Davidov was in effect Elektra King's right-hand-man, as he is in charge of her personal security and also meets with Renard regularly. After Renard's men fail to terminate Bond in a staged attack upon the King pipeline, Davidov is brought before Renard to answer for the mission's failure. Dr. Arkov urges Renard to abandon the rest of the operation for fear that the failed attack will raise too much suspicion of them, and blames Davidov for the incident. Renard seemingly orders his execution, but instead spares him and murders Arkov instead. He takes over Dr. Arkov's job of infiltrating the nuclear decommissioning site but only makes it as far as the airport. After having his devotion to the cause tested by Renard and his scalding hot rocks, Bond discovers Davidov's affiliation and shoots him twice before dropping him into a trash skip. He then assumes Davidov's place in infiltrating the strike team Renard sends to steal a nuclear warhead in Kazakhstan. Davidov's body is discovered by local authorities some time later, giving Elektra further pretense to ask M to come to her aid before her later betrayal of MI6.
