When Meg gets a job with the TSA thanks to Quagmire, Larry admits she is the prettiest girl in the TSA and eventually asks her out, incurring Marla's wrath when he suggests that should just be ugly friends. She confronts Meg and challenges her to a fight. When Meg gets the better of Marla with an improvised blowtorch from confiscated items, she vows revenge. Later, Larry confronts Meg about missing security tubs and finds them in her locker, firing her.
Marla is voiced by Alex Borstein.
