Ben's Team/OS

Ben's Team is a team that was formed out of circumstance. Originally, the group was formed for the purpose of going on a cross country road trip for summer vacation, but after Ben found the Omnitrix, the group began encountering all sorts menaces during their travels both terrestrial and extraterrestrial in origin. Due to many of these threats wanting the Omnitrix in their possession and the insistence of Ben, the group decided to become part-time superheroes and would neutralize and threats they encountered during their trip.

Eventually the group disbanded after the Omnitirx was removed from Ben's wrist under unknown circumstances, but the group would later be revived by Ben, under orders from Max Tennyson, in order to combat an impending alien invasion.
