Garment behind a superhero's back (4)

I believe the answer is:

cape

(Other definitions for cape that I've seen before include "Cod possibly" , "Garment - promontory" , "Notorious Chilean headland" , "Sleeveless garment like a cloak" , "Covering for the shoulders" .)

I've seen this clue in the Newsday.
