Phantom

Phantom is a girl that first appears in a Street Fighter Side Story named "Toxicity", that revolves around what happened to F.A.N.G after the events of A Shadow Falls in Street Fighter V.

After the fall of M. Bison and Shadaloo, F.A.N.G. retreats back to the city of Shanghai and regroups his efforts into reviving Shadaloo once more.[1] After a night of carousing with old associates and reestablishing ties to help fund his efforts during the Chinese New Year,[4] he takes notice of a teenage girl attempting to make ends meet through soliciting herself through prostitution.[5] Taking note rather of her spirit, and held at blackmail by her brother who had recorded him through his smartphone,[5] he offers the two three options: an offer of money, secretly poisoned to ensure the death of either of them and potential destruction of their clientele; an ornate snake handled dagger, which would have him slice off the hand of the one that would grab it; and neither, allowing both to escape with their lives.[6] The sister instead takes note of the inscribed words on the dagger's blade and its beauty, desiring to know more about its origins. Revealing to her that such a dagger was infact the Nguuhao's most coveted possession beholding the Poison Hand's secrets to its most powerful technique, F.A.N.G. offers to take the girl, who he names "Phantom", under his wing and train her as a successor.[6]
