Knight of Remnant
"Today, Onyx Rose dies. In his place, Onyx Mercer rises." Those words still echo in his head, the day he disowned that wretched Rose name, and was reborn.
Onyx Rose is the adopted child of Summer and Tai, and goes through hell. Beaten everyday for minor things or even things he didn't do. His sisters hate him and blame him for everything, Qrow gets drunk and hits him, Raven insults and taunts him. No more. After years of preparation, Onyx escapes, and returns stronger than team RWBY and STRQ put together.
