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.
After the Doctor destroyed the onboard computer of Hydroflax's body, Ramone and Nardole gained control of the body. The two shared control of the body and worked as a waiter at Alphonse's restaurant in front of the Singing Towers of Darillium. When River arrived years after the crash of the Harmony and Redemption for her final date with the Doctor, Ramone greeted her and reassured her that Hydroflax's body was no longer a threat as the computer had been "deleted in a merger."
