Its finished finally got these ideas. I really like how it came out. This particular interaction got my noggin jogging as it has all of my symbolism connected.
I really like the idea of Vox being this predatory cult leader who's manipulated thousands of children for his own selfish ego. And that with this experience passed on to his "new life" finding out Charlie is a "child" that stays like that FOREVER. His depravity is heightened, his controlling nature, and revolting fascination is consuming him. To him Charlie is what hes always wanted; she is an OBJECT something he can manipulate like a puppet, she is only good for what she offers her body. (Allegory for his victims and CSA in general)
My idea was that he wants her for her body and or power. He would hypnotize her, shaming her and making her feel bad that she's a FAILURE as a Princess and that without her doing anything sooner thousands of her people were suffering/died.
While she is distracted he plugs his AUX cords in her neck, using her as a battery essentially gaining all of her hellish powers. Finally getting a body (hers now "merged" with his body.)
He becomes enormous, faster, godly even. He is no longer tethered to electricity. His "unrecognizable" human form is now given flesh able to leave his screen (only partially) he can now conjure things in his screen to attack. Charlie's body is now lifeless, being puppeted by Vox as an extension of himself. Her body is exposed showing her doll anatomy, as her purpose now is to serve him. He uses Charlie to fight for him, summoning hellish weapons her family have. The gang would not be able to fight him as they could hurt or kill her, she is his shield and his weapon. Alastor would be the only one that would fight him as their deal was to protect her (plus he wants her power and seeing a demon that ISN'T him steal it from him pisses him off.)
She would be freed and Vox is now weaker, as a princess Charlie has released ALL of his contracts. Vox for the first time feels fear, he is absolutely frightened begging for Charlie to forgive him, that he can change he promises. Charlie now growing realizing that not all demons can be saved catharticly uses her powers to imprison Vox. He is reduced to electricity an object for the people to use, much like how he used his victims. And for the rest of his eternal punishment he is ripped apart, used up, and lonely with nothing else to control. He gets driven mad and fragments till the end of time.
As Always
