When S.H.I.E.L.D. and the Avengers joined forces to oppose the entity known as the Collective, Captain America requested Daisy Johnson's assistance. Maria Hill was initially unwilling to reactivate Daisy's field status, but Cap insisted. The fight with the Collective carried over to 
Genosha, where the energy entity possessed Magneto. When Daisy arrived on the scene, she was directed to set off a micro-quake in Magneto's brain. Combined with Iron Man's efforts, the Collective was driven out of his body and thrown into the sun by the Sentry. Daisy was ready to join the Avengers under her chosen codename "Quake,” only for Captain America to awkwardly explain he wasn't offering her membership, but had only requisitioned her for this one mission. [New Avengers (1st series) #18, 20]
Daisy fell back into mandatory retirement for several months, technically a S.H.I.E.L.D. agent but blackballed by Maria Hill to keep her out of the field. When Nick Fury finally emerged from hiding to speak to her, Daisy was a little salty about being left in the cold. Fury had a new secret war, however, and he could only trust Daisy and the other potential assets from his Caterpillar Files. The alien race of shape-changers known as the Skrulls had begun to infiltrate the planet Earth. Fury had evidence some had already been placed inside S.H.I.E.L.D., and he had theories about others as well. Daisy and the Caterpillars, recruits who had not gone public and were known only to Nick Fury, were ideal soldiers that Fury could draw from without concern they had been replaced by Skrulls already.
Acting as Nick's scout, Daisy began recruiting their team. Like herself, she found the unclaimed children of super-villains like Griffin and Absorbing Man named Yo-Yo Rodriguez and Jerry Sledge. J.T. James was an apathetic convenience store clerk and the grandson of the Phantom Rider. Alex Aaron was the mortal born son of Ares and reincarnation of Phobos, God of Fear. And Sebastian Druid was the son of Doctor Druid with, quote, "Monster DNA." This small band of 
neophytes were brought together for training by Nick Fury to identify potential Skrulls infiltrating the world and prepare to fight them. [Mighty Avengers (1st series) #13] Fury spent several months training this team of commandos, his secret warriors, with Daisy as his second. [Mighty Avengers (1st series) #16] When the Skrull invasion came, Daisy and the Secret Warriors provided unexpected reinforcements to the battle of New York. They rallied the Young Avengers and Initiative heroes in Times Square, giving them time to recover before moving on to the final fight in Central Park, quelling the invasion. [Secret Invasion #3-8]
S.H.I.E.L.D. was dismantled in the aftermath of the Skrull invasion, with its assets turned over to Norman Osborn and H.A.M.M.E.R. More than ever, Nick Fury saw the need to continue operating independently, for the normal branches defending world peace were being sacrificed to corruption and expediency. Quake continued on as his second, leading the Secret Warriors in the field. Daisy learned the extent of Nick's troubles when he told her that information had been uncovered revealing that Hydra had been secretly behind S.H.I.E.L.D. the whole time. Through dummy corporations and backdoor protocols, Hydra had control of the funding and intelligence network S.H.I.E.L.D. had operated under. [Secret Warriors (1st series) #1]
Baron Strucker learned that Fury now knew of the Hydra - S.H.I.E.L.D. connection, and this escalated the situation. Fury sent Daisy and her Secret Warriors to extract S.H.I.E.L.D. psi-agents being held at the Red Worm facility, only to run into Gorgon and the High Council of Hydra making their own raid. Daisy ordered her team into action, but the Gorgon proved too much for them and Yo-Yo had her hands cut off facing him. While the Warriors licked their wounds, Fury led his loyal ex-
S.H.I.E.L.D. compatriots in the Howling Commandos to reclaim the Dock facility and its Helicarriers from H.A.M.M.E.R. This, too, led to a surprise appearance by the Hydra Council. Daisy responded to an alert summons, bringing her team in to shift the tide of battle and save the day. Nick Fury told Quake he was proud of her after the battle, but also that he wasn't the one who sent the alert. Daisy was once again reminded of the wheels within wheels involved in shadow ops, that no one was what they seemed, and even she would never know everything Nick was planning. [Secret Warriors (1st series) #2-6]
While Nick dealt with the higher-level planning, Daisy tried to keep her team in line. Their new recruit Eden Fesi was a teleporter who streamlined combat deployment. However, Sebastian Druid was not adopting quickly to covert life, making many mistakes in the field. J.T. James was a chronic complainer who got under Daisy's skin and had to be intimidated into backing down by 
Fury more than once. Alexander was a reincarnated Olympian god with a gift for prophecy. He once told Daisy that she would be one of the greats of their time, but would suffer considerably before-hand. His father, Ares God of War, served Norman Osborn's Avengers and followed Daisy and Alexander to their secret base once. Ares respected the training Fury was giving his son, though, and allowed it to continue, even though they might be on opposite sides. [Secret Warriors (1st series) #7-10, Dark Avengers (1st series) #9]
Stress built between Daisy and Nick as a third faction entered their secret war: Leviathan, a Soviet-era Russian organization that emerged from a period of “overwinter” to push back on the world stage. Daisy learned for the first time that her team of Caterpillars wasn't the only one -- Nick Fury had also been secretly fielding two more groups under his son Mikel and Alexander Goodwin Pierce for compartmentalized warfare.
