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. She uses her laptop to research any strange people and/or creatures they might come across. Although she holds Ben in contempt and insults him with dry wit and sarcasm most of the time, she has some respect for him.

Alternate Gwens

Gwen 10

Gwen, in the episode, "Gwen 10" found the Omnitrix instead of Ben. Making her hero of ten alien forms. Not all alien forms were seen with the exception of a few. The forms that had were seen are Heatblast, Fourarms, Diamondhead, and Grey Matter. She does mention others, but they were never seen. She is shown to be skilled with the Omnitrix than Ben, when he found it.

Gwendolyn Tennyson (future Gwen)

Twenty years into a possible future, Gwendolyn has become a master sorceress and has even learned how to recreate the Charms of Bezel. She has also become a superhero in her own right; most likely dealing with magical enemies, while Ben deals with aliens. She has also gained her black belt, in some unknown martial arts, and is a worthy opponent even for Ben 10,000. And after the events of "Ben 10,000" she and Ben have even grown to discuss actual issues with each other.

Powers and Abilities

see also: Gwen Tennyson's Magical Ability, Magic, Charms of Bezel
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.

Overall, her most notable skill is her innate, if untapped, natural ability at magic. Having within her what Charmcaster calls a "magical aura", Gwen is capable of using various magical artifacts and spells. When using the magical, luck-giving Charm of Bezel, she was able to activate it instinctively, whereas Hex did not. Later on, when she gets a hold of his staff, she was able to make it fire an energy blast — according to Hex, only someone of his skill should have that ability. Gwen has only recently started to actually tap into her magical powers to help Ben using a book of spells she took from Charmcaster in the episode "A Change Of Face". In the possible future of "Ben 10,000", Gwen's physical and magical training leads her to become both a black belt and a master magician using the recreated Charms of Bezel, which makes her more than a match for any adversary.

On two occasions, Gwen has used magical items known as 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 literally gave Gwen supernatural luck. While wearing the charm, any action Gwen took would result in an implausible 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 affecting her luck. Both times, Gwen was forced to retire when the Charms of Bezel were destroyed. Gwen's future self apparently learns to recreate the charms somehow, as they are an integral part of her costume.
