Johnny J. Otrix

Johhny J. Otrix, also known in his Court of Owls identity as The Phantom Stranger, or simply The Stranger is (overall) the main antagonist of the third season of Gotham. He is the deceased leader of The Court of Owls, and is Bruce Wayne's great uncle. He has Jerome Valeska and Kathryn as his mercenaries, and Leopald Otrix as his son and henchmen.

Background
He was once the head of The Court of Owls, until being killed by Tha'al Sinestro, who is also Fish Mooney's arch-rival. His son Leopald took his place as the head of The Court of Owls, however, he remained the spiritual leader as a ghost, and he continued running his son's evil schemes.

Eye of The Tiger
His background story is mentioned by one of his mercenaries, Jimmy Zingler, who is caught by James Gordon and his friend, Oswald Cobblepot. Johnny later appears as a hologram in his son's office. Johnny orders Leopald to find Bruce Wayne and bring him alive. Bruce Wayne is brought to Leopald's office, as Johhny's hologram awaits for Bruce's visit. Johnny reveals Bruce their relations, and asks him to join The Court of Owls. However, Bruce kicks Leopald who holds him, and jumps of the window as Leopald's 3 thugs try to catch him. Johhny orders Leopald to find his house, and destroy it, just so he will be forced to live with the members of The Court of Owls, inside their lair.

The Next Flight
Johnny is summoned as a spirit by Jerome, as he is forced out of his grave. Johnny J. Otrix commanded his mercenary, Jerome, to give him all restless souls of Gotham City, and to find him more power. His ghost then disappeared.

The Joker's Gambit
Johnny's spirit reappears, after Jerome brings him dead corpses, including Butch's corpse. He then destroys the corpses, and states that he feels their blood running through his new veins. He then turned into The Phantom Stranger, and he ordered Jerome to revive the lost souls from 1 to 100. When he becomes the new ruler of Gotham, due to Jerome's massive attacks in Gotham, he enters the lair of The Court of Owls (Owlburrow) and orders all of his henchmen (the members of The Court of Owls, who wait for him in the hall of the lair) to make sure Gotham has a new security force.

He then phones his son, Leopald, who tells him they are working on a project which will destroy Gotham in case of massive riots and citizens who fight back. Johnny asked if it is The XBomb, and Leopald replied that it is, and that Luthor is helping him. Johnny then congratulated his son, and ended the call. Johnny, now The Stranger, has then used magic to create a dark cloud over Gotham City.
