A member of the "third generation" of the Magnakai.
Swift Fox has perpetually-scruffy blonde hair and blue eyes.  On her left cheek is a claw-shaped scar, souvenir of a deadly battle she fought in the Darklands.  She is short for her age, with a naturally high agility which led to her mastering the discipline of Huntmastery quicker than most and inspired the first part of her Kai name.

Her Kai Cloak and tunic and the red Gourgaz Hide body armour she wears are ragged and tattered, having suffered heavy battle damage during her mission so far.  On her head, she wears a diadem with six diamonds that seems to occasionally give her some sort of healing powers equal to the Magnakai Curing ability.
Recently she has also taken to wearing a red scarf with an odd pattern of stitching in it, a black Korlinium doublet, and a pair of dragon-shaped earrings taken from a stash of magical equipment once owned by the High Priest of Vashna.
On her back, she carries a strange shield with a reflective glass surface.  Despite the apparent fragility of the mirrored face, it seems to have withstood previous battles well, hinting at some sort of magical reinforcement.

Her favourite weapon is the dagger and she currently carries several, her main weapon made from a silvery metal with strange spiral shaped runic jade designs in its hilt.  This weapon, which she refers to simply as 'The Jade Spike', was recently revealed to have been taken from her father after his capture.  The weapon seems to possess the potential for various effects, and so far it has demonstrated the ability to kill with a single strike under certain conditions, and it has also been implied to be able to penetrate magical shields and armour while empowered in this way.

She is also known to be skilled with a bow, though perhaps not as much as some other Kai.  She carries a Kagonite Arrow which seems to be magically enhanced in some way to pierce through armour and even solid walls.
Silver Raven carries a similar arrow which appears to be an exact duplicate of this.

Since she rescued Silver Raven from the dungeons of Argazad, Swift has been learning some Kai Crafting techniques from him, apparently seeking a new purpose in life...
