Jaune's Semblance will involve Adam.
- Instead of his reinforcement Semblance, Jaune will have the ability to have Adam possess him. The Semblance will evolve as Jaune and Adam bond until its ultimate form, where Jaune and Adam gain the ability to fuse into one being.
- Alternatively, his Semblance will allow him to summon Adam, like the Stands from Jojos Bizarre Adventure.
Sienna Kahn will become the Big Bad.
- Sienna Kahn may not be the worst person on Remnant, but she's still a violent terrorist with a vendetta against humanity. Even if Jaune does become genuinely invested in fighting injustice, he maybe forced to deal with the fact that his employer is still a dangerous person. The breaking point will be when Sienna directly orders Jaune to do something truly heinous.
Jaune might be forced to fight Sienna directly, and this might end with him becoming leader of the Fang.
Jaune might hit a low point in his life, but his family will be the ones to pull him out of it.
At one point, Jaune may not only see his reputation tarnished, but he'll lose everything he's gained: his followers, his minions, his connection to Lisa Lavender. But his family, the only people on Remnant who know Jaune isn't a monster, have probably been following his exploits. And while they'll tell him off for being so reckless, they'll also pat him on the back for the good he's done.
Cinder might try and sabotage Jaune
.Aside from the fact that Jaune has no interest in destroying Beacon, Cinder would hate Jaune for actually bringing hope to people. Salem opposes anything that could unite humanity and faunus against her, and Cinder's plan relies on mercilessly shredding the hope of others for power. So what better way to get what she wants than make Jaune look like a monster in front of others.
