Gwen Tennyson

**Gwendolyn "Catherine" Tennyson** is an Anodite Plumber, the paternal cousin of Ben Tennyson and was a main member of his team.

## Appearance

### Regular Appearances

#### Human Form

She has long red hair in a ponytail, and she wore a dark blue shirt paired with a black vest, gray jeans, and black flats.

#### Anodite Form

Her Anodite form's, or Lucky Girl alter ego, skin is purple. Her hair remains the same length as her human form, but is now made of mana and is pink and her eyes also turn pink. Her form now has clothes. Her glasses become a blue mask and she now wears blue gloves and her shirt is a darker blue with a light blue stripe. Her shirt cuts off and reveals her midriff and naval. She also wears blue boots, a dark blue miniskirt with a light blue stripe and a belt. The cat logo on her shirt also becomes black with pink eyes.

### Occasional Appearances

In the original series, her pajamas consisted of a long-sleeved purple T-shirt with a crescent moon on it, as well as long blue pants.

## Personality

In the original series, Gwen is portrayed as an intelligent, mature, caring, and sympathetic. Her quick thinking and good instincts give her an edge in dealing with dangerous situations. Her affection towards her cousin Ben is very clear. Gwen is willing to forgive villains for their wrongdoings, the most notable being Kevin, if she believes they have changed for the better.

Despite being far more mature and reasonable than Ben and Kevin, Gwen is somewhat hotheaded and can lose control of her mana if angered enough.

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 a museum.

## Powers and Abilities

### Mana Manipulation and Energy Control

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. Gwen didn't inherit the powers, but shares a "knack" for mana manipulation, possibly because Verdona manipulated mana in her human form. Verdona herself has explained to Gwen that, like herself, she is an Anodite and has "the spark," and thus is able to freely manipulate and control mana or life energy, the substance of magic. According to Charmcaster, Gwen is filled with mana, having been born made of magic while she had to "work her but off for her powers."

Gwen can create energy blasts, streams, waves and bolts, as well as energy force-fields, shields and barriers. Her powers are mainly used like energy constructs, allowing her to make many different types of structures like, hammers, protective helmets, battering rams, beams to grab and throw enemies, stepping stones/platforms to carry her and others though air, safety nets, magic weapons: swords, blades and punches, though there is a limit to the types of constructs she can create. It also turns out Gwen can also synchronize her martial arts styles with her energy manipulation abilities.

Gwen has more mana-related powers: she can use mana to track down a living thing by following its energy trail, find any person she wants by detecting the traces of mana that they left, or by being at one with the cosmic mana. She can distinguish Ben and Albedo by reading their auras. She can also draw in mana from everything around her. She also has a degree of enhanced strength and durability.

Gwen has the abilities of telekinesis, teleportation, heat vision, clairvoyance, telepathy and healing herself and other living beings.

Gwen can transform into an Anodite, which greatly enhances her other powers and expands to include flight and size alteration. In addition, her Anodite powers get stronger over time.

Because Anodites lack DNA, Gwen is immune to being reverted into human form by the Forever Knights' DNA Scanner, as well as the lethal effects the device has on hybrids.

### Magic and Spells

Gwen is seen using magic through casting magical, mystical spells, and reciting spoken incantations thus enabling her to use various magical powers and abilities. She can also fire magic blasts from her eyes.

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 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. Gwen later brought back her superhero identity after obtaining the legendary lost Keystone of Bezel, which greatly increased 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.

Gwen claims that being self-taught in magic is not so easy as it looks. Trying to get into Yahwahtacsip she mistakes its name for "Wah Di Tah," saying that she knows how to read it but not pronounce it correctly.

Gwen can cast spells and recite spoken incantations. Gwen is less knowledgeable than Charmcaster and Hex, having been self-taught. Despite that, she is more powerful than Charmcaster until she obtained the Alpha Rune, after which she was powerful enough to defeat Gwen with ease.

Gwen has learned to astral project through magic, like when she found Ben inside the Ultimatrix.

Gwen's spells seem to react to Gwen's emotional desires.

### Athletics and Martial Arts

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 combat fights against enemies who had normal strength levels. She was part of her school's Jujutsu team. By age fifteen, she has already received a black belt in Taekwondo.

When preferring to use her athletics during fights or when she cannot rely on her magical and Anodite powers, she is shown to be highly skilled in hand-to-hand combat.

Gwen does martial arts, horseback riding, softball, skiing and cross country.

Gwen has been shown creating a whip of mana energy and using it as a weapon along with her fighting skills. When Kevin asks her how she learned it, she states remembering it from an old movie.

### Knowledge and Intelligence

Gwen is very intelligent and knowledgeable. Before discovering her dormant Anodite powers, she would often use her superior intellect to help Ben solve problems. She is shown to be a bit of computer and tech wiz as well. She has her own laptop which she uses to research enemies she meets.

## Weaknesses

Although her intelligence and knowledge have only increased since her youth, Gwen is not completely free of her naivete. At times, she can become arrogant.

Gwen can occasionally be too trusting with people who want to exploit her good will, leading her or others into harm's way.

Unless she is wearing a protective metal helmet, Gwen is vulnerable to the mind-controlling abilities of Dagon and the Lucubra.

Gwen cannot use her Mana to track Ectonurites, as they have no Mana themselves. Likewise, her tracking does work well with non-biological life forms such as robots and Galvanic Mechamorphs.

Gwen's Anodite energy can have trouble with technology and vice versa. For example, she can struggle to divine the location of someone in an area riddled with technology.

Certain teleportation spells exhaust Gwen the point of having to rest and recover. These spells can even make her faint if she is sick. The distance between her and the location she is teleporting to is a factor to this weakness.

Most of Gwen's Anodite powers can be neutralized by wearing a bracelet used by a member of the Synthroid race, as demonstrated with Verdona.

Gwen's raw mana attacks are useless and ineffective against certain species such as Geochelone Aerios and Transylians.

Gwen can be drained of their energy to the point of either being rendered powerless or death, as nearly demonstrated with Verdona.

Gwen has arachnophobia and claustrophobia.

Overall, while Gwen is immensely powerful, she almost always holds back in battle in order to avoid severely damaging her opponents—as such, this can potentially lead to her opponents gaining the upper hand, thus injuring her instead.
