John Coffey is an African-American man who is put on deathrow in the 1930's. Not long after being convicted, Coffey shows he has a miraculous healing ability by instantaneously healing Paul Edgecomb's urinary tract infection. He also heals Mr. Jingles, Eduard Delacroix's pet mouse, after Percy Wetmore steps on him in attempt to kill him. John is very large, having to duck under most doors. He has a mind similar to a child. He once claims he can only spell his name. He is mild mannered, calling everyone Sir or Ma'am, on one occasion. Whenever he heals someone, he exhales a strange insect-like thing, and [in the movie] the lights flicker. He on one occasion used Percy for vengance against William "Wild Bill" Wharton, and for what he did.
- His initials are similar to Jesus Christ's (J.C.)
He has an innocent, child-like mind
