rogue

I'm a little stuck... Click here to teach me more about this clue!

'villain' is the definition.
(rogue is a kind of villain)

I don't understand the remainder of the clue.

(Other definitions for rogue that I've seen before include "Baddie" , "Dishonest chap; solitary (elephant)" , "Dishonest man" , "Profligate" , "Scoundrel, knave" .)

I've seen this clue in The Globe and Mail.
