Have you ever thought about an au where Jaune is a wolf faunus and Ruby is a dog faunus?
When I look back, Jaune may have the appearance of a dog, but acts more like a wolf. I mean, he's the only one in the group who goes for a kill blow when an enemy is down.
Ruby has the appearance of a wolf, but she acts more like a dog. Being a silver eyed warrior, she is meant to preserve life. The worst she's done to a person was cut off Tyrian's tail.
If you did make this AU, I can see the relationship being that Ruby playfully dominates Jaune.
The Pupper and Woofy.
Wolf Jaune: I'm on a hunt. I'm hunter, a proud warrior like my father and his before me and I have my prey on sight...
Sheep Cruz: Baaaa..... (Oh no. 💕I hope no handsome blonde wolf attack and ravish me from behind. That would be so bad if it happens. *giggle*😋)
Jaune: Target located, ready to pounce and... Strike.
Cruz: Oh No!!! I'm about to be eaten by the big bad dic..... I mean wolf! Whatever should I do? 🤤
Dog Ruby: Have no fear for I am here! Get to safety you dumb sheep I will gladly put myself in harm's way to safe you! Go ahead wolf. Eat me but please leave the dirty sheep alone!
Cruz: Tsch! (Get a clue you dumb bitch!)
Jaune: Ehh.... What is happening?
Ruby: You heard me. Eat me. Ravish me, devour me (sexually) with your mouth... (Then your dick afterward.)
Jaune: I think I better go...
Ruby: Oh no you don't! Get back here and finish me! Mama wanted her climax!!!
Jaune: *runs away*
Cruz: No!!!!
Ruby: My Wolf D!!!!
