Harley Quinn Crew Ranks collects achievement-style collectibles tied to Harley Quinn Crew participation and Gotham City story challenges. The ranks reflect activities such as RSVP for Mayhem, personality tests, crew roles, and Harley-themed community missions. Designed for DC collectors who followed Harley’s interactive capers, the collection turns participation, rank, and Gotham mischief into character-driven keepsakes.
