Leonard wants to bequeath his tattooed skin to the National Gallery of Australia. He has been almost completely inked by one of Australia's best contemporary artists, but he is a canvas that nobody wants. Strange things start happening to Leonard, Darwin's moth, a tattoo from his calf, flutters around him one night, he wakes with a Cold War gas mask on his head, Mao Tse Tung appears in his bed. Tattoos from his skin come alive before him and he becomes more convinced than ever that his skin is truly precious.

A Joker Story - "Definitive Therapy" was commissioned and paid for by DC Comics for an anthology called The Further Adventures of The Joker to tie in with the first Batman movie.
