Harley was the pet monkey of the Jester.

Named after the Harlequin, Harley is dressed like the Jester, in a distinctive gaudy jester outfit. Much like the character, Harley is acrobatic and nimble. She appears to also have an affinity with Alexander Luthor. He relayed to her the Jester died in combat against the Crime Syndicate when he and the Justice League used an old hideout to plan out their next move.
