Convinced mutants posed an inevitable threat to humanity, anthropologist Dr. Bolivar Trask along with a small group of researchers hired a large team of cyberneticist, roboticist and engineers to develop and construct the robots known as Sentinels.

Trask publicly revealed his mutant hunting robots during a televised debate with leading mutant expert Professor Charles Xavier (Professor X). The Sentinels overcame their programming and rebelled against their human master, determining the only means to protect humanity from mutants would be to enslave them all.

The Sentinels were initially destroyed by the X-Men but the design and programming has been duplicated various times by different groups, and including Sentinels themselves, namely the Master Mold, Nimrod and Bastion.
