He was born in runeclan camp, a few moons before Runeclan was attacked and again forced out of the territory. But, Metalvoid and his sister, where conjoined twins, making it difficult for the two. Metalvoid had always been rude to his sister before one day, a day after they had joined Spark Clan. Bonethorn/kit had ran off. So, Clearpaw and Metalvoid left to find him. But instead of finding their brother twolegs captured them and split the twins apart. But, when they let Clearpaw go they refused to let Metalvoid go. Instead they did things to metalvoid. Giving him his black and gold eyes and his odd teeth and mane. When he had managed to return, as the deadly cat he now was, he saw Nettlestar dead, Bonethorn adopt thornkit and his mother on the verge of death. Eventually Runestar died, twolegs had killed his mother. But his sister had dragged the mother back after not accepting Metalvoids help. After that day Metalvoid became the leader of the dark forest, other cats joined him in his trouble making ways. His first murder with his beloved Winterbreeze succeeded greatly. He had hung and torn a cat open in a tree.
He was satisfied but sadly he and his family left. Metvoid briught blackit, his adopred brother with him. Leaving his soster who drove him to evil, behind. After that he lived a happy and calm life in Roseclan. No murder, no hatred just calm happiness and relaxing peacefulness.
