After being critically wounded[45], Hank's body undergoes a secondary mutation, jumpstarted by Sage. The result is a more feline appearance equivalent to that of a big cat. His strength, speed, stamina, sturdiness, and senses increase further with this change. He gains cat-like agility, flexibility, coordination, and balance, and all his senses are enhanced to twenty times that of a normal human being. In addition, Beast develops an accelerated healing factor that allows him to repair mild to moderate injuries within the span of a few hours. However, as his hands and feet change from simian to feline (going from a normal human set of four fingers to just three, retaining the opposable thumb), he loses his superhuman dexterity.
