Ben 10 season 2 episode 6 : The Galactic Enforcers

When a pair of bounty hunters plan to use raw minerals from earth to build a devastatingly powerful bomb, Ben joins a group of alien super heroes, the Galactic Enforcers, in order to stop them. However, all is not well with the new group, as a small gift of Ben's chocolate is all that's needed to weaken the group's leader, Ultimos. This causes his second, Synaptak, to take the lead in order to try showing Ben up. However, the Enforcers tactics involving 'commanding presence' backfire on them, and nearly getting Tini hurt in the process. However, after Ben goades Synaptak into rescuing Tini from a landslide, Ben and the Enforcers put aside their differences to finally arrest the bounty hunters.
