David Gentry, serial number 99B3278, was the identity assumed by a member of Species 8472 in 2375 when that species constructed a re-creation of the Starfleet Command complex in preparation for an infiltration and possible invasion of the Earth. The replicant accosted Chakotay and Tuvok on the grounds of the re-created complex, telling them as they had entered a restricted area. Chakotay and Tuvok were there investigating the re-creation. He was incapacitated by Tuvok using a Vulcan nerve pinch and taken aboard the USS Voyager.
