Gwendolyn Tennyson, known simply as Gwen, is Ben's cousin and a main character in every series. Gwen was first introduced in the episode And Then There Were 10, when her parents send her on a summer-long trip
with her Grandpa Max and her cousin Ben. Like Ben, she is a Human/Anodite hybrid, but unlike her father, uncle, brother or cousin, she has, as her Grandmother refers to it; "The Spark". Gwen has appeared in every single episode except for Above and Beyond.

Appearance Edit

Gwen has red hair and green eyes (in Alien Force eyes and hair appear to be darker, although her skin tone looks lighter). In the original series she wears a blue long sleeved shirt with a cat on it, white pants, and white shoes. She also dons blue stud earrings on both her ears. The Lucky Girl costume is worn twice and 2 swimsuits are worn.


original series

In Seasons 1 and 2 of Alien Force she wears a white shirt under a dark blue sweater, black stockings under a black mini skirt, and black high heels. In Season 3, she wears a red shirt paired with a black vest, gray skinny jeans, and black flats. Her hair is worn in a ponytail. She also appears with 3 swimsuits and a karate gi. Her Lucky Girl outfit is also seen in Alien Force.

In Ultimate Alien, her outfit is similar to her outfit from the first two seasons of Alien Force, but with a red sweater while her hair still is styled in a ponytail.Her outfit has been scratched once.She also wears a snow jacket.

Ben 10Edit

In the original series, Gwen uses her laptop to research any strange people and creatures they might come across. She is a capable gymnast and has had some training in martial arts.

In Ben 10,000 her future self says she got her black belt years ago (probably referring to Alien Force) and it's come in handy many times. She has also shown an almost innate skill in using various complicated devices or objects, such as in the "What If?" episode Gwen 10, when Gwen gained the Omnitrix instead of Ben and proved to be far more adept in its use than he initially was, even being able to write her name with fire while Ben took a month to be able to do it (although she may be able to use it better because of her powers).

She is depicted as snobbish and very mean due to her young girl attitude. Overall, her most notable skill is her innate, if latent, ability at magic. Having within her what Charmcaster calls a "magical aura", Gwen is capable of using various magical artifacts, charms, talismans and spells. When using the magical, luck-giving Charm of
Bezel, she was able to activate it instinctively, whereas Hex did or could not. Later on, when she takes and uses his staff, she was able to make it fire a yellow-colored energy blastโ€”according to Charmcaster, only someone of Hex's skill should have that ability.

Gwen starts tapping into her magical powers when she procures a small book of spells from Charmcaster in the episode A Change of Face. On two occasions, Gwen uses the Charms of Bezel's incredible and unique powers and abilities to become a superhero by the name of "Lucky Girl". At first, her ability drew from the luck-granting Charm of Bezel, which innately gave her perfect luck and the abilities and powers of probability manipulation. While wearing the charm, any action she took would result in a Rube Goldberg-style chain reaction benefiting her original intent, but usually injuring Ben in the process. She later brought back her superhero identity after obtaining the legendary Keystone of Bezel, which greatly strengthened and increased her natural abilities to superhuman levels rather than just affecting her luck. Both times, Gwen was forced to retire when the Charms of Bezel were destroyed.

Gwen is shown to have two swimsuits; one which appeared in Divided We Stand and the other appeared in A Small Problem.

Ben 10: Alien Force Edit

Gwen is now a black belt (taking classes in Karate), but tends to favor using her powers. She is capable of creating energy constructs for nearly any purpose, usually creating platforms to levitate herself (and others), beams to grab enemies, circular blasts to knock enemies back, projecting beams from her eyes that seem to simulate heat vision, and opening up interdimensional portals. In Ben 10,000, her future self is able to create time portals. She also has a wide range of other loosely defined supernatural abilities, such as dowsing. limited telepathy, and clairvoyance. In the episode Everybody Talks About the Weather, Kevin said she gets her
Gwen mana
powers and abilities from her alien bloodline, but she refused to believe him. Little did she know that she would realize he was right in What Are Little Girls Made Of?.

