Ramone

Ramone was one of River Song's husbands.

He teleported her from Hydroflax's flying saucer to Mendorax Dellora, where she snogged him passionately in front of the Doctor, who was disgusted by the sight.

He was lured into a dark alley by Nardole's head, which was being controlled by Hydroflax's robotic body. The robot then beheaded him and used his head as bait for River to open the TARDIS doors. (TV: The Husbands of River Song)
