Perhaps an obvious "give-away" sign of the mc'd superheroine (or subjugated civilian, prison wardress and policewoman) is the pose where their hands rest, fingers straight down, alongside their thighs - in effect, "at attention"; you've captured this well with the "re-wired" Erica in CotG2 and also, looking back, some of the scenes of the subjugated Mayor after she has been "greentoothed".
Another sign of a re-ordered brain might be a more upright stance- such as the moment when Erica, power-locked inside the Psych-slaver, realises that she is REALLY in trouble when the Warden snaps to attention. Perhaps the mc'd victim should always be fitted with stiletto-heeled boots to alter their stance?
You don't need the re-wired victims to be naked - the subtle changes in their stance would be a great give-away that "her mind is no longer her own". Especially when she walks in, dressed in her civilian clothes, carrying a
Greentooth "Pacifier" concealed in her hand ready to capture her target female for subjugation.
I'm tempted to suggest that you design a smaller head-set for Erica and other subjugated superheroines, lodged (or perhaps locked - give us a close-up of the earpiece latching around the back of her ear as she is enslaved) in one ear, with a thin microphone wand extending along her jaw-line (to end in a sinister green glowing LED). These would look more normal; I suspect that Ms Giolla's first headset for her enslaved cop looks like a set of Bugs Bunny ears and would not blend in when Erica goes out to capture more "recruits" for Ms Giolla's domination process.
Superb artwork, inspiring stories - please keep up the good work.
