Detective Lucas Hilton (died December 11, 2013) was a police detective of the Star City Police Department and the former partner/good friend of the late Quentin Lance. He was also the husband of Jeannie Hilton.
At the Queen Mansion, Lucas Hulton and Quentin Lance questioned Oliver Queen and Tommy Merlyn about their recent kidnapping. Oliver claimed "a man in a green hood" saved them, which Lucas and Quentin were initially skeptical of. Lucas informed the Queen family that they were unable to identify the kidnappers, as the group's identities were scrubbed and they used untraceable weapons.
The next morning, the Lucas and Quentin learned from Adam Hunt that a man matching Oliver's description attacked him and his bodyguards. Realizing Oliver was telling the truth, the two agreed to coordinate with Adam's security to capture the vigilante and stood guard outside Hunt Multinational that night.
At 10:00 pm, Adam alerted the police to the vigilante's presence. Lucas, Quentin, and their team stormed inside Hunt Multinational but vigilante escaped. Lucas and Quentin tracked him to a neighboring building, where Oliver's homecoming party was being held, but were unable to find the vigilante. Lucas calmed Quentin down when he became angry at Oliver and they left.
Lucas and Quentin investigated the scene of James Holder's murder with a poisoned bullet. Lucas wondered if The Hood had simply changed his modus operandi of killing, since they recovered his arrows, but Quentin was unsure. Later that day after receiving the ballistics report, Lucas informed Quentin that Holder had been killed by curare-laced bullets, voicing his belief that The Hood was still involved somehow.
Lucas was eventually killed by Cyrus Gold after he tried to capture Cyrus, who made Lucas shoot himself in the head.
In the alternate reality created by the Dominators, Lucas was still alive. Just like in the real world, he was an SCPD detective and Quentin's partner. After Robert and Oliver were saved by The Hood from a mugging, Lucas was mentioned to have reported this to Quentin.
Lucas received justice for his death when Cyrus Gold was killed by the Arrow.
