Fossor

Recent studies by the Whitestar Institute reveal that some Ethereals' limbs carry notable features from their environment. Fossor is a prime example of this — its strange forelimbs bear a striking resemblance to the drilling equipment found in the Old Oil Field region. Although some suggest this is a camouflage tactic to deceive enemies, others have pointed out that Fossor's combat style is aggressive and direct, making it appear ill-suited for ambushes. Some imaginative Hollow Raiders speculate it may have developed this form just to dig for minerals… "When I caught sight of it from a distance, it seemed to be happily digging up the asphalt." "When it spotted me, it didn’t hesitate to charge straight at me, desperately trying to drive me away…" "But I was just passing by! I had absolutely no intention of taking any of its junk!" — A rookie Hollow Raider outside a Hollow, recounting his recent experience to his companions
