The Fantastic Four - History
Everything started with a (not very voluntary) mission into space. Reed Richards, Ben Grimm, Susan Storm and Johnny Storm were in the spaceship.
Their ship got destructed, and they were all exposed to a strange source of radiation, which should change their lifes forever...
The four members of the spaceship crashed to earth.
Johnny Storm was now capable to turn his body into a human flame...
Reed Richards could expand his body, like if it would be made out of some kind of gum!
Benjamin J. Grimm gained an extra portion of strenght, but his body turned into a rock!
While Susan Storm could turn herself invisible, and all the objects she touches. Also, she is able of creating something like a mental shield.
