Luke Cage possesses superhuman strength and stamina, and has extremely dense skin and muscle tissue which render him highly resistant to physical injury. Cage possesses these abilities as a result of a cellular regeneration experiment which fortified the various tissues of his body. His skin can resist high caliber bullets, puncture wounds, corrosives, and extreme temperatures and pressures without sustaining damage. A second exposure to said experiments further enhanced his strength and durability. The same experiment which granted him his great strength and durability has also given him a faster than normal recovery time from injury. Luke Cage is an exceptional street fighter and was a gifted athlete before receiving superhuman abilities.
