A sentient, massive entity which threatened Earth in 2271, en route to find its "Creator." In doing so, V'Ger destroyed anything it encountered by digitizing it for its memory chamber.
Generating a power field "cloud" about itself of over 22 AUs in diameter, the entity had gained sentience after unknown aliens repaired the old Earth space probe that formed its core — Voyager 6, whose name in corrupted English gave the sentience its name.
The entity, which viewed organic lifeforms as carbon-based units "infesting" starships, later joined with Starfleet's Lt. Ilia and Cmdr. Will Decker and evolved into a higher, yet unknown lifeform.
