Mr Fantastic (Reed Richards) is the world's greatest scientist and leader of the Fantastic Four, able to stretch his body into any shape. Created by Stan Lee and Jack Kirby in 1961, Reed's intellect is his true superpower — he has built time machines, interdimensional portals, and devices to defeat cosmic entities. His greatest flaw is that same intellect: a cold rationality that often alienates those he loves. He is the architect of Marvel's scientific universe.
