Lucas "Luke" Troy is Sterling Archer's former best friend and the main antagonist of the Archer episode "The Wind Cries Mary".
After faking his death, Luke invites Archer to a fixer-upper home in Vermont, which he plans to turn into a bed and breakfast with millions in stolen bearer bonds. He also has romantic feelings for Archer that border on an obsession, and tries to kill Lana and Cyril when they come to Archer's rescue. After Lana drops a tree trunk on him, he confesses with his dying breath that he did something unspeakably depraved to Archer while he was passed out drunk once. The audience doesn't find out what this act was, but Archer and his friends are visibly traumatized from hearing about it.
