Character with edge in game (9)
I believe the answer is:
partridge
'game' is the definition.
(game bird)
'character with edge' is the wordplay.
'character' becomes 'part' (a part in a play).
'with edge' becomes 'ridge' (I can't justify this - if you can you should give a lot more credence to this answer).
'part'+'ridge'='PARTRIDGE'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for partridge that I've seen before include "Flighty type" , "early Christmas present" , "Peculiarly apt girder for the game bird" , "Animal" , "sort of quail" .)
