Alyssa Henry Matthews was born in Hunterville to a wealthy family with her brother Aaron. The two got into quite a few quarrels and played with their grandpa. At the age 12, the girl was saddened by the fate of their grandpa who died at the hands of the Nemesix. Azmuth was told of this by Grandpa Max; a reason he sent down not one, but two Omnitrixes.

The two would be given to them (despite their parents' pleas). The outdated Plumbers went to form a new group known as Generation Xeno, with a plan to bring together the most advanced tech they could find in their future. With just two Omnitrix users taking on all the evil Grandpa Max knew Generation Xeno had a chance.
