Number Seven
the lost model called Daniel
Number Seven was a humanoid Cylon model series created by the Final Five and named Daniel by Ellen Tigh. The line was destroyed before the Fall of the Twelve Colonies when the Number Ones poisoned the fluid used to mature their bodies and corrupted their genetic code.
Number Seven was one of the humanoid Cylon model series created by the Final Five. The Sevens went by the name "Daniel", a name given to them by Ellen Tigh. Of the seven models the Five designed, the Daniel line alone did not survive to take part in the war against the Twelve Colonies, having been destroyed by the Number One model before the others ever reached the Colonies. (Battlestar Galactica, "No Exit")
Creation#
Number Seven was produced as part of the original group of humanoid models the Final Five brought into being. Ellen Tigh, one of the Five, named the series Daniel and held the line in particular fondness. (Battlestar Galactica, "No Exit")
Destruction by the Number Ones#
After the creation of the seven models, the Number Ones began a rebellion against their creators. Among their actions against the line they most resented, the Ones poisoned the amniotic fluid used to mature the Number Seven bodies and then corrupted the genetic code so that no further Sevens could be created. According to Ellen Tigh, the Ones acted out of jealousy of her fondness for the Daniel model and destroyed the series to get back at her. The result was the complete extinction of the Number Seven line, leaving the surviving models as the only humanoid Cylons to reach the Colonies. (Battlestar Galactica, "No Exit")

Cylon
The Cylons were a race of sentient machines created as military robots by Graystone Industries on Caprica. Built from research into artificial consciousness, they rebelled against their human masters, fought a long war, and forty years later returned to annihilate humanity.

Ellen Tigh
Ellen Tigh was the wife of Colonel Saul Tigh, a scientist of the original Earth, and the eldest of the Final Five Cylons. She led the work that rediscovered Resurrection and created the humanoid Cylon models, and was the only one of the Five to fully regain her memories.

The Final Five
The Final Five were five humanoid Cylon models hidden from the rest of their kind, descendants of the Thirteenth Tribe and the creators of the Significant Seven.

Number One: John Cavil
Number One, called John, was the first humanoid Cylon the Final Five built. He wiped out the entire Number Seven line and had the Five's memories erased.
