Some years ago...I made a god awful Phantom of the Opera Fanfiction just with my Humanimal Characters in place of the canon ones...I feel I owe it to society an apology story for that travesty and with my much more concrete view of Humanimal Society, what Humanimals can and can not do my mind started cooking up a plot similar to but not exactly the same as Terry Pratchett's Discworld Book Maskerade At first the one building an Opera House in the Eden Lands was Oswald 'Penguin' Cobblepot but then I remembered something important from Mutation of Nubs, at the end of that story Penguin got in trouble with the entire Earth Government for trafficking Humanimals to the enemy Princes...For fricking treason Penguin isn't going to Arkham or Stonegate...He's headed for Space Prison, presumably somewhere on Earth's moon
But then a different idea came to me the Splicers of Batman Beyond...If Splicers came into being in a world where Uplifted Humanimals had already existed for thousands of years what would happen?
And I thought if Splicers were attempting to BE Humanimals in this version...And Humanimals simply walk away thinking 'Posers' if they're polite or flat out call them posers if they're not
I started imaging Abel Cuvier" building of an Opera House in the Eden Lands is something he claims is an act of goodwill to the Humanimals...But one of the Humanimal denizens of the Eden Lands suspect the Splicers are attempting to steal Humanimal Kind's secrets of the teenage Humanimal becomes a Phantom and starts attacking the ordinary Human Workers of the Opera House (Never seems to catch any of the Splicers) and it's up to the Humanimals and the Turtles to stop him...Thing is...The Phantom wasn't wrong
So...Splicers were a thing, they had been a thing in Gotham City for a half a year. A lot of Humans in Gotham City didn't approve and the GCPD was seeking to make splicing illegal.
That was probably what prompted Abel Cuvier and his henchman to move to the UK specifically the Eden Lands the uncontested Kingdom of the Unicorn Monarchy where Humanimals lived free from human interference.
As a show of goodwill Cuvier constructed a great Opera House near the Southern Border of the Eden Lands "Perhaps you Humanimals can demonstrate some of your traditional songs for us." Cuvier said at the groundbreaking.
As all this was happening, Matoaka didn't think much one way of the other, to her the Splicers were posers no more no less, their attempts to become like Animals were obnoxious to her...And the GCPD and Batman were right when they said it caused the Splicers to become extremely aggressive...If you're not born an Animal you have no idea how to properly act like one...Matoaka figured that after the Splicers had hurt themselves and/or other people enough they'd all be clamoring for a reversal in a few months.
However during the month of October, two weeks before Halloween. Matoaka got a call...Someone...Believed to be a Humanimal of the Eden Lands was attacking the innocent Human Workers of the opera house and vandalizing it.
Matoaka brought her crew, Jonathan Crane and Edward Nygma (As they were from Gotham City they might have...Something…) And Donatello who was currently the only Ninja Turtle available all his brothers were hibernating on Third Earth where Winter was putting NYC in a Polar Vortex, Don was on a sabbatical with his Dragon Wife Belladonna.
When reaching the opera house they were showed the footage from the security cameras.
The footage was strange and uncanny, a tall creature, dressed entirly in scent proof latex 'Clever Beast' Matoaka thought sourly and to further hide himself he also had a latex cape with a very large collar so no one could discern what species he might be.
But Edward Green, once a Humanimal Hunter of the Greatest Magnitude examined every video that the creature was caught on then he said "Wolf." Our suspect is a Wolf."
His Dad, the infamous Edward 'Riddler' Nygma groaned "How on earth can you tell he's a Wolf?!"
Edward Green simply pointed to a screen with a video of the suspect running, his long cape trailing behind him. "The legs." Edward Green said "Those are the distinctly crooked legs of a Canine, there is even a bit of the underside of the tail, a medium tail unlike the elaborate brush of the Vulpine Family."
Edward Nygma blushed feeling stupid at having not been able to realize that.
"He is a rather large specimen of his species." Edward Green said stroking his chin "Normally Wolf Humanimals of either sex don't exceed five feet but this one is six feet...Potential candidate for the FBA "(Furry Basketball Association all Humanimal league) "And that's what worries me."
Turning to the video where the Wolf attacked a stagehand, Donatello winced as the Wolf ran toward the defenseless human and beat him savagely with a long stick, it wasn't a Bo Staff, or any kind of actually staff just seemed to be a stick as long the wolf's long forearm...When the Man screamed and other Workers came running the Wolf quickly fled...The Wolf clearly wasn't a skilled fighter but he made up for that with sheer strength and deadly energy.
"That Wolf is my brother." Came a soft and musical voice.
Everyone turned around to see a Svelte She-Wolf Humanimal standing in the doorway.
"My name is Gray Claw." Said the Pretty She-Wolf "That is my brother White Fang."
No beating around the bush the thing here is not figuring out who the Phantom is but how they can apprehend him without killing him.
