All it takes is one bad day to reduce the sanest man alive to lunacy.

Why don't you understand?! You need me! I'M THE ANSWER TO YOUR LIFE'S QUESTIONS!! Without me, you're just a joke... without a punch line.
~ Jeremiah Valeska's breakdown to Bruce Wayne shortly before falling into a vat of chemicals.


Jeremiah Valeska, also known as Xander Wilde and "The Joker" in some promotional media, is one of the main antagonists of the TV series Gotham, acting as the main antagonist of the final four episodes of the fourth season and one of the two main antagonists of the fifth and final season. He is Jerome Valeska's twin brother.

Along with Jerome, Jeremiah is an interpretation of Batman's archenemy The Joker, and will take on more elements of the character before finally becoming the fully formed character.

Jeremiah is a terrorist, criminal and murderer. He is also the more arrogant and obsessive identical twin brother of the anarchistic cult leader, Jerome Valeska. After Jerome's death and being exposed to his altered chemical laughing toxin driving him to insanity, Jeremiah takes over the role of main antagonist for the final arc of Season Four and a major antagonist in Season Five. 

He is portrayed by Cameron Monaghan, who also portrayed Jerome Valeska in the same franchise.
