Formation & Heroic Age
When Steve Rogers took over Norman Osborn's role as top cop, he chose not to continue H.A.M.M.E.R. nor to reestablish S.H.I.E.L.D. Instead, he decided to put the world's security into the hands of a few Avengers sub-teams. One of these teams became the Secret Avengers, and he took direct leadership of it with Sharon Carter assisting him with tactical operations. The purpose of this team was to covertly clean up the messes left by the Osborn administration. To this end, Steve personally recruited a team that would allow him to carry out surgical strikes in any given circumstance. This included experienced covert operators like Black Widow, Moon Knight and Ant-Man; a scientist in Beast; a one-man army in War Machine; a powerful magical warrior called the Valkyrie in Brunnhilde; and the cosmos' top cop Nova.
Steve's first go on a mission with the team to a mining facility of Roxxon Energy Corporation established on Mars. Some reports said that Roxxon had acquired the Serpent Crown, so Rogers decide to go to Mars with Black Widow and Valkyrie to find the artifact, which Beast later discovered that was not the real Serpent Crown, but a similar object. Rogers had also dispatched Nova to investigate on Mars and find more information, but he lost communication with him. The rest of the team went to Mars to find him and discovered he was being controlled by the entity of another artifact similar to the Serpent Crown. With the help of a being named Archon, who was charged to protect the world against the entity, they freed Nova.
Then, the Secret Avengers were confronted by Archon who wanted to kill Nova to be sure he would not be possessed by the artifact again. Nova left the team after Archon decide to let him live. They were also confronted by the Shadow Council, and for beat him, they have to deal with a Nick Fury imposter working for the Shadow Council. The real Fury confirmed that the imposter was an advanced Life Model Decoy modified by Jake Fury. He was going to destroy the LMD, but the Life Model Decoy was rescued by the Shadow Council and was named Max. Also operating in the "Shadow Council" were Aloysius Thorndrake and hero John Steele.
The planet named K'ai entered the solar system and was on a collision course with Earth. The Secret Avengers wanted Hulk to join them in a mission to intercept the planet as he was the only person on Earth who knew the planet and its culture. Hulk accepted it initially but when Skaar warned him against it, he refused to help the Avengers. The Secret Avengers asked Rick Jones if he would join the team who also turned him down. When the Secret Avengers left, the Hulk learned from Skaar that he has another son, Hiro-Kala, who is the king of K'ai leading this "attack" on Earth.
Hulk began a rampage in Cape Canaveral, trashing the spacecraft and equipment that was being prepared to intercept K'ai. The Secret Avengers arrived on the scene to battle the Hulk. After the team managed to subdue the behemoth, things only got worse when She-Hulk, Red She-Hulk, Skaar, A-Bomb and Korg arrived to aid Hulk in battle with the Avengers.
As a last ditch resort, Captain America threatened to have Black Widow and Moon Knight blast Hulk and his allies with a weapon that Iron Man had made as a last-ditch effort to counter future Hulk problems after World War Hulk, that would transport them all to the Negative Zone. The Hulk reverted to Bruce Banner and again refused Captain America's offer to join him in this mission, and instead he and his allies took control of the mission and left to deal with K'ai and Hiro-Kala by themselves.
The Secret Avengers were trying to help defend the nation during Fear Itself. While half of the Secret Avengers including Ant-Man, Beast, War Machine and the Prince of Orphans battled against Sin and her robots, the other half consisting of Commander Steve Rogers, Moon Knight, Black Widow and Valkyrie rushed to stop a person leaking government secrets to the public under Captain America's previous alias as the The Captain. Captain America finally locates The Captain just in time to stop him from uploading a video confession but he was too late to save several undercover assets and informants that were murdered by the organizations and syndicates they were infiltrating. As The Captain declares Steve a hypocrite for now doing the government's bidding, something that he previously rebelled against, as well as forming the Secret Avengers who only answer to him, Captain America gives him a beat-down. The Captain is arrested soon afterwards.
