History Edit

Personality Edit

Gwen is always trying to plan ahead and calculate the consequences of their (mostly Ben's) actions, because she is convinced that Ben never thinks before he acts.

Powers and Abilities Edit

Gwen is a capable gymnast and has had some training in martial arts. She has also shown an almost innate skill in using various complicated devices or objects, such as in the hiatus 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. However, her most potent abilities lie in her ability to use magic.

Magic Edit

Main Article: Gwen Tennyson's Magical Ability

In the original series, Gwen's powers first manifested in the form of what she originally believed to be "magic", actually her Anodite heritage, thus enabling her to use various magical artifacts 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 an energy blast—according to Charmcaster, only someone of Hex's skill should have that power. Gwen starts tapping into her magical powers when she procures a book of spells from Charmcaster in the episode "A Change of Face".

On two occasions, Gwen used the Charms of Bezel to become a super heroine by the name of Lucky Girl. At first, her ability drew from the "luck" Charm of Bezel, which innately gave her 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. She later brought back her superhero identity after obtaining the Keystone of Bezel, which 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.

Martial Arts and Gymnastics Edit

Gwen has proven herself to be a capable martial artist, able to fend off her own attackers with a well timed kick or punch. She is also able to perform backflips and cartwheels proficiently, in Alien Force she has become a black belt.

Intelligence Edit

Gwen is shown to be quite intelligent and knowlegdeable (if more so than Ben). 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.

Alternate Gwens Edit
