After being transformed into a red monster, Quickfire had only a semblance of memories of her human self, though she still had her time control powers. As the monster, she possessed sharp claws and fangs and long red horns on her head, and she could infect other humans and change them into alternate versions of themselves.

As a human, Barbara McDevitt had years of corporate spy training including diving and hand-to-hand fighting. She had access to the resources of rich employers like Jason Quantrell.

History: (Mighty Avengers II#4 (fb) – BTS) – Barbara McDevitt spent over a decade working as a corporate spy.

(Mighty Avengers II#5 (fb) – BTS) – McDevitt was always careful to avoid super heroes, who she found silly.

(Mighty Avengers II#4 (fb) – BTS) – McDevitt took a job as personal security for Jason Quantrell, the CEO of Cortex Incorporated.

(Captain America & the Mighty Avengers I#2 (fb) – BTS) – McDevitt's job with Quantrell paid seven figures and required bodyguard duty, corporate espionage and the occasional assassination.

(Mighty Avengers II#4 (fb) – BTS) – When the Terrigen Mists blanketed the earth, McDevitt was transformed. After being stuck in a cocoon for two days, McDevitt emerged looking the same but discovered she had the ability to slow down time. She began experimenting with her powers, discovering she could focus on one target at a time without difficulty. She adopted a black and white costume and took the code name Quickfire. She read reports about other Inhumans including Lineage and Fulmina.

(Mighty Avengers II#4) – Quickfire stood by while Quantrell recorded an advertisement for the company. Quantrell wondered if he could research Terrigen and give powers to normal humans so he sent Quickfire to the ruins of Attilan to try and steal some. McDevitt used diving gear and repurposed Stark tech to sneak past security into Attilan.

(Mighty Avengers II#5) – While Quickfire searched Attilan, Quantrell broke radio silence and called her to check in, frustrating her. Upon entering an armory, she identified the dangerous Lost Talisman of Tamar-Kaj just as some of the Avengers entered (Power Man/Victor Alvarez, Ronin/Eric Brooks, Spectrum/Monica Rambeau, White Tiger/Ava Ayala). A strange three-headed werewolf jumped into the room, distracting Ronin and Power Man, so Quickfire turned her time-slowing powers on Spectrum, who easily evaded the time distortion as she was faster than light. McDevitt drew a loaded gun but Spectrum phased through the bullets and downed Quickfire with an energy blast.

(Captain America & the Mighty Avengers I#2 (fb) – BTS) – McDevitt was sentenced to a time in Ryker's Island Penitentiary.

(Captain America & the Mighty Avengers I#2) – McDevitt was shocked to see Quantrell in her cell, offering her a job with him again. She took his hand and he teleported her out then dropped her in a vat that would increase her powers, telling her to think of it as a secondary Terrigenesis.

(Captain America & the Mighty Avengers I#4 (fb) – BTS) – McDevitt transformed into a red horned monster, who was capable of changing others through infection into monsters like her.

(Captain America & the Mighty Avengers I#3) – McDevitt stabbed Gideon Mace at Quantrell's order.

(Captain America & the Mighty Avengers I#4) – McDevitt watched over the body of Gideon Mace, which was transforming into a creature like her. Her thoughts were no longer coherent, instead turning animalistic.

(Captain America & the Mighty Avengers I#5) – McDevitt watched from the shadows as White Tiger and Power Man battled the transformed Gideon Mace. When the heroes were distracted, McDevitt attacked, trapping White Tiger in a time bubble, then she impaled White Tiger with her claws, planting an infection that would change the young hero as well. Soon, White Tiger, Power Man and Gideon Mace were all creatures like McDevitt.

(Captain America & the Mighty Avengers I#6) – Quickfire, Power Man, White Tiger and Gideon Mace attacked She-Hulk, Captain America (Sam Wilson) and Kaluu of the Avengers. During the fight, Quickfire used her chronal powers to slow Captain America's shield then she sped time up to allow White Tiger to gain on She-Hulk, who was soon changed into another red monster. When Power Man changed Kaluu, the five monsters closed in on Captain America.

(Captain America & the Mighty Avengers I#7) – Captain America easily knocked Quickfire unconscious. The others were transformed back when Jason Quantrell, who was exposed as being connected to the Beyond Corporation, was defeated.
