Marvel: Kinetic Energy Absorption

Guido Carosella (Strong Guy)
Strong Guy has the ability to absorb kinetic energy and use it to enhance his physical strength to above normal limits. However, he cannot store the energy he absorbs for very long; as a rule, he must expend it within 90 seconds to prevent the enormous amounts of energy from permanently distorting his body. He is constant pain from the existing distortion, although he hides it well, traditionally playing the role of team comedian to distract himself. An unusual percentage of his body mass is stored in the upper-half of his body, causing him to appear top-heavy, imposing, and somewhat comical.

Sebastian Shaw
Sebastian Shaw is a mutant with the superhuman ability to absorb kinetic energy and to metabolie it to enhance his own physical strength, speed, and stamina. This makes him extremely difficult to defeat in battle, as every blow struck against him only makes him stronger. Unusual tactics are required to defeat him, usually by incapacitating him or by attacking him psionically. Shaw absorbs the energy of any blow he is struck by, not just punches, but also projectiles like bullets and, to a less successful degree, electricity and physically-based energy beams. Without absorbing energy, Shaw is merely a strong ordinary human, though, normally, he works to keep his strength at a superhuman level. For example, in one instance, he was shown to spend time hitting a wall after waking in order to build up his power reserves. It is revealed in his encounter with Hercules and Madison Jeffries that his power of energy absorption is not limited to kinetic energy and that he can absorb any form of energy to fuel his powers. According to Shaw, kinetic energy just works the best.
