While on a camping trip in the wilderness, Ben, Gwen, and Kevin witness a spacecraft falling from the sky and crashing into a field, revealing a mysterious pod. Gwen touches the pod and causes it to open, revealing a beautiful, unclothed human girl. The girl, who calls herself Eunice, claims she has no memory of where she came from. Ben and Eunice become infatuated with each other, and when confronted by Gwen, Ben asserts that Julie broke up with him. Ben and Eunice grow closer, but they are suddenly attacked by the bounty hunter Sunder, who reveals that Eunice is in fact an Omnitrix-like device assuming a humanoid form. Sunder is then revealed to have been employed by Azmuth to retrieve Eunice, a.k.a. the Unitrix, a prototype Omnitrix. Eunice absorbed and randomized Gwen’s DNA to take on her current human form. Azmuth claims that Eunice is no more real than Ben’s transformations, but Ben threatens to fight Azmuth, prompting Azmuth to reluctantly recruit Eunice to aid him in work on Primus.
