7) He Once Had Another Sidekick
The Joker’s definitive sidekick is, of course, Harley Quinn – the criminal’s jester-outfitted moll who originated in Batman: The Animated Series in the 1990s. Long before Harley was just a glint in Paul Dini and Bruce Timm’s eye, however, the Joker had another sidekick…one who has not stood the test of time so well.
In the 1960s, Joker was frequently joined on his schemes by his midget manservant Gaggy Gagsworthy (no, really). Interestingly, his origins are tied in with Batman’s own sidekick, Robin AKA Dick Grayson.
Gaggy was originally a tightrope walker at a circus, until he was fired in favour of the Flying Graysons. Gaggy was then forced to work at a freakshow and was left resenting the family that put him there. Can you blame him?
In recent years, he briefly returned to battle Harley and prove he was the better sidekick. Needless to say, Gaggy lost.
