Season 1
Most episodes in the first season consisted of fairly accurate re-interpretations of classic 1960s Fantastic Four comic book stories by Stan Lee and Jack Kirby. For instance, this series stayed true to the original comic book story that recounted the Silver Surfer and Galactus' coming to Earth in a two-part episode as well as Doctor Doom's theft of the Surfer's powers. [6] [7] However, the season's cost-effective animation (provided by Wang Film Productions and Kennedy Cartoons) and attempts to add humor through the inclusion of a fussy British landlady (portrayed by Lee's wife Joan) for the Fantastic Four were generally met with displeasure by fans – to say nothing of then-current Fantastic Four comic book writer Tom DeFalco, who got in trouble for penning a scene in issue #396 of the series that featured Ant-Man watching and lambasting an episode of the cartoon.

It's also the only season to use digital ink and paint in some episodes.
In the two-part premiere "The Origin of the Fantastic Four", Puppet Master took control of the Thing and used him to capture Invisible Woman. Mister Fantastic freed the Thing from his control and defeated the Puppet Master. Upon returning to his apartment to reclaim his final doll, he ended up in a fight with Alicia Masters, and then he apparently fell to his death from the apartment window. The Fantastic Four weren't able to find his body and claimed that he "vanished from Earth."
In "The Silver Surfer & the Coming of Galactus", the Silver Surfer, Firelord, and Terrax fight the Fantastic Four while Galactus attempts to feed on Earth. By season 2 however, all but the presence of Silver Surfer in that battle is ignored as Terrax is seen again and referred to as being the replacement for the Silver Surfer. In the episode "When Calls Galactus", Terrax is killed/turned into a worm and Nova (Frankie Raye) becomes the new herald of Galatcus.
In the three-part special episode, "Mask of Doom", Doctor Doom captures the Fantastic Four and forces Mister Fantastic, Human Torch, and the Thing to go back in time and obtain an object for him. In the aforementioned episode "Silver Surfer and the Return of Galactus", Doom steals the Silver Surfer's powers and tries to steal Galactus' powers, only to be thwarted by the planet devourer himself.
Season 2
Both the Fantastic Four and Iron Man series were radically retooled for its second and final season, sporting brand-new opening sequences, improved animation (as previously mentioned, the animation for the first season thirteen episodes was done by Wang Film Productions and Kennedy Cartoons, while the second season's animation was provided by the Philippine Animation Studio), and more mature writing (the first season was primarily written by Ron Friedman, while the second season was overseen by Tom Tataranowicz), though noticeably having fewer introductions by Stan Lee, with several of the new shorter intros being used more than once. Not only that, Four Freedoms Plaza replaced the Baxter Building as the Fantastic Four's home base in season 2. The season 2 episodes also drew upon John Byrne’s 1980s run on the Fantastic Four comic (as well as John Buscema's artwork), in addition to further Lee and Kirby adventures.
In the second season's premiere episode "And a Blind Man Shall Lead Them" (guest starring Daredevil), Doctor Doom strikes at a now fully powerless Fantastic Four and has his hand crushed by the Thing. Doom next appears in "Nightmare in Green", where he directs Hulk to attack the team.
Wizard appears in the episode "And the Wind Cries Medusa" (Part One of the three-part Inhumans Saga). In his debut appearance, he assembles Medusa, Hydro-Man, and Trapster to form the Frightful Four. On a related note, this episode aired one week from Hydro-Man's debut appearance in Spider-Man . Wizard also used a device to control the Thing. Meanwhile, Crystal, along with the other Inhumans Black Bolt, Gorgon, Karnak, and Lockjaw, also make their debut in the three-part "Inhumans Saga" episode. After escaping the Negative Barrier, Crystal goes on to become the girlfriend of the Human Torch. Seeker appears in the episode "Inhumans Saga: Beware the Hidden Land". He is sent by Maximus the Mad to retrieve the Inhuman Royal Family. After saving the Fantastic Four from the explosion, Seeker briefly shares the history of the Inhumans to them.
