- "For years, I held a grudge against a quiz show for dumbing down their answers. My world was so tiny back then, but there's nothing like five years in prison to expose you to all the ignorance and stupidity on this planet. Let's weed them out, together."

Biography
Early life
Sometime before or during 2016, Arthur Brown became the host of a gameshow known as Quiz Bowl and had a daughter, Stephanie. Becoming disillusioned with how the gameshow had begun "dumbing down" the questions, Brown was later fired, leading to him going on a murdering spree as the criminal "Cluemaster" while leaving clues for law enforcement to follow.
In 2016, Sophie Moore investigated Cluemaster's crimes and, thanks to an anonymous tip by Stephanie, was able to thwart and arrest him. Arthur was sentenced to Blackgate Penitentiary to serve 13 life sentences, leaving him to wonder how Sophie was able to beat him.[1]
Revenge

In 2021, Brown escaped Blackgate and went to see Stephanie, hoping that she would be his partner-in-crime; Stephanie denied the request. Brown then knocked his daughter unconscious and began writing in code on her body. Before she awakened, Brown placed Stephanie in a box that could only be opened with gunshots to certain targets in a particular order. Brown poisoned Sophie's drink with a puss caterpillar, one of the most venomous caterpillars in the world, for revenge and left a clue for Sophie to pursue. Deducing the use of the word "hotshot", Ryan Wilder held up a candle to the poisoned glass, revealing an emblem.
Eventually, Sophie, Ryan, and Mary Hamilton managed to find and free Stephanie; who started working with them to discover her father's whereabouts. Later, the trio fell into Arthur's trap on the set of Quiz Bowl. Arthur appears on a screen and gives the women more time by answering the questions on his Gotham Villain quiz. Stephanie managed to decipher Arthur's code and tracked him to their first house. There, Arthur found her and was happy to see that Steph has retained her puzzle-solving skills and wants her to be his partner in crime. Until Steph admits that she was the one who solved his puzzles five years ago and anonymously denounced him to Sophie, to arrest him so he can't hurt innocent people. Then Arthur knocked her unconscious, trapping her and himself in a car to die. However, Luke Fox was able to save them and Arthur was arrested and sent to Blackgate again.[1]
