I was referring more to the fact that the 70s Joker (Phoenix) would exist as an iconic figure in the present-day of The Batman, and therefore, it wouldn’t be strange for modern gangs to be paying homage to him, like a Che Guevara figure. The ending of Joker suggests pretty strongly this will happen.Quoting Henry Gale (view post)
Edit: not to say that’s what’s happening here, as the gang’s makeup isn’t overtly clownish in the Joker sense.
