Uvian

Uvian was a former member of the cult known as the Children of Arion. As the name of the cult implies, she is allegedly the daughter of Arion. Like members of the cult, she worships the Dark Giants her father worked to seal thousands of years ago.

History
A child of Arion, she came to worship the Dark Giants and awaited a thousand years for the moment to usher in the release of the Dark Giants.

Powers and Abilities
Despite being alive for over a thousand of years, she shows no obvious signs of aging and is possibly immortal like her father. Despite this,however, she can still be killed.

Being a "true Atlantean", she is capable of sorcery. She is skilled enough to teleport the Secret Six team into the deep ocean and surround them in a dome to protect them from the pressure of the ocean. Her magic seems to stem from invoking the power of the Dark Giants and causes her to take a more grotesque appearance.
