Silly thought
Vox but with hair
Here he was horribly disfigured (and probably some facial parts were dysfunctional) so he replaced everything with tech (especially his face with a led screen)

Backstory: After brainstorming, my friend n I hv a guess that Alastor's contract is he becomes (or be controlled through) a voodoo doll. He is constantly watched and controlled by someone (to me, maybe a female figure). So he craves for his freedom.
Or... he sews his own mouth and keeps a permanent smile to not let the person that watches at him knows his thoughts. He needs to protect himself by his smile, this shows his insecurity deep down in his heart. The lost of control over his own life drives him crazy...
After the doodle, the thought of he sews his own mouth out of his insecurity makes him more pitiful so I prefer that now
(Yes I love to see him suffer)
