Season 3

Jerome in action

He returns and is at first seen throwing a grenade on some people, while Bruce Wayne actually witnesses his return to Gotham. He then enters Lex Luthor's office and he hires Luthor to revive an evil organization named The Lost Souls. Later, he puts knock-out gas into a museum hall, and he steals the mask of The Joker.

Later, he uses dark power on people alongside his henchmen, Gerald McMonnus, and bombs up The City Hall, killing dozens of people and GCPD members. He then entered the Lexcorp-X factory and asked Lex Luthor how The Lost Souls are doing. Lex replied that they need some more crystal operations to become all powerful. Jerome and Lex then entered a museum owned by Max Shreck, and have stabbed Max, thus testing his own crystal on Fish Mooney. Fish then turned into Hypnotisis, and Jerome Valeska ordered her to "spread Gotham's favourite virus". He then created an army of lost souls, and ordered them to terrorize Gotham everywhere. The lost souls were seen destroying GCPD buildings, bombing houses and stalking people on the street. Jerome then managed to kill Oswald Cobblepot, which he met on the empty street at night. He then took Oswald's plans for building a chemically designed nuclear-like bomb called The XBomb.

Jerome later captured James Gordon and revealed him that he plans to return a favor to The Court of Owls, since they have helped him get away, after killing his own parents. He then shot Gordon, and left before Gordon was found and sent to hospital. He later bombed the building of The Wayne Enterprises, and he declared war on Gotham on the news camera, as behind him the building was exploding. He later went to the cemetery, and summoned the spirit of Johnny J. Otrix, the deceased leader of The Court of Owls. Otrix ordered him to find more power, and posses more restless souls in Gotham City.

Attack on Gotham and death

Jerome later appears in his Joker mask, thus he kills Butch for betraying his ally, Fish Mooney. He brings Butch's corpse, as well as many other corpses of people he had killed, to Johnny Otrix's grave. Johnny destroyed the corpses, and used their blood to become The Phantom Stranger, a powerful sorcerer who can do any dark magic. Jerome later revives 100 people as empowered members of The Lost Souls. He orders them to attack Gotham's plaza. As the 100 lost souls attack Gotham City's central plaza, he stands on the rooftop, and James Gordon fights him. However, in the middle of the battle, he jumps off the roof, and uses a parachute to land. Lex Luthor then comes and attacks Gotham City with his spaceship. Jerome and Johnny then took over Gotham, as Johnny became it's new ruler. Gordon however did not give up, as he tracked Jerome's location, and went to fight him in the ruins of the plaza. Jerome then revealed Gordon he has Barbara as his hostage, and that he plans to kill her. Jerome and Gordon had a rough sword-fight thereafter, and Gordon falls on the floor due to Jerome stabbing him with a sword. Jerome then picked up the sword to finish Gordon off, however, Gordon kicked him, and from behind, an injured Theo Galavan came and stabbed him with a sword. Theo stated he needs help from Gordon, as he just wants to put an end to the mess and become mayor again. Gordon got up with all his strength and stabbed Jerome's head with a sword, causing Jerome to fall to his death.


Jerome was a remorseless, unpredictable and utterly psychopathic boy with a deep enjoyment of wanton and needless acts of violence and chaos, committed by him and the Maniax or just in general. In the third season, he becomes more ambitious, as he is revealed to work with The Court of Owls.
