I was thinking about Stephen King characters with disabilities - partially because he tends towards "magical disabilities" (or, sometimes, for a change, "creepy disabilities") in his fiction, and so a lot of them could use some fic to fix these problems! I thought of:

Nick Andros (The Stand)
Tom Cullen (The Stand)
Leo "Joe" Rockway (The Stand)
Donald Merwin Elbert, "The Trashcan Man" (The Stand)
Polly Chalmers (Needful Things)
Danforth "Buster" Keaton (Needful Things)
Nettie Cobb (Needful Things)
Slopey Dodd (Needful Things)
Dinah Bellman (The Langoliers)
John Coffey (The Green Mile)
Paul Sheldon (Misery)
Jack Torrance (The Shining)
Danny Torrance (The Shining)
Johnny Smith (The Dead Zone)
Seth Garin (The Regulators)
