Outlaw peer, odd as can be (9)
I believe the answer is:
desperado
'outlaw' is the definition.
(desperado is a kind of outlaw)
'peer odd as can be' is the wordplay.
'can be' indicates anagramming the letters.
'peer'+'odd'+'as'='peeroddas'
'peeroddas' is an anagram of 'DESPERADO'.
(Other definitions for desperado that I've seen before include "Reckless criminal" , "Road speed (anag.)" , "Reckless guy" , "Bravo" , "Wild ruffian" .)
