Lieutenant Trotter is a Security Officer in the Department of Domestic Security's paramilitary Vigilante Registration Agency division and a recurring antagonist in Season Ten of the CW TV series Smallville.
She was portrayed by Lori Ann Triolo.
She was formerly Lieutenant General Slade Wilson's aide. Trotter attended a meeting with Slade and several other key military officers that discussed the Vigilante Registration Act. Slade proclaims that the country's safety depends on it and the President has put him in charge of overseeing the bill's execution. After Oliver Queen registered with the act, he was taken to a holding facility that house captured super-powered beings regarded as vigilante. Trotter aided Slade who managed to capture Oliver and Aquaman as well. The facility was destroyed and the heroes were freed with Slade vanishing in the explosion.
After General Slade's disappearance, Lieutenant Trotter apparently became head of a DDS strike team operation. First they tightened security at the Daily Planet and everyone had to go through metal detectors and searches. Tess Mercer was having lunch when she was confronted by Cat Grant for not running the story about Oliver and the VRA, but Tess dismissed her. A government agent then arrives to bring Tess in for questioning about the vigilantes. After reading a government ad demanding information about the heroes, Lois walks into an elevator at the Daily Planet. Lieutenant Trotter confronts her and brings her in for questioning. Trotter interrogates Emil, Lois, and Tess separately at the Daily Planet, but none of them give her the answers she was looking for, much to her frustration.
Since they wouldn't give up any information, Trotter planned to take Tess and Emil to a warehouse to continue being interrogated, or presumably to be executed, but were saved by Clark Kent.
After the Justice League attended Hawkman's funeral in Egypt, they were rendered unconscious when a mysterious white pyramid object rose and flashed a blinding light throughout the room. The Vigilante Registration Agency captured The Blur, Black Canary, Green Arrow, Stargirl, Impulse, and Lois Lane at the funeral of Hawkman in Egypt and placed them in a virtual dream world while they tried to find out how their special abilities could be controlled. They awoke in the "reality" wondering why they had not powers and how they got free.
