Gwen Tennyson

Gwen Tennyson is the main female protagonist of Cartoon Network's Ben 10 franchise and the paternal cousin of the eponymous character. Gwen's most popular incarnation is from the original series, where she is depicted as a 10-year old girl with latent magical powers who constantly bickers with Ben.

Long considered a /co/ favorite, the Lucky Girl has experienced both good and bad luck in the Ms. /co/ tournaments. She has competed in two such editions since her debut in 2019. Gwen usually appears near the top of the bracket seedings list, which has helped her make it to the fourth round both times, but missed out on an elite eight spot to Azula in 2019 and Chel in 2020.

In 2018, Gwen was considered ineligible to compete by the host due to her young age.

She will be eligible for the 2021 contest.
