Black Worms are huge alien worms that appear as enemies in Shadow the Hedgehog. These Black Arms creatures are found in various stages and will erupt from beneath the ground when Shadow approaches. They attack by swinging their heads and also by spewing small blue worms from their maws. These blue worms act as homing projectiles and explode on impact.
The weak spot of the Black Worm is the maw and Shadow can kill them fairly quickly by shooting them with rapid-fire weapons when their mouths are open.
