The Cleric Beast is a hideous, malformed creature encountered in Bloodborne that functions as the first technical boss of the game. It is a massive creature that appears to be malnourished and dying, although it maintains superbly superhuman abilities.
It has been speculated that the Cleric Beast is likely a former clergyman of the Healing Church (and a reasonably high ranking one at that), such as a Hunter or something of the sort. This is supported by the fact that Laurence, founder of the Healing Church, became a Cleric Beast of fire inside of the Hunter's Nightmare.
It can be assumed from the size of Brador's helmet (made out of a slain Cleric Beast) that these creatures have grown in size tremendously since the beginning of the scourge, and thus have become far more dangerous.