Her powers and abilities are revealed to be of alien descent; her grandmother, Verdona, is an energy being known as an Anodite and surprisingly she seems to be the only human descendant who inherited Verdona's powers. Verdona tells Gwen that what she and others originally thought of as "magic" was actually the manipulation of mana, a substance of magic - making Anodites a magic-wielding race. Verdona offers to take Gwen to her home planet and train her in the mystical and magical ways of the Anodites, but Gwen prefers to remain on Earth with Ben and Kevin. She hates being called an "energy being", referring to her Anodite heritage. In the episode, In Charm's Way, it's implied that highly gifted humans like Charmcaster can also be trained to utilize mana. In episode eleven of the second season, Unearthed, an alien creature was able to see her as an Anodite, in which she looked exactly like her grandmother's true form, but slightly shorter. In the two-part season two finale War of the Worlds when Kevin was threatened by a Highbreed commander, she assumed her dormant Anodite form for the first time and easily defeated the commander with an exceedingly strong powerful burst of pure magenta-pink glowing energy. She was almost overwhelmed by her own power before Kevin snapped her out of it.

During the course of the series she has developed a romantic relationship with Kevin. They have also been shown to have arguments, usually starting with Gwen always trying to force Kevin to "ask her out" and him always answering "Don't push me" (which she once did). In the episode Fool's Gold, Kevin appeared to be avoiding her because he was ashamed of his recent mutation due to accidentally absorbing a massive feedback pulse as a result of trying to hack the Omnitrix. She was unaffected by the blast because she put an energy shield around herself. Kevin gave her a locket of the two of them when he was in his human form, asking her to remember him as he was. Gwen said she didn't care what he looks like, and he replied "But I do."

In the two-part season three premiere, Vengeance of Vilgax, Ben and Gwen seemed to have revived their

gwens anodite

infamous rivalry from the original series, in part due to Ben's cockiness and inflated ego. In the same episode, Gwen poured a smoothie over Ben's head, and he nearly returned the favor. Despite their rivalry, they both still have a strong bond, visible in the episode In Charm's Way, when Ben defended Gwen and informed Kevin that she had been spending all of her spare time trying to find a cure for Kevin's condition. It is shown in both Vengeance of Vilgax: Part 2 and Inferno, respectively, that Gwen suffers from both arachnophobia and claustrophobia.

Unlike the original series, Gwen has worn other costumes besides her usual clothing. In the episode Time Heals, it was revealed that Gwen kept her Lucky Girl costume. In What Are Little Girls Made Of?, Gwen is shown to have a white bikini. In In Charm's Way, she has a black bikini. In The Con of Rath she is shown wearing another one piece black swimsuit, pink flipflops, a hat, sunglasses, and a pink towel skirt. She also has a karate gi. In Save the Last Dance, Gwen was seen wearing a white strapless prom dress. She has kept and worn her Lucky Girl costume, which is now bigger and has a utility belt in place of the sash in the original series, with Gwen being fifteen.

Ben 10: Ultimate AlienEdit

In the sequel that takes place one year later, Gwen is now sixteen years old. Her wardrobe has altered once again, wearing a combination of her outfits from Alien Force. She wears her old outfit from the first two seasons of Alien Force, but instead of a plain dark blue shirt it is now red and she also keeps her high ponytail from the third season.

In Video Games, she tries out for her driver's license and earned it in the end. In the early episodes of the

gwen in snow suit

series Gwen and Kevin seems to be bickering constantly. Gwen's magenta-purple shields look less see through and have a different design than in Alien Force, perhaps the color intensifies as she grew stronger evident in latter episodes where she advanced her powers.

In Andreasโ€™ Fault, a little on going joke takes place when Kevin says he loves money more than anything in the world (apparently more than Gwen). Despite doing everything he can to make it up to her, she keeps saying it. Gwen's comment "Why don't you get your money to help you?" But they eventually made up.

