A vicious
alien species from the Doctor Who
spin-off, Torchwood, the Weevils' origins (planet, species, etc.) are unknown. The only knowledge acquired is the fact that they, like a lot of other remnants of various
extra-terrestrial life and technology gathered by Torchwood, did not come to this planet on any form of ship or teleporter, but were spilled onto this planet from the dimensional rift running directly through Cardiff, Wales, where the Torchwood-3 facility (helmed by Captain Jack Harkness) is stationed to monitor and contain rift activity. Upon a Weevil's arrival, they generally migrate to the sewage systems and keep out of sight. Unfortunately, Weevils are carnivorous and tend to occassionally wander to the surface to prey on
innocent victims. The Torchwood team can
track the Weevils and subdue them with a patented
Anti-Weevil
spray before encarcerating them in the containment cells at the central
hub. It was later discovered that, originating from the rift, Weevils are highly sensitive to temperal activity and can be used to detect spikes in rift anomolies that can be dangerous if left unattended.
