"A team-- and family-- of adventurers, explorers and imaginauts, the Fantastic Four lead lives both ordinary-- and extraordinary."

Where other teams are in the Marvel universe are, ultimately, simply collections of heroes or villains, the Fantastic Four are a family, a bond that is hard to match by any other coupling of characters. While the line-up has changed from time to time, the Fantastic Four are defined by a core: Mr. Fantastic, the Invisible Woman, the Thing and the Human Torch. In the Marvel RPG, this is no different.

Current members:

• Mister Fantastic (Reed Richards) - SuperFerret
• Invisible Woman (Susan Richards-Storm) - NPC
• Human Torch (Johnny Storm) - Spider-Man9X17
• The Thing (Ben Grimm) - NPC
  

Season I - Mr. Fantastic, the Invisible Woman, the Thing and the Human Torch
In the wake of the superhero bounty, and an attack by Magneto orchestrated by their greatest enemy, Victor Von Doom, the Fantastic Four decide that Earth is not a safe place for Franklin and Valeria Richards, children of Mr. Fantastic and The Invisible Woman. On what is to be a routine trip to the moon to place the children in the care of the Inhumans, The Fantastic Four are inexplicable transported through time and space to a far off galaxy, ending up on the planet Kryptron. At first treated as hostile intruders, the quartet is soon welcomed as guest by Kryptionian elder and chief scientist Jor-El.

After brief introductions, Reed and Jor-El set to work on a plan to return the Fantastic Four back to Earth. The quartet learns that because of a rocket accident years before, the Kryptonian space program has been shut down. Deciding the teleportation is out of the question since in too unreliable and unpredictable, the two scientists decide they have no choice but to work quickly under the veil of secrecy to construct a spaceship to return the Fantastic Four to Earth. The meeting is interrupted by General Zod, head of Krypton's military and rival of Jor-El. Zod blackmails Jor-El, forcing him to agree to turn over any plans he and Reed draw up, or Zod will turn them all over to Krypton's ruling council. Johnny steps in to stand up for Reed, and rather than push the confrontation further, Zod steps down, reminding Jor-El of the consequences of any non-compliance.

Reed runs some quick calculations, and determines that Kryptonian soil, combined with the advanced crystal technology and ignited by the intense heat of the Human Torch's nova flame, will turn radioactive and burn hot enough to power the ship through time and space and return the group home. Reed and Jor-El get to work, while Johnny begins a romantic, though secret, relationship with a Kryptonian woman named Shara-Za.
