The largest and most massive unit within the Swarm force, it is massive at 60 feet long with a diameter of 18 feet. It will slam down with its head when above ground and has both a plasma blast shooting a plasma blob far distances while keeping enemies at range using its acid breath. When it is killed in battle it releases a horde of Larvae which burrow into the ground for later Swarm use. This has become a new form of invasion, the Black Fleet will fill a large rock with a few of these worms and hurl them at a world with other meteors to mask its descent. If the world's forces are unable to detect and kill the worms, upon impact they will rapidly dissolve into the ground supplying the burrowed Larvae with enough biomass to create a massive swarm within days.
