Ooh goodness yes, there’s so many routes this could go. Whether his target is an ABDL or not, or even himself.

If his target were into such things and he wasn’t, he’d surely adjust. Forcing himself to enjoy what they did, eventually having fantasies to fulfill his victim’s.

If he were into being his victim’s CG, whether or not they’re into such things, he’d lovingly create a whole nursery just perfect for them. Every single little detail being fine tuned to their needs and wants, their interests and being able to keep his beloved in this sacred space.

Surely he’d be less violent than usual Yandere Medic tropes, but more forceful. Using cutesy restraints to keep them around, babying his beloved and making their mind vulnerable to his affections. His obsession is kind, loving. It’d be impossible to think of the deranged thoughts in his mind, cooing to softly to the object of his desire.

You could even go the other route, Medic being an ABDL and wanting his obsession to care for him. Dreaming of being coddled and cared for by his victim, wishing he could snap his fingers and hypnotize them into being his CG. The possibilities are endless in terms of merging those tropes!!
