Since Hera is traveling along with everyone, is she a huntsman trained dog? does she have her aura unlocked?
Hera isn’t necessarily “trained” to be a Huntsman dog. She does start to train with her Papa, uncle Ren and aunties Nora and Ruby when they’re traveling together, but before that she was just Jaune and Pyrrha’s little girl. The first fight Hera actually really participates in is the Battle at Haven, when she rips off Lionheart’s tail and then headbutts Cinder off of her Papa.
As for the Aura part, yes she does! Jaune unlocked it for her after the Fall of Beacon mostly to just help keep her safe on the journey, even though at that time he didn’t know how much butt she’d be able to kick (or bite) in the future! She even gets her own semblance! “Mega Bark”!
