As a result of the treatment, Carl’s skin became unbreakable, and his strength was amplified to superhuman levels. Now bulletproof and able to punch through four-inch-thick steel, Carl took on the name Luke Cage and became a hero dedicated to keeping his streets safe alongside his partner and friend Iron Fist.
