I'm trying to identify this minifigure for my son. It came from a bundle of mixed sets. I initially thought it was from the Super Heroes theme, but I've checked all the Super Hero minifigures on BrickLink and been unable to match it. Note, the minifigure's torso is blank on the back. Thanks.
The head is 3626cpb1091 AKA "Nightwing with red eyes". It only appears in one set, 76011-1 Man-Bat Attack:
The torso is 973pb0714c01 AKA "torso witch with green belt". It only appears in set 850487-1 "Halloween Accessory Set" and as a collectible minifigure from Series 2:
The legs seem to be plain black legs, way too common to pinpoint their origin.
