FOX (Frontial Operation X) is one of the female characters in CrossFire, available in most CF versions. The GR character wears a dark blue skirt with neck buttons undone, partially revealing her bra, while BL wears a similar yellow version but has no shelves, to showcase a tattoo on her left arm. Both characters wear long shocks and high heals as well.
In most versions, FOX is available in the Black Market, while CF China, CF Philippines and CF North America put her in the Item Shop.

- In Russia, FOX has their own Russian voice, similar to STAR in CF Korea.
- Even though the descriptions in CF North America state that FOX "stripped armor for speed", they don't actually run any faster than other characters.
- Like other popular characters in CF China, players cannot buy FOX permanently, they can only be rented for a period of time.
- FOX's GR HUD incorrectly shows hand models of the S.T.A.R, with black shirt and yellow stripe, although the gloves are correct. This happens because FOX's HUD is just a recolored version of S.T.A.R.'s HUD. Fixed in most CF versions, but still exists in CF Vietnam & CF EU.
- CF PH and CF NA released the character during the popularity of the song "What Does the Fox Say?"
- In CF Japan, she can be won permanent or 30 days.
- FOX is featured as the promotional tritagonist in CF China's Shipyard CG moive, helping the two protagonists escape death after they got transported to the Shipyard. She is shown weilding Dual Desert Eagle-Black, which is unavailable in CrossFire but this skin exists in early renders (Hinting it's a beta weapon before Zombie Mode was released).
