Lieutenant Trotter is a Security Officer in the Department of Domestic Security's paramilitary Vigilante Registration Agency division.
She was 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. Chloe Sullivan entered the virtual reality and went to them one by one explaining that the world was fake. Trotter and the task force were four clicks away from their headquarters and she ordered them to move in. Chloe is working at the computers when the VRA breaks in and Trotter knocks her out.
She has one of her men take over Chloe's avatar. It goes to the Planet as Clark and Lois prepare to jump into the portal. It goes to the Planet as Clark and Lois prepare to jump into the portal and Trotter left the place with a tie-hand Chloe. Outside she gave the order to kill Chloe. However she was rescued by Oliver and the Suicide Squad, with Deadshot firing at Trotter men.
Trotter was confronted by Black Canary and the two women started to fight. Canary avoids Trotter's fire but Dinah won the fight until she runs out of ammo as she defended herself well against Trotter who then knocked her out with her Canary Cry. It was later revealed that Trotter and her men were trapped in the virtual reality, ensuring she could not expose Clark's secret identity.
