Here's one story from Hardrocker21. The Freddy Krueger one...
He mentioned Ganger, which is a villain from THE STORY OF DITTO.
Which might make this interesting. Techinally Ganger was a "Karma-Houdini", he was never punished for his actions, he basically got away basically scott-free.. So this story will probably be satifying..
But first.. A summary for those who need it..
The story of Ditto actually consists of 2 stories..
In story 1, Ganger seems less evil, and the readers can somewhat sympathise with him, due to being turned into an Changeling against his will. But he still has fairly villainous scenes. Most notably, is when he nearly turns Rainbow Dash into a changeling, and calls her a bitch.
But in Story 2, Ganger is far less sympathised by the readers. Leaving it questionable if he "ever was".
He wants revenge on the now redeemed Ditto for kidnapping and turning him into a changeling. But his plans for doing so involve kidnapping little Scootaloo, after finding out that the little filly is one of the few things Ditto ever truly cared about anymore.
Ganger discovers Scootaloo's location, while the filly is hanging with Rainbow Dash. And when Rainbow discovers Ganger's intentions of taking her beloved sister figure, Dash falls into "papa wolf mode" and defends Scootaloo by giving one of the stories largest fight scenes. But in the end Ganger DOSE get Scootaloo, but only because he doesn't play 100% fairly.
Later, Ganger reveals the captured Scootaloo towards Ditto, as a tempt to get Ditto to give himself up. However Celestia, who was there as well, remembers Ganger as one of her loyal guards that went M.I.A, and tries to reason with him. But Ganger ignores her, angering Celestia into a firing spell at him, but it hits one of his minions instead, despite being a non fatal spell it ends up being the reason for the minions death, due to it causing an chain reaction of injuring towards the minion.
Angered by the death, Ganger begins an attack on Ditto and the princess, and after an intense battle. Ganger nearrly klling Ditto. And one of Ganger's minions accidantally drops Scootaloo (who can't fly).
Ganger is outnumbered when all the guards come to defend Celestia, and he has to leave. His fate unknown.
Until now (Mwahahaha).
So after kidnapping Scootaloo, trying to kill Ditto and Celestiam and causing mass panic most likely.
Ganger, still a changeling, ends up working as a janitor at Scootaloo's school ironically enough. But during a cold day, someone touches the heater against Ganger's warning. And Ganger is horribly and brutally burnt, but all the fire extrinster and water are dry. So he runs to a school meeting screaming for help, but is simply ignored as the meeting continues. Ganger simply just finds a seat and waits til after.
But a few seconds into it, Ganger is horribly killed by the flames still covering him. And he swears revenge against all the kids (who were innocent of this), by entering their dreams, and finally dies. Even cleaning up his own ashes somehow.
When Scootaloo is asleep Ganger does indeed appear in her dream. Fully commiting to the Freddy Krueger plot, and dressing up like him. He makes a pun and than a dramatic laugh before swings a rake at her, making her wake up screaming, and finding an actual scar left on her body where he dream scratched her.
Everyone at school admits having dreams of Ganger. And at class Silver Spoon finishes a test early and falls asleep. But what starts as a normal dream ends with Freddy/Ganger appears, and strangeling her with a supernatural tongue. Spoon suffers the effects in real life and dies in class (honestly, Martin dream choking always kinda disturbed me, not even sure if it was meant as a joke).
Eventually the crusaders realize what's happening and try to stay awake to avoid dreaming, but eventually decide to go to sleep and dream fight Ganger.
Scootaloo falls asleep as the other two promise to watch from the real world. But as Scoot and Ganger fight, turns out they also fell asleep. But Ganger falls into quicksand. Only to reappear later as a giant spider. But than an accorn falls off a tree and clogs Ganger's spider form, causing Ganger to explode.
The next day, everything is back to normal, but AppleBloom is still worried that Ganger still might be out in the world somewhere, waiting to kill them in ways they can't imagine.
A bus then stops in front of them, allowing the normalized Ganger to get off where he makes a few pathetic attempts to scare the children with scary faces, before the bus takes off, Gangee chases after it (forgetting he could fly) because he left his gun on one of the seats. But while chasing the bus, another one crashes into him. Flattening him like a pancake.
