The outlaw father of Eli Hollander in Alexander's Western holodeck program, who took on Data's appearance after a computer malfunction.
Frank Hollander is a villain in the Ancient West holodeck story that Worf and Alexander play together. He rides into the town of Deadwood to free his son Eli, the Butcher of Bozeman, whom Worf's sheriff has arrested.
In A Fistful of Datas, an experiment linking Data to the ship's computer causes Data's features and abilities to replace those of several holodeck characters, Frank included. With the safety protocols failing, Frank becomes a dangerous opponent, and Worf must defeat him without being able to end the program. He was played by Brent Spiner.
