The Perfect Girlfriend

The Perfect Girlfriend is the thirty eight episode of Ben 10: Ultimate Alien and the sixth episode in the third season.

Plot
Ben and Gwen are driving Julie to the airport so she can go to her next international tennis match. However, Ben's car picks up a police report about Ssserpent holding a person hostage. After an argument, Ben decides to go after Ssserpent while Gwen helps Julie at the airport. At a warehouse where Ssserpent is hiding, Ben transforms into Goop, but his anti-gravity projector is let out, turning his body into an immovable blob. It turns out Ssserpent planned this from the beginning and traps Ben in a large blender-like device, planning to separate him into multiple compounds.

Julie soon shows up when she is strangely supposed to be at the airport and distracts Ssserpent long enough to get the police inside and chase Ssserpent out. She then saves Ben and explains that she thinks their relationship is more important than a tennis match. However, she acts strange, as she lets Ben stay home to watch Sumo Slammers while she, Gwen and Kevin go shopping. Even Ship acts strange around her, growling and hissing at her in her presence. At the mall, Gwen questions Julie about her descions when suddenly she falls down the elevator shaft. She survives, but injures her left ankle. Ben, wondering why Gwen would fall down an empty elevator shaft, goes with Julie back to the mall to investigate. When the mechanic leaves, Ben transforms into Spidermonkey to check it out, but accidentally activates the elevator.

However, before the elevator could crush Ben, the elevator seemingly stops (you can briefly see Julie's eyes glowing, indicating she stopped it). Afterwards, Julie and Ben go the movies where they watch the new Sumo Slammers movie.Gwen, curious about Julie's behavior, asks Kevin to go spy on them. After the movie, Ben leaves again to look for Sserpent and Kevin follows Julie to Industry Boulevard, but suddenly, he is attacked by an animated building creature.

Ben sees that the Ssserpent sighting is a piece of his dead skin and soon gets a call from Gwen that Kevin is under attack. He shows up as Way Big and defeats the building creature. Ben then gets curious about Julie's behavior as well, with Kevin saying the monster showed up right before she disappeared. He goes to her house and meets her father, who says she isn't home. He finds her at his place and gets her to watch with him a tennis match on TV.

However, he finds it to be a replay of one of Julie's matches from yesterday. He finally recognizes the girl he is with to be an imposter and she reveals herself to be Elena. She explains that since Ben loves Julie, she masqueraded as her and tried to provide Ben everything he wanted to make him happy. Suddenly, the real Julie shows up so she could spend time with Ben, but then sees Elena. Angered, Elena transforms into her nanochip queen form while Ben turns into Echo Echo and then becomes Ultimate Echo Echo to fight Elena. She ends up defeating Ben by choking him with nanochips again, but then Julie drives her away by saying that if Elena can't have Ben, no one can. Elena then runs away into a sewer pipe, saying she now only feels hate and promising to return again.
