She was portrayed by Caroline Munro.
Naomi first appeared introducing Professor Markovitz and Dr. Bechmann to Stromberg as the latter congratulates the two for building a submarine tracking system before having them killed in a helicopter crash to cover his tracks.
Naomi later meets Bond and his partner Anya Amasova when she is sent to take him to Stromberg's underwater lair called Atlantis. After a brief tour in the lair, Naomi shows them the model of Stromberg's ship Liparus, which gets Bond's interest and he noticed something strange with its bow before leaving. As it turns out, the Liparus has its bows designed to capture submarines as part of Stromberg's plan to instigate a nuclear war so that he can rebuild a new civilization under the sea.
Later, when Bond and Amasova are driving in their car, they're pursued by a motorcyclist and another car driven by Jaws and several of Stromberg's thugs. After all of them are defeated a helicopter arrives, flown by Naomi, who smirks and tries to gun both Bond and Amasova down. To evade her, Bond and Amasova drive off a cliff into the water. Bond then activates a button on the car, turning it into a submarine. He then presses a button which ejects a rocket that hits Naomi's helicopter and blows it up, killing her instantly.
