A transgender man and his female partner were slashed during a fight with a felon who hurled homophobic slurs at the pair on a Manhattan train early Friday, according to cops and records.

Khleo Finnie, 23, of The Bronx and his 22-year-old partner were on a No. 3 train at 96th Street on the Upper West Side around 2 a.m. when a man in his 40s said Finnie was “dressed like a boy” and called him a “f—-t” and a “b—h,” cops said.

Finnie displayed a knife and menaced the man, police said.

Then the man — who previously served a decade behind bars for manslaughter, according to prison records — grabbed the knife, slashing both Finnie and his partner during the struggle, cops said.

Finnie was cut above his left ear, and his partner suffered a slash wound over her eyebrow and wrist, cops said.

The alleged slasher bolted from the station after the assault but was quickly busted by cops, with charges still pending by the afternoon.

The suspect, 54, has 11 prior busts, six of which were felonies, including two assaults and one from a fatal incident in 1991, police sources said. The details of that case were not known. He was released from prison on parole in 2003, according to state prison records.

Witnesses showed video to authorities indicating that Finnie had the knife first, according to police.

He was also taken into custody and charged with second-degree menacing.

Hours earlier, two men were slashed on the 2 and 3 platform of the Central Park North–110th Street station, cops said.

The violence erupted after one of the victims got into a dispute with the suspect, who pulled out a knife and slashed the man’s left arm shortly before 8 p.m., law enforcement sources said.

As the culprit fled, he slashed a second man in the left forearm before running off, sources said.

The assaults come amid a recent spate of violence in the city’s subway system.
