, yet violent, world of horses being raped by evil-looking creatures. Lyra looked over at Batman with worry in her eyes as she was being quintuple penetrated by Changelin weiners.
"Batman!" She yelled. "Do something!"
"EHEEHEHEHEHEHEHE! OKAY!" Batman yelled back.

With a mighty, forceful tear, Batman ripped off the penis-compressing tights he had been wear to reveal his BatCock. The BatCock was no ordinary cock. Equipped with two sets of ballistic missile attachments, and a main cannon as the urethra, this cock could penetrate like no other cock before it.

Batman carefully took aim and fired 5 shots at the gangbang that Lyra was enduring, and hit each one square in the jaw with the cock shell penis cannon 420 marijuana bullets. Lyra thanked him for basically saving her life, and Batman responded by saying: "FOR A GOOD LAUGH, DOWNLOAD THE INDIE GAME COMEDY NIGHT. JUST SEARCH IT ON BING! WELL WORTH IT!", which made Lyra extremely wet and start hoofing herself until she died of AIDS.

Batman sprinted unnecessarily to the center of Canterlot, where he saw the mane five (Fuck Rarity, let's just say she died or something) doing a semi-notreally badass fight scene. Pinkie was fisting Twilight's ass to make her fire laser cum out of her horn, which worked pretty well at first, but eventually fizzled out when Twilight realized that she was into anal fisting. Pinkie looked over and saw Batman.
"Oki Doki Loki!" She said. (LOL THOR REFERENCE AMIFUNNY GUISE?) "You'll have to do!"
Pinkie knew the secret to destroying the Changelings with Batman. She had to fuck him until he fired his cannon load into her cunt and stomach and face and dick. Once that was done, Pinkie would eat out her own pussy until she came his cannon jizz load back out. When that happened, it would created an EDP (Erection Destroying Pulse) that would make the Changelings' dicks exploded, and therefore make them unable to rape anyone, thus saving Canterlot.

Pinkie turned around and shoved her cunt onto Batman's dick with a massive force. Batman got flustered and prematurely cannon fired since he was a virgin. Pinkie wasn't ready, since she thought he would do better than THAT, and the cannon shell thing went straight through her, killing her instantly.

The cannon shell jizz shit, still intact, lodged itself in Twilight Sparkle's cunt for a change. Twilight had trained for this moment for millenia, and now was her final moment to shine.
"KA ME..... HA ME.... fusroDAAAAAAAHHHHHHH!!!!!!" She yelled while glowing furiously and shooting shockwaves of the EDP out of her cunt.

All over Canterlot, the Changelings thought they'd won. But, in the midst of their victory prep, their dicks exploded! Knowing how helpless and weak they were now, they left Canterlot and killed themselves with mayonnaise and snorkels. Don't ask me how.

Like any season finale ever, all the mane FIVE ponies were treated like heros, along with the B-ster. Princess Celestia gave a shitty speech, and asserted her dominance over the lessers. All the ponies shared a big laugh, had a big orgy in Canterlot, and then everypony forget who the mane 5 were in a matter of hours.
Batman went back to Gotham and failed at saving everyone, so he quit crime fighting and became an accountant.

To be continued.
