Auxiliary Organs – The character has extra organs that give the character advantages.
Klingons have multiple redundancy in their organs, a principle the Klingon’s call brak’lul. This allowed Klingons to survive severe injuries in battle. They had twenty-three ribs, two livers, an eight chambered heart, three lungs, and even redundant neural function and multiple stomachs. Some geneticists believed that the extra organs, notably the third lung, evolved to give Klingons greater stamina on the battlefield. Below is a diagram of the anatomy of the hearts of various species. Notice that the Klingon heart has three chambers as opposed to two for humans.
Midnighter (DC) has an extra heart (Midnighter V1 #1).
