==Personality==
As a child, Gwen was portrayed as an intelligent, sassy and mature girl who displayed a stubborn, smart-mouthed side, especially when dealing with her cousin, Ben. Her quick thinking and good instincts gave her an edge in dealing with dangerous situations, even without powers.Truth Although she generally acted with more maturity than Ben, she could occasionally be nearly as childish and disruptive as him, as she was shown to enjoy taking Ben down a peg.Big Fat Alien Wedding She could also be pretty easily riled up, particularly if her cousins were involved.Mud is Thicker Than Water However, she was consistently shown to be deeply caring and supportive, and strongly valued her family, even if she regularly bickered with them. While she initially acted in a supportive role to Ben alongside Max, over the course of the Original Series, Gwen started taking an interest being a hero herself, and eventually started learning magic.
Gwen is shown to be a gifted academic, and from a young age, she partook in multiple extracurricular activities to the point where she can be seen as an overachiever. For example, at age 10, she was part of her school's Jujutsu team and treasurer of its science club.Ghostfreaked Out She is very organized and enjoys planning things out (having meticulously planned out her whole summer when she was 10), and is shown to have aspirations for getting into good schools.The More Things Change: Part 1 Her studious nature, irritability, and her sense of responsibility tend to lead her to be seen as uptight, or relegated as being the "responsible one", much to her chagrin. Gwen was shown to be interested in technology, and often used her laptop to do research on the enemies the Tennysons came across during their road trip,The Unnaturals and continued acting as researcher for the team into her teens.Hero TimeNight of the Living Nightmare
By her teens, Gwen has become even more mature, caring and sympathetic, and even somewhat soft-spoken. She is less easily annoyed by others, and her relationship with Ben has since become more mutually supportive and affectionate.Ben 10 Returns: Part 1 Gwen has grown to be forgiving and empathetic, even towards her enemies: if she believes they have changed for the better, or if they have the capacity of change. This is most evident with Kevin (who had tried to kill her on two occasions),FramedBack With a Vengeance but also her archenemies, Hex and Charmcaster. By this point, her interest and mastery over magic has only grown, applying her studiousness to gain considerable skill in it in just a few years, despite being entirely self-taught, and has since become an important part of her identity.
Despite being more serious and reasonable than Ben and Kevin (often becoming their voice of reason for the both of them), Gwen is still somewhat hotheaded and can lose control of her mana if angered enough.Double or Nothing Additionally, Gwen still retains some of her irritable, sassy traits (though not nearly to the extent of her younger self), and she occasionally enjoys making fun of Ben and Kevin, especially if either of them are acting immaturely.Pet ProjectUltimate Aggregor In spite of apparently maturity and improved relationship with Ben, Gwen still gets openly frustrated with him on occasion, and can get just as frustrated by her other cousins as well. 
Gwen occasionally prioritizes things incorrectly, seen when she put more importance on Ben arriving to Julie's tennis match on time than stopping the Forever Knights' armed robbery of the Bellwood Museum.Duped

===The Spark===
Gwen's magical powers are of alien descent from her grandmother Verdona, a member of a free-spirited alien race of pure energy beings known as Anodites, from the planet Anodyne. Though she technically did not inherit these powers, she shares a "knack" for mana manipulation, referred to by Verdona as "the spark". This is possibly because Verdona manipulated mana in her human form. Gwen's powers are enhanced when she is given an excess of mana, such as in Legerdomain.

Gwen's mana beams can phase through the ground, as shown when she used one to hit Octagon from afar.Don't Fear the Repo

However, there is a limit to what types of constructs she is capable of creating.

Dowsing can also be used to identify someone even if the person in question is deceased, as was the case with Victor Valadis.Revenge of the Swarm
Gwen can distinguish beings with physical similarities, such as Ben and Albedo, by reading their auras.
Gwen can discern multiple minds inhabiting one body, such as when she was able to detect Ra'ad when he had fused with Ben as Ampfibian.Fused

Gwen can see through dimensional barriers, as shown when she scanned Dagon's world to look for Esoterica.

Gwen can fly and levitate without meditating.
Gwen can increase her size, as shown during her confrontation with Zombozo.
Gwen can astral project, as shown when she used her astral form to enter the Ultimatrix to find Ben.

Gwen can unleash a burst of mana powerful enough to knock back a Tetramand.
Gwen is strong enough to throw a Tetramand over her shoulder.

Gwen's Anodite powers also increase over time. According to Verdona, it would take 60 or 70 years for Gwen to master her powers.
===Magic===
Due to having a magical aura,Charmcaster Gwen can use magic by casting spells to achieve a specific result. Though she often has to recite the incantation in order to cast a spell, she does not always have to do so, as shown with some teleportation spells.
Gwen has stated that being self-taught in magic is not so easy as it looks. For example, when trying to get into Yawatacsip, she mistook its name for "Wah Di Tah", as she knew how to read that name but not how to pronounce it correctly. Regardless, Charmcaster herself stated that her incorrect pronunciation wasn't far off for someone self-taught. Nevertheless, Gwen is already catching up to Charmcaster as of Omniverse.
Gwen's spells seem to react to Gwen's emotional desires, like wanting to embarrass Ben.Lucky GirlDon't Drink the Water

Gwen can jump high in the air.
Gwen is highly acrobatic, able to execute a backward somersault in mid-air.
Gwen has enhanced reflexes, allowing her to dodge attacks with ease.

