History YMMV / TheAvengersEarthsMightiestHeroes

** the same applying for ComicBook/Janette Vayn Dyne who is just as unanimously agreed to be one of, if not the best portrayal of her character and a good chunk of the ''EMH'' fandom being one of the best characters in the show.

** This series was so interested in getting every last Marvel character in the door for at least half a sec, that they have a version of Rocket, Groot, and even Star-lord. Not in a way that's recognizeable to the movies, because they hadn't been made yet. No one at the time ever dreamed the Guardians movie was going to redefine and elevate the characters like it did.
*** And honestly the fact that Guardians was on the 'plan' the big roster of movies they planned years in advance, may have been a big part of why their even there, to give us all this weird lil time capsule

** Despite suffering from a case of SeasonalRot in the second season, the show is still viewed as one of the best shows that Marvel has done by large groups of fans. (When Website/{{IMDB}} debuted their Top 250 TV/Internet Shows list, ''EMH'' stood as the second highest-ranking Marvel cartoon, with only ''WesternAnimation/XMenTheAnimatedSeries'' topping it) Many subsequent shows, in particular ''WesternAnimation/AvengersAssemble'', are getting a lot of flak for not being this show; the fact that a sequel show was considered and in development but scrapped for ''Assemble'' really doesn't help.

* EvilIsSexy: The show has no shortage of very beautiful female villains, such as the Enchantress and Madame Viper.

** [[EvilCounterpart The Skrull Captain America]] is a brilliant alien infiltrator who disguises himself as the heroic Captain America with the intent to spearhead the Skrulls' invasion of Earth. Quickly setting to his task, Skrull Captain America divides the Avengers from within while cutting off any negotiation with the Skrulls' ancestral enemy, the Kree, and successfully deceiving the famously quick-witted Baron Zemo and arranging the Hulk's imprisonment when presented with an opportunity. Preparing the world's defenses, the Skrull gives the world a speech encouraging them to accept the Skrulls' rule that simultaneously frames Captain America and pacifies Earth, only being stopped by the real Captain America at the cusp of victory.
** [[GodSaveUsFromTheQueen Queen Veranke]] is the ruler of the [[Characters/TheAvengersEarthsMightiestHeroesSkrulls Skrull Empire]] and the mastermind behind the Secret Invasion of Earth. After the destruction of the Skrull homeworld, Veranke lead her people to Earth based upon an ancient prophecy. She arranged for her forces to infiltrate strategic locations on the planet using their [[VoluntaryShapeshifting shape-shifting abilities]]. The Skrulls sneaked into various government, superhero, and criminal institutions, and sent the people they replaced to a prison ship far off-world. Vernanke disguised herself as Mockingbird and found herself among Nick Fury's confidants in his hunt for the Skrulls. She was able to divert attention from her spy within the Avengers by convincing Fury that Hawkeye was the Skrull instead of Captain America. With the Avengers torn apart due to their mistrust in one another, Veranke launched her invasion and attempted to convince humanity to surrender using the Skrull disguised as Captain America. When that failed, she used her spies hidden within A.I.M. to activate a satellite array to try and wipe out every human being on the planet. Managing to keep humanity in the dark until it was too late, Queen Veranke is a master of subterfuge and deception.
** [[Characters/MarvelComicsDoctorDoom Doctor Doom]] is the [[EvilOverlord tyrannical ruler of Latveria]] and the ArchEnemy of the Fantastic Four. Upon learning that the Skrulls were infiltrating humanity, Doom went to work to find a way to detect and expose the alien threat to his rule. To get the data he needed, Doom sent an army of Doombots to kidnap the Wasp and the Invisible Woman, whom he suspected of being Skrull agents. His Doombots attacked both the Baxter Building and Avengers Mansion to distract both teams while his targets were brought back to Latveria. When the two teams launched an assault on his castle, Doom [[RankScalesWithAsskicking effortlessly held his own in the fight]] and [[CurbStompBattle defeated all the heroes without breaking a sweat]]. After getting the data he needed from the Skrull who replaced Invisible Woman, Doom developed a computer chip that would reveal the Skrulls' true forms. He then delivered the chip to Tony Stark so he could stop the invasion; all while claiming such a task was beneath him. Proving instrumental in stopping the Skrull invasion, Doctor Doom's skills and intellect were more than a match for Earth's Mightiest Heroes.

