So, I've totally been besotted with FuriarossaAndMimma (https://www.deviantart.com/furiarossaandmimma) depiction of gabrielsangel (https://www.deviantart.com/gabrielsangel) 's my little mermaid hannibal AU, and I've always been a fan of merman!Will ♡♥♡♥♡
So where I'm going with this is that I've just had this thought....
Merman!Hannibal poisons Fisherman!Will and he slowly turns into merman (and freaks out because of that, in his Will way)(and this is the "quick" way to repopulate the mer-people community)
Sooooo..... yeah ~Puppyyayplz (https://www.deviantart.com/puppyyayplz) Totally drawing that!!! ^_^ This shall be my head cannon merman AU ^_^
Or we can always go down a far darker route :mwahaha: ........
