Black Arms

The Black Arms are creatures that appear in Shadow the Hedgehog. They are a violent race of hive mind-like extraterrestrial beings led by Black Doom who traverse space in the Black Comet, seeking to consume the entire populations of planets. Fifty years after the creation of Shadow the Hedgehog, they invaded earth in search of the seven Chaos Emeralds, and are opposed (or aided) by Shadow and other characters. They are easily recognized by their black-and-red skin pigmentation.
