Abzorbaloff

The "Abzorbaloff" was a Clomian who disguised himself as a Human under the alias Victor Kennedy. He could absorb his victims bodies, along with their memories and consciousness, into himself.

Origins
Clom, the creature's home planet, was the sister planet of Raxacoricofallapatorius. Despite a passing resemblance to them, he spoke of the Raxacoricofallapatorians with contempt. (DW: Love & Monsters) Jack Harkness implied that Clomians were distant cousins of the Slitheen, from a family known as the "Abzorbalovian Rebels". (WEB: Captain Jack's Monster Files)

LINDA
Circa 2007, the "Abzorbaloff" lived the lifestyle of a wealthy Human gentleman named Victor Kennedy. When he discovered the Doctor's picture on LINDA's website, (TS: Tardisode 10) Victor recruited them to try to locate the Doctor with the aid of Torchwood files that he had somehow obtained.

Feigning a common interest in this mystery figure, he picked off members of LINDA one by one until he could acquire his real quarry. He planned to absorb the Doctor's memories and knowledge. He was defeated when the remnants of the absorbed members of LINDA rallied together to pull him apart from the inside. When Elton Pope then broke the cane, his limitation field inside it was destroyed. This caused his absorption ability to go out of control, and his body to collapse into a gooey puddle. The remnants then seeped into the ground. (DW: Love & Monsters)

Abilities
The physical absorption process was begun by a simple touch and was irreversible. The faces of his victims could be seen embedded in his flesh and retain their identity and consciousness for several days at least, but were also able to access the creature's own thoughts. Even after that time, remains of their faces could still be visible. Victor also required the use of a limitation field, disguised as part of Kennedy's cane or the cane itself, to keep his absorption ability in check. It would also seem that Victor possessed some kind of ability or technology that allowed him to change his appearance (possibly a shimmer) as he was able to take on the form of Victor Kennedy.

Behind the scenes

 * The 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 monster for Doctor Who. The on-screen Abzorbaloff remained mostly faithful to the drawing with a few changes. The drawing depicted the Abzorbaloff as about the size of a building, rather than Human-sized that it was depicted as in the episode.
 * Dean Harris played Victor Kennedy in Tardisode 10, only his hands were shown.