When preferring to use her athletics during fights or when she cannot rely on her powers, she is shown to be highly skilled in hand-to-hand combat.
Gwen can synchronize her martial arts with her mana manipulation abilities. For example, Gwen once created a mana whip and used it as a weapon in tandem with her fighting skills. When Kevin asked her how she learned it, she stated that she remembered seeing it in an old movie.
===Other Skills and Abilities===
Gwen is very intelligent and knowledgeable in a variety of subjects. At the age of 10, she had a 4.2 GPA. At the age of 16, she was able to skip a few grades in high school to attend college at Friedkin University, the best Ivy League college among all the colleges around Bellwood.
Gwen is a computer expert. For example, she once used her laptop to find a pattern between the locations and activation times of the Dimension 12 portals to determine where and when Computron's minions would appear. In another instance, Gwen's computer smarts allowed her to assist Eunice in programming a genetic alteration pulse against the Xenocite infestation on Aranhascimmia.
Gwen can combine her computer expertise with her knowledge of magic, as she was able to develop an algorithm to predict the next true name of Legerdomain.
Gwen has shown herself to be quite proficient in using weaponry, such as a DNA Repair GunWar of the Worlds: Part 1 and a Mark 12 Techadorian Multiblaster.Basic Training
Gwen is proficient at driving. For example, she was able to avoid the Stalker's attacks by executing sharp turns and drifts.Video Games
Gwen is seemingly immune to the disconcerting effects of going through a Hyperspace Jump Gate, as while Ben (as Brainstorm), Kevin, and Azmuth were affected and subsequently had to recover from the effects, she was unaffected.
Gwen also does horseback riding, softball, skiing, and cross country.
While mind-controlled by Dagon, Gwen was able to levitate without meditating and run at great speeds, which was partially assisted by her mana absorption ability.
When in Sumo Slammers Smackdown, Gwen had her natural fighting skills enhanced. When her body was altered by the Kappa, Gwen was strong enough to generate an earthquake and destroy the Kappa.
===Equipment===
Gwen owns several spellbooks, allowing her to cast a variety of spells. She obtained her main spellbook from Charmcaster after switching bodies with her, and stole the Archamada Book of Magic from Hex and Charmcaster's tower. She also temporarily owned all of the magic books in Hex's library in Friedkin University when he had been turned into a totem.
Gwen has a hazmat suit, given to her by Max. The suit protects her from the effects of Corrodium and allows her to survive in space.
Gwen has a Plumber Badge, given to her by Magister Prior Gilhil.
Gwen has a Plumber suit, allowing her to survive in unsuitable environments and granting her increased defense during battles with her opponents. Kevin modified her suit by installing propulsion units and neuroshock pulsers.
Gwen owns a protection charm, which she lent to Kevin. It can protect the user only if they correctly recite the incantation on it, as Gwen stated that she would never see Kevin again if he mispronounced the incantation. It was last seen when Kevin dropped it on the ground, so it is unknown if Gwen ever got it back. 
With the Charm of Telekinesis, Gwen can fly through the air at incredible speeds and also have great telekinetic control and manipulation over multiple objects or people all at once.
Gwen owns the Staff of Ages.
Gwen keeps Charmcaster's bag in her hideout.
In Lucky Girl, Gwen took possession of the Charm of Luck, which innately gave her complete and perfect luck in everything she did. While wearing the charm, any action she took would result in a chain reaction benefiting her original intent, but usually injuring Ben in the process. She destroyed it, along with the other Charms of Bezel, at the end of the episode, preferring to be herself instead of wielding so much power.
In Tough Luck, Gwen obtained the legendary lost Keystone of Bezel, which greatly increased her natural abilities to superhuman levels rather than just affecting her luck. It was later obtained by Charmcaster in Third Time's a Charm.
Gwen temporarily wielded Plumber grenades, belonging to Max.
Gwen temporarily wore a watch which acted as a homing beacon for the Omnitrix, lent to her by Max. The watch was also linked to Max's Null Void Projector and had a gauge to indicate when the Null Void portal would close.
Gwen temporarily wielded a laser pistol, belonging to Max.
Gwen temporarily used Max's Plumber jetpack when she looked for Ben in the Null Void, which allowed her to fly.
Gwen formerly wielded a DNA Repair Gun, which she used to revert the DNAliens back to human. Simian later sold it to the Incurseans.
When in Sumo Slammers Smackdown, she had access to the Sumo Bow and the game map, which she turned into a Shuriken. However, both were destroyed by Kenko.