After the Captain is arrested, Beast is called away shortly to meet with the army because a member of the United States Congress who has locked himself in the House of Representatives wanted to meet him and refuses to evacuate the building despite that the building won't stand much longer. Leonard Gary, the revealed member of the United States Congress is a civil rights champion and old friend of Beast's who was revealed to be apparently responsible for making sure Senator Kelly's anti-mutant bills never made it. Beast meets with Gary to try to talk sense into him and get him to flee to safety. Gary refuses; showing Beast that when the evacuation came up, the House was still in session and he had the floor pushing a bill he'd been working on for eight years. The session was never officially called, so Gary's proposed health care bill was still officially on the table, so for that, Gary insisted upon staying. In the end, Beast leaves Gary behind to make his speech while he hacks into local news cameras to make sure the speech is given broad media coverage. Later in the speech, the building is heavily damaged and Gary is sadly presumably killed.
As the remaining Secret Avengers continued to try and defend Washington from Sin's blitzkrieg, one of the mystical war hammers from the Serpent crashed down in China ripping open the entrance to the Eighth City with its blazing trail of power. Prince of Orphans senses it immediately (as he is one of the Immortal Weapons) and he senses that hordes of demons flee out from the gate now opened by the hammer. Immediately, Prince of Orphans and War Machine leave the battlefield to investigate the matter in China, where they suddenly discover the villain Absorbing Man has arrived there to claim the weapon for himself. Then, Prince of Orphans and War Machine, allied with the rest of the Immortal Weapons including Iron Fist, fought against Absorbing Man and his wife Titania, both powered by two of the hammers. Meanwhile, the Black Widow began a quest personally to track down a group of journalists working for a muckraking tabloid who are wanting to post online about the death of the Widow's lover Bucky. She breaks into the offices, resulting is a lengthy meditation on the different meanings of the death of a superhero and the death of a normal person. The reporters agree not to publish the story as the public need to look up to the heroes instead of facing even superhuman's mortality.
After Steve Rogers became Captain America again, the roster changed drastically. The marksman Hawkeye was the new leader, along with the addition of the inter-dimensional hero Captain Britain, the symbiotic soldier Venom and the original android Human Torch. Meanwhile, Moon Knight, War Machine, and Sharon Carter left the team. Also Giant-Man helped to build the team's new base, the space station known as the Lighthouse. In a mission against the Descendants (a group of robots formed by the Father), Ant-Man seemingly died when saving a young boy, recently discovered to be a Descendant. In the end of the mission Human Torch was heavily damaged, but Ant-Man reappeared.
When the Phoenix Force was determined to be heading to Earth, a team of Avengers was assembled with Beast, Captain Britain, Valkyrie, Protector, War Machine, Vision, Ms. Marvel and Thor to go on a mission with the intent of stopping it before it reached the planet.
The Rise of the Descendants
After preventing the Shadow Council form using a three-part crown to fully unleash the mind-controlling Abyss, the Secret Avengers were attacked by the Descendants, who wanted to recover the Descendant child the heroes rescued, with the help of Ant-Man, revealed to be a Life Model Decoy working for Father. Meanwhile, Hawkeye, Beast and Captain Universe traveled to another universe to retrieve the Orb of Necromancy, the object Father used to create the Descendants.
The Descendants, with the addition of the Human Torch, reprogrammed to serve them, launched a massive attack on the main cities of the world, starting an invasion to take it and launched a nano-mist, which slowly started turning every human into a Descendant.
The Secret Avengers fought them, and the Human Torch, who Captain Britain made come into his senses, managed to destroy the Orb of Necromancy, which killed every single one of the Descendants of the High-Breed and eliminated the nano-mist from any human. Before dying, the Father told Captain Britain he still felt the presence of another Descendant who didn't die.
In the aftermath, the Secret Avengers reunited with Captain America to tell him what happened. Later, Hawkeye decided to disassemble the black ops unit.
