Ben Tennyson, now in his twenties, must confront a formidable foe named Null—a former bounty hunter who seeks to steal the powerful Omnitrix and bend time itself to forge an unstoppable army. 

SYNOPSIS:

Years have passed since Ben Tennyson first donned the Omnitrix as a young hero. Now in his early twenties, Ben is navigating the challenges of young adulthood while still balancing his responsibilities as a hero. The alien technology has evolved, and so has Ben, who has not only grown stronger but also wiser in his understanding of what it means to be a hero. When a powerful new villain, known as Null, emerges from the shadows, threatening to harness the Omnitrix for his own sinister purposes. Null, a former intergalactic bounty hunter, possesses unique abilities that allow him to manipulate energy and even bend time, making him a formidable opponent. As Null begins to capture former enemies of Ben, he aims to create an army that could overpower him. To combat this new threat, Ben must reconnect with his old allies, including Gwen and Kevin, who are now adults pursuing their own paths.