Gwen's raw mana attacks are useless and ineffective against certain species such as Geochelone AeriosMap of Infinity and Rock Monsters, though the latter was only an issue in In Charm's Way.
Gwen's mana constructs can be tampered with by more powerful Anodites, as shown when Verdona turned Sunny's shield into a bubble to trap her.
Gwen can struggle to determine someone's location in an area riddled with technology. She also cannot track Ectonurites, as they have no mana.Ghostfreak
Most of Gwen's Anodite powers can be neutralized by a mana disruption grenade, a power dampening headband,bracelets used by a member of the Synthroid race (as demonstrated with Verdona), or cuffs from Inspector 13's Techadon factory.
Gwen can be drained of her energy to the point of either being rendered powerless or death, as nearly demonstrated with Verdona. This can be done by trapping her in runes at midnight and exposing her to moonlight, or placing her in a machine used by the Synthroid race.
Up until Omniverse, Gwen could not transform into her Anodite form without risking losing her humanity.
Certain intense spells, such as teleportation spells, exhaust Gwen to the point of having to rest and recover, and can even make her faint if she is too physically weak. The distance between her and the location she is teleporting to is a factor to this weakness. Similarly, her spells won't work correctly if she is wearing a hazmat suit.
Gwen has arachnophobia, the fear of spiders.A Small ProblemKevin LevinVengeance of Vilgax: Part 2 She also has claustrophobia, the fear of tight spaces.Inferno
Gwen is vulnerable to being possessed by an Ectonurite.
Gwen is vulnerable to hypnosis.Midnight Madness
Gwen can be immobilized by ice, as shown when she was frozen by the DNAlien Freeze GunsEverybody Talks About the Weather and in the Perplexahedron's frozen room.
Gwen can be rendered unconscious by sedative quills, such as those generated by Argit's species.Kevin's Big Score 
Gwen can be trapped in an Arachnichimp's webbing. She can also be ensnared by vines generated from MethanosiansNight of the Living Nightmare and Florauna.Weapon XI: Part 2
Gwen can be rendered unconscious by a Methanosian's sleeping spores.
Gwen can be immobilized by Addwaitya's crystallizing attacks.
Gwen is vulnerable to strong winds.
Unless she is wearing a protective metal helmet, Gwen is vulnerable to the mind-controlling abilities of Dagon and the Lucubra.
Although her intelligence and knowledge have only increased since her youth, Gwen is not completely free of her naivete, and at times can be arrogant. Gwen can occasionally be too trusting with people who want to exploit her good will, leading her or others into harm's way. For example, after P'andor was released from his containment suit, she believed he would stop absorbing energy if he were taken back home. When she told him she had contacted the Plumbers to do so, he attacked her.
Overall, while Gwen is immensely powerful, she almost always holds back in battle to avoid injuring her opponents to where they can gain the advantage and potentially injure her instead. She is also weaker than her other Anodite relatives.

*In Alien Force, Gwen was in her freshman year of high school.
*When Matt Wayne wrote What Are Little Girls Made Of?, he was under the impression that going Anodite would destroy Gwen's body. This was also mentioned by Verdona in the episode. However, when Gwen assumed her Anodite form in War of the Worlds: Part 2, she was able to revert to human with her body intact.
*By the time of late Season 1 of Ultimate Alien, Gwen had already written her college essays.
*Gwen has the potential to live as long as she wants to, if she ever chooses to allow Verdona to train her.
*Gwen and Kevin are famous on Earth, just not nearly as famous as Ben. Dwayne McDuffie compared their level of fame to that of American television personality Gayle King. However, Gwen is not very famous in space. 
**As of Omniverse, Gwen's alter-ego Lucky Girl has a fan page.

*When they were kids, disliking Max's cooking was one of the few things Ben and Gwen agreed on.
*In the initial stages of the Original Series' development, Gwen was written as a classmate who happened to be friends with Ben, and had no familial relation to him.I-10: The Ben 10 User Generated Experience
*Gwen's Original Series design was made by Dave Johnson. 
**One of Gwen's concept designs had long hair and a red and yellow raglan shirt with a mushroom on it. However, Cartoon Network nixed the mushroom design due to drug connotations.
* Gwen's design in Season 1 of Alien Force was created by Glen Murakami and finalized by Glenn Wong, with colors added by Chris Hooten.

*Gwen's Omniverse design was created by Derrick.
**Gwen's second design in Omniverse bears some resemblance to Velma Dinkley from the Scooby-Doo! franchise.
*The out-of-universe reason for Gwen's mana being recolored from blue to pink was because the crew decided that the color palette needed a review. Regardless, changing the color of Gwen's mana was not Duncan Rouleau's favorite choice.
*There have been several attempts at making a spin-off series focused on Gwen, including an anime planned in 2013, but none of them have come to fruition.

**Very little is known about Dimension 23's Gwen, other than the fact she is shy.
**Benzarro's Gwen is also scientist constantly working on a cure for Benzarro from a secure secret bunker.
**Nega Ben's version of Gwen is a cheerleader with strawberry-blonde hair of average intelligence. However, she acts less smart than she really is. Much like her Prime Timeline counterpart, Gwen is dating Kevin.
**It is unknown if a counterpart of Gwen exists on Mad Ben's dimension.
