Gwen Tennyson is a hero in Earth-1010. She first appeared in Ben 10: Reboot Revolution Chapter 1. She is a Human in possession of an Anodite Spark. She is from the planet Earth.


Gwen is a white teenage girl of average height. She has short orange hair, green eyes, and freckles. She wears blue glasses, a light blue shirt with a face of a cat on it, and a dark blue skirt.


Gwen is smarter and more logical-thinking than her cousin Ben. She is also more forgiving than Ben, though this can be as much of a disadvantage as it is an advantage.

Powers and Abilities

Gwen is a bookworm, and is quite intelligent as a result.

Gwen possesses an Anodite Spark and as a result can transform into an Anodite form at will. She has incredible magical power.


Her powers are useless against beings that can absorb mana, such as Chromastone or a Geochelone Aerio.


Gwen used to accompany Ben on most of his adventures, however she recently moved to the outskirts of Bellwood away from Ben so that she could focus on her academic career at Friedkin University.
