Davian is the most infamous black market dealer who commonly makes use of specialized micro-explosives which, once planted in the skulls of hostages or exposed undercover agents, enable the disposal of an individual with ease without harming others. Davian's plan is to ultimately find and sell a dangerous mystery item known only as the Rabbit's Foot to terrorist extremist groups for profit.
Ethan Hunt goes on a mission to capture Davian and initially succeeds, but Davian is soon broken out of custody and manages to escape. He then kidnaps Ethan's wife Julia before calling Ethan, telling him he has 48 hours to recover the Rabbit's Foot for him or else Julia will die. Ethan finds the Rabbit's Foot and contacts Davian, but Davian seemingly kills his wife anyway. This is later revealed to be Davian's head of security in disguise, as Davian had wanted to make sure Ethan was in fact telling the truth.
Davian then leaves, but Ethan overpowers one of his men and tracks the location of his last phone call. This leads him to a small building where Davian has the real Julia tied up. As Ethan goes to free her, he is attacked by Davian. After a brief fight, Ethan shoves him through a set of glass doors and out onto the road. Davian is then run over by a speeding truck, killing him and leaving only one of his shoes in its wake.
