The Sensors are dispatched to Wakanda by the High Evolutionary during the Evolutionary War.
Wakanda holds the world's only source of Vibranium, which the High Evolutionary needed, so he sent the a team of armored lackeys to attain it but they were stopped by the [[Black Panther:char:1477], Wakanda's king. The Black Panther noticed a secret note on one of the armored lackeys that told him to contact the Avengers West Coast, who came to his aid. Shortly after the Avengers West Coast arrived, the Sensors showed up. They fought against the combined might of the Avengers West Coast and the Black Panther, and were used mainly as a distraction while another lackey of the High Evolutionary was able to steal some vibranium.
