He first appears as a business man. He's one of the people captured by Cluemaster in the episode "Q&A", so Arthur Brown would have received his revenge, for the fact that Ross cheated on the show Think Thank Thunk in the way that Yelena Klimanov could win. However, he is stopped by Batman, that then saves Ross and the others.
He later appears in the episode "RPM", as the announcer of Gotham City's race, and never seen again.
