Gregg the Grim Reaper is a diminuitive representation of Death in the game Conker's Bad Fur Day (along with its remake Conker: Live and Reloaded.) He first appears when Conker initially dies, describing Conker as one of the "special cases." He explains that Conker has as many lives as he has squirrel tails, a short description of the lives system throughout the game. Afterward, Gregg drops Conker back into the world of the living. At any time that Conker dies (and has the required squirrel tail) Gregg will drop him back close to where he left off.
Gregg uses a voice-changing megaphone at his initial appearance, eventually discarding it, revealing his own nasally voice.
Gregg is known to hate cats, most likely because of them possessing nine lives instead of one. He can be seen attempting to attack catfish with his scythe in the Spooky chapter.
