Grave Digger Render.

The Grave Digger is a giant mutated millipede that appears as a boss in Resident Evil 3: Nemesis. Produced by secondary T-virus infection, this creature grew to tremendous size and its burrowing caused a number of localized earthquakes beneath Raccoon City. It developed four large mandibles around its mouth to pull in prey and would feed on any warm-blooded creatures it encountered.

Jill Valentine encountered a Grave Digger in Raccoon Park and was able to kill it, though it is likely that there was more than one of the creatures active during the Raccoon City Destruction Incident. The Grave Digger also produced offspring called Sliding Worms that Carlos Oliveira encountered at Raccoon Hospital.