At the meeting between the different teams, Nick also told Daisy to let Sebastian go, as he was 
becoming too much of a liability. Daisy stood up for her teammate and asked that he be given a second chance. Fury took it upon himself to ditch Sebastian prior to the team's next rendezvous, though, after telling Daisy it would be her decision. When Daisy found out, Nick told her it was only her decision if she was going to make the call he wanted. Frustrated with Fury's games, Daisy turned to J.T. James. J.T. hated Fury and his "mission,” and had recently confessed to Daisy that he only stuck around because of feelings for her. Quake decided to defy Nick by throwing herself into a relationship with J.T. [Secret Warriors (1st series) #11-16]
Quake and her team joined forces with Captain America and the Avengers to end Norman Osborn's reign over national security, but this did little to affect Nick Fury's private conflict. [Siege: Secret Warriors #1, Siege (1st series) #1-4] The war between Hydra, Leviathan and Nick's forces escalated on the world stage in a series of terrorist-level attacks and bombings on various assets in major population centers. Fury, Quake and the Secret Warriors prepared for a decapitation strike against Gehenna, the holy center of Hydra's nihilism world order. The strike was intended to be a 60 second drop with Eden's teleporting power, just long enough to attach a mountain breaker bomb to a key juncture and leave. However, Baron Strucker, Madame Hydra and Gorgon ambushed them at Gehenna, knocking out Eden before the escape plan could be enacted.
As the Secret Warriors fled to a secondary exit through underground caverns, Alexander stayed behind to cover their escape when the cavern bridge collapsed. Daisy and the Warriors watched from across the gap as Alexander fought the Gorgon in single combat, but lost and was killed by 
the former Hand grandmaster. Another horde of Hydra found them as they approached the extraction point, and this time Nick prepared to guard their retreat. Daisy objected, but J.T. offered to stay behind and support Nick while she got herself and the others to safety. The mountain breaker went off, burying Gehenna and leaving J.T. dangling over the side of the underground crevice. And so Fury... let him drop.
J.T. had been turned by Hydra, funneling them info in exchange for a promise to let him and Daisy go when it was all over. It was he who told Hydra about the mission to Gehenna and therefore he who was responsible for Alex's death and the High Council escaping. Daisy had gotten the rest of 
the team to their escape craft, piloted by Sebastian Druid, whom Fury had never really fired. Instead, Sebastian had been receiving one-on-one training until he was ready for the field again. When Nick arrived and told Daisy that J.T. didn't make it, she was distraught. And when Nick told her everything in the debrief, she collapsed under the weight of the betrayal and loss. The Caterpillar White Team was declared broken beyond repair. [Secret Warriors (1st series) #20-23]
Daisy retired to Hawaii with Sebastian for several months, recuperating physically and mentally 
from all she had gone through. In her absence, Nick Fury completed his work and orchestrated the downfall of Strucker and Leviathan. Before he disappeared from the public eye, he sent a message to Daisy apologizing (more or less) for how she had suffered. Nick had set into motion a scheme to revive S.H.I.E.L.D. through the United Nations security council, run by his old Howler buddy Senator Reb Ralston. Through Reb, Nick turned over the new S.H.I.E.L.D. to Daisy, leaving it in her hands to run how she saw fit, not just how he had taught her to run it. [Secret Warriors (1st series) #27-28]
