Drebin 893 is one of the many members of a group called "Drebin", a huge network of underground gun launderers who replace ID chips in guns so they can be used by anyone. This Drebin helped out Philanthropy in their mission to take down Liquid Ocelot, but unknown to them Drebin was helping The Patriots by encouraging them to take him out.
Drebin met Solid Snake early on in his mission in the Middle East, and tells him about his gun laundering activities, claiming to be an employee at ArmsTech Security. After giving Snake an M4 Custom as a "welcoming gift", he tells Snake about the War Economy, and how one day it will plunge the entire world into war.
He next meets Snake in South America, and tells him about The Beauty and the Beast Unit, and later on comes to Snake and Naomi's rescue when Naomi is seconds away from being taken by Vamp. He also comes to the rescue of Snake, and Meryl Silverburgh's Rat Patrol in Eastern Europe after they were nearly killed by Liquid Ocelot. Lastly, he is seen by Snake and Otacon on the Missouri where he tells them that thanks to Liquid Ocelot disabling the SOP System, his sales have gone up.
The Drebins' catch phrase, as seen on the side of his vehicle, is "Eye Have You." Drebin 893 seems to enjoy tricks involving sleight of hand with his white piece of cloth, procuring an apple and a hand grenade upon his first meeting with Snake. He also enjoys Narc Soda, and has a companion monkey named Little Gray who also enjoys Narc Soda, and cigarettes, thanks to Old Snake. Throughout the game, Drebin 893 also provides Old Snake with details to the traumatic backgrounds of each member of the "Beauty and the Beast Unit".
