Gwen Tennyson is the deuteragonist from 2016 reboot series Ben 10.
She is voiced by Montserrat Hernandez.
She is Ben's resourceful ten-year-old first cousin who uses her keen intellect and cunning to help in stopping villains. Her favorite superheroine of all time is Lucky Girl. It has not yet been confirmed if she will naturally develop powerful magical abilities, like her ten-year-old counterpart in the original show. However, in "Black Lights, Black Hearts" she was capable of resisting Michael Morningstar's life force-absorbing abilities, which clearly implies her innate magical prowess and mystical affinity. In "Story, Bored" she could cast high-level spells from the ancient and very powerful Grimoire of Arcamada with no problem. She may yet begin developing her innate magical and mystical powers in Season 3.
