Created by Stan Lee and Jack Kirby in 1961, the Fantastic Four are Marvel's First Family and the superheroes who started it all. They came before Spider-Man, the X-Men, and even The Avengers, and while the team hasn't retained the A-List status they had in the 1960s, their importance in Marvel history can not (and should not) be ignored by any comic book fan. After a trip into outer space which saw them bombarded by cosmic rays, the Four returned to Earth with extraordinary abilities. Ever since then, Mister Fantastic, The Invisible Woman, The Human Torch, and The Thing have been a mainstay of the Marvel Universe, and they've saved the Earth - and even the entire universe - on a number of occasions. The team may not have a long list of classic storylines, but their comic series has introduced countless iconic villains, including Annihilus, Doctor Doom, and, of course, Galactus. It's not just the Fantastic Four's villains who are great though - Reed, Sue, Johnny, and Ben are no doubt four of the bravest and most instantly recognisable superheroes of all-time. They've starred in cartoons, two (terrible) live-action movies, and will get another chance at big screen success with a reboot from director Josh Trank a little later this summer. If that goes well, expect to see the Fantastic Four step back into the spotlight in a big way. Here, you'll find just twenty of the most mind blowing facts about the Fantastic Four. Whether it's the truth about what's really in The Thing's pants after his rocky transformation, the downside to tricking a Skrull into becoming a cow, or Bill Murray's surprising connection to the team, these will undoubtedly change your perception of the foursome!
