As Ben and Eunice are walking, they seem to be followed. Eunice is attacked by a bear and Ben becomes Armodrillo to save her. However, it seems that Eunice seemed to have calm the bear like all the other animals that surrounded her. Suddenly, when Ben was not looking, Eunice flashed green near the bear and with incredible super strength she pushes a boulder. Meanwhile, Sunder is at Eunice's ship, angered about what was missing. However, he sees the tire tracks from Ben and Kevin's cars, and looks pleased.

Ben and Eunice continue walking in the woods, and their crushes on each other grow as they were about to kiss until Sunder attacks them. Ben transforms into Spidermonkey and then later becomes Ultimate Spidermonkey to show Sunder his new bag of tricks. It is revealed that Sunder is after Eunice, and then Eunice strangely escapes by hopping high like a rabbit. Ben comes back to Gwen and Kevin, and Gwen is able to track Eunice because Eunice was wearing her spare clothes. They track Eunice to a mountain high up and Sunder finds them all again. Ben becomes NRG to fight Sunder, but Sunder manages to defeat him, Gwen, and Kevin, and begins telling Eunice that he can help her. However, Sunder presses a button on the back of Eunice's neck, which turns her into an Omnitrix core.

Ben begins to chase after Sunder as Cannonbolt and then becomes Ultimate Cannonbolt to rid himself of the obstacles near him. Ben and Sunder begin to fight as Ben wants to hurt Sunder for what he did to Eunice. But Sunder uses a device that makes Ben dizzy in order to be defeated. Gwen and Kevin arrive to help, and they manage to defeat Sunder and retrieve the Eunice Omnitrix core. After pressing a button, they turn Eunice back to her normal self. Eunice receives the agility of a snake and starts beating Sunder up, demanding to know who she is. Suddenly, Azmuth arrives and reveals he hired Sunder and that Eunice is the Unitrix, a prototype of the Omnitrix that could store the DNA of each species contained in both Omnitrix and Ultimatrix. It is revealed that Eunice got her human form from Gwen when she touched her ship. Azmuth, under Ben's orders, has Eunice to have a free life and to be one of his assistants as azmuth needs a helping hand on taking care of primus.
