Detroit pro (4)
I believe the answer is:
lion
'detroit pro' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lion that I've seen before include "King of the forest" , "The -, the Witch and the Wardrobe" , "Cowardly visitor in Oz" , "Courageous person" , "Buddhist scripture; Sanskrit rule" .)
