Those who have quirks have come all corners of the world to become heroes and to train their quirks. Though on one day a soldier from another life who was taken and became one of the UNSC'S greatest soldiers a Spartan II super soldier with a AI who try to go home but now are stuck until another way was found. Still how will the pro heroes react when they see someone who was forge in the embers of war and fought against impossible odds. Still whatever these two groups will do isn't important to him. Only his duty as a Spartan to protect humanity no matter the cost.

They called him a traitor, He killed more then any. Command wanted him in chains, he broke them, He had trained for this since he could walk, now was the time to show who was the real alpha spartan. Some say he could challenge the chief, but saying it to his face would mean a challenge, he would not lose that challenge. No one escapes his sights, his enemies feel the bullets but none live to look at the carnage. His name? No one knows, his only identities are his spartan number 727 ,and his call sign...... Ghost

(Disclaimer: I don't own Halo 5 or RWBY.) What if Jaune was presumably killed during a mission after most of the student body, except teams RWBY and JNPR, turned on him after Cardin revealed his forged transcripts, only to be saved by the UNSC and made into a Spartan? (I'd also like to know if any of you guys could make some fan art for this series. I'd do it myself, but I'm not that good at art in general.)
