Who notices Venomina's profile refers to her as a werespider instead of an arachne? You know if that's what she's called then beast girls such as bat breeders & a possible female minotaur should be called werebats & werecattle/werecow respectively
I think we are most likely talking about our 'opinions' here but I'm under the impression that usually when a word is preceded by "were" it implies that some form '
transformation' is happening or has happened.
Werewolves do transform between wolf and human form. Venomina does have a spider form and can apparently transform back to it or do it partially.
Bat breeders however don't seem like that. We always see them in their current hybrid form. No transformation has happened to our knowledge based on the game.
But then again, these are not solid rules nor do the etymology of the word 'were+word' implies transformation.
