Abzorbalovian

The Clomians were a race from the planet Clom.

External features
Clomians shared several features of Raxacoricofallapatorians such as yellowish-green skin, surprising speed, three fingers, three toes and a tail. Unlike Raxacoricofallapatorians Clomians were the size of an average Near-Human, they also had normal humanoid eye colours unlike the pure-black eyes of the Raxacoricofallapatorians, on some parts of their body they had several purpleish warts. They had pointed-ears and folds of skin on their cheeks. (DW: Love & Monsters)

It's unknown if Clominians are Calcium-based or what other features Clominians possibly share with Raxacoricofallapatorians such as hunting instinct or a highly developed sense of smell.etc

Technology
Clomians presumably used some sort of Spacecraft as the Abzorbaloff was able to travel to Earth. The Abzorbaloff used a limitation field to control his absorbption abilities, he also used some sort of technology to appear human. (DW: Love & Monsters)

The Technology could have been a Shimmer as the Abzorbaloff's human form appeared similar to his true form.

Culture
Some Clomians were Xenophobic and despised Raxacoricofallapatorians. (DW: Love & Monsters)

Clomians were quite an unpopular species, as when the Doctor found out Clom had been stolen he replied "Who'd want Clom". (DW: The Stolen Earth)

An expression of the frustration of Raxacoricofallapatorians was "Oh for the love of Clom". (SJA: Revenge of the Slitheen)

Land Prawna were a popular delicacy on Clom and was also enjoyed by Raxacoricofallapatorians. (SJA: The Gift)

Occasionly Clomians bred with Raxacoricofallapatorians as the Abzorbalovian Rebels were descendants of the Raxacoricofallapatorian families Chippeen Family and Fittereen Family.(WEB: Captain Jack's Monster Files)

History
The Clomians were part of the four-world Raxas Alliance along with the Raxacoricofallapatorians and the people of Raxacoricovarlonpatorius and Clix.(SJA: The Gift)

The Raxacoricofallapatorian Clom Colonists set up a colony on Clom. (WEB: Captain Jack's Monster Files)

The Abzorbalovian Rebels were a notorius Clomian criminal organisation descended from the Raxacoricofallapatorian Huspick Degenerate. (WEB: Captain Jack's Monster Files)

In early 2007 and Abzorbalovian Rebel came to Earth with the intention of finding the Doctor, absorbing him and gaining all his knowledge and experience and then taking his TARDIS. He tracked down LINDA and then went to their meeting place and offered to help them find the Doctor, he later took over the organisation, while LINDA worked to find the Doctor he absorbed some of them claiming they just left, however Ursula Blake and Elton Pope discovered his true intentions, he then absorbed Ursula and tried to absorb Elton however the Doctor and Rose Tyler came to find Elton, when he was about to absorb Elton the absorbed victims fought back and the Abzorbaloff died when Elton destroyed his limitation field.

In 2009, Clom was stolen by the Daleks along with many other planets and relocated into the Medusa Cascade as part of Davros's plan to detonate the Reality Bomb. However, this plan was stopped by the Doctor and the Children of Time, who sent Clom and the rest of the planets back to their right place. (DW: The Stolen Earth)

Abzorbalovians
A group of Clomians called the Abzorbalovian Rebels, through use of a Limitation Field gained the ability to absorb other individuals as food. The physical absorption process was begun by a simple touch and was irreversible. The faces of their victims could be seen embedded in their flesh and retain their identity and consciousness for several days at least, but are also able to access the creature's own thoughts. As previously noted, the limitation field (disguised as a cane) to keep the absorption ability in check. (WEB: Captain Jack's Monster Files) (DW: Love & Monsters)

It is unknown if all Clomians have Absorbption abilites or just the Abzorbalovian Rebels

Behind the scenes

 * Abzorbaloff2.jpg basic design for the Abzorbaloff, and its name, came from a drawing by then 9-year-old William Grantham, an entrant to a Blue Peter competition to design a Doctor Who. The on-screen Abzorbaloff was slightly changed as William Grantham originally intended it to be the size of a double-decker bus.