In the episode, Hero Time, it is shown that Gwen gets very jealous when Jennifer Nocturne starts flirting with Kevin after he saved her life, and he seems to be enjoying it very much. Kevin also protected Jennifer a lot, for example; When Overlord shot an energy blast at them Kevin put his arms around Jennifer to protect her from the blow, even though Gwen put up a magenta-pink shield around them. She eventually lost her temper and threatened Jennifer that she would "peel her like a grape" if she made another move on Kevin.

In Ultimate Aggregor Gwen is seen that have great skill with mana, and in Map of Infinity it is revealed that Gwen's powers do not affect Galapagos' species and Aggregor (with Galapagos' powers) so Gwen is no match for Aggregor. From the Map of Infinity Gwen starts casting spells again, Gwen is also seen with a Plumbers' Suit. She is the only of the group that can use her powers in the suit, during her attempt to recover the first part of Map of Infinity, she discovers it was hit by a poison dart and ends up fainting, causing Aggregor catch the
first part, but Kevin can save her.

In Reflected Glory, Gwen use good abilities with mana, and is compreensive with JT and Cash, in the final of the episode Gwen is seen with her shirt torn and her hair disheveled, after she and Kevin face the RED's of Psyphon again Gwen had the idea to use a mirror against RED's, and his powers apparently did not greatly affect the RED's.

In Deep, the group goes to the planet Piscciss to help Magister Pike holds Aggregor, Gwen is caught by a squid-like creature, but Kevin revealed that it suits Plumbing can shoot lightning and she uses this ability very well, even with his powers, when they reach the nucleus of an earthquake is caused Piscciss fainting Magister Pike, Gwen failed to protect him, so she stays with him, while Kevin and Ben go after the second part of the Map of Infinity, but Aggregor arrived first and flees with the first part of Map of Infinity after defeating Ben and Kevin, when the planet begins to crumble Ben as Goop saves, bringing water from the planet, Ben apparently dies leaving Gwen sad but she sees that he survived, at the end Gwen "console" Kevin for having to leave the Little Fish in Piscciss.

Alternate Future Edit

Ben 10,000Edit

In the third season premiere, Ben 10,000, thirty-year-old future Gwen (who has been going by Gwendolyn since college) brought Gwen and Ben twenty years into the future during Grandpa Max's 80th birthday. Her hair is
now cut.

Ken 10 Edit

In the non-canon episode Ken 10, an astral projection of a 42 year old Gwen was seen during Ken's tenth birthday just to say happy birthday to him. She also seems

ken 10

to have the five Charms of Bezel in her possession though for an unknown reason, she does not have the Lost Keystone of Bezel.

Powers and AbilitiesEdit

Mana/Energy Control and Manipulation Edit

Gwen is descended from a free-spirited alien race known as Anodites from the distant planet Anodyne. These aliens have the incredible incomprehensible power and ability to manipulate and control life energy more commonly known as Mana.

In the episode What Are Little Girls Made Of?, Gwen's magical powers and abilities are actually revealed to be of alien descent inherited from her paternal grandmother Verdona, a member of a free-spirited alien race of pure energy beings known as Anodites, from the distant planet Anodyne. Verdona tells Gwen that, like herself, Gwen is also an Anodite; she has "the spark" and thus is able to freely manipulate and control mana, the supernatural Force-like life energy that is present in all living beings and things throughout the universe. Verdona offered to take Gwen back with her to Anodyne and teach her how to fully control her powers and abilities (which would require seventy-five years), but Gwen prefers to remain on Earth with Ben and Kevin. Gwen is able to create magenta-and-purple platforms, portals, shields, slides, beams, ropes, blasts, telekinesis, chains, cages, safety nets, dowsing, barriers, bridges, and energy bolts. She also possesses a numerous variety of supernatural, magic-related powers and abilities such as telepathy, telekinesis, empathy, teleportation, dowsing, clairvoyance, levitation, flight, clairsentience, cloaking,spell-casting, aura-reading, aura control-and-manipulation, auramancy, sensing, astral projection, scrying, potion-making, dream control-and-
manipulation, reality-warping, shape-shifting, premonition, illusion-casting, intuition, luck control-and- manipulation, memory control-and-manipulation, time travel, and sorcery.

