So, can Marinette also make physical illusions? (Also, I love that Paradise went from a simple genderbend au to probably your darkest au)
Yes. Simply put, illusions are extremely versatile. so allow me. Also, time to fine tune this bitch in here.
We start with this Volpina.
Volpina in Miraculous AU is terrifying as she realizes the true power of illusions. She can create invisible illusions to patrol the city and stalk the other heroes, camouflage herself with the environment so only a truly perceptive eye can see her, create illusionary nine tailed foxes as combative guards that are real until harmed when they vanish, mimic other voices, false environments, and just so much more.
In a certain chapter I'm fine tuning, you see just how easily she can manipulate things with illusions. She watches the situations from afar through her illusions, sharing "false" memories to the other heroes, eavesdrop, and possibly more. In a scene with Viperion, she's able to showcase her using the voice mimic and makes Viperion de-transform and transform again before helping the unconscious heroes de-transform.
In a few deleted chapters, she is seen conversing with Sleuthlynx through her illusionary foxes. Her thoughts projected and spoken by the illusion.
This is all due to her lesser power being that of illusions and her greater power (that she doesn't use as often) is shapeshifting.
Transformation: "Trixx, Conceal"
And that brings me to Volpina from Absolution. This Volpina can do the mentioned above, but is never on the field. She always sends illusionary doppelgangers to do her work while she remains in a safe, hidden location. I don't have as much on her compared to her Miraculous AU counterpart, though Absolution is going through a massive overhaul in terms of story, so yeah.
Speaking of the overhaul, shapeshifting was dropped to keep the illusions power. Her passive is a form of persuasion where whatever she says, people believe (much like Hoaxer) with her main power being Illusions.
Transformation: "Trixx, Conceal"
Now, Vixen for Separate Worlds won't be as crazy with her illusionary powers, but did use them to enhance her performances. Creating a spectral and ethereal display/concert to accompany here. This would range from illusionary back up singers, music as she'd deviate and do her own thing, to a play that fills the room that'd usually be akin to a movie with the moving illusions putting on a play.
Her illusions are a mix of false and real. Meaning if one were to interact with them. They'd either feel as real as another person or their hands would pass through the illusion as it dissipated like it never existed.
Transformation: "Trixx, Conceal"
I've got plans for this anxious child. I'm putting them here because it's set in stone, but I'll add powers once the plan is in action
A slight change of plans with Paradise. Bridgette will be the fox holder known as Void. Given what I've set up for Paradise, Void will be a mirror to Miraculous AU's Volpina. She can create a network of shadowy illusions and see through them all, create illusions capable of harm, but can't take any damage otherwise they are destroyed, speak through her illusions, and more. The only limit really is her imagination.
Transformation: "Trixx, shroud."
Alya is finally Rena in Amaranthine. Her power is that of illusions on par with that of Miraculous AU!Volpina.
Transformation: "Trixx, shroud."
Lila returns once again with the fox as the fox heir in Court of Miracles. She is Midborn and her powers include:
Lila takes her place as Volpina once again in All That Remained. Her power, like many times before, are illusions.
Transformation: "Trixx, shroud."
