An alt timeline where Jaune after leaving Beacon went home however still somehow became a Campione The eighth King: The white Dragon Emperor

What if Jaune was a clone of the 501st but then found himself on a different planet during the battle of Umbara. Will he rejoin his brothers or find a new purpose on Remnant?

All he wanted was to be a hero a shining knight like his ancestors before him. Now that's impossible no team, no family, no friends, no future. All he has now is to wait for the darkness to consume him, but from that darkness a new knight shall rise!!! RIP Kevin Conroy/Batman

Jaune save Cardin Life by killing the Ursa Major along with a few ancient Grimm.(This AU he has some skills ). He believes that Cardin will be grateful for saving his life will stop blackmailing him. However, Cardin decided to spill his secret after Forever falls which caused the whole first year and some of the second year student to abuse him. It caused him to lose what was important to him. After being abandoned by both his parent and his own team. Jaune disappears to return couple months changed looking little 2 years older and more powerful and with his lovers. He is ready to save remnant with his semblance magic and quirks to defeat the evil in his world. Will he be able to defend his old home until the world collides into one. Or will the darkness take over remnant before it collides Cover made by @DarkRose--Chan (ancient grimm are like myth dragon, phoenix, Manticore and Sea serpent)

What if Jaune didn't have to fake his way into Beacon? What if he wasn't just the lovable dork....but also a cold and merciless warrior, a clam and wise leader and a strong and durable man. What if he didn't lie his way in....because he had no reason to.

Instead of Sephiroth, Jaune took his place after he was betrayed by her friends except Ruby, Blake, Nora, Ren, teams CFVY and the staff. But still that didn't stop him from being expelled and disowned. Given and opportunity on a different Land where a company exists Jaune went through some experiments without memory and soon became a hero. A soldier first class Jaune.

Not even going to bother with a summary. If you're even reading this you already know what happens. The difference is this one has better grammar.