In the two-part season two finale War of the Worlds when Kevin's life was threatened by a Highbreed commander, an enraged Gwen unleashes her dormant inner Anodite self for the first time and easily defeats the commander in mere seconds with an exceedingly strong and powerful blast of pure magenta-and-pink glowing energy. Kevin begs her to try to shut it down but she refuses, saying that she thinks she can defeat the entire Highbreed fleet all by herself. Kevin reminds her that her paternal grandmother said that it would take at least seventy-five years for her to fully master her powers and abilities though Gwen argues that they do not have seventy-five years. Kevin further argues by saying that she will lose her humanity entirely, that she will not remember either him or Ben, and tells her that Ben will find another way to win and wants her to come back to him because he cannot bear to lose her. Gwen then reverts back to her human form and embraces Kevin.

In episode three of Ultimate Alien, Hit 'Em Where They Live, when Zombozo threatens to make Ben suffer by endangering his mother Sandra, a furious Gwen unleashes her inner Anodite self for the second time since the two-part episode "War of the Worlds" and shows that she can grow to huge heights. It is unknown if Gwen can use this power and ability in her human form.Though this time she appears to have gained some control over the transformation as she does not appear to be overwhelmed by all of that power like the first time.This could mean that as years pass as Gwen learns to control her inner Anodite self she will gain more and more control
over the transformation until she is able to control it entirely, meaning that she will be able to switch between both her human and Anodite forms at will but it is dangerous to do so. Gwen seems to only unleash her inner Anodite self when she is under a great deal emotional anger or rage.

In the episode Fused it is shown that Gwen can trap enemies in unusually strong and powerful impenetrable electric spheres of magenta-and-purple glowing energy just like her grandmother Verdona can, meaning that Gwen's innate Anodite powers and abilities become stronger and even more powerful with the passing years.

In the episode Where the Magic Happens, Gwen claims that she feels much, much stronger and much more powerful in this new dimension of magic and mana. Charmcaster explains to her that all of the magic in the universe flows through the Legerdomain to other worlds and planets such as Anodyne. It is clearly evident that she becomes exceedingly stronger and more powerful because when using her newly strengthened and amplified Anodite abilities she is able to produce much more mana than usual and can cause random outbursts of amazingly strong and powerful magenta mana explosions.

Spells/Magic Edit

Gwen is seen using magic through reciting spells, thus enabling her to use various magical powers and abilities.

In the original series all of Gwen's spells are said out loud to activate her magical powers and abilities, but in Ben 10: Alien Force, most of her spells are said non-verbally.

On two occasions, Gwen used the five mystical Charms of Bezel to become a superheroine by the name of Lucky Girl. At first, her power and ability drew from the luck-granting Charm of Bezel, which innately gave her

foot shield

complete and perfect luck. While wearing the charm, any action she took would result in an Rube Goldberg-style chain reaction benefiting her original intent, but usually injuring Ben in the process (probably because this was part of her intent). She later brought back her superhero identity in the episode Tough Luck after obtaining the legendary lost Keystone of Bezel, which greatly increased and heightened her natural abilities to superhuman levels rather than just affecting her luck. Both times, Gwen was forced to retire when the five Charms and Keystone of Bezel were destroyed.

Five years later in Ben 10: Alien Force, despite fifteen-year-old Gwen's current preference for direct forms of mana-manipulation-and-control, she is still able to use magic in the more traditional sense. It was later revealed that what she and others all originally thought of as "magic," was actually her natural power and ability to control and manipulate a supernatural substance called life energy otherwise known as mana, chakra or chi, meaning that Gwen has always had an innate affinity for magic. Gwen mentions to both Charmcaster and Kevin in the episode In Charm's Way that she still has Charmcaster's old spell book, and is currently looking through it constantly to find a cure for Kevin's mutation.

