Alien (Spielberg's War of the Worlds)

This is an unnamed alien species which emerged from below the surface of the Earth to invaded Earth in the early 21st century when activated by activity similar to lightening strikes on their position which served as their call to activate. [1] The species has apparently been below ground for ages and it's not known when they first arrived on Earth or how they sustained themselves all these years.
