Did you know the four of the Jokerz from Return of the Joker are inspired by certain people or looks?
Eric Radomski, co-creator/producer of Batman the Animated Series arrived at a who came to a Halloween party dressed in an outfit and mask that stuck out to the creators of Batman Beyond. Dubbed humorously as “Sicko the Clown”, he became the inspiration for Chuko.
Ghoul’s appearance was loosely based off of the classic Batman villain, the Scarecrow. While it is unknown if this was intentional or not, in Batman Beyond 2.0, Ghoul began to show his skills as a chemist, much like Jonathan Crane. Woof was also inspired by something from classic Batman, as the Joker’s pet hyenas, Bud and Lou.
