Iduna is a redhead Native American who was a headstrong girl.

When she was a little girl, she survived when her tribe and family (who made peace with Aliens) was taken by the whites.

Iduna was heartbroken when she was the last of her tribe. She walked and walked and walked into the unknown and she found her ancestor's temple to live on.

As an adult, Iduna guards the Sapphire Master Emerald and she's a bit "OVERPROTECTIVE" by its power.
