Absorption

Absorption was the process by which the Abzorbaloff, an Abzorbalovian, ingested his victims. (TV: Love & Monsters)

Nature

Abzorbalovians had the ability to absorb life forms by touching them. Absorbed victims would retain their consciousness and appear as faces on an Abzorbalovian's flesh for several weeks at least. Positions ranged from the stomach, shoulders, waist, thighs, chest, back and even buttocks. Once fully digested, the faces of said victims, while clearly deceased, were still somewhat visible. Abzorbalovians could fart due to their digestion, similar to humans. When a being was absorbed, their knowledge and experiences were also absorbed, which apparently affected how they tasted.

Historians who had been allowed access to the "Monster Vaults" of the databanks in the Doctor's TARDIS claimed that Abzorbaloffs sought the thoughts and experiences of other lifeforms as their own thoughts and experiences were "profoundly dreary". Abzorbaloffs liked to pride themselves on being gourmets. Their greed was so great that they often could not help blowing their cover by absorbing too many victims, which was identified as a major weakness.

As the Abzorbaloffs were constantly drawing sustenance through their skin, they naturally wore little more than a thong, sharing a predilection towards needing to be naked with the Slitheen family of Raxacoricofallapatorius. However, as the Abzorbaloffs absorbed other creatures into their body, the Slitheen tactic of hiding inside other creatures was beneath contempt. (PROSE: The Monster Vault)

History

In 2007, the Abzorbaloff, disguised as a human named "Victor Kennedy", absorbed his secretary after finding LINDA's website in his office. (WC: Tardisode 10, PROSE: The Time Traveller's Almanac)

Appearing at LINDA's base on Maccateer Street, Victor joined the group and absorbed Bliss after asking her for a word in private; her face ended up embedded into his posterior at the right buttock, leaving her subject to him farting on her and leaving her barely able to breathe or speak. Some weeks later, Victor used the same ploy to absorb Bridget Sinclair, whose face ended up on his right shoulder.

At least one week later, Victor absorbed Colin Skinner after convincing him to remain to track down Bridget with him as Ursula Blake and Elton Pope left the group; his face ended up in the left side of the Abzorbaloff's lower abdomen. When Ursula and Elton returned, they discovered the Abzorbaloff, who revealed his absorption abilities and his victims. By threatening to absorb Jackie Tyler to get to the Doctor he tricked Ursula into being absorbed and went to absorb Elton as well. The absorbed LINDA members were encouraged by the Tenth Doctor to fight back and pull at the Abzorbaloff's stomach. Elton then broke his limitation field, causing his absorption abilities to go out of control and melt him into the Earth. His absorbed victims, except Ursula, died with him. The Doctor had his sonic screwdriver to key into the absorption matrix and separate Ursula from his remains. Though, as the Doctor noted, it was too late for total reconstruction, Ursula was salvaged as a face embedded in a slab of concrete. (TV: Love & Monsters)

The Abzorbaloff was survived by his father who, in 2009, confronted the Doctor. Having already absorbed three human victims, it was this Abzorbaloff's intention to "guzzle up [his] smushed up remains" after leaving him to the Krakanord, after which he would absorb "every little meatbag" on Earth, only to be melted by the Krakanord.
