Colonel Ross

Colonel Ross is an alternate-reality version of Thaddeus Ross and a part of President Kelly 's genocidal government intent on wiping out all mutants from the face of the planet.

As such he is a far more villainous individual than mainstream Thaddeus Ross, who tends to focus on Hulk and has not expressed genocidal feelings towards mutants as a whole.

This version of Thaddeus Ross is guilty of crimes on a scale equal (if not surpassing) those of mass-murderers during some of history's worst massacres and he was unrepentive, being the main man behind the Sentinels.

Colonel Ross was ultimately murdered by Hyperion, who snapped his neck.