In the episode Time Heals, Gwen borrowed the spell book known as The Archamada Book of Spells (the only spell book mentioned, seen and used in the original series) in an attempt to use a time-traveling spell that will take her back to the time when Ben and Kevin tried to hack the Omnitrix, resulting in Kevin's present rock-like form, hoping to return him to his human form. However she returns home only to discover that her time-traveling resulted in both Hex and Charmcaster ruling the world. After finding and freeing Ben she recasts the time-traveling spell to return everything back to the way it was. Back in her room she puts The Archamada Book of Spells away on her shelf and is apparently not willing to use it for some time.

In the Ultimate Alien episode, Hit 'Em Where They Live, Gwen said to Charmcaster that she is much, much more proficient at magic than ever before, having have had more study, training and practice in the innumerable levels and ways of magic. In the episode Fused, Gwen uses an unusually strong and powerful unnamed teleportation spell which envelops her, Kevin, and Ben (using AmpFibian) in a swirl of magical mystical pink and magenta energy to escape from Aggregor. However the strength and energy required to cast this particular spell seems to exhaust her pretty quickly.

In Where the Magic Happens, Gwen claims that being self taught in magic isn't so as it looks. Trying to get into Yawa Tobsic she mistakes it's name for 'Wa Di Tah', saying that she knows how to read it but not pronounce it linguistically.

Athletics Edit

Gwen is a capable gymnast and martial artist. Even in the original series, she was occasionally shown to be
quite good in hand-to-hand fights against enemies who weren't too powerful. When she was possessed by Ghostfreak, she was used to her skills combined which pretty much says that she's good. At the age of fifteen it is revealed that she has already received a black belt in Tae Kwon Do and has even started teaching Ben. When preferring to use her athletics during fights or when she can't rely on her powers like in In Charm's Way, she is shown to be agile, precise and skilled which is shown through the course of the series.

Intelligence Edit

Gwen is shown to be quite intelligent and knowledgeable. Before discovering her powers, she would often use her "brains" to help Ben. She is shown to be a bit of computer/tech wiz as well.She has her own laptop which she uses to research enemies she meets. She is straightforward and very brave despite the circumstances. In back with a vengeance, Gwen switched the Omnitrix with a bomb,saving Ben and the world, showing her cleverness. Gwen is Intelligent enough to pronounce the spells correctly in an instant, with the spells being hard to pronounce. Gwen has a strong commitment to herself resulting her to manifest her knowledge, magical and physical abilities. She also shares traits with Ben, she would stand up for what's right and fight for it and may act a little naive (trusting Charmcaster in the original series, resulting her being tricked).

Her naive nature is toned down in Alien Force; she is now even more analytical. It is highly unlikely that she will get stupefied; she is also a quick thinker and an instinctive person. But at times she trusts others too quickly, and that may disadvantage her or even injure her, like in Too Hot To Handle. She can handle things well despite the conditions (such as when her powers were drained and Charmcaster hit her with a bolt of
Gwen looks in book
magical energy and she immediately turned the spell though she had no power yet she could hold herself). Gwen is at times shown to be very concerned with things such as her surroundings, the people around her and the ones who she cares about. She is very strong (physically and mentally) and well mannered, despite her inflating sarcasm and ego at certain times. Gwen is a very caring, compassionate person such as shown from her acceptance of Kevin's past and recent action, also saying she does not care about Kevin's appearance.

Love Interests Edit

Michael MorningstarEdit

When Gwen and the others first met Morningstar in the "Ben 10: Alien Force" episode "All That Glitters", he was a charming Casanova, and there was literally a dim spark between him and Gwen. Ben, because of his eagerness to build a team, and Gwen, because of her crush on him, automatically trusted him, but Kevin resented him, mostly due to his crush on Gwen. After a battle against the zombies, Mike asked Gwen out on a date which made Kevin even more jealous. Later, it turned out that Mike had never liked Gwen, only her Anodite and magical powers and abilities. And by the end of the episode, she "came to her senses", regained her powers, and returned to Kevin's side which he was happy about.

