Ben's Team (Alien Force and Ultimate Alien)

Ben's Team is the team Ben forms after his grandfather, Max Tennyson mysteriously disappears. Without his grandfather's guidance, he assembles a team under his grandfather's last orders to him. This team assists Ben in his duties to defend Bellwood from hostile alien activities in extension of the Earth and other places.

The team eventually disbanded when Gwen had gone to study in college and Kevin went to live in the same town as her after he found a place there. Ben and Rook formed a new duo in its place.
