My name is Leonard, an interactive, artificial consciousness programmed to operate this vessel's critical systems. 
- —Leonardsrc
Leonard is an AI of the Waverider from Earth-74.
History
Leonard was an artificial intelligence built into the mainframe of the Waverider, that was once owned by the Legends of Earth-74. Its purpose was to look after the Waverider's essential systems and it had a humorous personality. When the Legends retired, Mick Rory took the ship, becoming one of the AI's few companions as Mick used the solitude to become a writer of romance novels.
When Harbinger came aboard the ship to convince Rory to save the multiverse, Leonard announced his presence and warned her that she was trespassing, before asking how she wanted to die. After Mick showed up, Leonard mocked him and his lifestyle in front of her. She eventually convinced Mick to let her accomplices use the Waverider in return for accompanying them in saving the multiverse.
Leonard announces the destruction of Earth-1 on board the Waverider.
He was destroyed alongside the Waverider when Anti-Monitor's anti-matter wave destroyed the Waverider and Earth-1.
Notes
- Leonard was voiced by Wentworth Miller.
