Charmcaster

Hex's niece and a master of spellcasting.

Charmcaster is Hex's niece, a sorceress who initially appears loyal to her uncle but is later revealed to have been using him to pursue power for herself. Her exact age is never stated in the original series, though she is depicted as older than 15 in later appearances. She first appears in the Ben 10 original series as a recurring magical adversary for Ben and Gwen Tennyson. Her abilities include mana manipulation and spellcasting, and she primarily serves as Gwen's archenemy.

Affiliation
Formerly the Negative 10 (assembled by the Forever King)

Lore & Background

Charmcaster is introduced as Hex's niece, a self-proclaimed master magician's apprentice who initially seems loyal to her uncle. However, in the episode "A Change of Face", she attempts to swap bodies with Ben to gain possession of the Omnitrix, but the spell accidentally hits Gwen instead. The plan ultimately fails, and Gwen steals her spellbook, though this does not grant Gwen access to magic in the original series (Gwen only learns magic later from Hex's book in the original series episode 'The Unnaturals' (Season 4), not in Alien Force). Later, Charmcaster joins the Negative 10—a team assembled by the Forever King, not the Forever Knights—to seek revenge on the Tennysons, though her primary grudge is against Gwen. Her abilities include mana manipulation and spellcasting, making her a persistent magical threat.

In Their Own Story

In "Tough Luck", Charmcaster is first seen alongside her uncle Hex, but her true ambitions are revealed in "A Change of Face". There, she attempts a body-swap spell to take the Omnitrix from Ben, but the spell misfires and swaps her with Gwen instead. After the plan fails, Gwen steals Charmcaster's spellbook, giving her access to magic. Charmcaster later joins the Negative 10, a team of human enemies assembled by the Forever King, specifically to get revenge on the Tennysons—though her primary grudge is against Gwen for taking her spellbook.
