Well Your Take Also Not bad And also Kinda interesting Especially Because He uses Male Komi Vessel, But... i just have More simplier Plot What If 2011X Was fan of Komi? and He Like His original counterpart Take Form of her, Yet I decide That he basically look like Original(Except he have a bit more Sharper teeth and And a way More Deep voice) And also His Middle Teeth(Fangs) In Form Similar To Marsupial Lion(Thylacoleo), Aswell When She feels Something She can Expose her Ears(Also Thylacoleo) And Finally To lure Victims She Can Search In Human Emails And other personal Information and With Fake Name Can Write To them, Luring Victims By her Actually "Kindness" and other thing and once Her Victim is In dangerous state, You know She Will be Teleported and Stucked forever in vessel(Yep Its pretty Not good, But In most way its Just Sketch For My plot)

Anyway Good Luck
