The 456
The 456 (as referred to by the Human race) where a race of aliens who invaded the Earth twice: once in 1965 and once again in 2009.
Biology and Anatomy
They are an race that live in an environment which is poisonous to the human nervous system, with it being a compound of various well known chemicals such as cyanide and fluoride.
The natural design of their body consists of three heads, connected to one body via three long necks. They have the ability to emit a viscous yellow fluid in moments of high frustration. They use children as intoxicants or drugs, the children's bodies produced certain chemicals that stimulate feelings of pleasure in the 456. It is supposed that they deliberately mutilate thier bodies to attain this pleasure and their natural design does not involve having another being hard wired into them. During the process the child is feels no pain and lives long beyond its years however it is concious and has to breath air through a respirator. � (TW: Day Three, Day Four, Day Five)
Technology
The 456 were known to have technological systems which could meet the systems of the human race from 1965 onwards, such as radio telecommunications, and some chemical knowledge compatible to those of human standards.
They also where far more advanced than the human race they had the chemical and biological knowledge to provide a range of viruses and anti-viruses. They could wire a human child into their own life-support systems, thus living off it, transport themselves across space and through matter with little effort in what could have been described as a "great pillar of fire", while still remaining hidden from advanced radar and satellites.
They could also manipulate the minds of millions of people at will, as displayed when they came to Earth in 2009, when they forced all children globally on Earth to chant "We are coming" for a matter of seconds, this carried on more frequently, 'til it got so sophisticated that they had each country's children relaying a different message to their own governments.

History
First contact was made by the 456 in 1965 when a new strain of Indonesian flu was projected to kill millions and there were difficulties in coming up with an anti-virus. Then, speaking through radio waves on the signature frequency, 456 came alien voices, they claimed to have an anti-virus to cure this and that they were prepared to trade the anti-virus for twelve children, and a promise never to return to Earth. The UK Government did agreed to do so. (TW: Day Four)
The 456 gave the government a meeting point in the Scottish Highlands. Captain Jack Harkness drove a bus containing twelve orphan children to the location. The 456 said that the children would not be harmed, and in fact "would live forever." Harkness and armed personnel ushered the children into a great radiant light, and with the exception of one orphan, the 456 took the children and vanished, transmitting the information needed to create the vaccine. (TW: Day Four)
In September 2009, the 456 returned to Earth. Thus not keeping to their promise. They first stopped every single child on the planet and used them to convey the message "We are coming." (TW: Day One)
They followed up by secretly using the radio frequency 456 to relay instructions for a purpose built gas-filled chamber to be constructed for them on the top floor of Thames House. (TW: Day Two)
On their arrival day they came through the sky in a pillar of fire into the chamber, and began negotiations with John Frobisher, this time asking for 10% of the world's children in exchange for not destroying the human race. (TW: Day Three)
The request was denied and the UK government offered 6200 children; the 456 rejected this offer and used the children of each country to tell the prospective governments the number of children required by the 456. The arrival of Jack Harkness led to an argument with the 456, who then released a poison compound into the air of Thames House as a a demonstration of what the people of Earth would receive if they didn't comply. This killed every one in Thames House including Ianto Jones and Jack Harkness. then gave the governments of the world one day to consider. (TW: Day Four)
The government thus continued with its operations to round up 10% of the UK's children and hand them over to the 456. Fortunately before the 456 could take their prize Jack Harkness was able to reverse the signal they had used to control the children and turn it back on them which killed them thus saving the Earth at the cost of Harkness' own grandson (TW: Day Five)
