Sebastian Shaw

Kinetic energy absorption: Shaw has the superhuman ability to absorb kinetic energy and to metabolize 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 to 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.
 * Kinetic metabolism: Shaw can forgo sleep if he receives enough kinetic energy. Often, he will have his mercenaries pummel him to give him enough stored energy that he need not sleep for some time.
 * Enhanced durability: Shaw can still be crushed or cut but cuts are superficial because he saps the blade of all its thrusting/cutting energy. Shaw is adept at not letting enemies realize his power until they have hit him one too many times. Hitting Shaw is often described as "punching a mattress".
 * Enhanced strength: If properly energized, Shaw can lift and hold approximately one hundred times his weight. If bound, he can be punched by a teammate until he is strong enough to break the bonds. He is also adept at taunting foes into attacking him. Once, after being repeatedly hit by Piotr Rasputin, Shaw slapped both sides of Rasputin's head and his nose started to bleed.
 * Enhanced speed: When he has absorbed kinetic energy, Shaw's speed is increased. After absorbing enough energy, he can attack more quickly than opponents can react.
 * Enhanced stamina: Shaw's stamina is increased beyond normal human levels when he absorbs kinetic energy.
 * Regenerative healing factor: Shaw has healed from being hit repeatedly in the nose by Rasputin in less than an hour. However, his healing factor may not heal catastrophic injuries, such as a blast to the head or a broken neck.
 * Age reversal: Shaw's healing factor decelerates his aging process and restores most of his youth when he has absorbed energy, effectively making him immortal in a sense.
