Ami Han is the last of the Kumiho, a mystical Korean shapeshifting nine-tailed fox, known for hunting by seducing men in order to tear out their hearts and eat them. Her grandmother was a Kumiho who fell in love with the man that helped her uncover her humanity.
Ami was raised by her mother (also a Kumiho), who taught her how to hunt and turn into a Kumiho, advising her to hide her true form from the others. She witnessed her mother been killed by Samjokgu, three-legged dogs who hunted down the Kumihos until their near-extinction, while Ami herself was hidden. Years later, Ami, a high schooler living with her uncle and aunt, befriended a girl whose father owed money to the Yongsan Brothers, a dangerous Seoul gang. When the gang kidnapped Ami's friend, Ami came to rescue, defeating the gang and its leader, a Samjoksu. Afterwards, Ami was invited by an National Intelligence Service agent to join the agency. As an adult, Ami became the director of the NIS, also leading the agency's superhuman response team, Tiger Division, under the superheroic alter-ego of the White Fox.
The White Fox started to investigate the mysterious disappearance of her fellow agent Gun-R once his body was found, eight months after he had vanished. White Fox's investigation concluded that Gun-R had been snatched away to an alternate universe. Despite having past experience with other universes and pocket dimensions, she believed she would need assistance to further confirm her theory and to prevent anyone else from being abducted like Gun-R was. She sought the help of the Ultimates to this end.
White Fox and the Ultimates traveled to the Grandmaster's hideout. The Grandmaster revealed that he had, in fact, forced Gun-R to compete in his latest Contest of Champions. White Fox lashed out at the Grandmaster, but he preferred to make a deal rather than fight her: if she and the Ultimates left, he would tell them who had killed Gun-R and won the Contest, as well as this individual's location. In this way, White Fox learned of the Maestro and his control over the ISO-Sphere. Miss America created a portal to Battleworld, and White Fox joined the Ultimates against the Maestro.
Upon their arrival to Battleworld, they were attacked by the Symbioids, creatures that had formed from the remains of Venom and the Void. White Fox held her own against the monsters until the survivors of the Maestro's Contest of Champions escaped and joined the battle. Madame Hydra attempted to mind-control the Symbioids, but was killed by the Maestro. This led to Blue Marvel attacking the Maestro, who repelled him and sent him, along with the rest of the Ultimates and Night Thrasher, back to Earth with no memories of what had happened there. He purposely did not banish White Fox, as he wanted her as a competitor in his next Contest. White Fox joined the remaining champions and went renegade.
When Maestro decided to confront the contestants directly, Outlaw managed to snatch the ISO-Sphere from him and use its power to wish for the contest to end by banishing Maestro. As the ISO-Sphere shattered, it teleported the contestants to wherever they wanted to be. White Fox and the contestants from Earth-616 were teleported back to their native universe, and seemed interested in the idea of forming their own team to protect the world.
White Fox allied with Domino, Black Widow, and the Posse in order to recover and destroy the Creation Constellation, an artifact capable of turning humans into Celestials, but when the team found out White Fox intended to get infected by the Constellation in order to gain cosmic power, White Fox was kicked out of the team.
Later, White Fox returned in possession of the Creation Constellation, which she had stolen from the Iron Man Sentries, so Domino could use it to defeat Geun the Executioner (Dr. Geun), returning both Neena and Doctor Geun to normal. Later White Fox rejoined the team in order to invade Hogar Hernández Para Jóvenes En Riesgo in Costa Rica, where a mutant girl was kept as a prisoner, as seen by Domino while she was under the influence of the Creation Constellation.
New Agents of Atlas
During the War of the Realms, White Fox, leading the South Korean Army, fought alongside fellow citizens Luna Snow and Crescent against an invasion of Fire Demons from the realm of Muspelheim attacking Seoul. She lead the South Korean heroes against Brawn (Amadeus Cho) and the Protectors (who came to help stop the invasion), believing that they were allies of the Fire Demons. She later lead the army against Sindr, the Queen of Cinders, but when Sindr threatened to summon a volcano in the middle of the city, White Fox, against her will, was teleported away from the battle by Brawn alongside the other heroes, minus Luna Snow.
Later White Fox helped Brawn infiltrate the Fire Demons' Army in order to rescue Luna Snow. After the Agents discovered Sindr's plan to to melt the polar ice caps, Ami and the other heroes stopped their infighting in order to save the world.
While the rest of the team fought Sindr and decreased the Arctic temperature, White Fox, Crescent, Silk, Sword Master, and "Tūtū Pele" were teleported by Agent Woo to Atlas' ally Sun Wukong of the Ascendants in Northern China, where Shang-Chi began training them for their final fight.
After the training, White Fox, in her kumiho form, fought alongside the Agents of Atlas against Sindr's army, attacking Sindr after "Tūtū Pele" sacrificed herself in order to weaken the Queen of Cinders, but she was easily subdued, reverting to her human form. When Sun Wukong also sacrificed himself, further weakening Sindr, the Agents used what they learned in Shang-Chi's training to defeat her. Despite being given the chance by Jimmy to surrender, Sindr fled using the Black Bifrost. The Agents follow her using Brawn's teleporter, where they helped Captain Marvel defeat her and her remaining forces at the Great Wall of China. After Malekith's defeat, White Fox was seen helping to put out a fire while the Agents helped the Shanghai population recover from the war.
White Fox fought the Living Monolith near the South Korea border, who absorbed Ami's life-force and left her for dead. After having a vision of her grandmother where she offered a Yaewoo Guseul to Ami, White Fox went to a Kyoto Museum to retrieve the "Fox Marble" so she could recharge her power, as it could have taken months for her strength to restore naturally. After fighting the Dokkaebi inside the museum, and realizing that one of them had the Yaewoo Guseul stored inside his body, Ami as the White Fox seduced and absorbed her boss' life force at a NIS karaoke party.
Taskmaster was hired to infiltrate Tiger Division and take Ami's kinesic signature. When he was discovered, she attacked him using the White Fox costume, and they exchanged blows before Black Widow arrived with the intent of killing him. White Fox was angry about this trespasser and was about to fight Black Widow when Taskmaster triggered a psychic blast that knocked out both, along with everyone else in the Tiger Division facility, allowing him to escape.
