[[caption-width-right:350:The Avengers and some fans...]]
The second Avengers team was created in ''Avengers'' #17. Stan Lee wanted to get rid of the similarity with the Franchise/{{Justice League|of America}}, and removed Thor, Iron Man, Giant Man and the Wasp from the team, all of them with their own comic books, and replaced them with Hawkeye, Quicksilver and the Scarlet Witch. Captain America stayed, hence this incarnation became known as "Cap's Kooky Quartet". They had minor powers in comparison, and the three new members were former super villains: Hawkeye from Iron Man, and the others from the X-Men.

The series also introduced Jarvis, the Swordsman, the first Power Man (Erik Josten, who would later become known as Atlas; not Luke Cage) and Kang's lover Ravonna, among others.

!!The second Avengers team contains examples of:
%% PLEASE read ExampleIndentationInTropeLists
* AncientAstronauts: The minotaur
* BadassMustache: The Swordsman. There's even a close-up panel of it.
* BadassNormal: Cap and Hawkeye.
* BolivianArmyEnding: The end of the adventure with Kang. The Avengers, taken to the 30th century, were allowed to return to their original timeline. They were in the machine, already vanishing, when Captain America warned Kang that the assassin Baltag was [[RightBehindMe right behind him]]. He fired at Kang, Ravonna took the bullet, Baltag was executed right away... and the Avengers returned to the 20th century, without knowing (for several months, at least) if Ravonna had died saving Kang or not.
* BruceWayneHeldHostage: Attuma captured the Wasp, but she was not wearing the mask or the costume, so he did not suspect anything (and she still had a secret identity at the time).
* CaptainSuperhero: Captain America began to fit this role. In the previous team, he was just one among the others.
* ChuckCunninghamSyndrome: Rick Jones and his "teen brigade". He is seen in the first issue, upset because he'd been waiting to become an Avenger for some months to no avail, and those three guys became Avengers just like that. He was not seen again in the Avengers until the Kree-Skrull War, several years later.
* DamselOutOfDistress: The commissar captured the Scarlet Witch and held her hostage, while forcing the Avengers to fight against him. Captain America, Hawkeye and Quicksilver were all defeated. And then... Captain America asked him to free the Scarlet Witch and fight her as well. Being a [[DirtyCommunists Dirty Communist]], he WouldHitAGirl. But she defeated the commissar all by herself... [[spoiler:by proving that it was ActuallyADoombot]].
* EvilMentor: The Swordsman trained Hawkeye in his youth.
* TheGeneralissimo: The commissar, a [[DirtyCommunists Dirty Communist]].
* HeelFaceTurn: The first case in the Avengers. Actually, they were not much "evil" to begin with: Hawkeye was mistaken as a villain, and Quicksilver and the Scarlet Witch were blackmailed by Magneto to work in his Brotherhood of Evil Mutants, and left it at the first chance they got. Still, their villainous past would be mentioned several times over the years (a notable example was when the ComicBook/{{Thunderbolts}} appeared) and opened the path for several other former villains who would become Avengers.
** It also counts for the Swordsman, at the end of the story.
* HumongousMecha: Which enemy do they fight first? Of course, the classic giant robot.
* ImprobableAimingSkills: With Hawkeye in the team, the Avengers began to use a lot of this.
* LatexPerfection: Captain America, costumed as a business agent, claimed to Power Man that he had arranged the breakup of the Avengers, so he made an AccidentalConfession. And he had a latex mask... over his Captain America's mask.
* LeaderWannabe: Hawkeye. He says that he would be a better leader... 3 or 4 times an issue.
* LoveRedeems: Kang has launched the full force of his countless armies against the petty little nation of Ravonna. How can the Avengers, without the armoured power of Iron Man, the immortal stamina of Thor, or the titanic strength of Giant Man, fight against the most powerful army ever? What about with ThePowerOfLove?
* MookPromotion: Erik Josten, an unknown mook of Baron Zemo, left on his own wandering in the jungle after Zemo's death. He used the machine that created Wonder Man, becoming Power Man (not ''that'' Power Man, in fact he fought with Luke Cage for the right to the name, and lost). Years later, he got size-changing power. Then, ionic powers. Then, he became the superhero Atlas of the ComicBook/{{Thunderbolts}}, and the rest, as they say, is history. Not bad for a mere unnamed mook.
* ScrewTheRulesIMakeThem: Kang loves Ravonna, and after conquering her city he orders to prepare a royal wedding. Kang's lieutenant reminded him of the rules: the deposed royals must be executed immediately, to prevent rebellions. But Kang himself designed that law, and his rule is absolute: so screw the rules!
* SingleStrokeBattle: Captain America retired from the Avengers, and began a boxing career. But when he heard in the radio that the Avengers were captured by Kang, he gave it up and returned to help. Problem is, the champion did not allow him to interrupt the fight just like that... so Steve Rogers took him down with a single megaton punch.
* SurveillanceAsThePlotDemands: Kang, Mandarin, Dr. Doom...
* StormingTheCastle: Justified in-story. When he refused to execute Ravonna, Kang's army turned against him. Alone against a whole army, he freed the Avengers and some other prisoners to save Ravonna. The army was powerful, but the poor leadership of Baltag had it in chaotic disarray, while Kang's band was small, but led by the greatest military genius of all history (so says Stan Lee... and not talking about Cap precisely), and managed to find their way to Baltag himself.
* TakingTheBullet: And a really romantic case. Ravonna took the bullet fired to Kang when she realized she actually loved him.
* WaterIsAir: Averted in the battle against Attuma. The complications of fighting underwater, which slows speed and reflexes, and the problems with pressure, are fully acknowledged in the plot.
* WithAFootOnTheBus: Power Man and the Enchantress managed to turn the Avengers into [[HeroWithBadPublicity heroes with bad publicity]]. Captain America managed to clear their names; and then retired. He gave up his Captain America identity, and started a new life as a boxer... which lasted for just a few pages. When he heard on the radio that the Avengers had been kidnapped by Kang, [[AchillesInHisTent he took up the shield again and headed to the battle without a second thought]].
