Hex (Ben 10)

Hex is one of the main antagonist in the Ben 10 series. He is an evil sorcerer who self proclaims himself a "master magician". He is also related to another nemesis to Ben, charmcaster (she is his niece), who he raised as his own daughter after her actual father's demise.

Appearence
He is depicted as a thin white skinned man with tattoos over his body and face, which has a skull-like feature due to the black tattoos over his eyes and chicks. He also wears a cape and a hood and carries a snake-headed staff with him all the time, presumably the source of his magical powers.

Ben 10
Although he's battled Ben several times, he is not his primary nemesis, that one being Gwen. He makes his debut in the episode "Lucky Girl", where he tries to recover the five Charms of Bezel and acquire the "Archamada book of spells", these itens combined grand the wielder unnimaginable power, though he fails, thanks to the Tennyson's interference, most notably, Gwen's. Hex returns in Tough Luck; his niece Charmcaster breaks him out of prison. Together, they search for the Keystone of Bezel, which he plans to use to recreate the other five Charms and multiply his power tenfold. Again, Gwen gets the Keystone and is soon attacked by the pair. Hex fails again due to both the Tennysons interference and Charmcaster betraying him so she can take the Charms for herself (though she fails as well).

Ben 10 Alien Force
Hex makes his return during the third season, but now he's got a different outfit, more reddish instead of the previous red and black one, with a whiter face, looking even more like a skull, and living in a japanese styled mansion, where he keeps his magic books. In Time Heals, Gwen infiltrates his house to steal the Grimoire of Archamada, and, despite Paradox's warning, uses it to time travel to the past and stop Ben and Kevin from hacking the Omnitrix and preventing Kevin's mutation. Though she succeeds, her action causes Hex to take over the world. No thanks to his magic, the Master magician knows that Gwen is responsible for the creation of this future, and tries to prevent her from turning the future back to normal. However, after a short fight against Charmcaster and a possessed Kevin, Gwen finds the prison and frees Ben who helps her get back the Grimoire of Archamada and gain enough time to go back in the past and prevent herself from changing the future.

Powers and Abilities
Being a sorcerer, Hex is skillful at a variety of kinds of magic, mainly black magic, dark magic and misticism. He is also a competent spellcaster, potion maker and illusionist.
