Ep 4. Save the Last Dance

Five years have passed since the events of the first Ben 10 series, and Ben Tennyson, now a teenager, continues to use the Omnitrix to transform into various alien forms in order to protect the world from various threats.

In episode 4 of season 2, titled "Save the Last Dance," Ben and his team – Kevin and Gwen – head to a high school dance, hoping for a night of relaxation and fun. However, things take a turn when they discover that one of Ben's old enemies, the DNAliens, is present at the dance as well. The DNAliens are a race of genetically modified aliens who strive to mutate and control other species, and they have been a recurring threat in the series.

To make matters worse, the DNAliens are after a specific student who happens to possess a rare and valuable gene that they seek to extract and use for their own purposes. Naturally, Ben and his team cannot stand by and let this happen, so they spring into action to protect the student and stop the DNAliens.

As they navigate the dance floor, Ben and his team are forced to assume their alien forms and engage in battle with the DNAliens, all while trying to avoid arousing suspicion among the other students. They soon realize that the DNAliens have a powerful ally on their side – a dangerous and elusive creature called the Forever Knight. The Forever Knight is a powerful warrior who seeks to uphold a strict code of chivalry and honor in his battles, but is willing to work with the DNAliens to achieve his own ends.

As the night wears on, the situation becomes increasingly dire. Ben and his team must work together to overcome the DNaliens and the Forever Knight, all while keeping the other students at the dance safe and unaware of the danger. Along the way, they will encounter unexpected allies, dangerous foes, and incredible new forms to help them in their quest.

Ultimately, "Save the Last Dance" is a thrilling and action-packed episode that highlights the exciting and adventurous spirit of Ben 10 Alien Force. It showcases the power of teamwork and the importance of standing up for what is right, even in the face of overwhelming odds.
