Even by modern standards, the first of the SENTINEL robots to roll off the production lines were engineering marvels, masterpieces of deadly technology. With computational power superior to even the most advanced supercomputer and weaponry the equal of any on the planet, they could have done immeasurable good.
Instead, the creation of the SENTINEL robots was the opening of Pandora’s box that has wreaked untold destruction around the world. Though the X-Men and others wiped out the first generation of killer machines, the technology was out there, and evil, hateful men would stop at nothing to use it. Generation after generation of mutant-hunting robots followed – each one boasting improved energy weapons and ever more sophisticated mutant detecting software. Each generation learned from the defeat of the last, rendering every battle against a SENTINEL more dangerous than the last.
