Mario Calvi

"His name shall be neither spoken nor taught. He'll cut and he'll crush and the blood will run thick. Though from healer to killer is no easy trick."

- Jervis Tetch about Mario Calvi

"You know what, Jim, with all this virus talk, you keep forgetting one thing: I'm still Carmine Falcone's son."

- Mario Calvi to James Gordon

Mario Calvi, or Mario Falcone is a supporting character turned antagonist in the third season of Gotham and the main antagonist of the episode Beware the Green-Eyed Monster. He is the eldest son of Carmine Falcone. Originally a supporting character, Calvi was a doctor at Gotham General Hospital who became the fiancé of Leslie Thompkins after she had broken up with James Gordon, following his incarceration to Blackgate Penitentiary.

Although Calvi and Gordon initially had a favorable friendship, Calvi - while trying to rescue Gordon from dying from a hallucinogen - was injected with the Tetch Virus by Jervis Tetch. Although he had remained being infected a secret, he grew jealous over Lee's small love for Gordon and orchestrated multiple events to make it look like Gordon was sabotaging his and Thompkins' wedding.

He was portrayed by James Carpinello.

Fatal Encounter with James Gordon
At Carmine's refuge, Calvi begins to ponder on Thompkins' feelings for Gordon. Thinking that she loves him, his heartbeat begins to amplify and proceeds to grab a knife, slowly walking towards her. James Gordon, who had arrived at the refuge to kill Calvi turns to find him just seconds away from killing Thompkins, who is oblivious to the fact. Gordon fatally shoots him twice, saving Lee but also whisking away the evidence - the knife - into the river that ties him to her attempted murder.

His ultimate fate is left unknown.
