All of the princes and princesses of Amber have super-human strength and regenerative capabilities. For example, Random and Corwin are able to pick up a car that had become stuck on a soft shoulder and place it back on the road, and Corwin is able to regenerate his eyes after they are burned out, although it takes him almost five years. Corwin seems to have the fastest regenerative capabilities in the royal family, something he contemplates after his escape from the dungeons of Amber.
