Batman and Robin, e.g. (3)

I believe the answer is:

duo

(Other definitions for duo that I've seen before include "Performing pair" , "A team of two" , "entertainers such as Eric and Ernie" , "Musical work for two" , "Musical pair" .)

I've seen this clue in the LA Times, the USA Today and the Universal.
