have Vulture and Hyena interacted with your other Horror skeletons, and if so how did that go/ what do they think of them?
Out of curiosity they have. And they consider themselves the lucky ones thanks to it.
Condor and Anubis were considered for recruitment, but both have this strange but strong moral compass that prevented them from agreeing. They both feel that someday they can fix things still, and refuse to cause unnecessary harm.
Cuckoo is just fucking BONKERS. He tries to bite, kill, and/or eat every living soul in sight, or tries to feed it to Maned. Being smaller and faster, Cuckoo has nearly toppled both Vulture and Hyena and neither want to talk about that fight.
Grim and Raven avoid others far too much. And Grim attacks anyone who tries to get near Raven, both as warning and to protect his brother. Raven... doesn't listen well. And is very bitey if he smells something new and alive close to him.
Ringo is... something else they don't want to get near.
So while some would be great candidates to work for Nightmare, he's simply had his mark left in those AUs to feed off them.
Vulture and Hyena would prefer to just continue annoying their Classic Past Selves.
