Reed Richards gained the power of elasticity from irradiation by cosmic rays. He has the ability to convert his entire body into a highly malleable state at will, allowing him to stretch, deform, and reform himself into virtually any shape. Richards has been observed as being able to utilize his stretching form in a variety of offensive and defensive manners, such as compressing himself into a ball and ricocheting into enemies, flattening himself into a trampoline or a parachute to catch a falling teammate, or inflating himself into a life raft to aid in a water rescue. He can willfully reduce his body's cohesion until he reaches a fluid state, which can flow through minute openings or into tiny pipes. Reed is also able to shape his hands into hammer and mace style weapons, and concentrate his mass into his fists to increase their density and effectiveness as weapons.
