Subject 514A

Subject 514A, also known as Bruce Wayne's doppelgänger, is the clone of Bruce Wayne created by the Court of Owls in order to replace him. He appears as an antagonist during the third season of the Fox television show Gotham.

Background
Subject 514A was created as a clone of Bruce Wayne at Indian Hill by Professor Hugo Strange on the orders of the Court of Owls. He was kept at the facility underneath Arkham Asylum along with other experiments belonging to Hugo Strange.

Season 2
514A and other monsters were put on a prison bus to be transported to an upstate facility on the orders of the Court of Owls. However a resurrected Fish Mooney hijacked the bus in order to make her escape and ended up crashing it in the streets of Gotham. An old homeless woman heard the cries of the prisoners and taking pity unlocked the door, and was horrified at the monsters leaving the bus. 514A stood over the woman and thanked her, before venturing into Gotham with the other escapees.

Season 2
The clone took an interest in the real Bruce Wayne and approached Ivy Pepper about him, which freaked her out and caused her to flee.

The clone arrived at Bruce's home Wayne Manor, much to the shock of Bruce and his butler Alfred Pennyworth.
