Mister Fantastic (Reed Richards) is a fictional superhero appearing in American comic books published by Marvel Comics. The character is a founding member of the Fantastic Four. Richards possesses a mastery of mechanical, aerospace and electrical engineering, chemistry, all levels of physics, and human and alien biology. He is the inventor of the spacecraft that was bombarded by cosmic radiation on its maiden voyage, granting the Fantastic Four their powers. Richards gained the ability to stretch his body into any shape he desires. Richards acts as the leader and father figure of the Fantastic Four, although in recent years he has increasingly been portrayed as being cold and distant towards his teammates due to his scientific, methodical nature. This is particularly true with his best friend, Ben Grimm, who partially blames Richards for his transformation into a large, rocky creature called the Thing. Whenever Richards is confronted with a challenge, his attention can be so focused that he can neglect even his own family. Regardless, he is the loving husband of Susan Storm, father of son Franklin Richards and daughter Valeria Richards, and mentor of his brother-in-law, Johnny Storm. He was first speculated, and later confirmed that he had diagnosed himself to be on the autistic spectrum.
