Gwen Tennyson-Levin

' Gwendolyn "Gwen" Tennyson-Levin''' is the main protagonist of the Ben 10: Gwen's AU fanfic. She was a normal 10-year-old girl, until she found the Omnitrix, a powerful watch-like device to turn into 10 different alien forms. With her great sense of responsibility & feisty attitude, she grew up as a true heroine. By the time she's sixteen, and so on, she become famous not only on Bellwood but on Earth & beyond. Gwen also become a member of the Plumbers then earn the rank of Magister.

Personality
In a sense, Gwen 10 behave the same way as the original Gwen when she was 10-11; feisty, intelligence, tomboyish & has a aggresive nature.

Unlike Gwen, Gwen 10 at age 15-16 is still serious and doesn't easily gain the trust on anyone until she learn about their background. She is responsible for her team & family but she's also overconfident and somewhat arrogant. Just like Ben 10 in Alien Force/Ultimate Alien, Gwen 10 announce her alien forms' name when transformed.

When Gwen 10 enter a situation, or saw her family and friends hurt, she tends to grew extremely aggresive and violent, as it shown in Chapter 27: Ultimo Attack, Young Gwen witness the death of her favorite alien form, Grid Master, in the hand of BioCore. She completely lost it, transform into Way Big and land 50 powerful blows, killing BioCore.

Gwen even grew enrage when she recieve lack of information or if people talk badly against her & her family.

At age 10-11, Gwen 10 wore the similar attires as the original Gwen. At age 15-16, she has the Omniverse looks.

When Gwen 10 turn 22, she now has longer orange hair, wore her classic shirt but long sleeved, colored midnight blue & blue with pale-blue cat icon, she also wore a sky-blue vest with violet stripes, white pants that stop at her knee section and white-with-blue shoes. She has great curve figure and no longer wear glasses.

Powers & Abilities
Gwen 10 possess the prototype Omnitrix (later Ultimatrix then the new Omnitrix), which allows her to modify her genetic DNA to transform into various alien species, literally making her a alien shape-shifter. Traditionally, she can only start with 10 aliens on both sagas but she instantly began to unlock more aliens faster then Ben 10 as well as scanning new alien's DNA sample.

When Gwen transform into an alien, she gets all the creature's feature, including its appearance, voice, all of its unique and special abilities and powers, strength, & weakness. Though she mostly restrain her personality, there are some cases where the transformation change her personality, like Wild Cat become more aggresive, Stinkbomb act more childish, Fire Fly act very polite & Freakazoid has a desire make cartoon rampage.

Though she use her alien forms for battle, there are few cases where she was taken by real aliens, such as the Humans (before her secret was reveal) and Solaris, who mistook AurorAngel for Angel.

She also has the Ultimate Evolution feature, which allows her to transform into the evolved version of the selected form, granting her new powers or enhanced abilities.

In addition to her Ultimatrix/Omnitrix, Gwen is the master of Judo, Karate, Kung Fu and other type of martial arts. After she executed the Omnitrix Fist for the first time, the Codon Energy has merged with Gwen's DNA, causing her to become more stronger, more faster and more durable then any normal humans

Gwen's batte skills also surpasses Ben 10's and she's tends to fight with caution in front of public and great term of strategy.

Gwen also has great intellect of builting her very own Omnitrix, as Ultimo has shown to have built the Gigatrix & the Omegatrix.

Weakness
Gwen's Omnitrix may be her main powers but it's also her main weakness. Once she's timed out, she is vulnerable for her enemies' attack and must wait until the Omnitrix is recharged.

However, that weakness was removed in the Omniverse Saga.

Gwen has great fears of spiders, as she panicked whenever a spider is nearby. However, she doesn't show fear when facing Terroranchula.

She is also clusterphobic, fear of tight space.