Susan Richards as Malice appears in the episode "Worlds Within Worlds". Malice's appearance is the result of Psycho-Man using his empathic abilities to make Susan turn against her Fantastic Four teammates. Eventually, Susan is freed of Psycho-Man's influence and defeats him.
The Black Panther appears in the "Prey of the Black Panther". He lures the Fantastic Four to Wakanda to see if they are worthy enough to help fight Klaw. As in the comics, Klaw's history of killing T'Chaka is included as well as T'Challa using Klaw's own weapon on his right hand.
In "To Battle the Living Planet," the Fantastic Four ask Galactus' help in confronting Ego the Living Planet. Thor meanwhile guest stars in two episodes. In "To Battle the Living Planet," the Fantastic Four help him fight Ego the Living Planet even when they enlist Galactus' help. In "When Calls Galactus," he and Ghost Rider (he uses the penance stare, so it is more likely it is the Daniel Ketch version instead of the Johnny Blaze version) both help the Fantastic Four fight Galactus. Also in "When Calls Galactus", Nova volunteers to replace the treacherous Terrax as Galactus' herald. As in the comics, Frankie Raye ends up getting her powers when she is accidentally doused in the chemicals that gave the android Human Torch his powers.
Franklin Storm appears in the episode "Behold, A Distant Star". Just like in the comics, Franklin Storm lost his wife in an accident, and an altercation with a loan shark led to an accidental murder. When Invisible Woman has shrapnel in the lower part of her brain after a recent Skrull attack (Lyja is shown as a commander to the Skrull army), he has to come out of hiding to perform the surgery. He turns himself over to the arriving police. After being freed from his volcanic prison, Super-Skrull replaces him in prison and takes on the guise of the Invincible Man, who breaks out of prison, goes on a rampage on the city, and runs afoul of the Fantastic Four. They soon realize that Franklin Storm is Super-Skrull in disguise. Warlord Morrat has a concussive energy beam projector attached to Dr. Storm's chest. The projector is set to go off the moment he sees the Fantastic Four. When Storm appears, he warns the Fantastic Four to stay away and rolls over on the floor, taking the full force of the deadly concussive blast.
In "Hopelessly Impossible", Lockjaw helps the Human Torch get the Impossible Man to The Great Refuge and away from the Super-Skrull.
In what turned out to be the series finale, "Doomsday", Doctor Doom acquires the almighty Power Cosmic. He once again tries to go after Galactus, only to hit the barrier that prevents the Silver Surfer from leaving Earth.
The Incredible Hulk crossover
Simon Templeman reprised his role of Doctor Doom for guest appearances in two episodes, in which Doom held Washington, D.C. captive, only to be defeated by She-Hulk, whom he later attempted to claim revenge upon. With his appearance on this show, it can be assumed that Doom survived the fate he met on the Fantastic Four series, if both shows are to be considered within the same continuity.
Following Doctor Doom's first appearance (he appears again in the second-season episode "Hollywood Rocks"), comes the episode "Fantastic Fortitude" featuring his nemesis, the Fantastic Four. The episode seems to place this show in the same continuity with the Fantastic Four cartoon of the same decade, as this episode plays off the Hulk's appearance in the other show. More to the point, Beau Weaver (Reed Richards/Mister Fantastic) and Chuck McCann (Ben Grimm/The Thing) reprise their roles from the Fantastic Four series. In the episode, Mister Fantastic and the other Fantastic Four take their vacation prior to Hulk, She-Hulk, and Thing fighting Leader's Gamma Soldiers. Meanwhile, She-Hulk flirts with Thing, but Ben chooses to rekindle his relationship with Alicia Masters. While the Yancy Street Gang never appear in the solo Fantastic Four cartoon itself, they appear in "Fantastic Fortitude", where they pull a prank on the Thing. After being defeated by the villain Ogress, the Gang, always off camera, distributes leaflets marked "THING WHUPPED BY A WOMAN!", much to Thing's chagrin.
