Arthur Penn

Arthur Penn, also known as The Ventriloquist, is a recurring character in the television series Gotham, who appears as a supporting antagonist in season 5. He appeared as the mob accountant to Penguin, who also shares alliances with Carmine Falcone and Sofia Falcone. During the fifth season during the No Man's Land event, he is seemingly killed off for real, but returns later on in which he is revealed to be the show's version of the Batman supervillain The Ventriloquist.

Trivia

 * Despite working for Oswald Cobblepot/Penguin throughout season 4 and the beginning of season 5, he isn't portrayed as an antagonist and is simply his accountant, and appears quite timid and harmless. Following his resurrection later in season 5 however, he will appear as a villain when revealed as the Ventriloquist.
 * The original Ventriloquist in the comics is Arnold Wesker, whom Arthur Penn shares a likeness to and is most likely inspired by.
 * Penn is the fourth Gotham character to be introduced as a seemingly original character in the show, only to be revealed as a canon character from the DC Comics. The previous three are Butch Gilzean/ Solomon Grundy, Theo Galavan/ Azrael and Nathaniel Barnes/ The Executioner.
