– A depressed Jennifer to Carl Nesmith.[1]

Jennifer Nocturne is a movie actress from Ben 10: Ultimate Alien. She was introduced in Hero Time, and briefly served as a new love interest for Ben and a potential rival for Julie.


In Hero Time, Jennifer had long blond hair. Her wardrobe changed gradually. She wore a violet dress with a black sash, a red dress, and then a black shirt with a purple jacket and white shorts with black heels.

In Catch a Falling Star, Jennifer cut her hair and dyed it black in a similar style as Julie Yamamoto and wore the same purple jacket, black shirt with blue pants.

In Omniverse, Jennifer's hair has returned to its blonde and long form. She wears a purple cutaway dress shirt with black at the center. In addition, she dons silver ring bracelets and a crescent moon necklace.


Jennifer was a very happy, friendly and cheerful young actress. She was a big fan of Ben, and didn't resist kissing him when he rescued her from some thugs. When Ben won the contest between him and Carl Nesmith (as Captain Nemesis), Jennifer was enthusiastic. Because of her youth, Jennifer showed great fear when she was kidnapped by Nemesis and stayed close to Kevin during the fight between him and Ben.

Jennifer began to suffer from Stockholm syndrome after freeing Nemesis from prison, and thus became as violent and cruel as he was during her time with him. Jennifer was so unstable that she felt no remorse for the innocent people that Nemesis murdered, and didn't seem to mind watching him kill them either, nor did she try to stop him once.

Although her fondness of Ben had vanished as she did not resist shooting down Clockwork with Nemesis' laser glove, she briefly hesitated killing Eatle with Nemesis' mech suit after brutally defeating him.

A few of the partial reasons of Jennifer's persona change are of her past: her mother living in a trailer, never knowing her father, and having "behavioral problems" resulting in her having to quit one of her movies. These factors collectively have made Jennifer a "train wreck".[2][1]

By Omniverse, Jennifer appears to has recovered from her mental problems and is pursuing acting once more.[3]



Jennifer ran away from her mom when she was only fourteen and joined a TV-contest. According to her mother, Jennifer has never returned home. Later, Jennifer became a famous actress.

Ultimate Alien

Jennifer was first mentioned by a reporter in Hit 'Em Where They Live.

Jennifer kissing Ben after he rescued her

Jennifer was introduced in Hero Time, as a rich and famous teenage actress playing in a vampire movie named "Darkfall" (a parody of the real-life best-selling novel Twilight). As she visited Bellwood, she was the target of a faked kidnapping attempt organized by Captain Nemesis in order to save her and raise his image in the media. After Ben interfered and stopped the kidnapping instead of Nemesis, Jennifer revealed herself to be a big fan of him and kissed him on the lips in public. This was immediately called "the romance of the century" by the media, and Ben agreed to pass time with Jennifer, as according to her agent, this would be great for publicity.

This event quickly caused Julie to become jealous, despite Ben's insistence on the fact that him and Jennifer were "just friends" and he and her were not dating. Julie's jealousy grew worse when Jennifer invited Ben at Captain Nemesis's party and came to take him in a golden helicopter.

During the hero contest between Captain Nemesis and Ben, Jennifer was taken by Will Harangue as a guest correspondent to supervise the competition.

Later, in an attempt to get his revenge on Ben, Captain Nemesis changed his name to Overlord, intercepted Jennifer's helicopter and kidnapped her. When Overlord forced Ben to rescue only Jennifer or Julie, Ben saved Julie as Goop, while Kevin and Gwen saved Jennifer. After Overlord was defeated by Water Hazard, Jennifer attempted to flirt with Kevin, but was quickly stopped by Gwen who threatened to "peel her like a grape".

Jennifer after cutting and dyeing her hair

In Catch a Falling Star, Jennifer has gone to see Nemesis (now going by Carl) almost every day ever since he went to jail and helped him escape from prison. During her time with Carl, Jennifer had developed Stockholm syndrome (a condition in which victims sympathize with people who kidnapped them). She and Carl ran away together and changed their appearances, she simply shortened her hair and dyed it black, while Carl received plastic surgery on his face. Jennifer dreamed of starting a new life with Carl and living happily together, while he wanted to get revenge on Ben Tennyson. She helped him break into his company's (Nemesis Corp) building and activated a large robotic suit with which Carl intended to destroy Ben. While it seemed that he was simply using her to get his revenge, Carl actually did care about Jennifer, as he took entire responsibility for his escape and actions so that she could remain free and outside of jail and able to get back together with him once he was let out.


Before her reappearance, Jennifer was occasionally mentioned by Rook throughout the series, either when he referenced a movie or Ben's love life. An example of this occured in Fight at the Museum, when Ester listed some of Ben's previous love interests.

Jennifer Nocturne appeared as one of the many contestants vying for Ben's hand in marriage in The Most Dangerous Game Show. Her hair is back to being blonde. She fails the first round when she cannot keep quiet in Hex's library, reading the title for a critical review of a movie she starred in aloud in horror. When Hex shushes her, she shushes him right back before she is poofed out of the game.

  • Jennifer Nocturne is notable for her voice actor Tara Platt, who is married to Yuri Lowenthal (Teenage Ben's voice actor in the Classic Timeline).
    • Her character design when she changes her hair to black even resembles Platt's appearance in real life.
  • Prior to her persona change, Jennifer was the "down to earth" type and preferred to travel by helicopter rather than in a limo, the latter being used "just for show".[4]
  • When asked why Jennifer abandoned her mother and never visited her, Matt Wayne admitted that she needed mental help.[MW 1]
