"Human Alliance" was a subbrand of the Dark of the Moon toyline. One of the figures in it was called Sergeant Cahnay, but as was (is) the style he wasn't given much in the way of biographical information.
In 2015, the facebook Ask Vector Prime feature said that this Sergeant Cahnay was the son of an unpleasant racecar driver and a flighty hotel heiress, alternate versions of Astoria and "Trans-Europe Express" character (and unlikable jerk) Auggie Cahnay.

Mercifully, Carlton Cahnay turned out like neither of them.
