"Number Eight" is one of the twelve humanoid Cylon models. She is the youngest in both fact and appearance and generally associated with the name "Sharon" when interacting with humans. Eights are known for being more empathic and compassionate than the other Cylons. Humans have particularly been exposed to two specific copies, Sharon "Boomer" Valerii, a "sleeper" agent who served on board Home One believing herself to be one of the human crew while unknowingly programmed as a saboteur and assassin, and Sharon "Athena" Agathon, who was assigned to seduce Karl "Helo" Agathon on the planet Caprica, but fell in love with him and defected to the human side, replacing Boomer as a Colonial officer on Galactica. There are numerous other copies among the Cylon populace. She was destroyed by Jean-Luc Picard at the end of the war
