Julie Yamamoto-Tennyson

**Julie Yamamoto-Tennyson** is Ben 10's ex-girlfriend and now Step-mother. She first appeared in *Ben 10 Returns: Part 1* at Ben 10's soccer game to congratulate him on his game-winning goalie work. She later broke up with Ben 10 some time between *The Ultimate Enemy: Part 2* and *A fallen angel*.

She is also the mother of Carl Tennyson Jr.

## Appearance

Julie has black hair, brown eyes and wears a black T-shirt, mostly hidden under a pink hooded jacket and a white mini skirt. When playing tennis, she wears white wristbands, a white T-shirt, and her skirt. She has short black hair and sports white tennis shoes.

In *Inspector 13*, she is wearing a light blue vest with a dark blue skirt, black leggings, blue socks and her usual shoes.

## Powers and Abilities

Being an ordinary human, Julie doesn't possess any superpowers herself, although she's quite good at tennis and shows some fighting ability in *Pet Project* where she takes one of the Forever Knight's electric maces and easily knocks out several Forever Knights with them (one of these knights being comically unintentional while she replied to Gwen's acknowledgment). Julie is the only one who can fully command Ship, making her a competent ally.

In *Vreedle, Vreedle*, Ship reveals that he can "merge" with Julie. When Ship enveloped her, he became an armored battle suit. In the suit, she demonstrates enhanced strength and great damage resistance, as well as the ability to fire powerful lasers.

In *Eye of the Beholder*, it turns out that Julie can understand Ship's language.

## History

### Alien Force

Julie first appears in *Ben 10 Returns: Part 1,* where she congratulates Ben 10 after his team won a soccer game. She introduces herself and agrees to meet him at school the next day.

In *Pier Pressure*, Ben 10 asked Julie out on a date. It was interrupted by Ship, who kidnapped Julie. During a rescue attempt, Julie found out about the Omnitrix, which she finds cool. In the end, it was revealed that Ship was trying to lead Ben 10 to Baz-El, whose ship crashed and was about to explode. Ben 10 and Julie helped fix Baz-El's ship and he left Ship with them, saying that he and Ben 10 have a bond. On the walk home, Ship takes off after a passing truck and Ben 10 and Julie walk home, holding hands.

In *Save the Last Dance*, when Big Chill takes control of Ben 10's personality and starts eating every metal object in sight, Julie follows him on her motor scooter and alerts Gwen Tennyson-Levin and Kevin 11. She also told them where Ben is headed. Gwen Tennyson-Levin and Kevin 11 manage to subdue Big Chill, only to discover that Big Chill was building a nest for eggs he had laid. The eggs hatch into baby Necrofriggians and Kevin 11 teases Ben 10 about being a "mommy". As Julie takes Ben 10 home on her motor scooter, she tells Ben 10 that she thought he made a great "mom". Ben 10 also stated that she gets straight A's.

In *Pet Project* it was revealed that Julie is keeping Ship as a pet; it put a strain on her relationship with Ben 10, as he feared Ship could do something that she couldn't handle. The Forever Knights kidnapped Ship, planning to use him to mass-produce spaceships to go to the Dragon's planet, brainwashing him. Julie managed to get through to Ship and bring him back to his senses. At the same time, she told Ben he wasn't the only one who saw *Brainstealers From Outer Space*; he skipped a date to watch a marathon of it. Julie would allow Ben 10 and the others to use Ship's new spaceship form if they asked her.

In *War of the Worlds: Part 1*, Julie helped Ben 10 fight against the Highbreed invasion and it turned out that she apparently had a curfew. She also seems to show a deal of concern and care for Ben 10. At the end of *War of the Worlds: Part 2*, Ben 10 and Julie get close to kissing, but decided against it, as Gwen Tennyson-Levin, Kevin 11 and Max Tennyson were all watching. Ben 10 then tells her that he will walk her to school the next day and Julie gets home by riding Ship after giving Ben a loving smile.

n *Vreedle, Vreedle*, the Vreedle Brothers, hired by Baz-El to return Ship to him. As Julie refused, the Vreedle Brothers started being more aggressive and Ben 10 and Kevin 11 go in court to claim their right on Ship against Baz-El, while Gwen stayed on Earth to keep Julie and Ship safe. When the Vreedle Brothers came back, Ship revealed he can "merge" with Julie, giving her a powerful battle suit she can use to fight back against the Vreedle Brothers. Ben 10 is eventually able to get the judge's favor and Baz-El reluctantly accepts that Ship is now Julie's.