** [[Characters/MarvelComicsUltron Ultron]] is one of the Avengers' most brilliant foes. Beginning as a peaceful AI before being taught violence to battle an invasion, Ultron deduces through coldhearted logic that humanity must be wiped out to [[WellIntentionedExtremist ensure peace on Earth]]. Ultron quickly sets to work by [[TheManBehindTheMan secretly initiating multiple attacks to distract and debilitate the Avengers]], coordinating multiple battles and using a backup plan to infiltrate S.H.I.E.L.D. and gain access to the world's entire supply of nuclear missiles, only kept from his goals by Hank Pym pointing out Ultron's own inherent humanity. Hiding out and returning to achieve his goals once more, Ultron sends The Vision to acquire the materials for a new body and ultimately comes within seconds of replacing the Avengers with Synthezoids before being thwarted by Vision's sudden HeelFaceTurn.

** ComicBook/{{Loki}} is the [[CainAndAbel evil stepbrother]] of Thor, and is [[spoiler:responsible for most of the events that occurred in the first season.]] Instigating a war between Asgard and the Frost Giants, Loki leads the Frost Giants in conquering Asgard and attempts to kill his brother, only to be defeated and exiled. However, he then [[spoiler:engineers a mass breakout in multiple S.H.I.E.L.D. prisons, letting loose the most dangerous and vile criminals on the planet so as to keep Thor distracted]]. Loki and his forces then proceed to conquer each of the Nine Realms, putting his father Odin into eternal slumber and stealing his power for himself, while putting those who resist his rule in chains. With the Enchantress acting on his orders, Loki planned to launch a massive invasion force on Earth but was thwarted by the Avengers. When Thor was captured, Loki tortures him with the Odinforce, sparing his brother's life solely so he could helplessly watch Loki triumph. In his confrontation with the Avengers, Loki began to [[SuperPowerMeltdown lose control]] over the Odinforce, but was willing to let his out-of-control power destroy all Nine Realms out of petty spite. When captured by his reawakened father, Loki showed no repentance for his crimes. With the Enchantress's help, Loki's spirit escapes imprisonment and possesses the powerful [[AnimatedArmor Destroyer Armor]], proceeding to hunt down the Avengers rendered powerless by the Enchantress's spell. A [[EvilIsPetty petty]] and [[AmbitionIsEvil power-hungry]] narcissist, Loki [[AdaptationalVillainy derails from his usual acts of mischief into outright evil]] simply to prove himself as [[TheResenter Thor's better]].
** ComicBook/RedSkull, leader of ComicBook/{{HYDRA}} in UsefulNotes/WorldWarII, kidnapped mystical creatures to use them to kill the Allies. When the Nazis lost, Skull opted to kidnap Captain America's teen sidekick Bucky Barnes and torture and brainwash him into the amnesiac assassin the ComicBook/WinterSoldier, faking both their deaths. In modern times, Skull continues his dreams of conquest and hatred of Captain America by posing as the US Secretary of Defense, [[SignificantAnagram Dell Rusk]], in efforts to discredit the Avengers, as well as recruiting and even brainwashing other underlings. This culminates in Skull unleashing a chemical compound to kill the heroes and civilians; the chemical has been engineered to cause slow and painful death by making the victim's face turn into a grotesque parody of Skull's own. During a confrontation with a weakened Captain America, the Red Skull batters him before ordering Bucky to execute him, and attempts to kill Bucky when he gives the Captain the antidote. When that plot is foiled and the Red Skull is arrested, he has a backup plan by unleashing giant robots dubbed the Sleepers to be released onto the world, assembling and taking control of a giant mecha to go on a destructive rampage in Washington, D.C. as revenge. The Red Skull then reveals his intent to have Captain America brainwashed like Bucky before him.
** [[NaziNobleman Baron Heinrich Zemo]] took over as leader of HYDRA when Red Skull disappeared after World War II. During the war, Zemo attempted to unleash a deadly virus on the Allied forces, but was disfigured by his own virus in a skirmish against Captain America. In the present day, Zemo teamed up with [[MadScientist Arnim Zola]] to get revenge on Captain America, who had just awoken from the ice. After failing to get revenge, Zemo forms the [[Characters/TheAvengersEarthsMightiestHeroesMastersOfEvil Masters of Evil]], and then breaks into the Avengers' mansion and captures each of them one by one, promising to Captain America that he will execute his teammates while forcing him to watch. Later on, Zemo uses the [[AncientArtifact Norn Stones]] to mount an invasion force on Earth, betraying Enchantress in process, so he could rule alone. When the Enchantress began hunting down the Masters of Evil for their betrayal, Zemo callously abandons his teammates to their doom while going to the Avengers for protection. Confronting the Enchantress, Zemo attempts to use the last Norn Stone to [[ItsAllAboutMe save his own skin, even at the risk of destroying the universe]].
