Weevil

The Weevils were a race of savage alien humanoids found in Cardiff, due to the Cardiff Rift.

Biology


Weevils were roughly humanoid in shape and size, but were a bit taller and had flattened faces with many sharp, fang-like teeth. Though faster and stronger than Humans, they were not extraordinarily powerful and could be injured with electricity, brute force or by Torchwood's anti-Weevil spray—though they began to develop a resistance to the spray. (TW: Combat)

Though not quite cold-blooded, Weevils had a much lower body temperature than Humans. (TWN: Slow Decay) Weevils had an advanced digestive system, allowing them to eat almost anything, though they preferred meat. (TW: Everything Changes, TWN: Slow Decay) They had powerful teeth and killed by biting and ripping at the throat and body. (TW: Countrycide) Their digestive system was connected to their circulatory system, meaning that anything that got in it (be it bacteria or bullets) would eventually be digested. (TWN: Slow Decay) The Pharm was able to extract a pesticide and a powerful defoliant from the Weevils. (TW: Reset)

Abilities
Weevils had mild telepathic abilities and could feel strong emotions from other Weevils far away. (TW: Combat, TWN: Slow Decay) They were also believed to have a degree of time sensitivity (TW: End of Days);the ability to detect the illusions created by Bilis Manger (TW: End of Days); were afraid of the sleeper agents (TW: Sleeper); and followed Owen Harper after he was brought back by the Resurrection gauntlet. (TW: Dead Man Walking)

Weevils were incapable of swimming. (BBCR: Lost Souls)

Culture
Despite their violent actions, Weevils were at least partly intelligent. They wore clothing, had a basic social order and mourned the pain and loss of other Weevils. (TW: Combat, TWN: Slow Decay) When they first arrived from the rift they wore "half-clothing", but inevitably acquired human-made suits and garments. (TWN: Another Life) They also treated their dead with respect and were not cannibals. (TWN: Slow Decay) Despite this, they were unable or unwilling to communicate with Humans. (TW: Everything Changes)

The Weevils worshipped the Durac, the Resurrection gauntlet that created it, and Owen Harper after he was brought back by the gauntlet. (TW: Dead Man Walking)

Origins
The Torchwood Institute did not know the native time period and/or homeworld of the Weevils. An uninformed layperson, Mark Lynch, believed that the Weevils may be descended from Humans at a point in the future when "all that is left is rage". (TW: Combat) However, early Torchwood Research indicated they weren't derived from any native Earth species. (WEB: torchwood.org.uk)

Early Interactions with Humans
The Weevils had been arriving on Earth for over a thousand years, and Torchwood 3 believed they had been seen in the such places as the sewers of 4th century Byzantium and 1930s New York. The Torchwood Institute had known about them since the 1950s. (WEB: torchwood.org.uk)


 * It is likelier that the 1930s New York infestation was actually that of Pig Slaves created by the Daleks. (DW: Daleks in Manhattan/Evolution of the Daleks)

In 1497, via a Resurrection gauntlet, a powerful being, Durac, identified with and embodying death itself, entered the Universe. The Weevils worshipped it. Humans associated Weevils with death and in, woodcuts, illustrated a Weevil with the traditional cowl and scythe of the Grim Reaper. (TW: Dead Man Walking)

21st Century
The Weevils had been more commonly seen in 21st century Cardiff, where hundreds lived in the sewers. They generally ate the most common resource in the sewers, though they occasionally ventured out to feed on Humans. (TW: Everything Changes) Others lived in the the church of St. Mary's, where they had collected a wide range of Human artifacts. (TW: Dead Man Walking)

One of the jobs of the Torchwood 3 was to capture these Weevils and put them in storage cells in the lower level of the Hub. Several cages were kept for storing these rogue Weevils and anti-Weevil spray and handcuffs are stored for this purpose. (TW: Everything Changes) As such, many missions of Torchwood were started while hunting Weevils. (TW: Reset, BBCR: Lost Souls)

During the flooding from a Bruydac ship, many Weevils were forced aboveground, including one which Jack Harkness accidentally hit and killed with the Torchwood SUV. Following the Bruydac incident, Torchwood was forced to track down the displaced Weevils. (TWN: Another Life)

When Doctor Scotus started distributing alien tapeworms, they made the patients so ravenously hungry that they would kill and eat Weevils. The Weevils started to fear these infected people. (TWN: Slow Decay) Some Weevils were captured by Mark Lynch for his "Weevil Fight Club", where Humans battled against Weevils to deal with their pent-up rage; one of the Weevils captured was Torchwood's Janet, who was subsequently recovered. (TW: Combat)

When the Cardiff rift fractured, more Weevils than ever appeared on the streets, making Torchwood 3's task of rounding them up even more difficult. (TW: End of Days)


 * When the fractures sealed up and the other temporal refugees returned home, we do not know if the new Weevils vanished as well.

Unknown to Torchwood 3, the Pharm had also captured at least one Weevil as part of their self-assigned mission to exploit the unique qualities of alien species for use in biomedical research. As noted above, the Pharm discovered the Weevils useful as far as developing new kinds of defoliant and pesticide. (TW: Reset)

After Owen Harper was killed at the Pharm, Jack Harkness went to the church of St. Mary's and stole a Resurrection gauntlet from the Weevils. When Durac returned and possessed the undead Owen Harper, Weevils followed him.(TW: Dead Man Walking)

The Vandrogonite Visualiser that was dug up in Rhiwbina had records of the Weevils. When Gareth Portland created MonstaQuest, he used the Weevil as one of the characters, renaming it "Toothsome". Since Toothsome was a common character, Weevils were frequently created, leading to an outbreak of Weevil attacks. (TWN: Pack Animals)

On another occasion, Torchwood was chasing a rogue Weevil through Cardiff when Jack was contacted by Martha Jones on the disappearances at the Large Hadron Collider. In the mean time, the Weevil was accidentally chased into the river, where it drowned. (BBCR: Lost Souls)
