Whirlpearl

Warrior princess of an alien world, Whirlpearl fell in love with Redraider and decided to leave her planet and join him on his quest. She possesses a magic gem that lets her enlarge defeated monsters, and can create protective pearl-shaped force-fields with her mind. Whirlpearl's fighting skills were honed to perfection on her homeworld, and her skin is as hard as abalone shell, so she can hold her own even without her magic.