Kevin LevinEdit

When they first met, Kevin was a renegade 11-year old, who knew Gwen as Bens smart-mouthed cousin. He later had an vengeance against Ben and almost burnt Gwen in the episode Framed. In Back With a Vengeance, Kevin holds Gwen hostage so that Ben would give up the omnitrix. Ultimately he gets trapped in the Null Void.

During the series it is evidently displayed that Gwen feels sorry for Kevin having to live the hard life such as in Perfect Day and other encounters they have. There wasn't much or barely any interaction between the two though.

In Ben 10: Alien Force, there was instant chemistry. Gwen's previous pity and admiration of Kevin turned to infatuation then love. In season one and two we see the two falling for each other. The problems they have or issues did get in the way because both of them cared about each other. In What Are Little Girls Made Of?
, Kevin didn't want Gwen to go off leaving him and Ben. The two also work well in the battle field. Whenever Gwen's knocked down in a fight Kevin would automatically be by her side helping her up and so is otherwise. Both of them would also put their life at risk in order to protect the other. Arguments between Kevin and Gwen are quite unique. Shouts were rare but instead talking sternly but quietly in each other's face makes up for it. In Darkstar Rising, Gwen tries to comfort Kevin for his father's absence and his stripped privelege. The two almost kiss until a Highbreed barged in. Their relationship grows in the second season. They danced together in Save the Last Dance. When Kevin gets mutuated after he and Ben try to hack the Omnitrix, he tries to break off things between himself and Gwen during his bouts of self-consciousness. Kevin was quite depressed, he also gave Gwen a "keep me in your memory" locket telling her to remember his old self before the accident in Fool's Gold. His appearance didn't bother Gwen but it proves
just how much he cares about it. As seen in the episode In Charm's Way, Kevin still strives hard, though he vents his frustration in the wrong way (on Gwen) thus falling for Charmcaster which made conflict. In the end, Ben tells Kevin that Gwen's been working day and night to find a cure for him leaving him to regret getting mad at her. However, he tries to make it up to her by saving her from Darkstar in Trade-Off leaving him from human form into his mutation. Gwen though still cares for him just as much such as in Time Heals and Vendetta where she'd go to desperate measures to make things up. In The Final Battle: Part 2, after Kevin returns back to normal, they share an on-screen kiss, also reviving their relationship. In Ben 10: Ultimate Alien, for the first few episodes, they both don't show much interaction, and have a lot of arguements such as in Video Games and the early episodes. However, things got settled and changed in the episode Too Hot To Handle after Gwen gets hit by P'andor's blast, he quickly held her, helping her get up, and told her not to ever do that to him like that again. Later on the episode, he made Gwen leave the power plant because he's worried about her. In Fused, after Gwen casts the spell, she nearly fainted and landed on Kevin's lap. There was some obvious eye contact too. In the episode Hero Time, it is shown that Gwen does not approve on Kevin falling for other girls instead of her. For example, Gwen threatningly told Nocturne that she would "peel her like a grape" after seeing Kevin quite happy of Jennifer thanking him for saving her life. In the episode Ultimate Aggregor Kevin kissed Gwen on the cheek after she took him to one side to talk to him, when Kevin reveals the insanity of Osmosians when they absorb energy, Gwen discovers that it why Kevin was so bad that Kevin was a child. In Map of Infinity Gwen is defeated by Aggregor and Kevin help she, soon Kevin is defeated too, when the two up, the two embrace, Ben, Gwen and Kevin are in search of Map of Infinity, where Gwen collapses under a gate that Ben and Kevin are holding the two despairing, just Aggregor takes the first
part of the map, and Kevin save Gwen. In Perplexhahedron, Kevin says he wants to take care of her in front of Swampfire and admits he likes her. And after Swampfire freed Gwen from the ice, she and Kevin kiss. Then Swampfire says in disgust "Why don't you get a room?!" In 'The Forge of Creation' and 'Nor Iron Bars a Cage', it is shown that Gwen still hasn't given up on Kevin, despite his current situation.
