Stalker

As the Greed layer's punishment, Stalkers have been forced to carry heavy boulders up the monuments of mankind's greed for all eternity. They have carried out their punishment for so long that their bodies have evolved, warped and grown to better suit it. Their limbs have twisted to give them better balance while carrying boulders on their backs and their skin and muscles have completely dried up, allowing them to survive direct contact with the dunes of gold dust that Greed's sun has raised to unfathomably high temperatures. However, an unidentified sentient force has replaced the boulders they would normally carry with high tech bombs that, upon detonation, will transform any nearby blood into the gold dust "sand" that covers the layer's surface. Research has shown the technology to be very similar to the augmentations of the modified Strays known as Soldiers, so it is likely both modifications come from the same source.
