Cluemaster (Matsudaverse)
Arthur Brown, better known as Cluemaster, is a minor antagonist of the 2004 animated series The Batman. Arthur was a child prodigy, one who competed on a gameshow for children with high intelligence called Think, Thank, Thunk, and won 17 weeks in a row. His streak ended after getting a question wrong and blamed the host Ross Daren, producer Herbert Ziegler, and his opponent Yelena Klimanov for this and sought revenge years later.
Cluemaster was voiced by the late Glenn Shadix who voiced Tso Lan and Xiao Fung in Jackie Chan Adventures.
