The Graverobber had a bear-like stance and possessed three jawless heads and pincers. The creature's entire upper torso was composed of dead bodies most which are visually absorbed partway into the creature's flesh. Among these corpses are the remains of Ramirez, Samuel Irons and Heather. It also had large, Slasher-like blades. The right blade was obviously formed from a Slasher that was melded into it, or simply a grossly mutated human body.
As it was mentioned above, the Graverobber had three large heads fused to each other. A long, fleshy tongue came out of the central head while two giant mandibles or tusks came out of the heads on the sides. The body of a Graverobber was similar to a Brute that had several armor-plated regions on its body, forming a ribcage-like pattern along the length of its torso.
This Necromorph would find dead bodies and devour them within seconds, probably adding them to its biomass this way.
- In Dead Space: Downfall, the Slashers are seen piling up bodies in the Mess Hall. It was speculated that this was how the Graverobber was created.
- Originally, it would have pursued Alissa Vincent until getting smashed by the Ishimura's Centrifuge. This was likely how the Centrifuge malfunctioned before the arrival of Isaac Clarke. If this was the case, it was still unclear whether the creature was still alive or not as no dead Graverobbers could be seen in the Centrifuge chamber when Isaac came down to fix it.
- The Centrifuge could be observed leading into the vacuum of space when it was functional so it might have been flushed out into space when the Centrifuge hit it.
