Passameer-Day Slitheen

The Passameer-Day Slitheen were a branch of the Raxacoricofallapatorian criminal family Slitheen.

21st century
The Passameer-Day Slitheen, like the rest of their family, were from Raxacoricofallapatorius originally. After the Slitheen bribed their way into government, their rule crashed the planet's economy and eventually the population rose up against them. (SJA: The Gift) Exposed, shamed, and arrested en masse in the Great Purge of Yon:556, the entire family was tried and found guilty, in perpetuity and given the death sentence with no chance of appeal. Many of the Slitheen fled justice, but the family continued to be hunted down by the Blathereen and Judoon. (SJA: Revenge of the Slitheen) In March 2006 the Passameer-Day Slitheen disguised themselves as various humans holding leadership positions and attempted to seize control of the UK government in an effort to start a nuclear war, they crashed their spacecraft into the thames to hoax an alien invasion to make the UN give them the codes to nuclear weapons. They also had a bigger ship in orbit above the North Sea. Their ultimate aim was to turn the Earth into a huge nuclear reactor pile and sell its remains off as starship fuel. This attempt was foiled by the Ninth Doctor and his allies. All of them, apart from Blon Fel-Fotch Passameer-Day Slitheen were killed when 10 Downing Street was destroyed by a missile. (DW: Aliens of London/World War Three)

Later the same year, in September, Blon, the last surviving member, managed to get herself elected as Mayor of Cardiff, and tried to abuse her position to attempt to blow up Earth by destroying a local nuclear reactor. The Cardiff Space-Time Rift would amplify the explosion where it would not only destroy Earth but enable her to escape the planet. This effort was also foiled by the Doctor and his allies. Blon was then regressed back into an egg by the heart of TARDIS so she could have a second chance at life. The Doctor then returned the egg to Raxacoricofallapatorius and gave it to a family who adopted her. (DW: Boom Town)

Despite this, the Passameer-Day Slitheen survived. In the year 5000000000, a Slitheen child called Klov Dreb Fotch Passameer Day Slitheen III stowawayed aboard the Doctor's TARDIS looking for adventure. He stole Cheese Sandwiches, Chips and Chocolate Biscuits in the Tardis for three weeks. The Moxx of Balhoon alerted the Tenth Doctor and Martha Jones that the Slitheen accused the Doctor of abducting their child. He tracked Klov to the Tardis, hiding under a floor panel in the console room. The Doctor took him back to his home, but not before stopping by the planet Morbel, an ocean planet with the biggest log flume in the galaxy. (WC: Who Ate All the Biscuits?)

As the Slitheen made a criminal accusation against the Doctor, it is likely that by the year 500000000 the Slitheen are no longer a criminal family.

Legacy
The attempt of the Passameer-Day Slitheen to reduce the Earth to molten slag and then sell it would prove to be an important moment in the history of the Slitheen family; it was a crushing failure to become rich and several attempts were made to make profit on Earth again, but none of them succeeded. (SJA: Revenge of the Slitheen,The Lost Boy,From Raxacoricofallapatorius with Love,The Gift). These failures played a vital role in the downfall of the Slitheen and place in the shadow of their successful cousins and enemies the Blathereen family. (NSA: The Monsters Inside)