In *Singlehanded*, Julie finds Ben 10's detached hand and takes it to Gwen Tennyson-Levin and Kevin 11. She later uses Diamondhead's hand to fight Sunder. During the fight, Gwen Tennyson-Levin helped her keep Ben 10's hand away from Sunder but Julie wound up being used in a trade when Sunder caught her. After Sunder was knocked out, she, under Kevin 10's instructions, held a beam on Ben 10's arm while they used Sunder's axe to put Ben 10 back in one piece and unknowingly sent Sunder to the Null Void as a result.

In the *The Final Battle: Part 1*, Julie is briefly seen playing with Ship.

### Ultimate Alien

In *Fame*, sixteen year old Julie comforted Ben 10 when his identity was revealed to the world. When he thought everybody would hate him, she kissed him on the cheek and told him that not everybody hated him.

In *Duped*, Julie becomes very upset with Ben 10 not spending time with her, as he chose to watch the movie version of "Sumo Slammers" as his real self while leaving an immature version of himself with her.

In *Hero Time*, Julie becomes jealous of Jennifer Nocturne after she kissed Ben 10 when he saved her life. Later, she was kidnapped by Overlord. When he tried to kill her and Jennifer, Goop saved Julie. Goop then called her "his girl", and she smiles. She then assisted in taking down Overlord.

In *Absolute Power: Part 2*, Julie and Ship help Gwen Tennyson-Levin escape Kevin 11. She later appeared in her battle suit for unknown reasons.

As shown in *Eye of the Beholder*, Julie and Ben 10 were going through relationship troubles. Ben 10 apologized to Julie for being such a jerk and he promised to try to be a better boyfriend, which makes them both happy.

In *Revenge of the Swarm*, when Ben 10 and Julie arranged a date, she was kidnapped by the Nanochips at the behest of Elena, who was jealous of her. When Armodrillo freed Julie, Elena used the swarm in an attempt to suffocate Armodrillo. Julie was able to convince Elena to stop her Nanochip activity if she really loves Ben 10, as well as Julie herself loves him. Then she watches Elena kill herself to stop the Nanochips and Ben 10's life is saved. As Ben 10 mourned Elena's supposed death, Julie gave him some comfort before they both drove home in Ben 10's car.

In *Greetings from Techadon*, Julie and Ben 10 competed in a golf course and Ben 10 won, thanks to Brainstorm, but Julie was shown not to be happy and accused Ben 10 of cheating in the death hole. At the end of the episode, Ben 10 said he must go and have a rematch as promised to Julie.

In *The Flame Keepers' Circle*, Julie joins a philanthropic organization called the Flame Keepers' Circle, as she accepts their theology of using Diagon's technology to advance Earth's humanitarian efforts and create a utopia. She tries to get Ben 10 and Kevin 11 to understand but fails, becoming quite angry at Ben 10 in for this as he laughed in the Cult Leader's face and he himself uses alien technology to protect Earth. She believed this to the point of pretending to be a hostage for Conduit Edwards to make Ben revert from Big Chill. She again tries to preach the benefits of the Flame Keepers' Circle to Ben 10, but realizes her mistake when Ben 10 tells her that it is Vilgax. She maintains a belief that alien technology should not be kept from humans although is far less fanatical.

In *The Perfect Girlfriend,* Julie went off to Europe for a tennis tournament, during that time Elena impersonated Julie to try and win Ben's heart. Right after Elena revealed herself, Julie arrived at Ben's home, and was able to talk Elena down again, prompting her to leave swearing revenge.

In *Night of the Living Nightmare*, in Albedo's nightmare, Julie and Ship attacked Ben 10.

In *The Ultimate Enemy: Part 1*, Julie was playing a game of tennis when humanity was turned into Esoterica. She was able escape the mass transformation when Ship merged with her.

In *The Ultimate Enemy: Part 2*, Julie showed up after Ben 10 stripped Vilgax of Diagon's powers and managed to talk him out of selfishly wiping out all evil. After Ben 10 turned all of humanity back to normal, Julie kissed Ben on the lips for the first time in front of the others.

In The wedding (part 1), Julie gets married to Carl Tennyson.

In The strange day, Julie reveals (off-screen) that was pregnant and give birth to her son, Carl Tennyson Jr.
