Huspick Degenerate

"The Family Slitheen is descended from the original Huspick Degenerate. The distinctly dodgy Slitheen are cousins to some equally unpleasant Raxacoricofallapatorian families."

Huspick Degenerate was the Raxacoricofallapatorian ancestor of the criminal clans of the Raxas Alliance.

Cultural Details
The Slitheen placed great importance to hunting, which included the hunting of sentient prey. (SJA: Revenge of the Slitheen) They sometimes displayed joy at triumph by disrobing. (DW: World War Three) Blon said that the Slitheen used venom grubs to dispose of family members not willing to engage in criminal activities (DW: Boom Town).A common tactic by the Slitheen to threaten their enemies in a confrontation is to grab one of them by the neck and threaten to kill them. (DW: Boom Town,SJA: The Lost Boy,The Gift)

Technology
Some Raxacoricofallapatorian families such as the Slitheen and the Blathereen developed a method of disguising themselves as other lifeforms by first obtaining the skin of a dead victim -- referred to as a skin suit -- and compressing themselves into it. In order for this to work the victim needed to be heavy set, and the compression had a side effect: a gas exchange occurs which causes the disguised Slitheen to frequently expel gas with a sound similar toflatulation. (DW: Aliens of London; SJA: Revenge of the Slitheen). In late 2008, the skin suit technology was improved to allow Slitheen to assume a greater variety of human body types, and the gas-exchange issue was eliminated. (SJA: The Lost Boy) It wasn't always initially used (SJA: From Raxacoricofallapatorius With Love; The Gift), but would remain the standard until at least 2501. (NSA: The Monsters Inside)


 * It is unclear whether the improved skin suits are artificially created, or if humans still need to be killed and their skins obtained.

The Abzorbalovian Rebels also used some sort of technology to disguise themselves. (DW: Love and Monsters)

This technology was possibly a Shimmer as the Abzorbaloff's true form resembled his human form

Raxacoricofallapatorian criminals used their peoples own spacecraft to aid their criminal activities as did the Abzorbalovian Rebels, they also stole or bought ships. (DW: Aliens of London,Love and Monsters,NSA: The Monsters Inside,SJA: The Gift)
