Constance Goodheart was the faithful secretary and love interest of Captain Proton. She was the "Daphne" of the group, whose purpose was to scream, get kidnapped, and then scream some more. Her personal vocabulary would appear to consist of a series of variable pitch screams. (ST - Captain Proton: Defender of the Earth short story: "Children of the Glass")

Constance was also a character in the Captain Proton holonovels devised by Tom Paris aboard the USS Voyager (VOY episode: "Night"). Shortly after Voyager's return to the Alpha Quadrant in 2378, Lieutenant Candace Roske - assigned to guard Voyager while it lay in drydock - altered the Captain Proton holoprogram and took the role of Constance Goodheart for herself, adapting the character into a heroine every bit the equal of Proton. During Admiral Janeway's infiltration of Voyager, Tom Paris (as Proton) incapacitated Roske (as Goodheart) in order to disable the ship's security force. (VOY novel: The Farther Shore)
