And usally Mr Fantastic solves Marvel Earths problems.Reed Richards’ powers are those of elasticity itself. He has complete mental control of seemingly every molecule in his body. He has been observed as being able to utilize his stretching form in a variety of offensive and defensive manners. He can twist or reshape his body or stretch roughly three miles, and as thin as a single molecule. Because of his elastic nature, Mr. Fantastic cannot be harmed by bullets or other projectile weapons, including knives, missiles, darts, etc, and all projectiles rebound to the attacker. Reed cannot be physically hit/cut, his skin simply reforms and “rolls with the punch”. Since obtaining his powers, Reed's blood has never been drawn. Not even Wolverine’s adamantium claws, nor Terrax’s Cosmic Powered Protonic Axe are able to pierce/wound Mr. Fantastic’s malleable body.
Reed can neither be grasped nor held, as his body can become slippery as an eel. However Reed is vulnerable to types of energy weapons. Reed can alter his physical makeup. He can, for instance, extend spikes from his body or make a giant fist, all of these feats can be performed within milliseconds. Another ability Reed has is that he can increase his size and mass density, which in turn increases his strength, in effect bulking his malleable body to “Thing” - like proportions, being almost as strong. Mr. Fantastic also has a degree of immunity to psychic attacks, his mind is as pliable and resilient as his body. Mind control is rarely effective on him. When it does work, it wears off sooner than it would a normal person.
Despite this, Richards' strength comes more from the powers of his mind than the powers of his body. He is the unquestioned supreme scientific intellect on the earth, his closest rival being the mind of Doctor Doom. Not only has Reed proven himself to be a genius in practically every science on earth, he has shown himself to be more knowledgable than even some of the most highly advanced alien civilizations in the known universe. He has been known to turn scraps of machinery into deadly weaponry within seconds. To say that his chosen code-name belies a sense of arrogance would be erroneous. In fact, to call the man fantastic would be nothing short of modesty.
