Gwen Tennyson (Ult. Timeline)

Gwen Tennyson is the daughter of Ben 10,000 ("Ultimate Ben") and Julie Tennyson. As well as the elder sister of Ken Tennyson. Temporarily kept secret, she is also the Chrono Spanner of her timeline. She is a human from the Earth of an alternate timeline.

Appearance
One could say that Gwen is rather identical to her mother at her age. Although she has her long, black hair kept in a ponytail. She has bright green eyes, clearly inherited from her father.

As far as casual clothing goes, she is frequently seen wearing a blue colored dress with white stripes on it's center. Accompanied by a pair of white, green striped tennis shoes.

As for her uniform as Chrono Spanner: Initially, it was the white armor atop a black jumpsuit. On her waist, is a utility belt with pouches and a circular device on the belt buckle. Crowning it is a white, horned helmet with a black visor, silver mouth-guard, and a green scarf below her neck.

After her identity was finally revealed to her family, she decided to go for a bit of a redesign for her uniform. Giving it a, quote-unquote, "feminine look". The white armor had been changed to pink, the horns had shortened, and she had ditched the green scarf.

On her left wrist, is a bright green bracelet, which is really her Spanner device in disguise. Undisguised, her changing device resembles a white and bright green square atop a white, metallic band wrapped around her wrist.

Personality
On the surface, Gwen could be seen as the "buzzkill" of the Tennyson. She is seen constantly bickering with Ken, almost mirroring her namesake relative. She appears to solely focus on her academics and athletics, and most of all, has no interest in heroics. Not even as far as an interest in the Plumbers. She claims that she rather be the "one normal relative for the family". Or so she claims.

On a more casual note, it turns out, Gwen is a "weeaboo". In her rooms, is a shelf containing Japanese media, ranging from manga to anime to her favorite, Super Sentai. Super Sentai seeming to be her favorite franchise, that she is constantly binge watching when she is relaxing for once. She notes to her brother, "You and Dad have Sumo Slammers, I have the Sentai."

And it seems that her love for Super Sentai inspired her behind the identity of '''Chrono Spanner. '''As Spanner, she acts kind of cold, rather stuck up when she is interacting with others. A kind of "We cross paths, but I work alone" manner. This turned out to be a cover, not wanting her interactions to affect her work. When she is doing missions, she is by the book and very detailed, no room for improvising nor error.

She is also very precautious, having various time capsules hidden in multiple eras, containing contingency plans. This is ever in case she is stranded in another time.

With all said and done, she does love her family, and worries for them when the heroics are concerned. It is why concerns herself with the time based missions that revolve around them. She loves them all, even if they do bicker a lot.

Powers and Abilities
More akin to her mother than her father, she does not have abilities related to the Omnitrix. She is rather extremely athletics, practicing in many sports, from mixed martial arts to tennis. She is shown to adapt a mundane object, i.e. a tennis racket or baseball bat, and use it as a melee weapon when provoked into combat. These combat skills are evident in her life as Spanner, but she is capable of mixing up her fighting style to hide her identity.

Similar to her Aunt Gwendolyn, she is extremely smart, skilled in her academics. It is noted that she pretty much has an A+ in all her classes. This though has nothing on the fact that she is seemingly an expert on all the time travel complications that occur for her work. As well as knowing how to fix her travel device if it were ever damaged.

It is occasional shown that Gwen has briefly studied the magic similar to her Aunt Gwendolyn and her father. This shown on her missions, casting a few spells, when in a tight spot. Although she is limited to a few spells, particularly the few she is constantly exposed to. i.e. "Contego", for force fields.

Weaknesses
As common throughout the Tennyson family, Gwen is primarily vulnerable when she without power or defense. If she is attacked when outside her Spanner equipment, she is likely to get hurt. Though she is athletic and trained in self defense, such can only do so much when against an empowered threat.

As she is constantly on time travel missions as Spanner, she is constantly skirting the line of her existence, as well as many when the future is concern. She is constantly having to ensure that every detail is at least partially the same when she is about to leave a time period. If one mission when to go south, she may be erased from existence.

A frequent element concerning her career as Spanner was to keep her identity a secret. But such wasn't easy when interacting with those who have enhanced senses and recognize her scent, i.e. Devlin Levin when mutated.

Biography
Gwen Sakurai Tennyson is the first born child of Ben and Julie Tennyson in the future. Growing up, she was well exposed to her father's heroics. From the career of Ben 10,000 to Ultimate Ben to even President of the United States. And for awhile, she felt kind of burnt out by all the extraordinary circumstances. Aliens, magic, mutants, etc. For a bit, she felt kind of burnt out and simply wanted to go for some normalcy in life. Then came her brother's 10th birthday, when he had received an Omnitrix. At first, she was unfazed. Then she picked up her father and brother's bonding. And she may have grown just a little envious...

Things only got more out of hand, when her family was indulging an alien battle, the building she was currently inside began to collapse. She was saved at the last second by an armored figure, known as Chrono Spanner. (This would later be revealed to be herself from the future.)

One day, she was met by Professor Paradox, who claimed he needed to act as an agent of his. Claiming that Cross time has gotten too big and plagued by too many issues for just himself. So he had equipped her with the gear of Chrono Spanner, enabling her the power to be a hero that would rival her family in many ways.

Thanks to the time travel nature of her work, she had partake in many missions throughout the timeline, with a few notable ones concerning her family. Such as the third Vilgaxian invasion, fighting along side her family. Another being that while her father was handling a mission involving Eon, she watched over Ken, protecting him from any of Eon's servants. It was during such that Devlin managed to connect the dots concerning her identity.

Following the confrontation between her and Devlin, she decided to reveal her identity to her family. Though their shock provided resistance, they decided that they couldn't keep her from continuing on with being a hero. Since then, she has public fought alongside her family.

Family
Ben Tennyson (father) - Although his extensive career of being a hero, Ben had made a loving relationship with his children, despite the occasional hiccup. The primary issue being that Ben bonds more with Ken due to the Omnitrix, but lately he has been making attempts to rectify that.

Julie Tennyson (mother) - As Ken has a bond with Ben, Gwen has a bond with Julie. Julie was actually encouraging of Gwen's initial vow for normalcy, being quite understanding. Even after the revelation of her being Spanner, Julie again showed understanding, constantly being surrounded by heroes.

Ken Tennyson (brother) - Akin with those before them, Ken and Gwen seem to bicker a lot. A sibling rivalry that held no bounds. Initially, Ken use of insults for her were related to lack of desire to be "in on the family business". Though this ceased after he discovered her secret identity as the Spanner of their timeline. Even though they bicker, the two do love each other and will go to great lengths to protect the other.

Friends
Devlin Levin (cousin) - Son of Kevin and Gwendolyn Levin, the best friend that Ken could ask for, and occasional a pain in Gwen's side. Gwen can get quite tired of the boys' shenanigans. But the most of an issue she ever got with Devlin was when he confronted her, stating he knew her secret. By this point, she went along with him and decided to reveal herself to her family.

Trivia

 * As obvious, her first name is named after her Aunt, Gwendolyn Tennyson.
