X

X is a mask-wearing student from another kingdom that attended Beacon Academy weeks after the initiation.

Background
He was immediately transferred from another school for just being too dangerous. He made the suggestion to be transferred to Beacon.

No one knows anything about him. He is always concealed in a full-body suit and a mask. He quickly became the most advanced student in the whole school. The other students then noticed he's taken a interest to Jaune Arc. He is always challenging Jaune to a duel. Every time Jaune lost, X would demand a rematch, and would talk back to anyone who tells him otherwise. He is obsessed with fight Jaune, and has been getting more enraged every time.

He was later revealed to be a Dragon Faunus. During The War, his great-great-grandfather was the most fierce and dangerous of all Faunus. He was then defeated by Jaune's great-great-grandfather. Slain by the same sword Jaune holds. That day has haunted X's family for generations. He has held a grudge against the Arc Family all his life. His suggestion to be transferred to Beacon was to face the most recent member, Jaune. But Jaune's failures have frustrated him, for defeating a disgrace to his own family is not how he envisioned to take his revenge. X wants him to improve on his skills so he can truly defeat the Arc Family the "right way".

Abilities & Powers
His skills in combat, and uses for his Aura are almost unlimited. His hatred for the Arcs has motivated him to be the mightiest weapon to avenge his ancestor.

Being part dragon, X can breath fire from his mouth, which he can do with his mask off. His strength is not to be questioned.

His primary weapon is black blade sword with a cross hilt, which looks a lot like an "X". He can grab the sword's guard and split the sword in half. The two halves can act as tonfas. His secondary weapons are twin daggers with the same "X" hilts.

Trivia
