Black Death was the second hive-mind of the Black Arms. Originally left behind on another planet to finish an earlier conquest, Death took over his creator Black Doom's role as hive-mind after Shadow the Hedgehog betrayed him and destroyed the first Black Comet. Black Death then led the last of his kind to Mobius to exact revenge on the hedgehog and his allies. Ultimately, the invasion was prevented before it could begin, and Black Death met the same fate as his predecessor: being killed at the hands of Shadow.
