History YMMV / FantasticFourWorldsGreatestHeroes

** [[Characters/MarvelComicsDoctorDoom Doctor Doom]], the ArchEnemy of the Fantastic Four, [[AdaptationalVillainy lacks the redeeming qualities of his original comic counterpart]]. [[CreateYourOwnHero Responsible for the incident that led to Fantastic Four getting their powers]], Doom later switched bodies with Reed Richards to ruin his reputation, to the point of deciding to overload the power core of Fantastic Four's base to destroy everything within several city blocks. Afterwards [[FrameUp framing Reed]] for supposedly "experimenting on his friends", Doom tried to use his inventions to unleash the energy of the Negative Zone upon New York, which threatened to kill thousands. In his most ambitious scheme, Doom stole Annihilus's power source and brought it to Earth, threatening to destroy the entire universe, solely so he could use it to conquer and destroy everything he sees. Despite losing the way of controlling the power source, Doom still clung to it, not caring that it was close to wiping out all life in the cosmos.

* BadassDecay: ''Doom'', seriously, in the first few episodes, he's quite the legitimate threat who could kick your ass without a second thought, but, in later episodes...

* NightmareFuel: The Negative Zone, and Annihilus himself in “Annihilation”. The show may be LighterAndSofter, but he’s an AxCrazy KnightOfCerberus, and the episode is one of the creepiest in the series.

** [[MoleMen Mole Man]] is the short hideous man who resented "pretty people" for looking down upon him. Building his base underground, Mole Man created "Moloids", whose sole purpose was to serve him. Regularly plotting to destroy "the surface world", Mole Man tried to take control over the army of monsters, so he could lead them to [[KillAllHumans wipe out humanity]]. After being thwarted, Mole Man created a device, which he planned to use to erupt all volcanoes on Earth, fully ready to destroy all life on the surface of the planet for petty revenge.

* HilariousInHindsight: In "My Neighbor Was A Skrull", most of the Skrulls who interact with the Four are disguised as elderly humans. In ''{{Film/Captain Marvel|2019}}'', the titular character chases and fights a Skrull disguised as an elderly human woman.

* IronWoobie: Ben Grimm, like his comic counterpart, just wants to be human again. Every time he came close, he ended up losing it. First was changing him from a molecular level, but that erased his memories and his amnesiac self was fine getting turned back into The Thing to save his friends. The second time was when he and Reed switched powers, and Reed was fine with it despite the setbacks since it was the closest to a cure Ben could get, but Ben rejected the idea to save his friends. It's a miracle he hasn't gone crazy.
* MoralEventHorizon: Doom has two moments. The first is in "Doomsday" where he opens a portal to the Negative Zone to unleash monsters and unstable energy from the dimension into New York and make it look like Reed caused it. The second is when he [[spoiler: kills Reed in "Out of Time". Though Reed is brought back after time is properly reset.]]

* HilariousInHindsight: In "My Neighbor Was A Skrull", three Skrulls who interact with the Four are disguised as elderly humans. In ''{{Film/Captain Marvel|2019}}'', the titular character chases and fights a Skrull disguised as an elderly human woman.

* HilariousInHindsight: In "My Neighbor Was A Skrull", the two Skrulls who interact with the Four the most are disguised as elderly humans. In ''{{Film/Captain Marvel|2019}}'', the titular character chases and fights a Skrull disguised as an elderly human woman.

* BestKnownForFanservice: Most people will remember this as the series that gave Susan Storm a ''very'' good figure, complete with shots of her rear.

* AwesomeArt: One thing that cannot be complained about with this series is the animation. All of the characters are well designed and {{Animesque}}, with the fight scenes done excellently.

* OneSceneWonder: SquirrelGirl

* VillainDecay: ''Doom'', seriously, in the first few episodes, he's quite the legitimate threat who could kick your ass without a second thought, but, in later episodes...

* UnfortunateImplications: Why is it that Alicia Masters getting a RaceLift means that her Stepfather has a RaceLift as well.
** Because they make it pretty clear that he's her ''biological'' father in this version.

** He will still kick your ass, sometimes even off screen.

* DullSurprise: Reed's voice just sounds uninterested in anything going on.

* YourMileageMayVary: This is the FF either at their finest or at their worst, it all depends which fans you ask.
