Early Life: Obsidian A Grimmson was born in Mistral to Kuro and Opal Obsidian, both Crocodile Faunus. Not wanting a child, they took their son into the forest to get rid of him. Unluckily they were killed by two Beowolves. Obsidian was found by an older Beowolf who took him in and raised him, when Obsidian was 7 his adoptive father was killed by four Hunters from Atlas who came to take care of Grimm activity. Forced to grow up in an orphanage he began to use his Semblance, when he got out from being too old and the old owner's death from natural causes. He joined the White Fang as their information/torturer gaining the nickname The Butcher. When in the White Fang he found that he could not continue ripping parts off of faunus or tormenting humans. He staged an elaborate breakout and ran away from the White Fang, where he then chose to focus more on his schoolwork.
