..Since that one doesn't sound like a person that would be evil — though she looks more like a Princess from one of Disney's fairy-tale base movie to the plant creature she was turned into in the canon timeline.
- Jossed. Rose ends up becoming an OC Battle Couple with Juleka.
In-canon, Volpina was created by Hawk Moth as an Evil Knockoff of the typical wielder of the Fox Miraculous, with Alya becoming the official wielder of the Fox Miraculous Rena Rouge.
In the fanfic's canon however, the box that houses the Guardian's entire miraculous collection was stolen by the main antagonist, ready to be corrupted for a later time like the Cat Miraculous. This presents the idea that Alya will be chosen a second time by Lady Nymph to fight the good fight when Volpina (chosen to be Lila for her lying, ambitious nature) surfaces to be an accomplice to Catastrophe and become an tianshi-based copy named Rena Rouge.
- Half-confirmed. While no appearance of Rena Rouge yet, Lila is currently working with Catastrophe and the Big Bad as Volpina using the Fox miraculous, having been picked as to not waste energy to corrupt another miraculous.
May or may not be tied to getting the Peacock Miraculous.
- The part about him becoming a her Secret Keeper is confirmed in Chapter 29.
He's already in the know.
- Jossed. It's Chloé.
While the Butterfly Miraculous fell into the hands of an unknown person in this continuity, it is pretty clear that Gabriel is still involved, him being able to remain composed when staring down his supervillain son and possessing the miraculous book. The Peacock is still missing, so it can be presumed that he happened upon it like in-canon, this being the reason why his wife is still "missing". Recognizing how dangerous the miraculous is, he has been holding off using it when Catastrophe and Nymph's Champions started appearing, but the reality that his son is so deeply involved in it
Odds are his motivations will remain the same at they are in-canon - get the Ladybug and Black Cat Miraculous to revive his wife - but he won't have the Butterfly Miraculous to create the stupefyingly powerful foes as he did in-canon. Not only that, but he won't be nearly as active due to the damaged condition of the Peacock Miraculous, going several chapters without appearing, and will be forced to find alternatives in gaining the miraculous. Odds are he will introduce himself by amokizing one of Nymph's champions and speaking directly to Nymph through them, introducing his motives and gives her a "with me or against me" speech to her, flip-floping in using his sentimonsters to help the heroes or the villains depending on the situation.
What you want to bet the first person he uses to create a sentimonster is Audrey Bourgious, harnessing her rage at Chloe ditching the fashion show?
- Jossed. Nathaniel happens upon the Peacock Miraculous and Alya becomes a hero with it.
It could either be an ongoing problem, or he could have mood-swings, switching between his canon-counterpart's lovable personality and moments where he acts less scrupulous than necessary whenever a Berserk Button is pushed.
- Jossed. He's just The Atoner.
