(Capcom's primary storyline)
The Grave Digger reproduces by laying eggs in the sewers and inside the ground, often in bunches of a hundred. Under these infected conditions, these eggs soon hatch, often in 2 hours, and the resulting creature is known as the Sliding Worm.
These larvae are another kind of irregular mutant, usually growing to about 1 meter in length, and possess sharp fangs, and an elastic, flexible body. These creatures thrive on blood, and when they spot prey, they will leap towards it with amazing jumping power, and suck blood from it like a leech, sometimes as much as one litre.
