Twelve is one of
many prototypes for a new line of fabricated mutants that can't be permanently
harmed and has no memory. It was entered into the tournament to try it's
effectiveness. Twelve is the ultimate result of Gill's
"G-Project," a biological warfare operation overseen by Dr. Kure and Urien
after the completion
of Necro. It appears Twelve considers
Urien to be his father.
Eleven is an earlier prototype of Twelve.
A mimetic genetic creation, Twelve is able to assume the
forms of other people and change the shape of any part of his body to fit the
task at hand. Twelve was also supposed to exterminate Necro,
but that didn't happen. For some reason, Twelve is only capable of expressing
himself in a binary code cypher (00001 = A, 00010 = B, etc).
