Avengers

The group began with the random teaming of Thor, Iron Man, Ant-Man, Wasp and Hulk, who joined forces to thwart the Asgardian menace Loki in response to a call for help from Hulk's teen sidekick, Rick Jones. Pym suggested the heroes remain together as a team, and his partner Wasp suggested they call themselves "something colorful and dramatic, like...the Avengers." The name stuck, and a legend was born.

Iron Man provided the group with financing and high-tech equipment in his dual identity as rich industrialist Tony Stark, donating his Manhattan residence to serve as their headquarters, Avengers Mansion. Stark's butler, Edwin Jarvis, stayed on as the mansion's principal servant and chief of staff, becoming a valued friend, confidant and advisor to the group. Stark also drew up a charter and by-laws to guide the team, and sought A-1 security clearance from the federal government, but he encountered resistance from the team's first National Security Council liaison, Special Agent Murch, and the general public regarded the new team somewhat uneasily. Much of this early skepticism focused on the monstrous Hulk, who soon quit the team in a fit of rage, but the group's image improved dramatically after they recruited long-lost war hero Captain America, who became the inspirational cornerstone of the Avengers. Thanks largely to his presence, the team won its A-1 security status and rapidly became the most respected super-hero team of its generation. This newfound prestige was sorely tested when the remaining founders retired from active duty for various personal reasons, leaving "Cap" alone to lead a roster of unlikely new recruits, all former criminals: the outlaw archer Hawkeye, and mutant terrorist twin siblings Quicksilver and the Scarlet Witch. The public was baffled, but Iron Man hoped that rehabilitating them might make up for the team's early failure with the Hulk. The new roster proved him right, and "Cap's Kooky Quartet" did the founders proud. All four of them went on to long service records with the Avengers. Hawkeye in particular became a valued mainstay of the team second only to his mentor, Cap.

The group's expansion accelerated after they opened a second headquarters on the West Coast, Avengers Compound, manned by both Avengers veterans and new recruits like Hawkeye's wife Mockingbird, War Machine (who also served as an alternate Iron Man), Thing, Moon Knight, U.S.Agent, Firebird, Human Torch, Living Lightning, Julia Carpenter as Spider-Woman, Machine Man, and Darkhawk. The western roster was led first and longest by Hawkeye, but the expansion team gradually deteriorated under later leaders and was shut down after major losses of resources and personnel. Regardless, the original eastern roster continued to grow, adding recruits such as Sub-Mariner, Doctor Druid, The Captain (actually a temporarily re-costumed Captain America), Demolition Man, Gilgamesh, Mister Fantastic, Invisible Woman, Quasar, Sersi, Spider-Man, Stingray, Rage, Sandman, Crystal, Thunderstrike (who also served as an alternate Thor), Justice, Firestar, Triathlon, Silverclaw, the new Ant-Man and Captain Britain. Some of these served long stints, others only briefly, but all made some sort of mark with the team, as did more informal associates such as Marrina, a new Yellowjacket (Rita DeMara), a new Swordsman (Phillip Jarvert), Magdalene, Deathcry, Masque, and an alternate-timeline teenage Iron Man.

The group suffered setbacks, going through many changes of leadership and several changes of headquarters, losing various members and even disbanding more than once (most notably following disastrous conflicts with Terminatrix and Onslaught), but the team always regrouped in some form or another, continuing to evolve and grow. Few heroes refused offers of Avengers membership, though allies who did decline the honor included Daredevil, Jessica Jones, Spider-Woman, Silver Surfer, Archangel, Iceman, Dazzler, Black Cat, Doc Samson, Shroud and Songbird.

It required a threat from within to ultimately vanquish the original Avengers. The Scarlet Witch, whose mind had slowly been damaged by her reality-altering powers, caused a series of events which resulted in the apparent deaths of Hawkeye, Vision, Jack-of-Hearts and Ant-Man. The Avengers Mansion was completely destroyed, and Tony Stark's fortune was, at the time, too depleted to rebuild, and the remaining members disbanded.

Months later, much like the original inception of the team, a random gathering of heroes sparked the reformation of the Avengers. After teaming with Iron Man, Spider-Man, Luke Cage, Spider-Woman (Drew), Daredevil and Sentry to contain a mass breakout at the super-criminal prison known as the Raft, Captain America invited his six allies to join him in rebuilding the Avengers. Most of them accepted, though Daredevil declined and the unstable Sentry had gone into seclusion. Leading intelligence agency S.H.I.E.L.D. was reluctant to sanction a new Avengers team, but Captain America reminded them that his "full champion license" status with the government gives him the authority to assemble any team he requires for any given mission, so he required no approval from the authorities to reassemble the Avengers. Iron Man offered the top floors of his new Stark Tower skyscraper to serve as the team's high-tech headquarters (staffed again by ever-faithful Jarvis), and the group resolved to capture the forty-odd Raft escapees-starting with Sauron, the prisoner whose liberation by Electro had touched off the jailbreak.

Capturing Electro and tracking Sauron to the Savage Land, the new Avengers teamed with Wolverine to oppose an illegal Vibranium mining operation run by Sauron's Savage Land Mutates and an apparently rogue S.H.I.E.L.D. faction. In the end, a retaliatory strike by the mainstream S.H.I.E.L.D. organization wiped out the entire mining operation except for a recaptured Sauron, conveniently eliminating almost all evidence and witnesses apart from the Avengers. Shaken by this, and by their discovery along the way that the Raft had been stockpiling supposedly deceased super-criminals held in reserve for unknown purposes, the Avengers have secretly dedicated themselves to rooting out the institutional corruption behind these events and have recruited Wolverine, whose espionage background and ruthless attitude are seen as assets for the team.

Realizing the potential danger of a loose canon Sentry, Iron Man held a secret conclave with the Illuminati and organized a large team to track down the hero. The Sentry warned the Avengers of his alter ego, the Void, who assaulted the Avengers and the other heroes. With the help of Emma Frost, the Sentry gained control of the Void. The Sentry accepted membership into the Avengers, which they hoped would prevent him becoming another Scarlet Witch situation. Returning to Stark Tower, the Avengers were stunned to find the Sentry's Watchtower located directly above theirs.

Tracking down the Silver Samurai (one of the escaped criminals from the Raft) to Japan with the help of Ronin, the Avengers found Hydra trying to strike a deal with the Hand and Clan Yashida. After defeating the forces of the Hand and Hydra, the Avengers confronted the Silver Samurai, who planned to stay in Japan to serve as a protector. Ronin returned to Japan to make sure that Samurai stayed out of trouble. Shortly after leaving, Spider-Woman freed Madame Hydra and accidentally nearly killed Captain America. When the Avengers interrogated her, she revealed that long before the Avengers had recruited her, she had lost her powers. Hydra approached her with the chance to regain her abilities provided she become a double agent for them in S.H.I.E.L.D. When Nick Fury learned this, he agreed to reinstate Spider-Woman into S.H.I.E.L.D. provided that she play a double agent for him. Spider-Woman regained her powers and things went smoothly until Nick Fury went underground and left Spider-Woman with no one to trust. The Avengers realized the situation, but before they could act, they were forced to go public since the Watchtower had alerted the public to their presence.
